Summary

An agent that builds an environment from a prompt records the application with one browser scenario. Until now a
scenario could not carry a value from one step to a later one:

• No ids from responses. After creating an object, the agent could not open, read, edit or delete it by the id the
  application assigned. Agents chose their own ids where the API allows it, or read lists back instead.
• No derived auth headers. An API that takes Basic auth, or a header a frontend builds from a login token, could not
  be sent. Miniflux's agent stopped and asked for an API key.

This PR lets steps save values and later steps send them:

1. A request step saves [{name, json_pointer, secret}] from its JSON response. A click or press step saves from
   the response to the request it triggers, with save_response: {method, path, save}, so a create made through the
   UI yields its id.
2. {saved:name} sends a saved value in a request path (and its query), a goto URL, and a JSON body, where a string that
   is only the placeholder keeps the saved JSON type. Header values and Basic credential parts take
   {"source": "saved", "name"}.
3. A header can send Basic credentials, {"source": "basic_credentials", "parts": [username, password]}, each part a
   literal, declared secret, saved value, cookie or local storage entry.
4. The skill records writes the way the UI does, saving ids from the responses its clicks trigger.
5. The write model serves UI-made creates as faithfully as API-made ones. Recording through the UI let Grafana generate
   folder uids, which exposed three gaps; this PR closes them (below).

Results, agents building seven applications from the same prompts, with main and with this branch:

• Served writes go from 9 to 24, and write tasks from 4/20 to 8/20 and 9/20 with the two models. Miniflux goes from no
  environment to 3/3, and Vikunja from 0/5 to 3/5.
• Rebuilding the branch's own recordings with the write-model fixes changes only Grafana's plans, whose tasks go from
  0/2 to 2/2.
• The fresh Grafana and EspoCRM recordings scored below main's, for reasons in what was recorded (below).

Problem and expected behavior

• A step should save a string or number from a JSON response, by name, and a later step should send it in a path, a
  URL, a JSON body or a header.
• A UI step that submits a form should save from the response to the request it triggers.
• A header should carry Basic credentials built from any value kind.
• A scenario that uses none of this should record and hash as before, and earlier REA versions should read captures that
  use it.

Change and scope

• Schema (browserScenarioValues.ts, browserScenario.ts):
  • save on request steps, save_response on click and press, the saved value source in headers and credential
    parts, basic_credentials with two parts, and {saved:name} (a parsed URL's percent-encoded form included).
  • Validation refuses a saved value no earlier step saves. Other braces, such as {id}, are sent as written.
• Runtime (PlaywrightScenarioRequest.ts, PlaywrightScenarioActions.ts, BrowserScenarioSecrets.ts):
  • A saving request step reads its response text, up to 4,000,000 characters, in the page.
  • A UI step's save_response starts waiting before the step acts and fails the step unless a matching 2xx JSON
    response arrives before its timeout.
  • Saved values keep their JSON type and fill placeholders percent-encoded in paths and URLs.
  • Basic credentials are base64-encoded and redacted, as are parts read from the page. A value saved with
    secret: true is redacted from later records.
• Evidence (BrowserScenarioEvidence.ts): an empty save is left out of the recorded step, so parameters and
  scenario_sha256 are unchanged for scenarios that save nothing.
• Environment build: warns about saved values named like credentials that are not marked secret
  (credential-named-saved-values).
• Skill (version 50):
  • Writes the way the UI does and saves ids instead of guessing them.
  • Falls back to request steps when the UI cannot reach an operation or coverage withholds the UI-shaped write.
  • Its recording example creates through the UI.
• Write model (src/domain/analysisView):
  • A composed string that reads a field besides the generated value a template would rebuild it around wins over
    the template, so Grafana's /dashboards/f/{uid}/{slug(title)} is composed when the uid is generated.
  • Later creates check template fields against their answers, as they check composed ones, so coverage no longer
    serves a template a later create contradicts.
  • A slug learns how the application spells &: ampersand: "and" on a slug rule or composed part, learned from the
    call that shows it. Calls that slugged no & agree with either spelling.
  • Where one text could come from two sources (an id equal to the title's slug), the entities the type holds pick the
    one reading they share. When they cannot, a later create that tells the fields apart lends its composed rule to
    the first create, whose body contract is learned again with it.
• Skill: also asks agents to delete what an earlier attempt created before recording again, since the environment
  holds a leftover as seeded data.
• Docs and spec: the browser scenario contract's saved values section, the environment and web capture references,
  and docs/specs/agent-environments/scenario-saved-values/.

Not included:

• general value transforms or script steps;
• saved values in fill and select_option;
• multi-factor sign-in;
• lists sorted by a field an update changes, which REA keeps in place (pre-existing; seen in Grafana's fresh run).

Contract and boundary impact

• Semantic owner and earliest changed stage: the browser scenario contract (src/domain/browserScenarioValues.ts)
  and its Playwright runtime.
• Contribution scope fit and linked maintainer decision: within the scenario request steps of feat(environment): build agent environments from a prompt #6946. Part of [Design] Project captures into an environment manifest, serve it over streamable HTTP, export agent-environment bundles #4933.
• CLI and MCP/tool-catalog contract:
  • capture_browser_scenario accepts save, save_response, the saved source, basic_credentials and
    {saved:name}.
  • The compact catalog grows by 3,664 bytes, from 1,038,975 on main 2b84efe to 1,042,639, under the 1 MiB frame
    outputSchemaProfile.test.ts measures. A first design with path_params and json_values fields failed that test.
  • save_response.path uses the request path's portable pattern, now shared as START_ORIGIN_PATH.
• Provider, bridge, target-format, or platform compatibility: unchanged.
• Evidence, artifact, provenance, or reconstruction contract:
  • Scenarios that save nothing record the same parameters and scenario_sha256.
  • Captures that save values parse on earlier REA versions.
  • environment-state views may carry ampersand on slug rules and parts; earlier REA versions refuse views that do,
    as the schemas are strict. Earlier views parse unchanged.
• Target selection, authority, upstream behavior, and cleanup details:
  • A UI step with save_response waits for a response on the start origin.
  • Request steps stay same-origin, as before.
• Generated metadata, package, or installation impact: the skill version goes from 49 to 50.

Expected effects:

• Read existing files or captured data.
• Launch or attach to a process.
• Inject instrumentation or run scripts/code.
• Change process memory, registers, files, or configuration.
• Contact network services.
• Recover protected code or work around protections.
• Documentation or usability only; no target interaction.
• Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

Agent-built environments. Claude Code (claude-sonnet-5-5) built each environment from the same prompt with main
ff6d96b (skill 49) and with this branch, on freshly seeded instances. Each bundle's write tasks ran with
fireworks_ai/gpt-oss-120b and fireworks_ai/glm-5p3-flash, each checking the result from the environment's state.

The branch's recordings, rebuilt before and after the write-model fixes (gpt-oss, GLM). Only Grafana's plans change:

Application	Before	After
Miniflux	3/3 3/3	3/3 3/3
Paperless	1/3 2/3	1/3 1/3
Vikunja	1/3 1/3 + 0/2	1/3 1/3 + 0/2
Linkding	0/2 0/2	0/2 0/2
Homebox	0/2 0/2	0/2 0/2
Grafana	0/2 0/2	2/2 2/2
EspoCRM	1/3 1/3	1/3 1/3

Paperless's plans are identical in both builds; its GLM difference is the eval model's.

Fresh recordings, main and the final branch:

Application	Write tasks	Main: served, tasks	Branch: served, tasks
Miniflux	3	no bundle	4, 3/3 3/3
Paperless	3	3, 1/3 1/3; 6, 2/3 2/3	6, 1/3 2/3
Vikunja	3 + 2	1, 0/3 0/3 + 0/2 0/2	3, 1/3 1/3 + 2/2 2/2
Linkding	2	0, 0/2 0/2	3, 0/2 0/2
Homebox	2	1, 0/2 0/2	5, 0/2 0/2
Grafana	2	2, 2/2 2/2; 3, 2/2 2/2	1, 1/2 1/2
EspoCRM	3	2, 1/3 1/3	2, 0/3 0/3

"Served" counts the write tools the final capture serves; tasks are gpt-oss then GLM. Paperless and Grafana were
recorded twice on main.

• Miniflux: main's agent stopped for an API key; with Basic credentials the branch serves category create, rename and
  delete, and every category task passed in all three branch recordings.
• Saved values in use: every branch agent saved ids, with save_response on UI writes.
• How the branch got here. The first branch recording showed that EspoCRM's agent copied the skill's request-step
  example and wrote through the API, which EspoCRM answers in a shape the write model withholds (0/3); the example now
  creates through the UI. The second showed Grafana's UI-made creates served with wrong addresses (0/2); the write-model
  fixes above close that.
• Grafana, fresh: the create is served with the right address and passes. The rename is withheld: Grafana lists
  folders sorted by title, the recording renamed a folder to a title that sorts first, and REA keeps an updated entity
  where it was in a list. Main's REA reads this recording the same way, and would serve its create with the template
  that keeps the first folder's slug. Main's two recordings passed because their titles kept their order.
• EspoCRM, fresh: the recording started with a contact an earlier attempt created and left, so the environment
  holds it as seeded data and the "nothing else changed" checks fail. The skill now asks agents to delete such objects
  before recording again; that was not measured.
• Paperless: the two main runs differ as much as main and the branch do.
• Linkding and Homebox serve more writes, but their create tasks still fail. Linkding's served create requires every
  member its recorded calls sent, so a task sending a URL and a title is refused.
• Census: write plans for 109 captures (the 50 published captures, 29 earlier agent recordings and the 30 above),
  built by main and by this branch: 524 plans and 247 served on each. Three plans differ, all Grafana folder creates,
  whose url the branch composes from the uid and the title's slug.

Real Chrome, a local application with a cookie-session UI and an API that takes only Basic auth:

• An 11-step scenario saved an id from a Save click and opened /items/{saved:item1}.
• It sent Basic credentials from local storage and a secret, and saved a secret token.
• It created a child with {"name": "Child of {saved:item1}", "ref": "{saved:item1}"}, which was sent as
  {"name":"Child of 101","ref":101}.
• The password appears nowhere in the capture, and the token header is recorded redacted.

Tests added:

• schema:
  • a saved value sent before it is saved, in a path, query, goto URL (percent-encoded too), JSON body, header or
    credential part;
  • literal braces sent as written;
  • credential parts from page values, an undeclared secret part, and a wrong part count;
  • save_response paths and an empty save;
• runtime with a fake page:
  • ids sent in a path and a JSON body with their type, and a saved secret redacted;
  • a missing pointer and a non-JSON response;
  • Basic credentials from local storage and a cookie, encoded and redacted;
  • a goto filled percent-encoded;
  • save_response waiting before the click and matching method, origin and {*} segments, and failing without a
    matching or 2xx response;
• Evidence: a scenario that saves nothing records and hashes as before; saved values and placeholders are recorded;
• the credential-named-saved-values warning;
• write model:
  • a generated uid and the title's slug compose a folder's address;
  • the & spelling is learned from a later create, a dropped & stays dropped and a create spelling it otherwise is
    withheld;
  • an id equal to the title's slug is told apart by a later create, or by held entities;
  • a template a later create answers otherwise is withheld;
  • a copied member a composition rebuilds is accepted with any value, and one a template would keep stays fixed.
    Each fails on main.
• Review round (each fails on 812f9ff unless noted):
  • Basic credentials from one-letter secrets and a two-character secret save are redacted;
  • a literal Basic password is refused, an empty one accepted;
  • save_response ignores a request already running when the step began, matches My List against My%20List,
    refuses a response whose received size is over the cap without reading it, and stops listening when the step
    fails (passes on 812f9ff, which never listened);
  • a saving request step stops reading after the chunk that passes the cap;
  • a goto keeps a structured query value that spells a placeholder;
  • a slug field keeps a dropped & an accepted create showed, takes and from held tags, and learns no slug rule
    they contradict; a composed address takes and from held folders;
  • many fields sharing one text leave an address unread (passes on 812f9ff, which reached the same result with
    unbounded work).
• Second review round (each fails on af3d562, the merge of main before it):
  • a saved integer past 2^53 fails the step instead of saving a rounded id;
  • a JSON string spelling %7Bsaved:item%7D needs no save and is sent as written;
  • a held slug neither & spelling gives keeps a create that slugs & from learning a slug rule, and leaves a create
    without & its plain rule.

For evidence-bearing changes:

• Observed, derived, and inferred claims remain distinguishable.
• Artifact identity, source provenance, and failed attempts remain preserved.
• Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Validation performed

Fifth review round at 9f5191ab0 (main ca3fd7ba merged), on macOS with Node v24.22.1:

• 6f6c61613 fixes Greptile's three findings on 22a93fadc: a saved secret is redacted as a URL's query spells it once
  parsed (' as %27); a step's saved-value fills are counted before each is built against a 4,000,000-character budget
  (percent-encoded in a path or goto URL), so repeated references fail the step before it sends; and a create whose
  slug the held & spellings refuse accepts the slugged member only as recorded. Its six tests fail on 22a93fadc;
  9f5191ab0 makes one of them check the plan's body is present first. 3de21ef5d merges main ca3fd7ba.
• typecheck, check:fast, format:check, knip, docs:check, mcp-catalog:check, verify:test-discovery and
  scan:todos: passed. domain + services + adapters: 18,758 passed, with the same two failures as main. Browser
  boundary tests and webArtifactReadOwnership: 1,223 passed, with the two sazWebCapture failures main has.
• Census on main ca3fd7ba and this head: 524 plans and 246 served on each (main's anchorless-clock change withholds
  one Vikunja label update on both), with the same three Grafana creates differing.

Fourth review round at 22a93fadc (main dd7a2da5 merged), on macOS with Node v24.22.1:

• The red CI on 81a275b13 came from main as merged for that run: 662ec2e45 left scripts/verify-apk-signature.mjs
  unformatted (main fixed it in 741f2de75), and webArtifactReadOwnership.test.ts, which passes on this branch,
  failed only in that merge. 723fe02c8 merges main dd7a2da5.
• 22a93fadc decodes a saving response as fatal UTF-8 in both save paths, so a malformed byte fails the step instead of
  saving U+FFFD, and bounds a secret save's spellings from the value before building any (Codex follow-ups). Its four
  tests fail on 723fe02c8.
• typecheck, check:fast, format:check, knip, docs:check, mcp-catalog:check, verify:test-discovery and
  scan:todos: passed. domain + services + adapters: 18,673 passed; the Inspector stat test and
  SetupRegistrationPrewarm's detached-descendant test fail, as they do on main dd7a2da5. Browser boundary tests and
  webArtifactReadOwnership: 1,223 passed; two sazWebCapture tests fail, as they do on main.
• Census on main dd7a2da5 and this head: 524 plans and 247 served on each, with the same three Grafana creates
  differing.

Third review round at 69f38a78b (main a30ffd27 merged), on macOS with Node v24.22.1:

• 7b2e78077 then checks each filled path segment after substitution, so a saved . that the text beside it turns into a
  dot segment fails the step (Greptile's follow-up); its tests fail on 69f38a78b, check:fast passes and src/browser/
  passes 1,043 tests.
• a712f52e2 saves no number that is not finite (1e400), and d0d7c248b lets a later update refine an ambiguous slug
  spelling as creates do (Codex follow-ups); their tests fail on 7b2e78077. check:fast, docs:check and 2,852 browser,
  write-model and environment tests pass, and the 109-capture census stays at 524 plans and 247 served.
• 22ac315c3 keeps an update's word spelling of & for a later name without one and withholds a later create that omits
  a composed or templated field; d39f386d2 caps the saved values a scenario keeps at 4,000,000 characters. Their tests
  fail on d0d7c248b; check:fast, docs:check and 2,859 browser, write-model and environment tests pass, and the census
  is unchanged at 524 plans and 247 served.
• 059322048 reads a saved response only once its decoded size is bounded (gzip/deflate by DEFLATE's maximum expansion;
  br, zstd or an unknown size fail the step) and counts only the spellings a secret save adds; 81a275b13 saves no number
  JSON parsing changes (1e-400, 1.0000000000000001) and spells an update's & as held entities do. Their tests fail on
  the head each thread was reported on; check:fast, docs:check and 2,880 browser, write-model and environment tests
  pass, and the census is unchanged at 524 plans and 247 served.
• Fixes the five Codex findings on 98f18cc5: saved-response reads bounded by the step's deadline and abort signal; the
  4,000,000-character cap kept, with a 12,000,000-byte bound before reading; Basic usernames with a colon refused;
  dot-only saved path segments refused; mixed held & spellings leave no slug rule. It also makes the saved-values
  example a whole scenario, as the product catalog test requires. Each new test fails on 98f18cc52.
• tsc, check:fast, format:check, docs:check, mcp-catalog:check, verify:test-discovery, scan:todos and
  jscpd: passed. knip reports only isToolFamilyId, as main does. domain + services + adapters: 18,201
  passed, with the Inspector stat test failing as on main. Product catalog, output schema profile, MCP schema
  validation, tool schema validity, the environment build and serve CLI, served-writes MCP and analysis-view CLI
  boundaries: 8 files, 75 passed.
• Census on main a30ffd27 and this head: 524 plans and 247 served on each, with the same three Grafana creates
  differing; none of this round's fixes changes a plan.

Earlier rounds:

Run on macOS with Node v24.22.1 at e42362c (main 2b84efe). Agent recordings ran on Ubuntu 24.04 VMs with snap
Chromium.

• npm run typecheck, lint:built, format:check, metadata:check, verify:architecture-guards, knip:production,
  lint:typed, docs:check, mcp-catalog:check, verify:test-discovery, scan:todos and jscpd: passed. knip
  reports one unused export, isToolFamilyId in src/contracts/toolFamilies.ts, which this branch does not touch and
  main 2b84efe reports too.
• npx vitest run --project domain --project services --project adapters: 18,261 passed and 1 failed, "stops Inspector
  target authorization after the current stat settles", which fails the same way on main in this environment.
• npm run test:focused -- the browser scenario CLI and MCP boundaries, scenario input diagnostics, scenario
  cancellation and cleanup, the analysis-view CLI and MCP boundaries, the environment build, export and serve CLI
  boundaries, the environment serve, served-writes and bundle MCP boundaries, tool schema validity, MCP schema
  validation, and output schema constraints and profile: 17 files, 128 passed.
• Census on main 2b84efe and this branch: 524 plans and 247 served on each, with the same three Grafana creates
  differing.
• Scenarios that save nothing: identical parameters and scenario_sha256 on main and on this branch.
• Main reads the real-Chrome capture: environment-build --dry-run gives the same manifest, state, coverage and file plan
  on both.
• After the first review round, the real-Chrome scenario, with its save_response path written as /ui/{*}, completed
  all 12 steps with no password or raw token recorded.

Compatibility, safety, and release

• Breaking changes or migration steps: none for callers.
• Real Hopper/Ghidra, browser, or OS coverage: Google Chrome on macOS for the local check; snap Chromium on Ubuntu
  24.04 for the agent recordings.
• Package or release metadata impact: skill version 50.
• Security, privacy, process, or containment review:
  • Saved values are kept in memory for the scenario only.
  • A value saved with secret: true, Basic credentials, and parts read from the page are redacted from later records.
  • The response a secret was saved from may keep it, since the recorder reads bodies on their own schedule; the
    contract says so.
  • The build warns about credential-named saved values not marked secret.

Summary

Adds saved response values and Basic credentials to browser scenarios, then uses those values in later requests and navigation.

• Browser scenarios save response values and reuse them in later steps.
• Write plans rebuild addresses from the values each create sends.
• Slug rules record when an ampersand becomes the word “and.”

earakely-scale documents two intentional limits: a response that supplies a saved secret may retain it, and earlier REA versions reject environment views containing the new ampersand field.

Review was source-only; no tests were run. Supersession status could not be checked because authenticated GitHub access was unavailable.

Second review round: e42362c fixes the three Codex findings on 212063f (replies in each thread), after merging main 2b84efe. The merge resolved one conflict with the JSON-field ownership refactor; this branch's new field reads now use ownMember too. save_response.path now shares the request path's portable pattern (START_ORIGIN_PATH), which main's new pattern test requires.

Verified at e42362c on Node 24.22.1, with dependencies reinstalled for main's zod 4.6.6:

• typecheck, lint, format, metadata, architecture guards, production knip, typed lint, docs, catalog, test discovery, todo scan and jscpd: passed. knip reports one unused export in src/contracts/toolFamilies.ts; this branch does not touch it and main 2b84efe reports it too.
• npx vitest run --project domain --project services --project adapters: 18,261 passed; 1 failed, the Inspector cancellation test that fails on main here too.
• 17 browser, environment and analysis-view boundary files: 128 passed.
• Census of 109 recorded captures on main and this branch: 524 plans and 247 served on each; only the three Grafana folder creates differ.
• Compact catalog: 1,038,975 bytes on main, 1,042,639 on this branch.
• Real-Chrome scenario: 12 of 12 steps, the saved id sent as a JSON number, no password or raw token recorded.

Third review round: 69f38a78b fixes the five Codex findings on 98f18cc52, after merging main a30ffd27. Each thread has a reply, and all threads are resolved:

• Saved-response reads race the step's deadline and abort signal.
• The character cap gets a 12,000,000-byte bound before reading.
• A Basic username with a colon fails the step.
• A saved ./.. filling a whole path segment fails the step.
• Mixed held & spellings leave no slug rule.

The saved-values example in the browser scenario contract is now a whole scenario, which fixes CI's productCatalog failure. Each new test fails on 98f18cc52.

Verified at 69f38a78b:

• Static gates pass. knip's one unused export, isToolFamilyId, is reported by main too.
• domain + services + adapters: 18,201 passed, plus the Inspector stat failure that main also shows locally.
• 8 focused boundary files: 75 passed.
• The 109-capture census is unchanged from main: 524 plans and 247 served, with the same three Grafana creates differing.

Tie saved responses to the dispatched UI action

When Playwright is still waiting for locator actionability, a periodic or background request with the same method and path can begin after this listener is installed but before the click or press is dispatched; watch adds it and waitForResponse can settle on its response first. The step then saves an unrelated ID under the caller's name, so a later request can edit or delete the wrong object. Tie candidate request identity to the actual input dispatch, or reject ambiguous matches, rather than treating every post-listener request as triggered by the action.

Budget derived Basic credentials before retaining them

Fresh evidence beyond the aggregate saved-value fix is that one request can declare many Basic headers which share a large declared-secret username and use distinct short saved passwords, and every header is resolved before dispatch. This call permanently retains each distinct Base64 credential and recompiles all redaction patterns, while SavedFill charges only the short saved parts and MAX_RETAINED_SAVED_CHARACTERS does not charge these derived values, so a single admitted scenario can exhaust memory before fetch; preflight and account the encoded credential spellings in a retained-state budget.

Preserve negative zero in saved numeric values

Fresh evidence after the numeric round-trip fixes is that a response number -0 reaches this branch with no significant digits, so decimalOf returns "0" and accepts it as equal to String(value). JSON.parse had preserved negative zero, but later path/header substitution and JSON.stringify emit positive 0, which changes the selected value for consumers that distinguish signed zero; reject -0 or retain its source representation.

Reject array metadata in saved JSON pointers

When a response is {"ids":["a","b"]} and a save uses /ids/length, pointerValue skips the numeric-index branch and then Object.hasOwn reads the JavaScript array's own length, so this new save path stores 2 even though the JSON contains no member at that pointer. A later write can therefore send computed runtime metadata as if it were response evidence; array traversal should reject every non-index token.

Thank you for the substantial saved-values work and the detailed review follow-ups. #7267 builds on this proposal and credits its original work, but says it compared changes through an earlier head; this PR has since moved. Could the contributors coordinate on one review path and check the later fixes here against #7267 before consolidating? I am leaving both open while that comparison is made.

[earakely-scale]

Thanks — compared #7162 at 9f5191ab against main after #7267: all 55 of #7162's write-model tests pass on main, and its skill text is there. One behaviour #7267 left out: saving from a compressed or cached response (#7162 read gzip/deflate within a bound from the received size); Grafana gzips its folder creates, which recordings save ids from. I'll propose that separately. Closing this in favour of #7267.
