Claude exposes user-invocable skills as both skills and native slash commands. Turning off Show skills in slash menu hid the skill rows but let their duplicate native commands back into the menu. Deduplicate against all user-invocable skills for the selected provider/workspace, independently of the visibility setting. Keep differing native aliases searchable so /sandbox still finds the boat skill when skills are shown.

Fixes #30184. This is a small, focused fix for an existing setting that did not work as documented; no product defaults or new workflow change. Web and desktop share this composer. Mobile has no equivalent toggle and already filters against all user-invocable skills; its slash-skill search now also recognizes native aliases. Claude discovery supplies an optional slashCommandName in the skill catalog for differing native aliases. Other provider adapters and connection modes are unchanged.

Verification after modernization onto eeb6e23675: the alias query regression failed on the previous PR implementation, then passed after the fix. Focused suites passed all 65 tests. vp run check:changed refs/t3-modernize/30190/verify-base --concurrency 1 passed format, lint, both knip passes, GraphQL, 74 tests, and affected React Compiler cases. Its typecheck step failed on the existing ACP TS2345 at packages/effect-acp/src/protocol.ts:817; the same error reproduces on clean upstream main with vp run --filter effect-acp typecheck. All test/check launches cleared display credentials and Chromium ran headless. Direct typechecks for web, mobile, contracts, and client-runtime also passed. Native clients and the integrated real client were not rerun during this modernization.

Earlier, in the real web client on an isolated Linux development server, checked Claude's overlapping skill/command catalog: /full-stop disappeared with the setting off, $full-stop still worked, and turning the setting on restored exactly one skill row. Windows/Electron were not run separately.

Approvability

Verdict: Approved at e4d7462

Macroscope's review found this PR approvable — The change makes skill-backed slash commands respect the existing skill-visibility preference. Its effect is confined to composer suggestions, with no changes to command execution or stored settings.

Walkthrough

Claude skill discovery now retains a differing frontmatter name as a slash-command name. Provider-command filtering and mobile and web skill search check that name. Composer menu generation uses all selected-provider skills for provider commands, regardless of the skill visibility setting.

Changes: Provider skill slash-command filtering

Layer / File(s)	Summary
Expose skill slash-command names packages/contracts/src/server.ts, apps/server/src/provider/Drivers/ClaudeSkills.ts, apps/server/src/provider/Drivers/ClaudeSkills.test.ts	The server skill contract accepts an optional slashCommandName. Claude discovery sets it when a non-plugin skill has a differing frontmatter name. Tests check the alias and retain the directory name as the skill identity.
Match skills by slash-command name packages/client-runtime/src/providerSkills.ts, apps/mobile/src/features/threads/composerSlashSkillSearch.ts, apps/mobile/src/features/threads/use-composer-command-menu.test.ts, apps/web/src/providerSkillSearch.ts	Provider-command filtering checks normalized skill names and slash-command names. Mobile and web skill search also checks the slash-command name. Mobile tests cover matching by skill name, slash-command name, and a skill:-prefixed query.
Apply skill visibility in the composer menu apps/web/src/components/chat/useComposerMenuItems.ts, apps/web/src/components/chat/useComposerMenuItems.browser.test.tsx	Provider-command generation uses all selected-provider skills rather than the visibility-filtered skill list. Skill suggestions continue to use the slash-menu skill list. Browser tests check menu labels and query results with skills hidden or shown.

Explanation

[#30184] The web composer filters provider slash commands against all user-invocable skills, not only skill rows shown in the menu. useComposerMenuItems.ts passes skills with visibility enabled to the command filter, while it applies the user setting separately to skill rows. providerSkills.ts removes commands that match a skill name or slashCommandName. This preserves ordinary commands. The supplied change summary reports browser coverage for the setting and alias queries, plus Claude discovery tests for slashCommandName.

Explanation

The Claude alias field, contract update, and web and mobile alias search support matching and finding skills when the native command name differs from the skill name. The supplied change summary identifies no unrelated changes. Tests cover these behaviors.

Make the skill searchable by its alias.

When boat has slashCommandName: "sandbox", this removes /sandbox from the menu. With skills enabled, scoreProviderSkill in apps/web/src/providerSkillSearch.ts does not search slashCommandName, so typing /sandbox no longer finds the skill. Include the alias in skill search and cover that query in the existing browser test. (raw.githubusercontent.com)

Review comment at @packages/client-runtime/src/providerSkills.ts at line 60:
Update the skill search flow so `scoreProviderSkill` also searches
`slashCommandName`, ensuring a skill with the alias `sandbox` can be found by
typing `/sandbox` when skills are enabled. Add coverage for that query to the
existing browser test, while preserving the current skill-name search behavior.

Verified in a real dev environment

Verified unchanged head 8f955687e836829e307bde2bca8b0c98c0baaf70 on a Linux Boat VM with the real web client, repository Playwright, and /usr/bin/google-chrome.

• Reproduced on github/main at 3d369d5596: with "Show skills in slash menu" off, Claude's real /sandbox command still appeared for the installed boat skill.
• On this PR, the same query and setting show "No matching command." Turning the setting on restores exactly one /skill:boat row; turning it off hides it again.
• With skills off, $boat still finds the skill and selecting it inserts its skill chip. /model still opens the model picker. Also checked the hidden-command result at 1000×800 in dark mode.
• Created the project and threads through the app against a real Git repository. Real Codex gpt-6.1-sol and Claude Haiku 5.5 turns used the local proxy and read README.md. Claude's /compact completed, and a subsequent turn retained the answer. No mocked catalogs, seeded databases, replay providers, or fixture data.
• vp run check:changed cefb544af3c98224874419198c0359b652ca3c94 passed through blacksmith-check: format, lint, knip, GraphQL, 36 affected package typechecks, 52 tests across five files, and React Compiler validation. The worker's missing Chromium dependency was installed before the passing run.

Native Electron, iOS, Android, macOS, and Windows clients were not exercised on this Linux web setup. Remote/relay/tunnel connections, other providers, and OAuth subscription authentication were not exercised. Provider turns here used the VM's existing local proxy credentials. The installed skill was boat with Claude alias sandbox; other plugin skill catalogs were not available here.

Include the native alias for plugin folder skills.

When a plugin skill’s frontmatter name differs from its directory name, Claude can expose plugin:review-alias while discovery supplies only plugin:review. The command remains visible when skills are hidden. Record the namespaced frontmatter alias in slashCommandName for this case.

Evidence

Real web client, Chromium on Linux, 1280×800, light theme; fresh isolated state and identical synthetic Claude skills on each commit. Install pstack:bro and personal skill boat with native alias sandbox. Disable Show skills in slash menu, inspect /, /pstac and /sandbox; check $boat; re-enable and check the restored skill rows.

The scenario failed on base and passed on head. Base leaked native skill commands while disabled. Head hid them, retained ordinary commands and $boat, and restored single skill rows when enabled.
