Problem

Claude loads personal plugins placed inside its skills directory without an installed-plugin registry entry. Their namespaced skills are missing from T3's $ picker and mid-message slash skill rows, so $demo-tools:review remains literal text instead of dispatching the loaded native skill.

Reproduced with Claude Code 2.1.303 on Linux using a named plugin manifest and a nested skill symlink to a live source directory, with no root SKILL.md or registry entry. The native leading slash command was available while the two filesystem-backed skill menus were empty.

Change

Discover personal skills-directory plugins alongside installed plugins, using the existing manifest and skill-root logic. Respect explicit enablement and manifest defaults, require a valid namespace, and retain live skill symlinks. Apply managed source restrictions before personal adoption and preserve namespaces held by enabled installed plugins. Folders containing a root SKILL.md stay ordinary skills; project plugin adoption is unchanged.

Add focused discovery regressions and replayable filesystem fixtures with a user-text-only CLI observer for dispatch proof. There are no contract or client changes.

Scope and approval

Fixes #23507 GitCafe: https://git.cafe/pingdotgg/t3code/issues/23507 Triaged bug via the automated issue flow: #23507, GitCafe report. This restores selection and dispatch for skills already loaded by Claude.

Verification

Red regression on main: discovery returned [] instead of demo-tools:review for the named, symlinked, unregistered personal plugin.
vp test run apps/server/src/provider/Drivers/ClaudeSkills.test.ts apps/server/src/provider/Drivers/ClaudeSkillDispatch.test.ts: 30 passed before integration; final integration run recorded below.
Server tsc --noEmit: passed. Scoped lint/format passed for the driver, tests, and replay utilities; committed observer smoke passed with a nonempty user-text record.
Real web checks: both menu paths; keyboard/click selection; chip removal, dismissal and reopening; slash-menu visibility; disable/re-enable after completed workspace refresh; fresh-turn and active-turn steering native dispatch. Disabled and agent-only skills remained literal in dispatch.

Evidence

Full evidence index, replay instructions, conditional fixture matrix and limits. Eight matched still pairs and four narrated recording pairs. Before is ff525478e2; after is 396d43d148.

Linux Chrome 154, DPR 2, 100% zoom/font scale, CSS 1440×900 and 390×844, light/dark, same seeded Reply OK history, collapsed sidebar, scroll 0. Stills freeze the clock at 2026-10-22 09:40 UTC; recordings use real time. Desktop preview stills are resampled to 1280×800; narrow stills are 780×1688. No native-device emulation.

Visible differences: empty popups become namespaced skill rows and their Personal badges; long names/descriptions truncate at 390px. The narrow dark slash pair also contains a small submit-button texture difference unrelated to discovery. Zero-threshold diffs are amplified 8×; threshold overlays mark per-channel differences above 16/255. No regions are excluded.

R1 after desktop: Enter 1.37s, click 4.03s, deletion 5.80s, leading slash 7.48s, Escape 8.75s, reopen 10.01s. Narrow equivalent: 1.34/4.00/5.80/7.15/8.42/9.67s.

R2 after: off 5.59s, on 9.88s; machine refresh 32.16s still leaves the cached workspace inventory, so recording continues until genuine workspace expiry/refresh. Disabled absence at 136.27s. Two recorded segments are joined: second segment resumes after the normal five-minute TTL wait; enabled dollar/slash restored once at segment2 3.35s. Raw parts retained. No forced clock advance or injected snapshot. Before Settings refresh completes disabled/enabled while adoption remains absent.

R3 after: first fresh send at start; first attempted steer at 28.01s landed after completion and is retained as a fresh-turn control. Actual new active turn begins 53.37s; Stop generation establishes activity; Ctrl+Enter while Queue message visible at 55.37s. Outbound fresh at 10:08:33.485Z and steer at 10:08:34.348Z (same PID) each end with a separate /demo-tools:review text block and preserve the preceding request. Persisted turn-item event marks inputIntent:steer at 10:08:34.288Z. Before actual active inputs at 09:49:14.079/.498Z remain literal $demo-tools:review. All requested turns explicitly forbid tools/file edits and request only OK.

after-negative-controls.mp4 — agent-only unavailable and sent as literal text; disabled plugin native dispatch absent despite an already cached composer chip.

Limits

Electron/macOS and native mobile, relay/tunnel, and other providers were not executed. The 390px captures verify responsive web only. The code change is Claude server discovery with an unchanged wire contract.

The conditional matrix explicitly lists unverified filesystem failure branches, a direct manifest path to a SKILL.md file, canonical plugin-name collisions, and a separate ordinary-project fixture. Existing shared-root tests remain in place. No full crossproduct of registry scope and helper shapes is claimed.

Independent proof audit: SUFFICIENT. Replay from a new benign app thread matched the popup and composer exactly; 588/1,024,000 pixels differed in the sidebar control, with zero above 16/255. The updated evidence index includes the exact real-app thread setup recipe.

Merged current main 8d3b061121 into the fix branch as 6b98e6a965. All five changed file blobs are unchanged from the audited capture head. Scoped discovery/dispatch tests and server typecheck were rerun after integration.

CI follow-up: knip files/dependencies analysis now passes after moving the three replay fixtures from provider/testing/ to the existing provider/testFixtures/ entry directory. For replay at the latest head, use apps/server/src/provider/testFixtures/ClaudeSkills.fixture.mjs and ClaudeStdin.fixture.mjs; the evidence-head paths in the archived index remain historical. The observer now preserves UTF-8 across stdin chunks and final lines without a newline. Split-character smoke proof preserves héllo 日本 🎉 and forwards identical bytes; append failures still exit nonzero. Scoped lint and format pass. These fixture-only corrections leave the audited production and render behavior unchanged.

Native guard-branch proof and red/green results extend the historical capture proof at d4fe68f3aa. Native Claude Code 2.1.303 confirms managed allowlist/blocklist and customization locks suppress personal plugins, and an installed plugin holds its namespace over a personal copy. Two new regressions fail before the correction; all 32 discovery/dispatch tests now pass. Server typecheck, scoped lint/format and knip files/dependencies pass. Observer path normalization rejects traversal while preserving Unicode and raw forwarded bytes. The original menu fixture has no managed restriction or namespace collision, so its captured behavior is unchanged; these added suppression branches are proved by native runtime transcripts and tests.

Remaining parity limits: managed-settings drop-in directories and cross-origin managed enabled-plugin name locks were not verified; existing lenient managed-JSON parsing differs from native strict parsing. The native transcript details these limits. No native mobile, Electron or remote execution was added by this follow-up.

Observer backpressure and native precedence follow-up: a slow-reader smoke forwards identical bytes with peak observer RSS reduced from 171.4 MB to 58.5 MB. The observer-only fix is 9458cbb. All 32 focused tests, scoped lint/format and full knip pass. Native directory-marketplace probing retains installed-name precedence even with an absent registry install path; remote-source probes timed out and are explicitly inconclusive.

Observer permission proof for 0e987b4d: existing permissive logs are tightened to 0600 before appending, confirmed by syscall order. New-file mode, concurrent append, split Unicode, raw forwarding and nonzero filesystem failures pass smoke checks; scoped lint/format and full knip pass. Production behavior is unchanged by this fixture-only follow-up.

Observer signal handling: smoke tests confirm forwarded SIGTERM/SIGINT terminate the wrapper with the same signal; exit codes 0 and 3 remain unchanged, UTF-8 logging remains intact, and scoped lint/format plus vp run knip:check pass. Before/after signal proof. This fixture-only follow-up does not change production behavior. Implemented with Claude Opus 5.5 through Claude Code; issue lead, tests/review coordination and evidence with GPT-6.1-Sol through Codex.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Personal skills-directory plugins now appear automatically in skill menus and participate in mention dispatch, subject to enablement and managed-policy guards. This expands default skill availability and requires human acceptance of that behavior.

Walkthrough

Claude skill discovery now scans eligible personal plugins under ~/.claude/skills. Managed settings can block those plugins. Discovery uses manifest names and enablement settings, validates plugin roots, and gives installed plugins precedence for duplicate names.

Changes: Claude Skills-Directory Discovery

Layer / File(s)	Summary
Managed policy and plugin skill roots `apps/server/src/provider/Drivers/ClaudeSkills.ts`	Managed settings determine whether skills-directory plugins are allowed. Manifest helpers read plugin manifests and collect default and declared skill roots, with path checks for declared roots.
Installed and personal plugin discovery `apps/server/src/provider/Drivers/ClaudeSkills.ts`, `apps/server/src/provider/Drivers/ClaudeSkills.test.ts`	Discovery collects installed plugin roots, then scans eligible personal plugin folders when policy allows. Tests cover folder eligibility, enablement, managed policy, symlinked skills, and name collisions.

Managed restrictions appear to be applied. A stale installed-plugin record may still hide a usable personal plugin; confirm that precedence case before merging.

Explanation

The description includes complete Problem, Change, Scope and approval, and Verification sections. It documents reproduction details, implementation scope, linked issue and approval context, focused test results, evidence, and known verification limits.

Full details: Linked Issues check

Explanation

The implementation satisfies the coding requirements in #23507. discoverPluginSkillRoots scans personal skills entries, reads named manifests, honors defaultEnabled and enabledPlugins, rejects invalid namespaces, skips root SKILL.md folders, and preserves declared skill paths including symlinks. It gives enabled installed plugins namespace precedence. The focused tests cover the unregistered manifest case, live symlinks, enablement, defaults, eligibility, managed restrictions, and namespace collisions.

Full details: Out of Scope Changes check

Explanation

The changes remain within #23507. Managed-policy checks, installed-plugin precedence, compatibility coverage, and observer or replay fixture updates support discovery and dispatch verification. The reported typecheck, focused tests, lint, format, and knip checks support the change. No unrelated client, contract, or provider behavior is shown.

fix(server): honor managed policy and installed-name precedence for skills-dir pluginsd4fe68f

JJulius Marminge20d ago

Fixed the managed-policy, installed-namespace precedence, and observer path findings in d4fe68f3aa. Native runtime transcript and red/green proof: 32 focused tests pass, with scoped lint/format, typecheck and knip clean. Native Claude 2.1.303 also suppresses skills-directory plugins under managed strictPluginOnlyCustomization; the guard includes that setting based on runtime evidence.

test(server): stdin observer respects child backpressure9458cbb

JJulius Marminge20d ago

Fixed observer backpressure in 9458cbb; slow-reader proof shows identical forwarded bytes and peak RSS reduced from 171.4 MB to 58.5 MB.

The proposed missing-install-path guard is not applied: in the native directory-marketplace control, Claude loads from the marketplace folder and rejects the personal copy even when the registry install path is absent. Checking only path existence would advertise skills native refuses. Remote-source variants timed out and are inconclusive; those limits are recorded in the linked transcript.

fix(server): Claude stdin observer tightens an existing log to 06000e987b4

JJulius Marminge20d ago

Fixed in 0e987b4d. The observer enforces 0600 on the opened descriptor before appending and closes it in finally. Smoke proof includes syscall ordering, existing/new file permissions, concurrent append, Unicode/byte forwarding and write failure checks.

Preserve forwarded signal termination.
When the wrapper receives SIGTERM or SIGINT, it forwards the signal to child. Node reports code === null and provides the signal separately. The current handler then exits with status 1, so the observer does not preserve the child’s signal termination.

fix(server): Claude stdin observer exits with its child's signal258518e

JJulius Marminge20d ago

Fixed the outside-diff signal-termination finding in 258518e. The observer removes its forwarders before mirroring the child’s terminating signal; ordinary exit codes are preserved. Before: SIGTERM/SIGINT both became exit 1. After: -15/-2 respectively; exit 0/3 and UTF-8 logging remain intact. Scoped lint/format and knip pass. Smoke proof.

chore(server): drop manual Claude replay fixtures from the skills-dir fix582a6aa

Evidence

Evidence captured in Chromium at 1280×800, light theme, with fresh isolated databases and identical synthetic plugin configuration. Claude listed demo-tools@skills-dir as loaded. In a fresh Claude composer, enter $demo-tools, then Please /demo-tools.

	Before	After
Commit	3a8c250cb0	582a6aaef0
Dollar picker	Before: no skills found	After: demo-tools:review with Personal scope
Mid-message slash picker	Before: no matching command	After: namespaced Personal skill
Recording	Before interaction	After interaction, including disable/re-enable and selection

The scenario failed its missing-skill assertion on base and passed on head. Head also removed the skill after disablement and a fresh workspace scan, restored it after re-enablement, and inserted a skill chip on selection. Recordings show the composer crop at one-third speed; startup is trimmed and the private model control is masked.

Scenario · Seed script · App launcher · Reproduction notes · Full proof summary.

Uploaded scripts redact local configuration paths and private model labels. Native execution remains unverified because the isolated Claude configuration has no authentication. AI-assisted; verified with the tests and tools listed above.

Not shown:

Native slash-command advertisement and dispatch of selected or typed skills: the isolated Claude configuration was unauthenticated, so no native turn was executed.
Disable/re-enable and selection were supplemental head-only checks; base stopped at its missing-skill assertion.
