ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This XXL PR introduces a broad Skills and agent-instructions workflow with new RPC/MCP surfaces, provider configuration changes, and filesystem operations that can move, merge, delete, or symlink user and project files. It also modifies authorization and adds diagnostic suppressions, so the scope and risk require human review. Not approved because:

📝 Walkthrough
Merge Risk: 🟡 Moderate · up to The Skills and Instructions page is mostly ready. Project instruction reads are now limited to registered projects, and file encoding is preserved. One open concern is the Codex shadow-home setup. The page and Codex may read different settings files, so a skill can show as on or off when Codex treats it the opposite way. The user guide also misses one Claude rule. Resolve these before merging or accept them knowingly. Security Architecture Review

Add `server.listSkills` and `server.getSkill`, which read the skill folders of the enabled provider instances straight from disk: no agent is asked to rescan, and nothing is written. An agent loads one skill per name, the first it finds in its folders, so the catalog walks each instance's folders in that order and a shadowed copy is `none` for that instance. Copies of a name that differ, in one scope or across scopes, are reported. A SKILL.md header that Claude Code can't parse marks the skill as skipped by Claude, using Claude's own header parser. Folders follow each instance's config: a Claude instance's config directory or `CLAUDE_CONFIG_DIR`, `CODEX_HOME`, and `GROK_HOME`. Folders that exist but can't be read are returned with the list. Descriptions are cut at 160 characters with a trailing "…". A SKILL.md that is a link out of the skill's folder isn't read, and the file walk is bounded in files, folders and entries per folder. The Claude, Cursor and Antigravity scanners now read their folders from the same table, and tests pin each scanner's folders and their order. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Settings → Skills lists the skills in This project and Global, and shows which of your enabled agents can use each one. Search and a Needs attention filter surface skills an agent doesn't use, copies that conflict, and skills Claude can't read. Opening a skill shows its description, which agents use it, any scripts it includes, and its files in a read-only viewer, with Copy path in a menu. Escape in a skill returns to the list. The agents are the enabled provider instances, named and drawn like everywhere else in the app, so two instances of one driver are told apart.

Listing skills and reading a skill return folder listings and SKILL.md text, which are file contents. They took the orchestration read scope that thread readers hold, where the other file reads (project files, folder listings, folder browsing) take the filesystem read scope. Use that one for both. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The skill list and a single skill took any absolute folder as the project and scanned the skill folders under it, so a client could have the server read the folders of any path on the machine. A given folder must now be the workspace root of a project the environment knows, the same check the skill writes make, or the read is refused with `projectNotRegistered`. Global reads, which have no folder, are unchanged. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…ed by Claude The list reported Claude as reaching a skill that Claude's own `skillOverrides` turn off, though the `$` picker already greys out the same skill. The list now reads the overrides the way the picker does (user, project, project-local, then managed policy) and shows such a skill as not used by Claude, the same as for any other copy Claude doesn't load. The override names the skill by folder name, so it applies to every copy of the name. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
When the settings scope's environment was offline, the Skills page fell back to the primary environment (or the first one) and showed its skills as the picked project's, and could send that checkout's folder to the wrong server. The page now stays on the scope's own environment and says it is offline; only a scope that names no environment falls back to the primary one. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The refresh button's request set state after its page was left, where the first load already drops a result that arrives late. Guard it the same way. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A skill reaches an agent through a link in the agent's own folder. Add enable, disable and remove for that: a link is made with a bare create and removed only when it is still the link that was inspected, so a real folder or another skill's link is never replaced or deleted. Every write re-reads the folders, refuses a skill whose home moved since the list was read, and needs a registered project folder for project skills. Results are one outcome per skill, so one bad skill doesn't stop a bulk request. The three RPCs need the operate scope. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The "Used by" chips in a skill become switches, rows get checkboxes with a bulk bar (turn on for all agents, turn off for one agent, remove), and a row in Needs attention offers a one-click turn on. Turning off asks first only when another agent loses the skill too, and remove always asks. After every change the page reads the list from the server again instead of predicting it.

…skill changes Settings → Skills can only turn skills on or off for an agent. Moving a skill between a project and Global, or deleting it, meant doing it by hand, and the chat composer's `$` picker could lag behind any change. `server.moveSkills` moves a skill's folder to the other scope's shared folder: one rename on one filesystem; across filesystems a copy next to the destination under a hidden name, checked against the original, then renamed into place before the original goes. It never merges into or replaces a skill with the same name, and a failed copy leaves no half-made skill. The agents' old links are removed and recreated at the new scope with the same rules as turning a skill on. `server.deleteSkills` deletes a skill's own folder and the links to it. Both only act on a folder that sits in an agent's skill folder itself, never a synced library behind a link, and both need Operate scope. After any write that changed what an agent can use, the agents involved have their composer skill list refreshed in the background, once, and nothing is refreshed when nothing was written. The skill list says which skills have a real folder, so the page can offer a move only where it works. `server.skillsTracked` says which project skills git tracks, with one `git ls-files` for the skills in a confirmation, so the page promises an undo with git only where there is one. Listing still spawns nothing. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Adds Move to Global, Move to this project and Delete to a skill's menu and to the bar over ticked skills. Each asks first and names what goes; Delete says it can't be undone, and Remove from agents says the original isn't deleted. A confirmation says "You can undo this with git" once the server has said git tracks the folder, and not when that check fails. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

…ools Adds t3_skill_list, t3_skill_get, t3_skill_enable and t3_skill_disable. Reads need any orchestration credential; changes need a full-access caller, like project changes. Removing, deleting and moving skills stay out of reach of agents. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…ills in projects The skill contracts gain what the next steps build on: - An agent can be `off` for a skill: it can see the skill, but its own settings switch it off. An agent T3 Code can't switch for a skill is `fixed`, so a client can disable that switch. - A skill can carry `source` (`owner/repo` from the installer's record, for grouping) and `projects` (the projects a Global skill is used in, when that isn't all of them). - `server.placeSkills` replaces `server.moveSkills`. It puts skills in one project, in Global, or in Global but used only in some projects. Every project named must be registered. - `server.removeSkills` is gone: turning a skill off for every agent covers it, so the page no longer offers "Remove from agents". - A skill can be left as it is with `setElsewhere`: a project or organization setting decides it, so the agent's switch can't. Enable, disable, place and delete are guarded client mutations, and the permission tests cover them and the reads that stay open. The server still moves skills between a project and Global as before; placing in only some projects is refused until it is built. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…permissions on atomic writes The picker's reader of Claude Code's skillOverrides now exposes the settings files it merges one layer at a time, so the Skills page can write the right layer and tell which one decides a skill. Skill headers also report their declared name. Atomic writes can keep a file's permissions, for settings files that hold credentials. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Buttons sit on the chips' line in the expanded panel, and group rows hide their agent icons below the sm breakpoint so the source fits. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…k tracking's folder Turning skills on or off, moving them and deleting them make and remove links, write the agents' own settings files and move and delete skill folders, but took the orchestration operate scope. They now take the filesystem write scope, as writing a project file does, and the Skills page's switches follow it, since they read the same grant. The git tracking check ran `git ls-files` in any absolute folder it was given. It now takes the filesystem read scope, and the skill catalog's lookup that it goes through refuses a folder that isn't a registered project's workspace root, like the list and a single skill do. The skills MCP tools keep their own gate: reads are open to any caller, and changes need a live full-access thread or a client approved above read-only, which is stricter than the scope. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
An instance with a shadow home runs Codex there, so the app-server writes the skill setting to the shadow home's config.toml, but the switch was read back from the shared home's. When the shared config.toml didn't exist as the instance started, the shadow home keeps a file of its own, so the write landed there and the read-back reported `failed`. The catalog now gives the switches the home Codex runs in, which the page's own "is Codex switched off" check reads too. The skill folders still follow the instance's home, and the shadow home's links are untouched. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…t manager The Git driver imported the skills domain and linked a project's library skills into every new worktree it made. The worktree flows (the Git action, thread launch, turn start, the MCP tool and a pull request thread) all reach the driver through GitManager, which already owns worktree policy (the folder, submodules, the setup script), so the link step lives there now and the driver is git only again. The driver files are back to what they are upstream. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…n folder A worktree is a checkout of the whole repository, so when a project is a folder inside its repository (a monorepo's apps/site) its folder in the worktree is under the worktree's root. The links a new worktree gets, and the ones removed from a project's worktrees when it stops using the skill, were joined onto the worktree's root, so they landed in or were looked for in the wrong folder. Both now go through the project's folder in the repository, as `git rev-parse --show-prefix` gives it. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…screen The Skills guide described the sparkle and the icons beside a switch, clicking a row, a bar at the bottom, badges and the buttons on a row. Keep what the switches do and where they apply, and drop the rest. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…f dying The manager looked up the project with `orDie`, so a folder that no longer exists (which can't be normalized) was a defect instead of the `projectNotRegistered` refusal every other unknown folder gets. The manager now asks the catalog, which holds the rule for what a project is: a missing folder is refused, and only a failure of the lookup itself is a defect. The placement's `refuse` helper that only built its error is gone, per the service conventions. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
`restoreLibraryLinks` resolved a project link's target against the link's folder to see if it leads into the library, then wrote the raw target into the worktree. A relative target leads somewhere else from a worktree at another depth. The new link now names the library skill's absolute path. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
`editExcludeBlock` documented that a block with a start marker and no end is left alone, but it appended a second complete block. A later edit then paired the dangling start with the new end and could not remove T3 Code's markers. The text is now returned unchanged, so the exclude file isn't written and the link stays visible to git; callers already treat an unchanged file as done.

Adds the schemas and ten RPCs for listing, reading, editing and controlling who reads AGENTS.md and CLAUDE.md files. Reads need the read scope and everything else the operate scope, like the skills RPCs. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Adds a data-only table of the AGENTS.md / CLAUDE.md family that Claude, Codex, OpenCode, Pi, Cursor, Grok and Antigravity read at project, home and managed level, with sources. Also adds pure helpers for Claude's "Project instructions" setting, the AGENTS.md import line, and the Claude Code version check. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…ng check Skills and the coming instruction files need the same two things: where an agent keeps its config (Claude, Codex and Grok each have a setting or variable that moves it) and which project files git tracks. Both move out of the skills code unchanged so instructions reuse them. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Lists the AGENTS.md and CLAUDE.md files in a project and in the user's home, says which agent reads each (following each agent's own rules: Claude's Project instructions setting, version and CLAUDE files, Pi and OpenCode CLAUDE.md fallbacks, Codex's override file), and lets a client read, edit, delete and share them. Edits go to the real file behind any link, only when the file is unchanged since it was read. One shared file links into each agent's home (Claude imports it), an agent's own text is added to it before the agent is linked, and Claude's setting is written without touching the rest of settings.json. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…rough MCP tools Adds t3_instructions_list, t3_instructions_get, t3_instructions_enable and t3_instructions_disable, like the skills tools. Enabling and disabling only affect the shared file for all projects and need full access; editing and deleting stay with the user. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Declares the ten instruction commands (list, read, write, enable, disable, set the Claude setting, share, adopt, delete, tracked) the same way the skills commands are, so the web client can call them. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…kdown and agent chip The Instructions section needs the same pieces the skill page already has: Escape to go back, copying a path, the safe Markdown renderer, the agent chip with its switch, and the confirm dialog for any plan with a confirmation. They move out of the skill components unchanged, so skills behave as before. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
An Instructions section at the top of the Skills page lists the files agents read: This project, Just you (CLAUDE.local.md), files in subfolders, Global, each agent's own, and the organization's. Each row shows the agents that use it and, when something is off, says so with a one-click fix (Turn on for Claude, Use Global instead, Share with all agents). Global opens in place into one switch per agent. Claude reads AGENTS.md has its own choice. A file opens in an editor that saves as you type, previews Markdown, and asks before overwriting a file that changed on disk. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

The Edit button now shares the chips' line in the expanded Global row, and the confirmations and toast say "your Global instructions" instead of a bare "Global". Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…DE.md into AGENTS.md
The Instructions list mixed made-up names ("This project", "Just you", "Claude's own notes")
with gray explanations, and gave an agent's own Global file a permanent row. Rows are now file
names under Project and Global headings, and the only second line is a problem with its fix.
- CLAUDE.local.md sits under Project. Files no enabled agent reads, such as CLAUDE.md with Claude
off, aren't listed.
- An agent with its own Global AGENTS.md shows as a line on Global AGENTS.md, with Use Global
instead, rather than as its own row.
- A project's CLAUDE.md can be moved to AGENTS.md, or merged into an AGENTS.md that already
exists: its text goes at the end and CLAUDE.md is deleted. When Claude would still skip
AGENTS.md afterwards, the same confirmation turns AGENTS.md on for Claude.
- A CLAUDE.md that only imports AGENTS.md, or is a link to it, gets no row.

…copes Listing, reading and the git tracking check took the orchestration read scope, and writing, linking, sharing, adopting and deleting an instruction file took the operate scope, though they read and change files on the machine. They now take the filesystem read and write scopes that project file reads and writes take, and the Instructions page's controls follow the write grant through the same command permissions. The instruction MCP tools keep their own gate, like the skill tools: reads are open to any caller, and turning agents on or off needs a live full-access thread or a client above read-only. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
… folder Only a write checked that the folder was a project: a read took any absolute folder, so with `cwd: "/"` an id like `project:nested:home/me/notes/AGENTS.md` read any AGENTS.md or CLAUDE.md on the machine. The catalog now refuses a folder that isn't a registered project's workspace root, in `resolve`, `list` and so `read`, before it reads anything, and the git tracking check refuses it too. The home files, which have no folder, are read as before. The manager's own check is gone, since every write resolves its id through the catalog. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The reader decoded files with a decoder that drops a leading byte order mark, so saving a file from the editor or adding an import line wrote it back without the mark, and the mark handling in `addAgentsMdImport` and `removeAgentsMdImport` never had a mark to handle. The mark now stays the first character of the text, so the revision (a hash of the bytes) still names what is on disk and the import line goes after it. `parseSettingsJson` skips a mark in front of a settings.json, which it never saw before. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
… failed The instruction catalog and manager each had a `refuse` helper that only built an `InstructionError`; the errors are built where they happen now. The manager's file guard turned a refused permission into an `InstructionError` with no cause, and every other platform failure (a full disk, a read-only mount, a file that went away) into a defect, so the page showed a generic "couldn't change" for one and the server logged a crash for the other. Both now carry the platform error as their `cause`, and the other failures are `writeFailed`, which the page words as "Couldn't change that file." A failed link is still `linkFailed`.

…on screen Drop the clicks and the row and button narration from the Instructions and Needs attention sections of the Skills guide, and note beside the shared config home lookup that a Codex instance's settings are read from its shadow home. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The guide named `CLAUDE.md` and `CLAUDE.local.md`; Claude also skips `AGENTS.md` for a top-folder `.claude/CLAUDE.md`, which the Instructions page counts the same way. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Problem
Besides skills, every agent reads instruction files, and each one reads a different set. Claude reads
CLAUDE.md,CLAUDE.local.mdand~/.claude/CLAUDE.md, and by default skips a project'sAGENTS.mdwhen aCLAUDE.mdis there. Codex readsAGENTS.mdand~/.codex/AGENTS.md. OpenCode reads~/.config/opencode/AGENTS.md. A user who moves between agents can't tell which instructions each agent actually gets. A team'sCLAUDE.mdis invisible to Codex, and global instructions drift into one copy per agent.Change
An Instructions section at the top of the Skills page, under Project and Global headings.
Server (
InstructionCatalog,InstructionManager,apps/server/src/instructions/)AgentInstructionFiles.ts): project, home and managed files, selection rules and fallbacks, with the agent's docs or source cited for each.~/.agents/AGENTS.mdshared by every agent. An agent joins through a link at its own home file, or for Claude an@import line. Nothing is replaced: an agent with its own file offers Use Global instead, which adds that file's text to Global first.CLAUDE.mdcan be moved toAGENTS.md, or merged into an existingAGENTS.md, which deletesCLAUDE.mdafter its text is written. If Claude would still skipAGENTS.mdafterwards, the same confirmation turns AGENTS.md on for Claude. ACLAUDE.mdthat only imports or linksAGENTS.mdisn't listed.CLAUDE.md, alongside anyCLAUDE.md, or never.CLAUDE.local.mdis kept out of git, and confirmations say when git can undo a change.Web. Rows are file names, with a second line only for a problem and a button for its fix. Files no enabled agent reads, such as
CLAUDE.mdwith Claude off, aren't listed. Opening a file shows who reads it and an editor that saves as you type and asks before overwriting changes made on disk.RPCs: the 10 instruction RPCs are their own
WsInstructionRpcGroup, merged intoWsRpcGroup, so the wire contract is unchanged. The server registers their handlers in a secondtoLayer, because onetoLayerover every RPC is close to the compiler's instantiation limit. Past that limit,tsgoquietly turns the server's layer types intoany.Agents: MCP tools
t3_instructions_list,t3_instructions_get,t3_instructions_enableandt3_instructions_disable. Agents edit the files themselves, and the Claude choice stays the user's.Scopes: reading instruction files requires
filesystem:read, and changing them requiresfilesystem:write. A project's files are read or changed only under a registered project's folder.Docs:
docs/user/skills.md.Scope and approval
This is a new feature, and it doesn't have explicit maintainer approval yet. I proposed it in Ideas discussion #15823. On October 6 I posted a working prototype there with a proposed split; two users replied in support, but no maintainer has responded so far. I'm opening the series so the direction can be judged on working code, and I'll reshape, split or close it on your call. It continues the read-only Skills page from #4630, which was closed unmerged. Instructions weren't in the discussion's original list; I've added them there with this series.
Verification
CI's checks at this PR's tip, on Linux x64 with Node 24, all pass:
vp checkandvpr typecheck;vp run build:desktop.The branch is rebased onto
mainated4ea1083d. Part 2's 27 browser checks also pass at this tip.The fixes for the bot reviews are separate commits at the end of this PR's own commits. Each review thread has a reply naming its commit.
Focused tests:
AgentInstructionFiles(the rules table).InstructionCatalog: who reads what, imports, links, Claude's setting, and aCLAUDE.mdthat only imports or linksAGENTS.md.InstructionManager:ClaudeInstructionSetting, the instructions MCP handlers and the web logic tests.In a real browser, against the demo data, there are 47 scripted checks. Each reads the files on disk after the click:
~/.codex/AGENTS.mdto Global.CLAUDE.local.mdpresent, merging appends toAGENTS.md, deletesCLAUDE.mdand turns Claude's setting on;CLAUDE.mdtoAGENTS.md, and the dialog says git can undo it.CLAUDE.mdthat only says@AGENTS.md, or is a link to it, has no row. With Claude turned off, every Claude row is hidden.No console errors, and no horizontal overflow at 390 px.
