Subject: [PATCH 1/8] Add per-member skill learning control and fix skill
 provenance (#1145)

Generating skills deleted every pending skill in its scope, including
Agent Skills Finder suggestions awaiting approval and manual pending ones.
Skills now record their source (manual, llm, finder) and generation only
replaces its own pending llm suggestions. activeSkillsText also filters by
organization, and the skill endpoints validate their bodies with DTOs.

Intent capture was one switch for the whole workspace. Admins can now set
each member to inherit, on or off (also in bulk, optionally erasing the
intents already captured), and members can opt themselves out. Only
contributing callers get the _intent parameter; callers without a member
identity never contribute. Changes are logged as LEARNING_CHANGED.

+### Who contributes to skill learning
+
+Whether a user's requests are captured is decided per user and per workspace:
+
+- **Workspace default:** the *Intent capture* switch (Settings → Organization →
+  Features). Users set to *Default* follow it.
+- **Per user (admins):** Settings → Users → *Skill learning* sets a user to
+  *Default*, *On* or *Off*. Select several users to change them at once; when
+  turning learning off you can also erase the requests already captured from
+  them.
+- **Opt-out (each user):** Settings → Profile → *Skill learning*. A user can
+  always opt out and erase their own captured requests. Removing the opt-out
+  does not turn learning on: the admin's setting applies again.
+
+A caller with no user identity (an instance-level static API key or bearer, a
+client-credentials token) never contributes. Every change is recorded in the
+security event log as `LEARNING_CHANGED`. Settings belong to the workspace
+membership, so the same person can have different settings in two workspaces.

Subject: [PATCH 2/8] Serve workspace skills on demand with procedures and
 versions (#1148)

Every applied skill was pasted into the initialize instructions, a skill
could only hold a 2,000-character rule, and edits overwrote it.

- skills_list / skill_get on /mcp/:serverId when the caller sees an
  applied skill, scoped to the server's organization and the caller's
  visible connectors; each skill is also offered as an MCP prompt.
- Per-server skills_delivery: auto (full text up to 6,000 characters,
  else an index), inline or index. The migration pins servers already
  above the threshold to inline so nothing changes until an admin opts in.
- Optional body (markdown, up to 20,000 characters) served by skill_get
  only; the Skills Finder can file one.
- Edits keep the previous content in kg_skill_versions; skill_get and
  prompts count uses. Consolidate leaves skills with a procedure alone.
- AI Skills page shows procedure, version, usage and history; the MCP
  server page gets the delivery setting.

 Cloud and self-hosted behave the same.
 
-### Skills are instructions, not extra tools
-
-> **Important:** applied skills do **not** add tool calls to your MCP surface.
-> All applied skills for a server (its own server-scoped skills plus the
-> connector-scoped ones for its connectors) are concatenated into a single
-> `## Workspace skills` block inside the server's `instructions`. The agent reads
-> them as guidance — the tool list is unchanged.
+### How skills reach the AI client
+
+A server's applied skills (its own server-scoped skills plus the
+connector-scoped ones of the connectors the caller can use) reach the client in
+two ways:
+
+- **In the instructions** sent on connect, as a `## Workspace skills` block.
+  Each MCP server chooses how (MCP server page → *Workspace skills on connect*):
+  - **Automatic** (default): the full text while it fits in about 6,000
+    characters, otherwise an index of ids, titles and *when to use*.
+  - **Always the full text.**
+  - **Always a list** (the index).
+- **On demand**, with two built-in tools that appear on `/mcp/<serverId>` when
+  the caller can see at least one applied skill:
+  - `skills_list(query?)` lists or searches the skills;
+  - `skill_get(skill)` returns one skill in full, by id or exact title.
+
+  Both read the current version at call time and only return skills the caller
+  can see on that server.
+
+Each skill is also offered as an **MCP prompt**, so clients with a prompt
+picker (slash commands) can start one by hand.
+
+A skill has a short **instruction** (up to 2,000 characters) and an optional
+**procedure** (markdown, up to 20,000 characters) for the full steps of a
+workflow. The procedure is never pasted into the instructions: the full-text
+mode mentions it with its id, and `skill_get` returns it. The Agent Skills
+Finder's `skills_save_to_workspace` can file a procedure too.
+
+The shared `/mcp` endpoint keeps its fixed toolset: its workspace guide
+(`anythingmcp_get_workspace_guide`) returns the skills as text, procedures
+included.
+
+**Versions and usage.** Editing a skill's title, *when to use*, instruction or
+procedure keeps the previous content as a version (see *History* on the skill)
+and increments its version number. Each `skill_get` or prompt use is counted, so
+the Skills page shows how often a skill was opened and when. Consolidate with
+AI leaves skills that have a procedure untouched.
 
 Because composition is dynamic, editing or deleting a skill takes effect on the
-next request — there's no blob to clean up.
-
-> **Scaling note.** Applied skills are concatenated verbatim into the server's
-> instruction block, so with many active skills that block grows and consumes
-> context on every session. Keep the applied set tight: scope skills to the
-> right server/connector, dismiss duplicates, and use **Consolidate with AI** to
-> merge overlapping active skills into fewer rules.

Subject: [PATCH 3/8] Add workspace memory for AI clients (Enterprise) (#1151)

AI clients can save facts, preferences and notes and find them again in
any client connected to a server of the workspace: personal memory per
member (readable only by that member) and a company memory.

- memory_items with a generated tsvector ('simple') and GIN index;
  organization_members.memory_access (inherit, none, read, personal,
  contribute) with a workspace default.
- memory_search / memory_save / memory_forget on /mcp/:serverId only,
  offered by the caller's level; results are labelled as data, not
  instructions. Company memory from AI clients waits for approval unless
  the workspace switch is set to automatic.
- Secrets are refused; size limits per item, member and workspace.
  Admins can erase a member's personal memory without reading it;
  removing a membership deletes it. Access, settings and erasures are
  logged as security events.
- Licence gate in ee/licensing (EditionService.hasMemory): an active
  Enterprise licence of the workspace (Cloud) or instance (self-hosted);
  not the trial or transition period. The code itself is AGPL.
- Memory page (my memory, company memory, review, settings), Memory
  column and bulk actions on Settings > Users, docs/memory.md.

+# Workspace memory
+
+Workspace memory lets AI clients save facts, preferences and notes and find
+them again later, in any client connected to an MCP server of the workspace
+(Claude, ChatGPT, Copilot, Cursor and others). It is available with an
+**Enterprise licence**, on AnythingMCP Cloud and on self-hosted instances.
+
+- **My memory** (personal): one user's items, for example "answer me in
+  Italian, numbers as tables". Only that user can read them, admins included.
+- **Company memory** (organization): knowledge for everyone, for example
+  "STAMMKUNDE means a customer with a framework agreement".
+
+Memory is served to AI clients as information written by people, never as
+instructions. Rules and procedures the AI must follow belong in
+[AI skills](knowledge-graph.md#ai-skills).
+
+## MCP tools
+
+The tools are offered on per-server endpoints (`/mcp/<serverId>`) only, and
+only those the user's access level allows. The shared `/mcp` endpoint is
+unchanged.
+
+| Tool | Offered from | What it does |
+|---|---|---|
+| `memory_search(query?, scope?, limit?)` | Read | Full-text search over the company memory and, from Personal up, the user's own items. An empty query returns the most recent items. |
+| `memory_save(content, kind?, scope?, tags?)` | Personal | Saves a fact, preference or note. `scope: "organization"` is offered from Contribute. |
+| `memory_forget(id)` | Personal | Deletes one of the user's own personal items. Company memory is changed in the dashboard only. |
+
+## Access per user
+
+Each user has one of these levels in a workspace (Settings → Users → *Memory*,
+one by one or for several selected users):
+
+| Level | Company memory | My memory | Propose to company memory |
+|---|---|---|---|
+| No access | – | – | – |
+| Read | read | – | – |
+| Personal | read | read and write | – |
+| Contribute | read | read and write | yes |
+| Default | the workspace default (Memory page → *Workspace settings*, initially Personal) | | |
+
+Users without a user identity (instance-level static credentials,
+client-credentials tokens) and deactivated users have no access.
+
+## Company memory from AI clients
+
+Memory page → *Workspace settings* → *Company memory from AI clients*:
+
+- **Needs approval** (default): what an AI client proposes waits under
+  *To review* until an admin or editor approves or rejects it.
+- **Saved automatically**: it is active right away.
+
+Either way, each item records who saved it and from which client, and admins
+and editors can edit or delete company memory on the Memory page. They can
+also add to it directly.
+
+## Privacy and safety
+
+- Content that looks like a password, token or key is refused.
+- An item holds up to 2,000 characters and 10 tags. A user keeps up to 1,000
+  personal items per workspace, a workspace up to 20,000 items.
+- Admins can erase a user's personal memory without reading it (Settings →
+  Users → select → *Erase personal memory*). Removing a user from a workspace
+  deletes their personal memory there; deleting the account deletes all of it.
+- Every change of access or settings and every erasure is recorded in the
+  security event log (`MEMORY_ACCESS_CHANGED`, `MEMORY_SETTINGS_CHANGED`,
+  `MEMORY_ERASED`).
+- Without the licence (or after it expires) the tools and the page are not
+  available; stored memory is kept, and admins can still erase personal memory.
+
+## Search
+
+Search uses PostgreSQL full text with the `simple` configuration (no stemming,
+so German, Italian and English behave alike), ranked by relevance, and falls
+back to a substring match for partial words and codes. No extra service or
+embedding provider is needed.

Subject: [PATCH 4/8] Add folders for skills and company memory, with role
 limits (#1153)

One folder tree per workspace, shared by skills and the company memory,
so a topic holds both its procedures and its facts.

- knowledge_folders (parent, name, description, role_ids) and folder_id
  on skills and memory items; up to 4 levels, unique sibling names.
  Deleting a folder moves its subfolders and items to the parent.
- MCP: skills_list(folder) lists a folder and its subfolders; the skill
  index is grouped by folder and, when too large, lists the top-level
  folders for skills_list. memory_search(folder) and memory_save(folder)
  for company items; AI clients never create folders.
- Role limits (Enterprise, set by admins): a folder limited to custom
  roles is hidden with its subtree from everyone else on every path
  (instructions, skills_list/skill_get, prompts, memory_search,
  kg_how_to_obtain, dashboard). Admins see everything. Limits keep
  applying without the licence. Moves and deletes never widen access:
  only an admin can move content out of a limited folder, a limited
  folder with items cannot be deleted, and its subfolders inherit the
  limit. Changes are logged as KNOWLEDGE_FOLDER_ACCESS_CHANGED.
- EditionService.hasEnterprise / assertEnterprise generalise the memory
  gate for both features.
- Folder tree with edit, move and role editor on the AI Skills and
  Memory pages; docs updated.

+## Folders
+
+Company memory and skills share one folder tree per workspace, so a topic
+such as "Sales / Quotes" holds both the procedures (skills) and the facts
+(memory). Folders are available in every edition.
+
+- Admins and editors create, rename, describe, move and delete folders from
+  the left column of the Memory page (Company memory tab) or the AI Skills
+  page. Folders go up to 4 levels deep. Deleting a folder moves its subfolders
+  and items to its parent; nothing is deleted.
+- Personal memory has no folders; use tags.
+- `memory_search(folder: "Sales")` searches a folder and its subfolders.
+  `memory_save` can file a company item in an existing folder. AI clients
+  never create folders. Results show each item's folder.
+
+### Limiting folders to roles (Enterprise)
+
+An admin can limit a folder to one or more custom roles (Settings → Roles,
+including roles synced from the identity provider): edit the folder → *Visible
+to*. The limit applies to the folder and everything below it, for skills and
+memory alike, on every path: instructions, `skills_list` / `skill_get`,
+prompts, `memory_search`, `kg_how_to_obtain` and the dashboard. Workspace
+admins see every folder. For everyone else a limited folder does not exist.
+
+Setting limits needs an Enterprise licence. Limits already set keep applying
+without it, so access never widens on its own. Every change is logged as
+`KNOWLEDGE_FOLDER_ACCESS_CHANGED`.
