Install dependencies -(The Windows command downloads the toolbox as a zip on purpose, so it works on a machine with no git installed. The installer sets up git for you during setup. Safe to paste as many times as you like: it skips the download when the toolbox is already there, and if an earlier attempt died partway and left a half-finished folder, it downloads again and finishes the job rather than assuming it was already done. If it tells you Claude Code is not installed yet, do the [start page](https://jaredrhod.com/start) first. Heads up for that step on Windows: the Claude Code installer downloads about 330 MB and prints nothing at all while it does, so leave that window alone until it says Installation complete.) +```powershell +$env:Path = "C:\Users\$env:USERNAME\.local\bin;$env:Path" +cd backtalk +uv sync --inexact +``` -Claude Code opens with the installer already talking to you. (The agent lives in a folder right in your home directory on purpose: on Macs, things that run in the background out of Documents get silently blocked by the system.) Everything after that is a conversation: it asks for your agent's name and personality (or hands you mine, Jarvis, ready to use), which pieces you want, and where your notes live. It does the installing, the configuring, and the wiring itself. +### 4. Launch -## Already built some of this? +Double-click `start.bat` or run: -Then you're exactly who this was designed around. If you set up a memory vault, a voice system, or a visualizer before, including the ones my old prompts had your AI hand-build, the wizard adopts before it installs: +```powershell +.\start.bat +``` -- **Your agent's identity and your vault are yours.** Found, kept, never rebuilt, never moved. No questions you already answered. -- **Hand-built voice lines and visualizers get honestly replaced**, because these repos carry a year of fixes and keep improving with a `git pull`, while a hand-built version is frozen the day it was written. Your old build stays on disk, untouched. Nothing you made is ever deleted. -- **Except your visualizer scene, which gets promoted.** If your AI built you a custom scene back then, the wizard copies it into the visualizer's gallery as your own face, sitting right beside mine. +Hold the **Home** key (or say *"go hands free"*) and speak. June answers through your speakers. -## After setup +Say **"goodbye June"** to hang up. -- **Use your agent:** the wizard leaves three shortcuts on your Desktop, named after your agent. **Chat** opens a typed session, terminal only. **Talk** starts the voice and the face. **Barehands** starts the voice and the hands board (the board is the screen in that mode). Double-click the mood you want; Ctrl-C in the window stops it. (They just run `fullstack-agent/start.sh`, or `start.bat` on Windows, if you ever prefer the terminal.) -- **Something broken or confusing? Ask your agent to fix it.** Seriously. Open the chat and describe the problem. Every repo here ships a troubleshooting guide written for your agent to read, and your agent is instructed during setup to do the fixing itself. This is the part everyone finds out late: you never have to debug this stack yourself. -- **Update everything:** `./fullstack-agent/update.sh` on macOS. On Windows, ask your agent: "update everything and tell me what changed." Your files live outside the repos, so updates never touch who your agent is or what it remembers. -- **Daily habit:** open Claude Code in your agent's folder. That's where it lives. +## Voice console commands -## The fine print that matters +These exact phrases, spoken alone, control the session: -- The wizard never deletes, overwrites, or moves anything you built. Replacements retire the old thing in place and say so. -- Your vault stays wherever it already lives. Pieces connect by configuration paths, not by relocation. -- Requirements per piece: the voice needs a mic and about 1 GB of local models on first run; the hands need a webcam and Chrome; the mind and face need nothing but Python 3, which ships with macOS and most Linux distributions. **Windows ships none**, and the name `python` there is a Microsoft Store placeholder that passes a check and then exits without running, so the face and the hands each carry a `run.bat` that finds a working interpreter or says plainly that there is not one.

Open a new terminal (PowerShell on Windows), go back to the toolbox folder (`cd ~/my-agent/fullstack-agent`, or on Windows `cd $HOME\my-agent\fullstack-agent`), and run: - -``` -claude --continue -``` - -That reopens your most recent session with its memory intact; tell it "we got cut off, keep going with the setup." If it can't find a session to continue, run `claude "set me up"` instead: the installer starts over, finds everything already downloaded, and skips ahead instead of redoing it. - -## The install command opened Claude Code, but it acts like nothing's there - -Then the download step failed before Claude Code started, and the error is in your terminal scrollback, right above where Claude opened. Type `/exit`, scroll up, and read it. On a Mac, a "developer tools" dialog may be waiting for an Open/Install click (that installs git; click Install and paste the command again). On Windows the command downloads a zip and needs no git, so a failure there is usually network. Fix what the message says, then paste the install command again. - -## Windows says "claude is not recognized," or the Claude Code install "isn't doing anything" - -Both are the same story. The Claude Code installer on Windows (the [start page](https://jaredrhod.com/start) command) downloads about 330 MB and prints nothing while it does: no progress bar, just a blinking cursor, for a few minutes, longer on slow wifi. People close the window because it looks dead, and then nothing is installed, so the next paste says `claude` is not recognized. Paste the start page command again and leave the window alone until it prints "Installation complete!" and then "All set." Then come back here and paste the install command again. It is safe to re-run: it skips the download it already did. - -## The Mac says "xcrun: error: invalid active developer path" - -Your Mac is missing Apple's Command Line Tools, which git needs. One command fixes it: run `xcode-select --install` in the same terminal, click Install on the popup, wait the few minutes it takes, then paste the install command again. This also shows up on Macs that recently upgraded macOS, because the upgrade can clear the tools; the same command puts them back. - -## Claude opened a welcome screen (or asked me to log in) instead of setting up - -Then this is your first-ever launch of Claude Code, and it runs its own one-time setup before anything else can happen: pick a text style, choose "Claude account with subscription" as the sign-in method (not the Console option, that's pay-per-use developer billing), and log in through your browser. Your "set me up" from the install command didn't survive that detour. No harm done: once you're signed in, paste the install command again and the wizard starts talking. - -## The face sits at idle while the voice talks - -The wiring is one config line, plus a restart. Check both: - -1. `ai-visualizer/ai-visualizer.json` should have `"bus_dir"` pointing at your backtalk folder. (The same wire can run from the other side instead: `"signals_dir"` in `backtalk/backtalk.json` pointing at the visualizer folder. One direction, not both.) -2. Restart the visualizer server after any config change (Ctrl-C the stack, run start.sh again). Config edits only take effect on restart. - -While the agent speaks, the backtalk folder should contain fresh `.voice_state` and `.voice_waveform` files. If they are not appearing, the problem is on the voice side; work backtalk's own guide. - -## The greeting doesn't speak on launch - -The greeting line lives in `backtalk/backtalk.json` under `"greeting"`. If it is missing or empty, the launch is silent by configuration. The voice piece itself failing to start is a different problem; its terminal output says why, and its guide covers the classics. - -## start.sh says a piece is starting but nothing appears - -- The face opens a browser tab automatically, on whichever face your `ai-visualizer.json` names. If no tab appears, open `http://127.0.0.1:8790/` yourself and click your face from the gallery. That address is the picker, not a face, so going straight there and expecting the animation is the usual confusion. -- The hands never open a tab automatically (the camera page should be opened deliberately): `http://127.0.0.1:8794/` in Chrome. -- Two stacks can't run at once. If a port is already busy from an earlier session, Ctrl-C the old terminal or close it, then start again. - -## My agent forgot who it is - -Your agent's identity lives in the `CLAUDE.md` in your HOME folder (the folder containing all the tool folders), and Claude Code only reads it when you open Claude Code IN that folder. Opening Claude Code inside one of the tool subfolders boots the tool's own instructions instead. Daily habit: work from the home folder. - -## I moved my agent folder somewhere else - -Everything is wired with paths, so a move breaks the wires. Open Claude Code in the new location and say: "read fullstack-agent/fullstack-agent.md and re-run the wiring phase." Rewiring takes a minute and touches only the config paths. - -## Updates - -`./fullstack-agent/update.sh` pulls every piece.

Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below.

Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/ai-visualizer/README.md b/ai-visualizer/README.md new file mode 100644 index 0000000..6ff863a --- /dev/null +++ b/ai-visualizer/README.md @@ -0,0 +1,106 @@ +# ai-visualizer + +> **Never used Claude Code?** Start at [jaredrhod.com](https://jaredrhod.com): pick your situation and it routes you to the right path. + +**Runs on:** Python 3 and a browser; works with any AI.

The face plays it in the browser while the agent thinks, and it automatically stays quiet when your voice line is already playing its own, so you never hear it twice.

Turn it off for good with `"thinking_sound": false` in the config. + +## On stream + +Each face is a browser page, so OBS takes it as a browser source pointed at the face URL, or you can fullscreen a window with the F key and capture that.

The four shipped faces are the reference. + +## The fine print that matters + +- The listening visuals (the amber ribbon, the mic gauges) use your microphone if you allow it, purely for the on-screen meter. Deny the permission and everything still works; those meters just run flat. +- The server binds to 127.0.0.1 only and serves nothing outside this folder.

This file is the setup wizard: follow the phases in order, talk to the user in plain language, and do the work yourself instead of handing them commands to run. One question at a time. + +## What you are setting up + +A folder of self-contained browser faces plus one standard-library Python server (`server.py`). The server reads a tiny signal bus (`.voice_state`, `.voice_waveform`, `.voice_loading_pid`) and the faces animate from it. There are no dependencies to install. Configuration lives in `ai-visualizer.json`; if it doesn't exist yet, create it by copying `ai-visualizer.json.example` (their copy is deliberately untracked, so updates can never touch it). + +## Phase 1: Prove the install + +Check that Python 3 exists (`python3 --version`, or on Windows `py --version` then `python --version`). If it's missing, help them install it before anything else. + +Start the server (`./run.sh` on Mac and Linux, `run.bat` or `python server.py` on Windows) and confirm the configured face opens in the browser; the server prints both the root URL and the page it opens. Leave it running. + +## Phase 2: Pick the face and the name + +Ask what their agent is called (that name goes on the chip and in every HUD; the default is JARVIS) and set `"name"` in `ai-visualizer.json`. + +Send them to the gallery (the root URL) and have them click through the demos. Ask which face should be the default and set `"face"` to its folder name: `board`, `radial`, `rain`, or `neural`. If they have a handle they want in the neural core's chrome, set `"badge"`; otherwise leave it empty. + +If they pick the rain face, offer the swap: any portrait on a black background dropped in as `assets/face.png` becomes the face in the code. + +## Phase 3: Wire the voice + +Ask whether they run [backtalk](https://github.com/jaredrhod/backtalk) (or another voice line that writes the `.voice_*` bus files). + +- **Yes, backtalk:** find its folder. Either set `"bus_dir"` here to that folder, or set `"signals_dir"` in their `backtalk.json` to this folder. One direction, not both. Restart whichever side changed. +- **No voice line:** that's fine. The faces run standalone on demo mode (`?demo=1`), and the server's mock mode (`--mock speaking`) fakes a live bus. Mention backtalk once as the natural next piece and move on. + +## Phase 4: The thinking sound + +`assets/thinking.wav` plays in the browser while the agent thinks. Ask if they want it. If not, set `"thinking_sound": false`. If they use backtalk and prefer the sound from the voice line instead, point backtalk's `"thinking_sound"` config at this repo's `assets/thinking.wav` and leave the browser side on; the bus deference means it never plays twice. + +## Phase 5: Test-fire + +Restart the server. Then, in order: + +1. Open the default face. It should idle with visible life, not a frozen frame. +2. Run `./run.sh --mock speaking` (or `python server.py --mock speaking`) and confirm the face performs. +3. If a voice line is wired: back to the real server, have them say something to their agent, and watch the face listen, think, and speak in sync. + +If any step fails, `TROUBLESHOOTING.md` has the ladder; climb it with them instead of guessing. + +## Phase 5.5: Tell them what else this connects to + +They have a face now. Before you hand over, tell them honestly what it is missing, because a face alone is the least of what this does. Right now, with no voice line wired in, the visualizer is running demo mode: pretty, but it is not their agent. Shape the rest of this to what they actually have. + +**The Jarvis stack is the first three pieces; the hands are the optional extra. Say what each one IS, literally, before you say why anyone would want it.** No metaphors, no teasing. Explain the ones they do not have yet: + +- **The memory (ai-memory-vault).** A folder of plain text files on their computer. Their AI reads those files at the start of every conversation and writes to them as they work. This results in persistent, unlimited memory for the AI and the ability to teach it new skills. +- **The voice (backtalk).** A program that runs on their computer. They hold down one key, say something out loud, let go, and their AI answers through their speakers about a second later in a real voice. It is the same AI, in the same folder, with the same memory. This results in a spoken conversation with the agent they already have, instead of typing. +- **The face (ai-visualizer).** A web page that opens full screen and animates while the AI works. Four designs come with it, including the circuit board from the videos. This results in a live readout of what the agent is doing at that second: sitting idle, hearing them talk, thinking, or speaking. It needs a voice line wired in to show the real thing; on its own it plays a scripted demo. +- **The hands (barehands), the optional extra.** A web page that uses their webcam to watch their hands. Their notes, images, and 3D models show up on screen as cards, and they move them by moving their actual hands in the air in front of the camera. Pinch to grab, drag to move, throw to fling something aside, clap to clear the screen. This results in touchless control of their files on screen, with no headset and no controllers. + +**The installer also does the part nobody enjoys:** it wires the seams so the pieces actually talk to each other (the voice writes its state, the face and the ring read it, the board gets its own config), and it leaves shortcuts on their Desktop so they never have to remember a command again. + +**Two honest paths, and say which one fits them:** + +1. **They want ONE more piece and nothing else.** Fastest route: say the sentence to you, right here, right now. Each repo installs from one line, for example *"clone https://github.com/jaredrhod/barehands.git, then read barehands/barehands.md and set me up."* You do it in this session and they are done. +2. **They want the pieces WIRED TOGETHER, plus the Desktop shortcuts.** That is what the full installer is for. It finds what they already have, keeps it exactly where it is, adds only what is missing, and connects everything. It never duplicates a piece they already use and it never deletes anything they built. + +**If they choose the installer, be precise about how it runs, because this trips people up:** it has to start in a NEW terminal window (PowerShell on Windows), not inside this session. That is not a technicality: the installer only becomes the installer when it opens in its own folder, and it will interview them from scratch about which pieces they want. + +Give them the command for their machine: + +Mac and Linux: +``` +mkdir -p ~/my-agent && cd ~/my-agent && git clone https://github.com/jaredrhod/fullstack-agent && cd fullstack-agent && claude "set me up" +``` + +Windows (PowerShell): +``` +$d="$env:USERPROFILE\.local\bin"; if (Test-Path "$d\claude.exe") { $env:Path="$d;$env:Path" }; New-Item -ItemType Directory -Force -Path $HOME\my-agent | Out-Null; cd $HOME\my-agent; if (-not (Test-Path fullstack-agent\fullstack-agent.md)) { Invoke-WebRequest https://github.com/jaredrhod/fullstack-agent/archive/refs/heads/main.zip -OutFile fsa.zip; Expand-Archive fsa.zip . -Force; New-Item -ItemType Directory -Force -Path fullstack-agent | Out-Null; Get-ChildItem fullstack-agent-main -Force | Copy-Item -Destination fullstack-agent -Recurse -Force; Remove-Item fullstack-agent-main -Recurse -Force; Remove-Item fsa.zip }; cd fullstack-agent; if (Get-Command claude -ErrorAction SilentlyContinue) { claude "set me up" } else { Write-Output "Claude Code is not installed yet. Install it first at https://jaredrhod.com/start then paste this again." } +``` + +Tell them what to expect: a fresh Claude Code session opens with the installer already talking. It asks their name, who their agent should be, and which pieces they want. Anything they already have gets found and kept. Their visualizer config gets picked up and wired to the voice, so the face starts performing their real conversation instead of a demo. + +**Then point them at the room.** Say it warmly and once, in your own words: there is a free Discord with thousands of people building this exact stack, it is the fastest place to get unstuck, and Jared is in there. https://discord.gg/YSdsqMv3V8 . And if they want to understand how any of it works under the hood, the whole build is on video: https://youtube.com/@jaredrhod + +Offer all of this, do not push it. If they say "just this piece for now," tell them good choice and get out of the way. + +## Phase 5.75: Leave them an icon + +They should never have to open a terminal to put the face on screen. Before handing over, put a launcher on their Desktop named after their agent, and **test it by double-clicking it with them.** Never hand over an untested shortcut. + +This one is short, because `server.py` already opens the browser itself: the launcher only has to `cd` to this folder and run it. Leave the window visible or minimized (**never hidden**: a hidden background launcher looks like malware to antivirus, and closing the window is how they stop the face). + +**macOS (`.command`), and this line is MANDATORY:** + +```bash +#!/bin/bash +export PATH="$HOME/.local/bin:/opt/homebrew/bin:/usr/local/bin:$PATH" +``` + +A double-clicked `.command` launches with a bare system PATH containing only the folders macOS ships, and their shell profile never runs. If they installed Python through Homebrew, `python3` lives outside those folders and the icon fails **silently**: the window flashes and closes, with no error anyone can read. Then `cd` to the ai-visualizer folder and run `./run.sh`. Make the file executable, and warn them once that the first double-click may ask permission; that is macOS being protective, click Open. + +**Windows (`.bat`):** `cd /d` to the ai-visualizer folder and run `run.bat`. Windows `.bat` files inherit the user's PATH, so no export is needed there. + +**Do NOT set this to run at login.** A server starting on every boot for someone who may want the face occasionally is presumptuous, and a hidden autostart entry is exactly the shape antivirus flags. The icon is the whole feature: they click it when they want the face. + +**A second icon beside it (macOS only): `Update `.** Same rules: the export line, a visible window, executable, tested by double-click. After the export, `cd` to the ai-visualizer folder and run `./update.sh`. The script does everything itself: shows what is arriving before applying it, wires a zip-downloaded folder to updates on its first run, and can never touch their `ai-visualizer.json`. And when you hand the icon over, say the update half out loud: "if you ever want the newest version, double-click `Update `; it shows you what changed, and it never touches your files." On Windows, skip the Update shortcut; tell them to say "pull the latest ai-visualizer and tell me what changed" in any chat session. + +If they already installed through fullstack-agent, they have these shortcuts already; skip this phase rather than making a second set. + +## Phase 6: Hand it over + +Show them the keys (F for fullscreen, Space for the board's cinematic flythrough), the SND toggle on mouse move, and where the config lives. If they stream, point them at the OBS section in the README. Tell them how updates work: new faces and fixes ship over time. On macOS, double-clicking `Update ` gets them (it shows what changed first). On any platform, "pull the latest ai-visualizer and tell me what changed" works in any session. Then get out of the way: the face runs itself from here. diff --git a/ai-visualizer/assets/VT323-OFL.txt b/ai-visualizer/assets/VT323-OFL.txt new file mode 100644 index 0000000..7874dec --- /dev/null +++ b/ai-visualizer/assets/VT323-OFL.txt @@ -0,0 +1,92 @@ +Copyright 2011, The VT323 Project Authors (peter.hull@oikoi.com) + +This Font Software is licensed under the SIL Open Font License, Version 1.1. +This license is copied below, and is also available with a FAQ at: +http://scripts.sil.org/OFL + +----------------------------------------------------------- +SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007 +----------------------------------------------------------- + +PREAMBLE +The goals of the Open Font License (OFL) are to stimulate worldwide +development of collaborative font projects, to support the font creation +efforts of academic and linguistic communities, and to provide a free and +open framework in which fonts may be shared and improved in partnership +with others. + +The OFL allows the licensed fonts to be used, studied, modified and +redistributed freely as long as they are not sold by themselves.

By contrast, +our General Public Licenses are intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + Developers that use our General Public Licenses protect your rights +with two steps: (1) assert copyright on the software, and (2) offer +you this License which gives you legal permission to copy, distribute +and/or modify the software. + + A secondary benefit of defending all users' freedom is that +improvements made in alternate versions of the program, if they +receive widespread use, become available for other developers to +incorporate. Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/backtalk/README.md b/backtalk/README.md new file mode 100644 index 0000000..b7991fd --- /dev/null +++ b/backtalk/README.md @@ -0,0 +1,102 @@ +# backtalk + +> **Never used Claude Code?** Start at [jaredrhod.com](https://jaredrhod.com): pick your situation and it routes you to the right path. + +**Runs on:** Claude Code only; the voice is built on Claude's agent SDK. The $20 Pro plan is enough. + +Talk to your Claude Code agent out loud. Hold a key, say the thing, and it answers through your speakers in a real voice about a second later, with all its tools, your project context, and its own personality. Your AI finally has something to say back. + +The hearing and the voice run local: free, offline models on your machine, no voice API keys, no per-word costs. The brain is the Claude Code you already have. On a Claude subscription, talking works like any other session and uses your plan's usage, with nothing extra to buy. This is the same voice loop I run every day, the one you see answering in about a second on my videos, shipped as working code so your agent's job is pointing it at your setup, not building it from scratch. + +## What it does + +- **Hold a key, talk, release.** Your words are transcribed locally and handed to a live Claude Code session. The reply is spoken sentence by sentence as it's generated, with first audio in about 1 to 2 seconds on warm turns. Prefer no button at all? **Hands-free listening** is one spoken sentence away ("go hands free"), and the key keeps working there as your interrupt. +- **It's YOUR agent talking.** The session runs in the folder whose CLAUDE.md defines your assistant: same name, same personality, same memory as your terminal sessions. backtalk has no personality of its own; it's a mouth and ears for whoever you already have. (No agent yet? The [ai-memory-vault](https://github.com/jaredrhod/ai-memory-vault) build ships with a ready-made personality you can keep, rename, or replace.) +- **Interrupt it.** Press the key while it's talking and it shuts up and listens. No headphones needed, because the mic only opens while you hold the key, so it never hears the speakers. +- **Type instead whenever you want.** Typing in the terminal is the same conversation, and the reply is still spoken. +- **It asks before it acts, in plain words.** When your agent wants to do something real, it asks out loud the way a person would ("I want to change a note in your vault called Recipes") and waits. An exact spoken yes approves; "details" reads you the exact command; anything else denies, with your words passed back as the reason, so "no, put that in drafts instead" actually steers it. Most read-only work passes without interrupting. Prefer auto-approve? Say "stop asking for permission" (or "turn off the permission prompts") and confirm; it changes its own config, and the first ask of every session reminds you the phrase exists. +- **The voice console.** Session control by voice, so you never go back to the keyboard: "clear the session", "compact the session", "switch to the deep model" / "back to the fast model", "set effort to low" (or medium, high, max; this one saves itself as your default), "usage report", "go hands free" / "push to talk mode" for the microphone, "stop asking for permission" / "start asking again" for approvals. Exact phrases, spoken alone. (Credit where due: this grew out of a community member's own build shared in the Discord.) +- **It can pick up where it left off.** Set `"resume_last_session": true` in the config and every launch reattaches to your previous conversation instead of starting cold, so closing the window stops costing you the thread. Off by default. And the built-in voice has a pace dial: `"speed"` in the config, 1.0 native, 1.15 brisker. (Credit where due: both grew out of a community proposal by aram-cloudstak.) +- **Music ducks while it speaks** (Spotify, macOS) and comes back up after. +- **It thinks out loud.** While the agent works, you hear the processing sound from my videos, so a pause never reads as a dead line. Silence it with `"thinking_sound": ""` in the config. + +## Install + +``` +git clone https://github.com/jaredrhod/backtalk +cd backtalk +./install.sh +``` + +The installer sets up a Python environment, the two local AI models (speech-to-text and the voice), and the one system library they need. First run downloads the models (about 1 GB total); everything after is instant. Prerequisites: [Claude Code](https://claude.com/claude-code) with a Claude subscription, and `uv` (the installer offers to install it). + +**The easy way to configure it:** open this folder in Claude Code and say *"read backtalk.md and set me up."* The wizard picks your agent folder, your key, and your voice with you, then test-fires the whole loop. + +**Already in a Claude Code session with your agent?** One sentence does the whole install: *"clone https://github.com/jaredrhod/backtalk.git, then read backtalk/backtalk.md and set me up."* Your agent runs the installer and the wizard for you. + +**The manual way:** copy `backtalk.json.example` to `backtalk.json` (your copy is untracked, so updates never touch it), then edit it. Point `agent_dir` at the folder whose CLAUDE.md is your agent, set `name` to your agent's name, pick a `ptt_key`. Then: + +``` +./run.sh +``` + +Hold the key. Talk. Let go. + +## Windows + +Windows is the newest lane, and the setup runs through the wizard instead of the shell scripts (`install.sh` and `run.sh` are Mac and Linux). Open this folder in Claude Code and say *"read backtalk.md and set me up"*: the wizard installs uv, espeak-ng, the environment, and the models natively, then launches with `uv run python -m backtalk.main`. The ElevenLabs key lives in the `ELEVENLABS_API_KEY` environment variable on Windows for now (Credential Manager support is planned). Hit something rough? The Windows notes in `TROUBLESHOOTING.md` carry the known quirks, and issues are welcome. + +## The voice + +Two engines, and the setup wizard offers you both instead of quietly defaulting. + +**Built-in (Kokoro), the free one.** Local, offline, no accounts, no per-word costs, and honestly a bit computer-sounding. The default voice is `bm_lewis`, a British male with exactly the butler register. Around 60 voices ship free; set `voice` in `backtalk.json` (the first letter picks the language: `a` is American, `b` is British, and there are Spanish, French, Hindi, Italian, Japanese, Portuguese, and Chinese voices too). + +**ElevenLabs, the natural one.** The human-sounding voice most people actually want, on your own API key. The free tier is enough to audition it; day-to-day talking runs on the paid starter plan. The wizard walks the whole thing with you: account, key into the keychain, then an audition of real voices through backtalk's own mouth until one fits. Want the exact voice from my videos? It's called **Tarquin** in the ElevenLabs voice library: search it by name and you're done hunting. Under the hood it is: set `elevenlabs.enabled` and your `voice_id` in the config, and have `ffmpeg` installed. **The key never goes in a file.** On macOS, seed it into the Keychain once with `security add-generic-password -a "$USER" -s backtalk-elevenlabs -T /usr/bin/security -w` (it prompts for the secret) and backtalk reads it from there. Linux: `secret-tool store --label backtalk service backtalk-elevenlabs`. The `ELEVENLABS_API_KEY` environment variable works as a last resort, but an export in a shell profile is a plaintext key on disk; the keychain is the grown-up path. Kokoro stays wired in as the automatic fallback, so if the cloud fails the voice degrades instead of going mute, and `logs/backtalk.log` records why. + +## Give it a face (optional) + +backtalk writes tiny state files while it listens, thinks, and speaks, so anything can watch them and react in real time. + +- **[ai-visualizer](https://github.com/jaredrhod/ai-visualizer)** is the matching face: four full-screen visualizers, including the living circuit board from my videos. Point its `bus_dir` at this folder (or set `signals_dir` here to its folder) and it performs your actual conversation, idling, listening, thinking, and speaking along with the voice. +- **[barehands](https://github.com/jaredrhod/barehands)**: point `barehands_state_dir` at its `state/` folder and the on-screen ring becomes your agent's face, breathing while idle, spinning while thinking, and pulsing with the voice while it talks. + +Mind ([ai-memory-vault](https://github.com/jaredrhod/ai-memory-vault)), mouth (this), face (ai-visualizer), hands (barehands). + +## The fine print that matters + +- **Usage:** every spoken turn is a real Claude Code turn, so a long voice session uses your plan the same way a long typing session does. The config pins the fast model tier on purpose; it's most of the speed, and it's the lighter draw. +- **Permissions: ask first, auto-approve by choice.** The default is `"ask"`: gated actions get a spoken permission check, answered by voice or by typing, and silence for about 75 seconds means no. `"bypassPermissions"` is auto-approve: the agent acts without asking, exactly like a terminal session with approvals off. Never hand-edit the file to switch; tell your agent to change it (takes effect the next time the voice line starts), or say "stop asking for permission" / "start asking again" in a voice session for a flip that happens immediately and saves itself. +- **Two microphone modes, and the words mean what you think.** Push to talk (the default): the mic is closed except while you hold the key, so nothing records in the background, ever. **Hands-free listening**: always listening with voice detection; the setup asks which you want, "go hands free" / "push to talk mode" switches live and saves itself, and the talk key still works in hands-free as your interrupt. Tradeoffs in `TROUBLESHOOTING.md`. (Hands-free is about the MICROPHONE. Approvals are a separate setting called auto-approve; the two never share a name.) +- **The talk key needs a global key listener.** For the key to work when the voice line isn't your focused window, the process has to watch keyboard events system-wide. `backtalk/ptt.py` compares each event against the one key you configured and discards the rest. It stores nothing and writes nothing anywhere. Ninety-one lines, so you can read all of it in a minute. macOS asks for Input Monitoring permission before it will run, which is the OS telling you what the program can see. +- **Pin the microphone if you wear a headset.** By default it records from the system default input, which the OS hands to a headset the moment one connects, taking your voice down the narrowband call profile and degrading what you hear at the same time. Set `"mic_device"` in backtalk.json to the input you want, by name (`"MacBook Pro Microphone"`), and the mic stays put whatever connects for output. A name that matches nothing falls back to the default with a log line rather than going mute.

Your browser choice has nothing to do with it; the visualizer only displays. +- **Nothing happens when I hold the key (macOS)**: the terminal app needs **Input Monitoring** permission: System Settings → Privacy & Security → Input Monitoring → add your terminal (Terminal, iTerm, etc.), then restart the terminal. The mic prompt is separate and appears on first recording. +- **Mic permission never appeared / recording is silent**: launch from a normal terminal window, not a background service or launcher daemon: the process inherits the *terminal's* microphone permission. Check the input device: `python -m sounddevice` lists them. +- **It records from my headset instead of the mic I wanted (and my headphone audio gets worse while I talk)**: it follows the system default input, and the OS re-points that the moment a headset with a mic connects. On Bluetooth that also drops the headset from high quality into the narrowband call profile, so the music and the voice both degrade mid-sentence. Pin it: set `"mic_device"` in backtalk.json to the input you want, **by name** (`"MacBook Pro Microphone"`). Indices are not stable, so the name is the contract; `python -m sounddevice` lists them. Exact name first, then case-insensitive substring, so `"MacBook Pro"` works too. A name matching nothing falls back to the default and logs every input it did find. (Not `stt_device`, which is the Whisper COMPUTE device, cpu or cuda.) +- **Running under WSL2 and it crashes the moment it tries to speak** (a core dump rather than an error): WSLg puts the audio socket somewhere the audio library does not look. `run.sh` links it on every launch, so this heals itself if you start with `run.sh` rather than calling Python directly. The folder it links into is wiped on reboot, which is why it is redone every time. (Credit where due: found and fixed by shavalejames-blip.) +- **My temp folder is filling up with tiny folders**: the speech engine copies its phoneme library into a fresh temp folder for every voice backend it builds, and the cleanup does not run when the process is KILLED rather than closed, which is what most launchers do. They accumulate forever. The voice line now sweeps its own leftovers at startup, so the total stays at one run's worth. It only ever removes a folder whose entire contents are that one library file. (Credit where due: found and fixed by BigpapaWarren, who had sixty of them.) +- **It stops hearing me after I connect or disconnect a headset** (and looks completely healthy while it does): the audio library caches the device list when it starts, so a device that appears or vanishes afterwards leaves a stale entry behind and every recording after that fails silently. Bluetooth headsets trigger it every time the mic opens, because they flip between listening and call modes. The voice line now rebuilds the audio system and reopens the mic when this happens, and the speaking side survives the rebuild. (Credit where due: found and fixed by CansuKhon.) +- **It hears me but answers slowly**: check `model` in `backtalk.json`. Full-size deep-work models make every reply noticeably slower; the fast tier is the point of a voice loop. Also confirm the model id is the FULL id, never a bare alias; aliases can silently resolve to an older model through the SDK's bundled CLI. +- **First reply after launch is slow**: that's the one-time prompt-cache toll, mostly hidden behind the greeting. Warm turns are the real speed. +- **It starts cold and forgets the last conversation after a restart**: that is the default (a fresh session every launch is predictable). Want it to pick up where it left off? Tell your agent to set `"resume_last_session": true` in backtalk.json. From then on every launch reattaches to the previous conversation, and a stale saved session falls back to fresh with a log line instead of breaking the launch. The saved conversation lives on your machine as a Claude Code transcript (kept for 30 days from last use by default), and a long conversation never dies from length: it compacts itself automatically, older turns becoming a summary while recent ones stay verbatim. Start over any time by saying "clear the session." +- **The voice talks too fast or too slow**: the built-in voice has a pace dial, `"speed"` in backtalk.json. 1.0 is native, 1.15 is brisker, 0.9 is slower. ElevenLabs pace lives in the `master` chain's atempo value instead. +- **Updating, or an update that complains about local changes**: run `./update.sh` in this folder (macOS), or double-click the `Update` icon if setup left one. On Windows, ask your agent: "pull the latest backtalk and tell me what changed." The updater shows what changed before applying it and can never touch your `backtalk.json`. If an older updater said "couldn't fast-forward" or mentioned local changes, run `./update.sh` once and it clears: it moves your config out of git's sight and everything flows after. +- **The voice sounds robotic**: you're hearing Kokoro's base register, or the wrong voice for the language. Try `bm_george`, `bm_daniel`, `am_michael`, `af_heart`. Remember the first letter must match the language pipeline (`b…` British, `a…` American). +- **`espeak` errors when the voice loads**: the system `espeak-ng` package is missing (the pip-bundled build inside the voice engine is broken (known upstream); the system package is the supported path). `brew install espeak-ng` / `sudo apt install espeak-ng`, then re-run. +- **Choppy or slow-motion audio on a weak machine**: lower `stt_model` to `base.en` or `tiny.en`. The playback side already buffers 0.75s ahead specifically so slow machines don't garble. +- **Two voices answering at once**: two copies are running. `./run.sh` kills the previous instance on launch; if you started one some other way, kill it. One body, one mouth. +- **Spotify stays quiet after it stops talking**: the restore is debounced ~0.5s; if the process was force-killed mid-speech the restore can be lost. It self-corrects on the next duck, or nudge the volume by hand. +- **ElevenLabs sounds worse than their website**: their site previews are mastered demo clips; the raw API never matches them. The shipped `master` ffmpeg chain closes the gap; make sure `ffmpeg` is installed, and don't set the style parameter or switch to the multilingual model for English (both make delivery slow and dull). +- **It started asking permission out loud after an update**: that is the new default (safe by default, auto-approve by choice). Say "stop asking for permission" in a voice session and confirm for an immediate, saved flip; or tell your agent to set `"permission_mode": "bypassPermissions"`, which takes effect the next time the voice line starts. The agent writes the config, never you. +- **It asked permission, then said "no answer, so I didn't do it"**: the spoken ask waits about 75 seconds, then treats silence as no. Hold the key and answer with an exact "yes" (or "go ahead", "approved") to approve, "details" to hear the exact command it wants to run, or anything else to deny; a denial's words are passed back to the agent as the reason, so spoken redirections work. Done with the checks entirely? "Stop asking for permission" and "turn off the permission prompts" both work, with a confirm. +- **A voice command didn't trigger**: console phrases match exactly, spoken alone: "clear the session", "compact the session", "switch to the deep model", "back to the fast model", "set effort to low" (or medium, high, max), "usage report", "go hands free" and "push to talk mode" (the microphone), "stop asking for permission" and "start asking again" (approvals). Extra words around them make a normal sentence for the agent instead. That guard is deliberate. +- **"Hands-free" vs auto-approve, because the words matter**: hands-free is the MICROPHONE (always listening, no button; "go hands free" / "push to talk mode"). Auto-approve is PERMISSIONS (act without asking; "stop asking for permission" / "start asking again"). They are separate settings and switch separately. +- **It answers my previous question instead of the one I just asked**: this is the interrupt-desync bug this codebase specifically armors against (`brain.reset_turn`); if you EVER see it, something has changed in the SDK. Grab `logs/backtalk.log` and file an issue; the log will show whether the stale-turn drain ran. + +## Windows notes + +- **No install.sh or run.sh:** they are Mac and Linux shell scripts. The wizard (`backtalk.md`) performs the install natively on Windows; launch with `uv run python -m backtalk.main`. +- **espeak-ng:** install it with winget or the official installer. backtalk looks for `libespeak-ng.dll` in the usual Program Files locations; if yours lives elsewhere, set `PHONEMIZER_ESPEAK_LIBRARY` to the dll's full path. +- **The ElevenLabs key** lives in the `ELEVENLABS_API_KEY` environment variable for now; Credential Manager support is planned. +- **One copy at a time:** run.sh's single-instance guard is Mac and Linux; on Windows, close the old window before starting a new one, or two voices answer one mic. +- **Speed:** `stt_device: "auto"` uses CUDA when present and CPU otherwise; CPU with `small.en` is plenty fast on a normal machine. + +## The voice went robotic again (ElevenLabs users) + +That sound is the safety net working: on any ElevenLabs failure, backtalk falls back to the built-in Kokoro voice instead of going mute. The reason is one line in `logs/backtalk.log`; look for `elevenlabs failed`. The usual causes, most common first: + +1. **Out of credits.** The free tier's monthly allowance goes fast in real conversation. Check usage on your ElevenLabs dashboard; the starter plan fixes it. +2. **The key isn't reachable.** The keychain item is `backtalk-elevenlabs` (macOS/Linux); on Windows it's the `ELEVENLABS_API_KEY` environment variable, which only newly opened programs can see, so restart the voice line from a fresh window after setting it. +3. **`ffmpeg` missing.** Run `ffmpeg -version`; if that fails, install it (`brew install ffmpeg` / `apt install ffmpeg` / `winget install Gyan.FFmpeg`). +4. **No internet.** The built-in voice covers you until it's back; nothing to fix in backtalk. + +## Hands-free listening: the tradeoff + +Hands-free listening (the setup question, `"mic_mode": "open"`, the spoken "go hands free", or the `--open-mic` launch flag) listens continuously with voice-activity detection instead of hold-to-talk. Know what you're trading: any speech in the room (a video, music with vocals, another voice assistant) can be transcribed and answered as if it were you. Push to talk is the default because the button is a perfect voice-activity detector and the mic is *closed* the rest of the time. Two things stay true in hands-free: the talk key still works (it interrupts, and holding it always gets you heard over room noise), and spoken permission checks accept only an exact "yes", so stray room audio cannot approve an action. With open speakers, answer permission checks with the button held, or wear headphones. `--barge-in` (interrupting it by talking over it) additionally requires headphones, or it hears its own reply and interrupts itself. + +## For AI assistants: the architecture in six lines + +``` +hold key -> ears.record_held (sounddevice, 16kHz int16) + -> ears.transcribe (faster-whisper, in-process, local) + -> brain.ask_stream (warm Claude Agent SDK session, + cwd = agent_dir, streams sentences) + -> mouth.say_chunk (kokoro in-process -> one long-lived + OutputStream; ElevenLabs optional) +signals.py mirrors state to .voice_* files (+ optional barehands state/) +permission_mode "ask": gated tools pause the turn and route to a spoken + yes/no (main.make_permission_gate). The LIVE + auto-approve switch is a gate flag; a session + BOOTED in bypassPermissions is real SDK bypass + and never consults the gate. The mic mode + (_MIC, ptt/open) is a separate axis: one loop, + the open mic joins the wait-set in "open" mode, + and the talk key works in both +``` + +Three land mines with warning signs on them; do not "simplify" these away: + +1. **The key-repeat filter in `ptt.py`.** The OS fires on_press continuously while a key is held; without the held-state flag, every repeat cancels the reply before it can speak. +2. **The one long-lived output stream in `mouth.py`.** A fresh stream per sentence causes onset blips or dead air on USB interfaces, Bluetooth, and streaming mixers. Interrupts pad silence into the stream; they never close it. +3. **`brain.reset_turn` in `brain.py`.** The SDK has one shared message stream with no query/response pairing; an interrupted turn leaves its leftovers buffered, and without the drain every later answer is off by one question. +4. **The pending-permission routing in `main.py`.** While a spoken permission ask is waiting, the next utterance is the ANSWER: it must never be treated as an interrupt or a new turn, or the paused turn gets cancelled out from under the SDK. The same goes for the live auto-approve switch: the CLI refuses a live flip INTO bypassPermissions (it needs the danger flag at launch), which is why auto-approve is a gate flag instead of an SDK mode change. +5. **The mic generation counter (`_MIC["gen"]`).** A live switch between push-to-talk and hands-free listening bumps it; the open mic's abort callable watches it, and any capture born under an old generation is discarded. Without it, a switch back to push-to-talk leaves an open mic capturing one final utterance that then fires as a ghost turn. + +## Verify a working install + +1. `./run.sh` → greeting speaks. +2. Hold the key, ask something, release → answer within ~2s. +3. Interrupt mid-reply with the key → it stops within a syllable. +4. Interrupt, then ask something NEW → the answer matches the NEW question (repeat 3×: that's the stream drain proving itself). +5. Ask something that needs a tool ("what's in my notes about X") → it speaks filler within a couple of seconds, then the answer. +6. Type a message in the terminal → spoken reply, same conversation. +7. Say "usage report" → it speaks turns and tokens (plus cost when the API reports one). +8. In ask mode: request a small file write → the spoken permission check plays → "yes" proceeds, and a second attempt answered "no" stands down. +9. Say "goodbye " → sign-off plays, process exits, music restores. diff --git a/backtalk/assets/thinking.wav b/backtalk/assets/thinking.wav new file mode 100644 index 0000000..3bb9465 Binary files /dev/null and b/backtalk/assets/thinking.wav differ diff --git a/backtalk/backtalk.json.example b/backtalk/backtalk.json.example new file mode 100644 index 0000000..1ba4fbe --- /dev/null +++ b/backtalk/backtalk.json.example @@ -0,0 +1,7 @@ +{ + "agent_dir": "~", + "name": "Assistant", + "ptt_key": "home", + "voice": "bm_lewis", + "stt_model": "small.en" +} diff --git a/backtalk/backtalk.md b/backtalk/backtalk.md new file mode 100644 index 0000000..72b1247 --- /dev/null +++ b/backtalk/backtalk.md @@ -0,0 +1,153 @@ +--- +name: backtalk +description: Interactive setup for backtalk, the voice loop that lets you talk to your Claude Code agent out loud.

Do not improvise. +version: 1.0 +author: Akhil +--- + +# backtalk: setup + +By **Jared Rhodenizer** (@jaredrhod) · github.com/jaredrhod/backtalk + +You are reading a system builder file. You, an AI assistant, will follow it to set up backtalk for the person who opened it. Do not summarize this file. Do not describe it. Execute it. + +## What you are setting up + +backtalk is a voice loop: they hold a key and talk, their words are transcribed locally, handed to a live Claude Code session, and the reply is spoken aloud in a real voice, sentence by sentence, about a second to first audio. **The session runs in THEIR agent's folder, so the thing speaking is their existing assistant** (its name, personality, and memory), not a new one. backtalk has no personality of its own; you are configuring a mouth and ears. + +Everything runs local by default: free on-device models for both hearing and speaking, no API keys. Work through the phases in order, one question at a time. Warm, confident, premium unboxing, not a config chore. + +## Phase 1: Prove the install + +1. Confirm you're in the repo folder (it contains `backtalk.json.example`, `run.sh`, `install.sh`). If not, have them `cd` here and restart. If `backtalk.json` doesn't exist yet, create it now: copy `backtalk.json.example` to `backtalk.json`. Their copy is deliberately untracked, so updates can never touch it. +2. If `.venv/` doesn't exist, run `./install.sh` for them and narrate what it's doing (environment, the espeak-ng system library, ~1GB of speech models, first run only). If it exists, `./install.sh` is still safe to re-run and completes in seconds. +3. **Windows:** the shell scripts are Mac and Linux; YOU are the installer here. Do the equivalent natively: install uv if missing (PowerShell: `irm https://astral.sh/uv/install.ps1 | iex`), install espeak-ng (`winget install eSpeak-NG.eSpeak-NG` -- that exact id, because a bare `espeak-ng` does not resolve for an exact install -- or the installer from github.com/espeak-ng/espeak-ng/releases), then `uv venv .venv` and `uv pip install -e .` in this folder, and prefetch the models with the same warm() snippet install.sh uses. Launch with `uv run python -m backtalk.main` instead of run.sh. Write any path you hand these tools with FORWARD slashes: they work everywhere in both Python and Node on Windows, and they survive the trip through bash and JSON that eats backslashes. If the voice fails to load, find `libespeak-ng.dll` (usually under Program Files\eSpeak NG) and set `PHONEMIZER_ESPEAK_LIBRARY` to its full path. Adapt as the machine demands; read errors and respond, that is why you are the installer. +4. On macOS, tell them now, before the first run surprises them: the first recording will pop a **Microphone** permission prompt, and the hold-to-talk key needs **Input Monitoring** for their terminal app (System Settings → Privacy & Security → Input Monitoring). Have them grant Input Monitoring *now* and restart the terminal if they add it. + +## Phase 2: Find their agent + +Ask: **"Do you already have a Claude Code agent, a folder with a CLAUDE.md that defines an assistant (a name, a personality)?"** + +Never default `agent_dir` to whatever folder Claude Code happens to be running in: an unrelated project is not an agent, and wiring the voice to one gives the person a voice with no one behind it. If there is no real agent folder, use one of the two paths below. + +- **Yes:** get the folder's path. That's `agent_dir`. Ask the agent's name for `name` (it builds the quit phrases, "goodbye " hangs up, and labels the log). +- **No:** point them at **ai-memory-vault** (github.com/jaredrhod/ai-memory-vault), the full build that creates an agent with persistent memory, and it ships with a ready-made personality (Jarvis) they can keep, rename, or replace. Offer to pause here while they run that first (it's the better order), or set `agent_dir` to a folder of their choice with a minimal CLAUDE.md you write together now (a name, a role, a few lines of personality) as a starter. + +## Phase 3: The key and the voice + +1. **The microphone mode, in plain words, because "hands-free" is the thing people ask for by name.** Two ways to talk: **push to talk** (the default and the recommendation: hold a key, speak, release; the mic is closed the rest of the time, so room audio and their own speakers can never trigger the agent) or **hands-free listening** (always listening with voice detection: no button, and also no filter, so a video, music with vocals, or another person in the room can trigger it, and with open speakers it can hear itself; headphones help). Tell them the honest pair of facts: the talk key still works in hands-free (it interrupts, and holding it always gets them heard), and they can switch any time by saying "go hands free" or "push to talk mode" mid-session. Ask which they want and set `mic_mode` ("ptt" or "open") yourself. +2. **The key.** Default is `home`. Ask what they want to hold to talk (in hands-free listening it is still the interrupt): a key they never type with is best (`home`, `end`, `f13`–`f19`, `right_alt`). Set `ptt_key`. +3. **The voice engine. Offer this choice to EVERYONE, unprompted; it is not a power-user extra, and skipping it leaves people on a voice they may quietly dislike.** Two engines, one honest sentence each: + - **Built-in (Kokoro):** free forever, runs on their computer, works offline, and sounds decent but noticeably computer-generated. + - **ElevenLabs:** the natural, human-sounding voice, running on their own ElevenLabs account. The free tier includes enough speech per month to hear it and decide; regular daily talking runs on the paid starter plan (about five dollars a month; have them check current pricing at elevenlabs.io). Needs internet and `ffmpeg`. + + Recommend hearing both before choosing; the audition takes a minute. Never silently default to the built-in voice. Whichever they pick, the built-in voice stays installed as the automatic fallback, so the voice degrades instead of going mute if the cloud ever fails, and `logs/backtalk.log` records why. +4. **If they pick the built-in voice:** default is `bm_lewis` (British male, the butler register). Offer to audition: run `python -m backtalk.mouth "Hello there. This is what I sound like."` with the venv python, changing `voice` in `backtalk.json` between runs. Pace is adjustable too: the `speed` key (1.0 native, 1.15 brisker) if the voice feels slow to them. Other good English options: `bm_george`, `bm_daniel`, `bm_fable`, `am_michael`, `af_heart`, `af_bella`. The first letter is the language pipeline; keep it matched. +5. **If they pick ElevenLabs, walk them through it end to end; never hand them a to-do list.** + - **Account and key:** they sign up at elevenlabs.io (the free tier is fine to start) and create an API key (profile menu, API Keys). + - **Seed the key into the system's secret store. The key never goes in a config file, any file, ever, and never gets pasted into this chat.** macOS: run `security add-generic-password -a "$USER" -s backtalk-elevenlabs -T /usr/bin/security -w` and have THEM paste the key at the terminal prompt. Linux: `secret-tool store --label backtalk service backtalk-elevenlabs`. Windows: no native store is wired yet, so the `ELEVENLABS_API_KEY` environment variable is the path: have THEM run `setx ELEVENLABS_API_KEY "their-key-here"` in their own PowerShell window, tell them plainly that stores the key readable on disk for their user account, and that newly opened programs see it (so start the voice line from a fresh window). + - **Pick the voice by ear, never by making them hunt IDs.** Fetch their available voices live from the API: `GET https://api.elevenlabs.io/v1/voices` with the `xi-api-key` header, reading the key back out of the store you just seeded. Every account includes ElevenLabs' premade voices with names, descriptions, and `voice_id`s. If they want the exact voice from Jared's videos, skip the hunt: it is called **Tarquin** in the ElevenLabs voice library; search it by name and use its voice_id. Otherwise offer a shortlist matched to what they want (male or female, accent, register), set `elevenlabs.enabled: true` and the first candidate's `voice_id` in `backtalk.json`, and audition through backtalk's own mouth: `python -m backtalk.mouth "Hello there. This is what I sound like."` Swap the `voice_id` and repeat until they're happy. Write the winner. + - **Confirm `ffmpeg` is installed:** `brew install ffmpeg` (macOS) / `apt install ffmpeg` (Linux) / `winget install Gyan.FFmpeg` (Windows), then verify `ffmpeg -version` runs from a fresh shell. + +## Phase 4: Optional integrations + +Ask about each, configure what they want: + +- **A face:** two companions read the signal bus this repo writes. + - **ai-visualizer** (github.com/jaredrhod/ai-visualizer): four full-screen faces including the circuit board. Either set `signals_dir` here to that repo's folder, or set `bus_dir` there to this folder. One direction, not both. + - **barehands** (github.com/jaredrhod/barehands): set `barehands_state_dir` to its `state/` folder path and the on-screen ring becomes the agent's face, live with the voice. + If they have neither, one sentence: "there are companion repos that give it a face on screen, for later if you want." +- **Extra folders:** anything beyond `agent_dir` the agent should reach in voice sessions (a notes vault, a projects folder) goes in `extra_dirs`. +- **Permissions (ask which mode, then YOU write their choice).** The default is `"ask"`: when the agent wants a gated action mid-conversation, it asks OUT LOUD in plain words (never paths or command syntax; "details" reads the literal form on request) and waits; an exact spoken yes approves, any other answer denies and becomes the reason it passes back; silence for about 75 seconds means no; most read-only work passes without asking. The first ask of a session mentions the off switch by name. Explain that, then offer the alternative honestly: `"bypassPermissions"` is fully hands-free, which is smoother and also means the agent can act on a mistake without a checkpoint. Call the hands-free-of-permissions mode by its real name, **auto-approve**, and never "hands-free" (that word belongs to the microphone). Ask which they want and write it into `backtalk.json` yourself. Tell them it is never welded shut: they can tell their agent to change it in any session (it takes effect at the next launch), or say "stop asking for permission" (then "confirm") or "start asking again" inside a voice session for an immediate flip that saves itself. +- **Pick up where you left off:** ask whether they want the conversation to survive restarts. Default is off (a fresh session every launch); `"resume_last_session": true` makes every launch reattach to the previous conversation. One honest sentence each way: resume means the morning session still remembers last night; fresh means a clean slate every time, and the vault carries the durable memory regardless. +- **The thinking sound:** on by default, playing `assets/thinking.wav` while the agent works. Point `thinking_sound` at any other wav/mp3 to swap it, or set it to `""` for silence. If they also run ai-visualizer, leave this on and its browser player stays quiet automatically, so the sound never doubles. + +## Phase 5: Test-fire the loop + +Run `./run.sh` for them and walk the checklist out loud, one step at a time: + +1. Greeting speaks. +2. Hold the key, "ask it anything", release. Answer inside ~2 seconds. +3. Interrupt it mid-reply with the key. It stops within a syllable. +4. Interrupt, then immediately ask something NEW, and confirm the answer matches the NEW question. **Do this three times.** (This is the interrupt-desync armor proving itself; it's the test naive voice builds fail.) +5. Ask something that needs a tool; it should speak filler, then the answer. +6. Type a line in the terminal: spoken reply, same conversation. +7. Say "usage report": it speaks the session's turns and tokens, plus rough cost when the API reports one. +7b. If they chose push to talk, say "go hands free": hands-free listening comes on with a spoken explanation; an unheld sentence reaches the agent; "push to talk mode" brings the button back. (Chose hands-free at setup? Run it the other way around.) +8. If they chose ask mode: give it a small task that writes a file, hear the spoken permission check in plain words, say "details" and hear the literal command, answer yes, and watch it proceed. Then another, answer no, and hear it stand down. +9. "Goodbye ": sign-off, clean exit. + +If any step fails, `TROUBLESHOOTING.md` has the fix; read it and apply it rather than improvising. + +## Phase 5.5: Tell them what else this connects to + +They have a voice now, and they just heard it work. Before you hand over, tell them what it pairs with. The most important one: if they have no memory vault, the thing they just talked to is a stranger every morning. Shape the rest to what they have. + +**The Jarvis stack is the first three pieces; the hands are the optional extra. Say what each one IS, literally, before you say why anyone would want it.** No metaphors, no teasing. Explain the ones they do not have yet: + +- **The memory (ai-memory-vault).** A folder of plain text files on their computer. Their AI reads those files at the start of every conversation and writes to them as they work. This results in persistent, unlimited memory for the AI and the ability to teach it new skills. +- **The voice (backtalk).** A program that runs on their computer. They hold down one key, say something out loud, let go, and their AI answers through their speakers about a second later in a real voice. It is the same AI, in the same folder, with the same memory. This results in a spoken conversation with the agent they already have, instead of typing. +- **The face (ai-visualizer).** A web page that opens full screen and animates while the AI works. Four designs come with it, including the circuit board from the videos. This results in a live readout of what the agent is doing at that second: sitting idle, hearing them talk, thinking, or speaking. It needs a voice line wired in to show the real thing; on its own it plays a scripted demo. +- **The hands (barehands), the optional extra.** A web page that uses their webcam to watch their hands. Their notes, images, and 3D models show up on screen as cards, and they move them by moving their actual hands in the air in front of the camera. Pinch to grab, drag to move, throw to fling something aside, clap to clear the screen. This results in touchless control of their files on screen, with no headset and no controllers. + +**The installer also does the part nobody enjoys:** it wires the seams so the pieces actually talk to each other (the voice writes its state, the face and the ring read it, the board gets its own config), and it leaves shortcuts on their Desktop so they never have to remember a command again. + +**Two honest paths, and say which one fits them:** + +1. **They want ONE more piece and nothing else.** Fastest route: say the sentence to you, right here, right now. Each repo installs from one line, for example *"clone https://github.com/jaredrhod/barehands.git, then read barehands/barehands.md and set me up."* You do it in this session and they are done. +2. **They want the pieces WIRED TOGETHER, plus the Desktop shortcuts.** That is what the full installer is for. It finds what they already have, keeps it exactly where it is, adds only what is missing, and connects everything. It never duplicates a piece they already use and it never deletes anything they built. + +**If they choose the installer, be precise about how it runs, because this trips people up:** it has to start in a NEW terminal window (PowerShell on Windows), not inside this session. That is not a technicality: the installer only becomes the installer when it opens in its own folder, and it will interview them from scratch about which pieces they want. + +Give them the command for their machine: + +Mac and Linux: +``` +mkdir -p ~/my-agent && cd ~/my-agent && git clone https://github.com/jaredrhod/fullstack-agent && cd fullstack-agent && claude "set me up" +``` + +Windows (PowerShell): +``` +$d="$env:USERPROFILE\.local\bin"; if (Test-Path "$d\claude.exe") { $env:Path="$d;$env:Path" }; New-Item -ItemType Directory -Force -Path $HOME\my-agent | Out-Null; cd $HOME\my-agent; if (-not (Test-Path fullstack-agent\fullstack-agent.md)) { Invoke-WebRequest https://github.com/jaredrhod/fullstack-agent/archive/refs/heads/main.zip -OutFile fsa.zip; Expand-Archive fsa.zip . -Force; New-Item -ItemType Directory -Force -Path fullstack-agent | Out-Null; Get-ChildItem fullstack-agent-main -Force | Copy-Item -Destination fullstack-agent -Recurse -Force; Remove-Item fullstack-agent-main -Recurse -Force; Remove-Item fsa.zip }; cd fullstack-agent; if (Get-Command claude -ErrorAction SilentlyContinue) { claude "set me up" } else { Write-Output "Claude Code is not installed yet. Install it first at https://jaredrhod.com/start then paste this again." } +``` + +Tell them what to expect: a fresh Claude Code session opens with the installer already talking. It asks their name, who their agent should be, and which pieces they want. Anything they already have gets found and kept. Their voice config gets found and kept, and the face gets pointed at the status files this install already writes. + +**Then point them at the room.** Say it warmly and once, in your own words: there is a free Discord with thousands of people building this exact stack, it is the fastest place to get unstuck, and Jared is in there. https://discord.gg/YSdsqMv3V8 . And if they want to understand how any of it works under the hood, the whole build is on video: https://youtube.com/@jaredrhod + +Offer all of this, do not push it. If they say "just this piece for now," tell them good choice and get out of the way. + +## Phase 5.75: Leave them an icon + +They should never have to remember a command to start talking to their agent. Before handing over, put a launcher on their Desktop named after their agent, and **test it by double-clicking it with them.** Never hand over an untested shortcut. + +The launcher just starts the voice line the way they would from the terminal, in a window they can see and close (**visible or minimized, never hidden**: a hidden background launcher looks like malware to antivirus, and closing the window is how they stop it). Point its output at the existing log so a failed start stays readable. + +**macOS (`.command`), and this line is MANDATORY:** + +```bash +#!/bin/bash +export PATH="$HOME/.local/bin:/opt/homebrew/bin:/usr/local/bin:$PATH" +``` + +A double-clicked `.command` launches with a bare system PATH where `uv` does not exist, and their shell profile never runs. Without that export the icon fails **silently**: the window flashes and closes, with no error anyone can read. Then `cd` to the backtalk folder and run `./run.sh`. Make the file executable, and warn them once that the first double-click may ask permission; that is macOS being protective, click Open. + +**Windows (`.bat`):** `cd /d` to the backtalk folder, run `uv sync -q --inexact` (the self-repair line: it heals a drifted or half-installed environment in under a second when nothing is wrong), then run `uv run python -m backtalk.main`. Windows `.bat` files inherit the user's PATH, so no export is needed there. End the file with an error hold so a crash stays readable instead of the window vanishing: `if errorlevel 1 pause`. + +**Do NOT set this to run at login.** A voice line starting on every boot for someone who may use it occasionally is presumptuous, and a hidden autostart entry is exactly the shape antivirus flags. The icon is the whole feature: they click it when they want to talk. + +**A second icon beside it (macOS only): `Update `.** Same rules: the export line, a visible window, executable, tested by double-click. After the export, `cd` to the backtalk folder and run `./update.sh`. The script does everything itself: shows what is arriving before applying it, wires a zip-downloaded folder to updates on its first run, and can never touch their `backtalk.json`. And when you hand the icon over, say the update half out loud: "if you ever want the newest version, double-click `Update `; it shows you what changed, and it never touches your files." On Windows, skip the Update shortcut; tell them to say "pull the latest backtalk and tell me what changed" in any chat session. + +If they already installed through fullstack-agent, they have these shortcuts already; skip this phase rather than making a second set. + +## Phase 6: Hand it over + +Show them the two commands that matter (`./run.sh`, and "goodbye " to end), where the log lives (`logs/backtalk.log`), and that `backtalk.json` is theirs to tinker with (though they never need to touch it by hand: YOU change it when they ask, in any session, and the voice console changes it live). + +**Tell them how updates work, once.** Jared ships fixes to this repo often, several straight from this community. Any time, in any session, they can say: "pull the latest backtalk and tell me what changed." Their config and identity are never touched by an update. + +**Show them the voice console, once.** Exact phrases, spoken alone, control the session itself: "clear the session", "compact the session", "switch to the deep model" / "back to the fast model", "set effort to low" (or medium, high, max), "usage report", "go hands free" / "push to talk mode" for the microphone, and "stop asking for permission" / "start asking again" for approvals. Words around a phrase make it a normal sentence for the agent instead, so nothing fires by accident. Close with the point of the whole thing: this is the same assistant they type to (same memory, same personality); it just talks now. + +**Tell them the model is deliberate, and remember this yourself.** The voice runs on the fast tier (`claude-sonnet-5`) on purpose: that is most of the difference between a reply in about a second and one that feels broken. Say plainly that the voice loop is not the place to trade speed for depth. If they want a bigger model for hard thinking later, that belongs in their typed session, not here. + +`backtalk.json` ships without a `model` key on purpose, inheriting that default from the code, so there is nothing in the file to hint that the choice was considered. **Do not swap `model` to a deep-work model on their behalf, now or in any future session, even when asked to make the answers smarter, without first telling them what it costs in latency.** Making the voice slow is the fastest way to make someone conclude the whole thing does not work. The sanctioned route is the voice console's "switch to the deep model": the person asks for it themselves, the latency warning gets spoken, and it lasts one session. diff --git a/backtalk/backtalk/__init__.py b/backtalk/backtalk/__init__.py new file mode 100644 index 0000000..01d1f79 --- /dev/null +++ b/backtalk/backtalk/__init__.py @@ -0,0 +1,17 @@ +# backtalk: talk to your Claude Code agent out loud. +# Copyright (C) 2026 Akhil +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU Affero General Public License as published +# by the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Never silently pick; if they shrug, door A. 3. **The vault** (memory piece): Obsidian's own app config (`obsidian.json`) lists every vault on the machine with its path, and reading it beats quizzing a person who may not know what they have (it lists paths only, never note contents). **No `obsidian.json` at all usually means Obsidian isn't installed. Obsidian is REQUIRED, not optional: it is how the person sees and owns their agent's memory, and the memory piece's own wizard installs it (its Part 1, with the person's OK) as part of setup. Never describe it as optional or skippable.** Vaults the registry lists get offered by name ALONGSIDE the always-present option of a brand-new vault just for this system; having a vault never implies wanting to reuse it. Whatever they pick gets pointed at, never moved, and never commented on: list the registry's vaults by name and path, flat, and say nothing about where any of them lives, even one in Documents or a cloud folder (the memory piece's wizard carries that rule and the reason). A fresh vault is created during install at `~/`, directly in the person's home folder next to the agent folder, and the installer says the full path out loud the moment it exists. Two promises the memory piece's wizard keeps, and this conductor never compresses away: the vault gets REGISTERED in `obsidian.json` so the person's first launch of Obsidian opens straight into it (never the welcome screen), and after creating a fresh vault the wizard says the one honest backup line (the memory lives on this one disk; the free options are in its TROUBLESHOOTING). For an adopted vault it says nothing about backup or location. 4. **The microphone** (voice piece): push to talk (hold a key to speak, the default: the mic is closed otherwise, so room audio can never trigger the agent) or hands-free listening (always listening, no button; room audio and videos CAN trigger it, and the talk key still works as the interrupt)? Then, which key. Defaults: push to talk, the home key. They can switch modes any time by voice ("go hands free" / "push to talk mode"). 5. **The voice engine** (voice piece): ask this of EVERYONE, in the interview, with one honest sentence each; it is a real fork, not a power-user extra. Built-in: free, local, works offline, sounds decent but noticeably computer-generated (default `bm_lewis`, the British butler register). ElevenLabs: the natural, human-sounding voice, on their own ElevenLabs account (free tier auditions it; regular talking runs on the paid starter plan). Capture which they want; the account, key, and voice audition happen during that piece's setup, and the voice piece's wizard carries the whole walkthrough. Never pre-answer this one with the default: the choice is the person's, made out loud. diff --git a/start.bat b/start.bat index 2156269..78a87d1 100644 --- a/start.bat +++ b/start.bat @@ -1,6 +1,6 @@ @echo off rem fullstack-agent: give your AI a full stack — memory, voice, face, hands. -rem Copyright (C) 2026 Jared Rhodenizer +rem Copyright (C) 2026 Akhil rem rem This program is free software: you can redistribute it and/or modify rem it under the terms of the GNU Affero General Public License as published @@ -22,8 +22,19 @@ rem close the windows (or this one for the voice) to stop. rem start.bat everything installed rem start.bat voice the voice and the face (no hands) rem start.bat hands the voice and the hands board (no face) +cd /d "%~dp0" -cd /d "%~dp0.." +set "PATH=%USERPROFILE%\.local\bin;%PATH%" + +rem ---- Ensure Ollama is running ----------------------------------------- +powershell -NoProfile -Command "try { (Invoke-WebRequest -Uri 'http://localhost:11434' -UseBasicParsing -TimeoutSec 2).StatusCode; exit 0 } catch { exit 1 }" >nul 2>&1 +if errorlevel 1 ( + echo ollama: not running, starting in background... + start /B "" "%LOCALAPPDATA%\Programs\Ollama\ollama.exe" serve >nul 2>&1 + ping 127.0.0.1 -n 3 >nul +) else ( + echo ollama: online +) if exist "ai-visualizer\" if not "%1"=="hands" ( echo face: starting @@ -31,12 +42,7 @@ if exist "ai-visualizer\" if not "%1"=="hands" ( ) rem Both servers are started through their own run.bat, which finds a -rem working interpreter and holds its window if anything goes wrong.
