* feat(agents): add per-agent runtime skill controls

Co-authored-by: multica-agent <github@multica.ai>

* fix(agents): renumber runtime-skill migration and broadcast agent:status on toggle

Address the MUL-5101 review blockers on PR #5686:

- Rebase onto main and renumber the runtime-skill-disable migration
  202 -> 203. main added 202_runtime_profile_add_qwen, so the pair
  collided on prefix 202 and migrations_lint_test would reject the
  duplicate. 203 is the next free prefix.
- Publish an "agent:status" event after persisting a
  disabled_runtime_skills override, mirroring the workspace-skill toggle
  in writeUpdatedAgentSkills. The realtime layer keys off this event to
  invalidate workspaceKeys.agents, so other open web/desktop/mobile
  clients now drop their stale toggle state instead of only the
  initiating tab refreshing. Reload junction-table skills before the
  broadcast so it doesn't signal cleared skills (#3459).
- Add a handler regression test proving the broadcast fires on both
  disable and enable.

a5a42846e6 fix(daemon): retry with a fresh session only when the resume was actually rejected (MUL-4966) (#5715)
* fix(daemon): gate fresh-session retry on tools executed, not session id (MUL-4966)

Switching provider accounts leaves the stored session id pointing at a
conversation the new account does not own. The daemon still passes it to
--resume, the provider rejects it, and the task dies before doing any work.

The existing fresh-session fallback was supposed to catch this but was
gated on `result.SessionID == ""`, which is not a lifecycle fact:

- Too narrow: a backend that echoes the requested id back when it rejects
  a resume keeps SessionID non-empty, so the fallback never fired — the
  reported bug.
- Too broad: a provider 401 before the first stream message also leaves
  SessionID empty, so an unrecoverable auth failure burned a second full
  run.

Gate on `tools == 0` instead. That states the property that actually makes
a retry safe — the agent executed no tool, so it mutated nothing, so
re-running cannot double-post a comment (comment creation has no
idempotency key and a duplicate re-fires its @mention triggers), reopen a
PR, or re-plan on top of its own half-finished work in the reused workdir.
Auth failures are excluded, mirroring retryableReasons in service/task.go.

The predicate is extracted to shouldRetryWithFreshSession so the tests
exercise production logic; both existing fallback tests re-implemented the
condition inline and would not have caught a regression in it.

* fix(daemon): gate fresh-session retry on a positive resume-rejected signal (MUL-4966)

Review of the previous commit was right: `tools == 0` plus "not an auth
error" answers whether re-running is *safe*, not whether a new session can
*fix* the failure. Those are orthogonal, and answering the second by
exclusion inverts the burden of proof — the failures a fresh session cures
are a small enumerable set, while the ones it cannot are open-ended.

Concretely, the previous predicate fresh-retried on provider_network,
429/529, quota, 5xx and unclassified startup failures. provider_network is
the sharpest conflict: internal/service/task.go marks it resume-safe
(MUL-4910) specifically so the platform retry inherits the session and
continues the truncated conversation. Resetting the session first made that
contract unsatisfiable, silently discarding conversation context on a
transient blip — and rate limits got an immediate no-backoff re-run.

Replace the inference with positive evidence: agent.Result gains an explicit
ResumeRejected field, set only when a backend has proof the resume itself
was refused. claude/codebuddy/qwen derive it from resumeWasRejected, which
promotes the predicate resolveSessionID was already computing and encoding
as the side effect of blanking SessionID — using an empty string to carry
that meaning is what made the original bug possible. SessionID keeps being
dropped for a rejected resume (a dead pointer must not be persisted), but it
is no longer the signal the daemon reads to decide *why* a run failed.

The six ACP backends that recover from "session not found" set the flag at
the same points they already clear the id, so their existing recovery is not
caught by the narrower gate. codex needs nothing: thread/resume already falls
back to thread/start in-process, and deliberately does not on transport
errors.

Matching now includes the account-switch guardrail reported in #5704
(Claude Code 2.1.207, zh-CN): "400 此 session 已绑定另外的ai账号,请执行
/new 开启新 session". The en-US wording of the same guardrail has not been
captured yet, so those variants are marked inferred in the source; a miss
degrades to a terminal failure carrying the provider's raw text rather than
a mis-routed run.

Tests: backend-level fixtures drive ResumeRejected from real stream-json for
both the account-binding 400 and a network drop, and the predicate now
covers network/rate-limit/quota/5xx/auth/unclassified as explicit
non-retries.

* fix(daemon): restore fresh-session recovery for backends with no rejection signal (MUL-4966)

Final review caught qwen regressing: its verified rejection string
("No saved session found with ID ...", already captured in
testdata/qwen-code-0.20.0-resume-not-found.stderr.txt) was not in the phrase
list, and qwen reports no session id on that path, so the new inclusion gate
turned a working auto-recovery into a terminal failure.

Auditing the other 17 resume-capable backends showed qwen was not alone.
antigravity, copilot, cursor, deveco and opencode all recovered from a
refused resume purely by reporting an empty SessionID, and none of them has
any rejection detection to convert into ResumeRejected — copilot's own
comment documents the hole (session.error before session.start), and
antigravity's helper returns "" when "the CLI exited before dispatching".
Making ResumeRejected the sole gate silently removed recovery from all five.

Fixing that by guessing rejection phrases for five more CLIs is the wrong
trade: no real output has been captured for any of them, and a false
positive discards a recoverable session pointer. So the gate is now two
tiers. Positive evidence (ResumeRejected) decides on its own where a backend
can produce it. Where none is available, an empty SessionID still gates the
retry — it proves no session was established, which is exactly what the
pre-change behaviour relied on — minus the classes a fresh session provably
cannot cure (network, rate limit, quota, provider 5xx, auth). That keeps the
resume-safe contract in internal/service/task.go intact while restoring what
these five backends had.

Also renames claudeResumeRejectedPhrases to resumeRejectedPhrases: it is
matched by claude, codebuddy and qwen, so a qwen-only string living under a
claude-prefixed name would be actively misleading.

Tests: qwen's existing missing-resume fixture now asserts ResumeRejected
(verified failing without the phrase), and the predicate covers the
no-signal tiers — retry when nothing was established, no retry once a
session exists or the failure classifies as uncurable.

* fix(daemon): scope the no-signal fallback to backends that cannot detect rejections (MUL-4966)

Final review caught the compatibility path applying to every backend, not
just the five it was justified for. shouldRetryWithFreshSession only saw
(Result, priorSessionID, tools), so a false ResumeRejected could not be told
apart from a backend that has no way to answer — and claude/codebuddy/qwen/ACP
startup failures with no session id still fell through to the exclusion
branch. That contradicted both the stated intent and the function's own doc
comment ("where a backend can produce it, it is the whole answer").

Make the capability explicit. agent.ResumeRejectionUndetectable names the
five backends that scrape SessionID out of stream output and have no
rejection detection at all; the daemon takes provider and consults it, so a
capable backend reporting false is now taken at its word. Membership is
opt-in, so a new backend fails closed instead of silently inheriting a
guess-based retry.

Also completes the exclusion set: missing config, unavailable model, missing
executable, unsupported runtime version and (defensively) agent timeout all
have defined non-session remedies and were reaching `default: true`. What is
left through stays narrow — unknown, process failure, unparseable output,
context overflow — because a real rejection from these five most likely
surfaces as a non-zero exit or unparseable output, none of them reporting one
explicitly.

Tests: one identical result asserted across all five undetectable backends
(retries), twelve capable ones (no retry), and an unregistered provider
(fails closed), plus table cases for each newly excluded reason. Classifier
inputs were verified to map to the intended reasons rather than passing by
accident.

Also updates the ResumeRejected doc comment, which still said the daemon
gates on it alone.

c9ceaee4d9 fix(agent): stop stripping user-facing CLAUDE_CODE_* config from child env (#3690)
* fix(agent): stop stripping user-facing CLAUDE_CODE_* config from child env

isFilteredChildEnvKey blanket-removed every CLAUDE_CODE_* var from the
spawned Claude Code child's environment. The intent was only to keep the
daemon's internal session markers from leaking, but CLAUDE_CODE_* is also
Anthropic's user-facing config namespace. On Windows this stripped the
user-set CLAUDE_CODE_GIT_BASH_PATH, so Claude Code could not locate
bash.exe, exited immediately, and every task failed with
"write claude input: write |1: The pipe has been ended."

Switch from prefixing the whole CLAUDE_CODE_ namespace to an exact-name
denylist of the internal runtime/session markers (CLAUDECODE,
CLAUDE_CODE_ENTRYPOINT, CLAUDE_CODE_EXECPATH, CLAUDE_CODE_SESSION_ID,
CLAUDE_CODE_TMPDIR, CLAUDE_CODE_SSE_PORT), still blanket-stripping the
wholly-internal CLAUDECODE_* namespace. Every other CLAUDE_CODE_* var
(GIT_BASH_PATH, USE_BEDROCK, USE_VERTEX, MAX_OUTPUT_TOKENS, ...) now
reaches the child. The internal-marker set was confirmed against the live
runtime, not guessed.

Fixes the whole class, not just git-bash: Bedrock/Vertex/etc. were
silently dropped the same way.

* fix(agent): keep CLAUDE_CODE_TMPDIR in child env

CLAUDE_CODE_TMPDIR is a documented, user-configurable temp-dir override
(public env-vars reference), not an internal per-session marker. Claude
Code creates its own per-session subdir under it, so inheriting it is
harmless — and stripping it would silently break a user's temp-dir
override the same way the broad prefix filter broke CLAUDE_CODE_GIT_BASH_PATH.

Drop it from the internal denylist (which now holds only the undocumented
per-process runtime markers: CLAUDECODE, CLAUDE_CODE_ENTRYPOINT,
CLAUDE_CODE_EXECPATH, CLAUDE_CODE_SESSION_ID, CLAUDE_CODE_SSE_PORT) and
assert it reaches the child.

1e1a4f7845 fix(daemon): fix Copilot CLI invocation on Windows and strip shell quotes from custom args (MUL-2876)
Bug 1: detect copilot.cmd/.bat on Windows and invoke the sibling .ps1 directly via powershell -File, bypassing cmd.exe %* re-tokenisation that mangled the multi-line -p prompt. Shared rewriteCmdToPS1() now serves cursor, pi, and copilot.

Bug 2: filterCustomArgs (shared by all agent backends) strips one outer layer of shell quotes via unshellQuoteArg() before processing, so shell-style custom args like --deny-tool='write' no longer reach the CLI with literal quotes.

a67bf81225 fix(agent): surface host OAuth token via env var on macOS isolation (MUL-2603) (#3267)
* fix(agent): surface host OAuth token via env var on macOS isolation (MUL-2603)

Claude Code 2.x scopes the macOS keychain credentials entry by
sha256(CLAUDE_CONFIG_DIR)[:8], so the MUL-2603 isolation path strands
the child at "Not logged in" even after #3261 mirrored .claude.json:
the child looks up `Claude Code-credentials-<scratch-hash>`, the host
token is sitting in the no-suffix `Claude Code-credentials` entry.

Read the host OAuth token from the keychain via /usr/bin/security and
inject it as CLAUDE_CODE_OAUTH_TOKEN, which bypasses keychain lookup
entirely. Linux/Windows continue to use the .credentials.json mirror
(no-op there). Operator-pinned tokens and ANTHROPIC_API_KEY both take
precedence over the keychain reader.

Co-authored-by: multica-agent <github@multica.ai>

* fix(agent): tighten empty-value auth gate, pin Claude CLI env-scrub assumption (MUL-2603)

Empty-value gate
  - `ANTHROPIC_API_KEY=` inherited from a login shell that conditionally
    exports auth previously posed as an "operator pinned API-key auth"
    choice and disabled the keychain reader, stranding the isolated child
    at "Not logged in" even though no auth was actually selected.
  - Custom_env `CLAUDE_CODE_OAUTH_TOKEN=""` (stale agent config) had the
    same effect, plus would have shadowed a keychain-injected token in
    libc env lookups that pick the first match.
  - Both are now treated as noise: the empty entry is dropped from the
    child env and the keychain reader runs unchanged. Two new unit tests
    cover the os.Environ side (`...TreatsEmptyAnthropicAPIKeyAsUnpinned`,
    `...HonorsNonEmptyAnthropicAPIKey`) and the custom_env side
    (`...EmptyOAuthTokenInCustomEnvAsUnpinned`).

Env-scrub boundary
  - Surfacing `CLAUDE_CODE_OAUTH_TOKEN` to the isolated child is only
    safe because Claude Code itself drops that variable from the env it
    hands to Bash / hook subprocesses, so a model-driven `printenv` can
    never echo the secret into the agent transcript.
  - Empirically verified against `claude` 2.1.121:
        printf '...test -n "$CLAUDE_CODE_OAUTH_TOKEN" && echo SET || echo UNSET...' \
            | CLAUDE_CODE_OAUTH_TOKEN=sk-canary-XYZ \
              MUL2603_CONTROL=control-value \
              claude --print --output-format text \
                     --allow-dangerously-skip-permissions --allowedTools Bash
    returned `UNSET` for the OAuth token while the non-sensitive
    `MUL2603_CONTROL` control returned `CONTROL-SET`, proving the CLI
    scrubs only the auth env, not the env in general.
  - Pinned this assumption in a new skip-gated regression test
    (`TestClaudeCLIScrubsOAuthTokenFromBashSubprocess`) that boots the
    real CLI with a canary token; failing the test means upstream
    Claude Code stopped scrubbing and the passthrough must move off env
    vars before MUL-2603 can ship.

Co-authored-by: multica-agent <github@multica.ai>

* fix(agent): gate keychain passthrough on default host dir, harden scrub test (MUL-2603)

Two follow-ups from the round-2 review on #3267:

1. Custom CLAUDE_CONFIG_DIR no longer pulls the default OAuth token.
   Claude Code 2.x maps each config dir to its own suffixed
   `Claude Code-credentials-<hash>` keychain entry, so an operator that
   pins a managed/custom CLAUDE_CONFIG_DIR via custom_env or the
   daemon-host env was getting the *daemon user's* default unsuffixed
   entry injected into the isolated child — silently crossing accounts,
   exactly the boundary mirrorHostClaudeJSONIfMissing already protects
   for `.claude.json`. buildClaudeEnvWith now threads the effective
   hostConfigDir through and only calls the reader when that dir is the
   default `$HOME/.claude`. The new gate has a unit-level truth table
   (TestIsDefaultHostClaudeConfigDir) plus a regression
   (TestBuildClaudeEnvIsolatedSkipsKeychainForCustomHostConfigDir) that
   makes a t.Fatal-armed reader prove the gate keeps the read off for
   custom dirs.

2. Scrub e2e now asserts the control prong and the proof-of-execution
   marker, not just "canary absent". The previous assertion would
   false-pass on a model refusal, paraphrase, or "Bash gets no env at
   all" upstream change. The strengthened version sets a non-secret
   MUL2603_CONTROL alongside the canary OAuth token and asserts (a)
   canary is NOT in the transcript, (b) CONTROL-SET IS in the
   transcript (env propagation works for non-secrets — proves a
   targeted scrub), (c) UNSET IS in the transcript (the Bash tool
   actually ran AND saw the OAuth var as empty/unset). Code comment in
   buildClaudeEnvWith and the test docstring now narrow the
   security contract to the Bash tool subprocess only; hook subprocess
   env-scrub is no longer claimed because it has not been verified.

Co-authored-by: multica-agent <github@multica.ai>

* test(agent): use per-run nonces in Claude scrub e2e to kill false-pass (MUL-2603)

Elon's round-3 review flagged that TestClaudeCLIScrubsOAuthTokenFromBashSubprocess
still false-passed: the proof markers "UNSET" / "CONTROL-SET" were literal
strings in the prompt, so strings.Contains matched them even when the model
only paraphrased the prompt without spawning Bash.

Replace the hard-coded markers with two per-run random hex nonces passed *only*
via env vars (MUL2603_UNSET_NONCE, MUL2603_CONTROL_NONCE). The prompt now
references the variable names, not the values, so the nonces can land in the
transcript only if a real Bash subprocess inherits the env vars and echoes
them. A paraphrasing or refusing model cannot fake nonces it never saw.

Also update the security-boundary comment in buildClaudeEnvWith to describe
the nonce-based proof.

40da88fc16 fix(agent): mirror $HOME/.claude.json into isolated config dir (MUL-2661) (#3261)
PR #3200 introduced per-agent `skills_local=ignore` isolation that
mirrors the host's Claude config dir into a per-task scratch dir,
omitting `skills/` to keep broken local skills out of the CLI's
discovery path. The mirror walks entries inside `hostConfigDir`
(default: `$HOME/.claude/`), but Claude Code's default layout stores
its main config — login state, project history — at
`$HOME/.claude.json`, a *sibling* of `~/.claude/` rather than inside
it. Once `CLAUDE_CONFIG_DIR=$ISOLATED` is set, the CLI looks for
`$ISOLATED/.claude.json`, finds only `backups/.claude.json.backup.*`
(those live inside `~/.claude/` and DO get mirrored), and exits with:

  Claude configuration file not found at: …/.claude.json
  Not logged in · Please run /login

— so every agent with `skills_local=ignore` on a host using the
default Claude layout dies on the first turn. Flipping the toggle back
to "merge" restores the host CLAUDE_CONFIG_DIR and recovers the agent;
that's the workaround Bohan flagged in MUL-2661.

Fix: after the existing `mirrorHostClaudeExceptSkills`, run a new
`mirrorHostClaudeJSONIfMissing` that pulls `$HOME/.claude.json` into
the scratch dir as `.claude.json` when (a) the dest doesn't already
have one and (b) the host source dir is the default `$HOME/.claude/`.
The custom-CLAUDE_CONFIG_DIR path is left alone because a pinned
custom dir is expected to be self-contained — silently borrowing
`$HOME/.claude.json` from a different account would mask credential
drift.

The helper goes through `createFileLink`, so it inherits the same
symlink → junction → hardlink → copy fallback chain the rest of the
mirror uses on Windows-without-Developer-Mode hosts.

Tests:
- `TestMirrorHostClaudeJSONIfMissing_DefaultLayoutMirrorsParentFile`
  covers the happy path with an injected `homeDir`/`fileLink`.
- `TestMirrorHostClaudeJSONIfMissing_AlreadyPresentNoop` asserts a
  pre-existing dest `.claude.json` (from a custom CLAUDE_CONFIG_DIR
  mirror) is not overwritten.
- `TestMirrorHostClaudeJSONIfMissing_CustomHostDirSkipped` locks in
  the custom-host-dir gate.
- `TestMirrorHostClaudeJSONIfMissing_MissingSourceNoop` documents the
  env-var-auth-only / fresh-install case.
- `TestClaudeExecuteIsolatesProvidesClaudeJSONFromHome` is the
  end-to-end MUL-2661 regression: a fake `\$HOME` with the default
  split layout, `skills_local=ignore`, fake claude binary that prints
  whatever `.claude.json` reaches the scratch dir. Asserts the file
  rides through. Verified the test fails (with the documented
  MUL-2661 error message) when the new mirror call is removed.

Verification:
- `go test ./pkg/agent/...` green (full agent suite).
- `GOOS=windows GOARCH=amd64 go vet ./pkg/agent/...` clean.

960befa56f feat(agent): per-agent toggle to isolate host-machine skills (MUL-2603) (#3200)
* feat(agent): per-agent toggle to isolate host-machine skills (MUL-2603)

Adds an agent-scoped `skills_local` switch ("ignore" default / "merge") so
shared agents stop inheriting the operator's user-global Claude skill
directory. A single broken local skill on one operator's machine was
crashing the Claude CLI before it ever read stdin — the daemon saw a
"broken pipe" with no recoverable signal (GitHub #3052).

- DB: migration 108 adds `agent.skills_local` (NOT NULL DEFAULT 'ignore'),
  with sqlc CreateAgent/UpdateAgent updates and handler validation.
- Claude runtime: when the agent is in "ignore" mode the backend points
  CLAUDE_CONFIG_DIR at an empty per-task scratch dir under the task cwd
  (fallback: OS temp), strips any inherited override, and cleans up after
  the run. Workspace skills under `{cwd}/.claude/skills/` still load.
  "merge" preserves the legacy inherit-from-machine behavior; Codex and
  other isolated backends are no-ops.
- UI: new Skills toggle in the Create Agent dialog and the Agent → Skills
  tab, with EN/zh-Hans copy and SkillsLocalToggle shared between the two.
- Tests: unit coverage for the new env helper, isolation dir lifecycle,
  full Claude execute paths (ignore + merge), and the handler tristate

* fix(agent): preserve claude login + validate skills_local input (MUL-2603)

Address Elon's review on PR #3200:

1. Skill isolation no longer drops the operator's Claude login. The
   per-task scratch dir now mirrors every entry under `~/.claude/`
   as symlinks except `skills/`, so `.credentials.json`, settings,
   plugins, etc. reach the CLI exactly as on the host while the
   user-global skills directory stays hidden. Without this, default
   `ignore` would have broken every Claude agent on a non-API-key
   host the moment migration 108 landed.

2. Internal CreateAgent callers (agent_template, onboarding_shim)
   now set `SkillsLocal: "ignore"`. The Go zero value was about to
   trip the migration-108 CHECK constraint and 500 template /
   onboarding agent creation.

3. Create / update handler validation no longer normalizes garbage
   to "ignore". The strict 400 path is now reachable on bad client
   input; the drift-safe `normalizeSkillsLocal` stays on the read
   side only.

UI copy + docs clarified that the toggle is Claude-only; other
runtimes ignore the setting.

Verification:
- `go test ./...` green (full suite locally).
- `pnpm --filter @multica/views exec vitest run agents/components/tabs/skills-tab.test.tsx` green.
- Handler DB-backed tests still skip locally without docker (same
  as Elon's run) — CI will validate the create / update paths
  against migration 108.

* fix(agent): mirror effective claude config dir with windows fallback (MUL-2603)

Address Elon's second-round review on PR #3200:

1. The per-task scratch dir now mirrors the *effective* host Claude
   config dir, not unconditionally `~/.claude/`. Precedence: agent
   `custom_env` CLAUDE_CONFIG_DIR > parent process env > `~/.claude/`.
   Without this, an operator who pinned Claude at a managed install
   (custom env CLAUDE_CONFIG_DIR) would get the wrong credentials in
   the scratch dir, because `buildClaudeEnv` strips that env before
   handing it to the child. We resolve the source up front and feed
   it to the mirror, so the override env still points at the right
   bytes.

2. Mirror entries now go through platform-aware linkers. On Windows
   without Developer Mode / admin, `os.Symlink` is denied, which
   previously left the scratch dir empty and broke Claude Code auth
   on default `ignore`. The new helpers try symlink first, then fall
   back to a directory junction (`mklink /J`) for dirs or a hardlink
   (same-volume content share) / copy for files. Mirrors the
   execenv/codex_home_link_windows.go pattern.

3. Tests:
   - `TestResolveHostClaudeConfigDir` locks in the custom_env >
     parent_env > `~/.claude` precedence.
   - `TestNewIsolatedClaudeConfigDirMirrorsCustomHostDir` confirms
     the scratch dir picks up `.credentials.json` from a synthetic
     custom host dir, proving the source resolution actually
     propagates into the mirror.
   - `TestNewIsolatedClaudeConfigDirEmptyHostIsNoop` documents the
     env-var-auth-only case (no host source ⇒ empty scratch dir).
   - `TestMirrorHostClaudeExceptSkillsWith_FallbackWhenSymlinkFails`
     exercises the Windows-no-Developer-Mode path via the new
     `mirrorHostClaudeExceptSkillsWith` seam, asserting credentials
     and sub-dir children still reach the scratch dir after the
     symlink stand-in fails.
   - `TestMirrorHostClaudeExceptSkillsWith_PropagatesFirstLinkError`
     confirms callers see the per-entry error when even fallback
     fails (so the warn-log fires on broken Windows installs).
   - `TestCopyFileRoundTrip` covers the last-resort copy fallback
     and its EXCL no-overwrite contract.
   - `TestClaudeExecuteIsolatesUsesCustomEnvSource` is the
     end-to-end check: an agent with custom_env CLAUDE_CONFIG_DIR
     reads its credentials from the pinned dir, not `~/.claude/`.

4. Docs: `apps/docs/content/docs/skills.{mdx,zh.mdx}` updated to
   describe the effective-source resolution and the Windows
   fallback chain so the docs match the runtime behaviour.

Verification:
- `go test ./...` green (full server suite locally, including
  `pkg/agent` 23 cases covering the new + existing isolation
  paths).
- `GOOS=windows GOARCH=amd64 go vet ./pkg/agent/...` and
  `go test -c -o /dev/null` both compile clean, confirming the
  Windows-tagged linker file builds.

* fix(agent): default skills_local to merge to preserve legacy behavior (MUL-2603)

Per Bohan's product decision on PR #3200, the per-agent host-skill toggle
defaults to "merge" — the pre-MUL-2603 inherit-from-machine behavior —
so existing personal workflows that rely on locally installed Claude
Skills keep working unchanged. Agent owners explicitly opt into "ignore"
when they need to harden a shared agent against a broken local skill on
one operator's machine (GitHub #3052).

Also audited all 11 runtimes for user-global skill discovery paths and
documented the scope of the toggle. Only Claude reads a user-global
`~/.claude/skills/`; Codex isolates via `CODEX_HOME`, the ACP backends
(Hermes / Kimi / Kiro) and the JSON-stream backends (Copilot / Cursor /
Gemini / Pi / OpenCode / OpenClaw) anchor discovery to the task workdir
and never read a user-global skill directory. UI copy and docs now say
"for runtimes that support it (currently Claude Code)" everywhere so
the scope is explicit.

Changes:

- Migration 108: column default flipped to 'merge'.
- Handler CreateAgent: missing field → "merge"; explicit "ignore" /
  "merge" still validated, garbage still 400.
- normalizeSkillsLocal: drift-safe coercion now lands on "merge" for
  anything that isn't the exact literal "ignore".
- agent_template.go / onboarding_shim.go: internal CreateAgent callers
  send "merge" instead of "ignore" to match the new default.
- Claude runtime (`claude.go`): isolate-mode gate flipped from
  `SkillsLocal != "merge"` to `SkillsLocal == "ignore"`, so "" (legacy
  daemons / older clients) and "merge" both walk `~/.claude/` directly.
- Create Agent dialog + Skills tab: toggle defaults to on (merge); only
  duplicate of an explicit "ignore" agent carries through. The
  isolation opt-in is now `skills_local: "ignore"` when the user flips
  off; "merge" is omitted from the request body.
- i18n (EN + zh-Hans): copy reframed — "On (default) — merged"; "Off —
  ignored. Recommended for shared agents".
- Docs (`/skills`, `/guides/agents.zh`): describe new default and
  enumerate which runtimes act on the toggle.
- Landing changelog 0.3.7: retitled "Per-Agent Local-Skill Toggle"; note
  the on-by-default behavior + off-to-isolate framing.
- Tests:
  - `TestClaudeExecuteIsolatesHostSkillsWhenIgnoreOptedIn` replaces the
    old by-default isolation case (now requires explicit "ignore").
  - New `TestClaudeExecuteDefaultModeKeepsHostConfigDir` locks in that
    default ExecOptions preserve the host CLAUDE_CONFIG_DIR.
  - `TestClaudeExecuteIsolatesUsesCustomEnvSource` now explicitly opts
    into "ignore" mode.
  - Handler tests: omitted → "merge"; explicit "ignore" round-trips;
    preserve-existing test seeds "ignore" and asserts "merge" flip-back.
  - `TestNormalizeSkillsLocal_DriftStaysSafe`: only literal "ignore"
    maps to ignore; everything else → "merge".
  - `skills-tab.test.tsx`: toggle ON by default; flip OFF when agent
    opted into "ignore". Intro-text matcher anchored to a more specific
    phrase so it no longer collides with the toggle hint copy.

Verification:
- `go test ./...` green (full server suite locally).
- `GOOS=windows GOARCH=amd64 go vet ./pkg/agent/...` and
  `go test -c -o /dev/null` both compile clean (windows-tagged linker
  file still builds).
- `pnpm typecheck` green across all packages and apps.
- `pnpm --filter @multica/views test` 88 files / 771 tests green.
- `pnpm --filter @multica/core test` 43 files / 390 tests green.
- Handler DB-backed tests still skip locally without docker; CI will
  validate the create / update paths against migration 108.

* fix(agent): propagate skills_local=ignore to codex user-skill seed (MUL-2603)

Make the per-agent skills_local toggle real for Codex too, not just Claude.
Previously the toggle was only consumed by the Claude backend, while the
daemon's execenv layer always seeded Codex's per-task CODEX_HOME with the
host machine's user-installed skills from ~/.codex/skills/. A shared Codex
agent with skills_local=ignore could still inherit a broken local skill
from one operator's machine.

Now: PrepareParams/ReuseParams carry SkillsLocal; hydrateCodexSkills
skips seedUserCodexSkills when SkillsLocal == "ignore" so the per-task
CODEX_HOME exposes only workspace skills to the codex CLI. Default
("merge", or empty from older servers/clients) preserves existing
inherit-from-machine behavior. UI / docs are updated to reflect the
contract honestly: Claude Code and Codex honor the toggle; other
runtimes (Hermes / Kimi / Kiro / Copilot / Cursor / Gemini / Pi /
OpenCode / OpenClaw) leave $HOME untouched and discover user-level
skills natively, so the toggle is a no-op for them today.

New tests: TestPrepareCodexSkillsLocalIgnoreSkipsUserSeed,
TestPrepareCodexSkillsLocalMergeSeedsUserSkills, and
TestReuseCodexSkillsLocalIgnoreSkipsUserSeed cover Prepare(ignore),
Prepare(merge), and the toggle-flip-on-reuse path.

* docs(skills): scope skills_local toggle copy to Claude Code + Codex (MUL-2603)

Off-state hint and Skills tab intro now explicitly call out Claude Code +
Codex as the only runtimes that honor the toggle, with "other runtimes
ignore this setting" wired into both states (en + zh-Hans), so users on
non-Claude/Codex agents don't read "Off" as runtime-wide isolation.

Docs (skills.mdx, skills.zh.mdx, guides/agents.zh.mdx) stop describing
Hermes / Kimi / Gemini / Copilot / Cursor / Pi / OpenCode / OpenClaw / Kiro
as having native user-level skill discovery; the daemon simply does not
manage user-level skill discovery for those runtimes today, and the toggle
is a no-op regardless of where it is set.

8d872b7521 fix(daemon): disable Claude AskUserQuestion in non-interactive mode (MUL-2244) (#2656)
* fix(daemon): disable Claude AskUserQuestion in non-interactive mode (MUL-2244)

GitHub #2588: when Claude Code calls its built-in AskUserQuestion tool
inside the daemon's stream-json runtime, the question never reaches the
user — there's no UI to render it — so the SDK returns an empty answer
and the agent silently "infers" and continues. From the issue's
perspective, execution looks stuck while the agent is actually charging
ahead on its own guess.

Two-part fix:

- `buildClaudeArgs` now passes `--disallowedTools AskUserQuestion` so
  the tool is not exposed to the model at all.
- The Claude-specific runtime brief tells the agent to use a `blocked`
  issue comment for genuine clarification, or to state an explicit
  assumption and proceed.

Adds a regression test that pins both: AskUserQuestion is forbidden in
CLAUDE.md and is NOT mentioned in the AGENTS.md emitted for non-Claude
providers (the tool is Claude-specific).

Co-authored-by: multica-agent <github@multica.ai>

* refactor(daemon): drop CLAUDE.md AskUserQuestion guidance, rely on --disallowedTools

The --disallowedTools flag already prevents Claude from invoking
AskUserQuestion, so duplicating the rule in the runtime brief just bloats
the prompt without changing behavior. Removes the section and its
regression test; the argv-level test in pkg/agent already pins the flag.

aca74293dd fix(agent/claude): surface stderr tail on writeClaudeInput failure + lock with e2e test (#1698)
#1674 wired claude's post-handshake error path through withAgentStderr but
left the writeClaudeInput failure branch returning a bare "broken pipe"
error. That branch fires precisely when claude crashes during startup —
exactly when the stderr tail is most useful for root-causing V8 aborts,
Bun panics, or missing native modules. cmd.Wait() before sampling Tail()
flushes os/exec's internal stderr copy goroutine, matching the
Wait→Tail synchronization contract spelled out in stderr_tail.go.

Adds TestClaudeExecuteSurfacesStderrWhenChildExitsEarly mirroring the
codex test: a fake claude binary drains stdin, writes a V8-abort line to
stderr, and exits 3. Locks in the contract that Result.Error carries the
stderr tail in the post-handshake failure path on the claude backend too.

746f33a38b fix(claude): clear fresh session_id on resume failure so daemon fallback fires (#1285)
When --resume targets a dead session, claude prints
"No conversation found with session ID: ..." to stderr, emits a stream-json
system init with a fresh session_id, then exits with code 1. The backend
was treating that fresh id as the authoritative session, so
daemon.go's retry-with-fresh-session fallback (SessionID == "" guard)
never triggered. Every subsequent task for the same (issue, agent) pair
stayed permanently broken until the server-side session_id was cleared by
hand.

Fix: when --resume was requested but the emitted session_id differs AND
the run failed, drop the fresh id from Result so the daemon's existing
fallback can do its job. Factored into a pure helper and unit-tested.

Fixes #1284

63800f05ff fix(agent): add per-agent mcp_config field to restore MCP access (#1168)
* fix(agent): add per-agent mcp_config field to restore MCP access

Closes #1111

The --strict-mcp-config flag was added defensively in #592 to prevent
Claude agents from inheriting MCP state from the outer Claude Code session.
It was meant to be paired with --mcp-config <path> to inject a controlled
set of MCPs, but that path was never implemented, which silently stripped
all user-scope MCPs from spawned agents.

This PR completes the original design by:

- Adding a nullable mcp_config jsonb column to the agents table
- Wiring mcp_config through AgentResponse, Create/Update requests
- Piping it into ExecOptions.McpConfig in the daemon
- Serializing to a temp file and passing --mcp-config <path> in buildClaudeArgs
- Blocklisting --mcp-config in claudeBlockedArgs to prevent override
  via custom_args

Does not touch Codex provider (tracked separately in #674).
Does not implement Multica MCP auto-injection (out of scope).

ce447c7f06 feat(agent): add custom CLI arguments support (#986)
* feat(agent): add custom CLI arguments support

Allow users to configure custom CLI arguments per agent that get
appended to the agent subprocess command at launch time. This enables
use cases like specifying different models (--model o3), max turns,
or other provider-specific flags without needing separate runtimes.

Changes:
- Add custom_args JSONB column to agent table (migration 041)
- Update API handler to accept/return custom_args in create/update
- Pass custom_args through claim endpoint to daemon
- Append custom_args to CLI commands for all agent backends
- Add ExecOptions.CustomArgs field in agent package
- Add Custom Args tab in agent detail UI
- Add --custom-args flag to CLI agent create/update commands

Closes MUL-802

* fix(agent): filter protocol-critical flags from custom_args

Add per-backend filtering of custom_args to prevent users from
accidentally overriding flags that the daemon hardcodes for its
communication protocol (e.g. --output-format, --input-format,
--permission-mode for Claude).

This follows the same pattern as custom_env's isBlockedEnvKey: we
only block the small, stable set of flags that would break the
daemon↔agent protocol — not every possible dangerous flag. Workspace
members are trusted for everything else.

Each backend defines its own blocked set:
- Claude: -p, --output-format, --input-format, --permission-mode
- Gemini: -p, --yolo, -o
- Codex: --listen
- OpenCode: --format
- OpenClaw: --local, --json, --session-id, --message
- Hermes: none (ACP is positional)

Includes unit tests for the filtering logic.

* fix(agent): address code review nits for custom_args

- Replace module-level `nextArgId` counter with `crypto.randomUUID()`
  in custom-args-tab.tsx to avoid SSR ID conflicts
- Add unit tests for custom args passthrough and blocked-arg filtering
  in both Claude and Gemini arg builders
