Problem

With Settings → Chat → Advanced → Show skills in slash menu off, a Claude thread's / menu still listed every skill. Claude Code advertises each skill twice: once as a skill and once as a native slash command with the same name. The composer only dropped a command when its name matched a visible skill, and with the setting off no skills are visible. So nothing was dropped, and every skill came back as a plain /<name> command. The setting changed nothing.

Reproduced on main cefb544af3 in the web dev server (fresh database, Claude Opus 5.5 thread, 21 personal skills) with the setting off:

• / showed no /skill: rows, but all 21 skills as /<name> commands.
• /cafe listed all seven cafe-* skills.

Change

getProviderSlashMenuEntries(skills, slashCommands, showSkillsInSlashMenu) in packages/client-runtime/src/providerSkills.ts returns both the skill rows and the provider commands. The command filter now drops any command named like a user-invocable skill, whether or not skills are shown. It replaces getProviderSkillsForSlashMenu and getProviderSlashCommandsForSlashMenu, which each caller used to combine itself; the web composer combined them wrong.

• The web composer passes the user's setting.
• The mobile composer has no such setting and passes true, as before.

Ordinary commands (/model, /side, /compact, …) stay. With the setting on, the menu is unchanged.

Scope and approval

Fixes #30184

Verification

• vp test run packages/client-runtime/src/providerSkills.test.ts: 24 passed.
  • New case: "hides a skill's native command along with the skill when skills are hidden".
  • Its first version, committed in 84509e0160, failed on main with expected [ 'cafe-pr', 'compact' ] to deeply equal [ 'compact' ].
  • On this head, putting back the old filter (visible skills only) fails it with the same assertion.
  • The existing alias test now also checks that a skill's command is dropped while the skill is shown.
• vp run check:changed: format, lint, knip, typecheck (7 packages), tests and React compiler all pass.
• Real web app, vp run dev with T3CODE_DEV_SEED=0, Claude Opus 5.5 thread, same 21 personal skills on both sides. Main at cefb544af3, this branch at 333b98c4e6:

Row	Before (cefb544af3)	After (333b98c4e6)
Setting off, /	79 rows; 0 /skill: rows; 21 skills as /<name>	58 rows; 0 /skill: rows; no skill commands; /model, /side, /btw and other commands kept
Setting off, /cafe	7 rows: /cafe-pr, /cafe-api, /cafe-cli, /cafe-admin, /cafe-issues, /cafe-review, /cafe-stacks	"No matching command."
Setting on, /cafe	7 /skill:cafe-* rows, no plain duplicates	Same 7 /skill:cafe-* rows, no plain duplicates
Setting off, $cafe	not checked	7 cafe-* skills (the $ picker still lists them)

The rows above were read from the rendered menu's options. I took screenshots but could not upload them: the evidence upload tool is not set up on the machine that ran this.

Not checked: mobile in a real client. Its change only swaps its two helper calls for the new one and keeps true, so its output is unchanged.

Approvability

Verdict: Approved at 333b98c

Macroscope's review found this PR approvable — Hiding skills now also hides their duplicate provider commands in the slash menu. Defaults, mobile behavior, and the separate skill picker remain unchanged, keeping the impact limited to the existing display preference.

Walkthrough

The client runtime now returns provider skills and slash commands from one helper. It removes commands that match enabled, user-invocable skills even when skill display is disabled. The mobile and web composers use the combined result.

Changes: Provider slash-menu filtering

Layer / File(s)	Summary
Combined skill and command filtering packages/client-runtime/src/providerSkills.ts, packages/client-runtime/src/providerSkills.test.ts	getProviderSlashMenuEntries returns deduplicated, enabled, user-invocable skills when skill display is enabled. It excludes matching slash commands whether or not skills are displayed. Tests cover duplicate names, aliases, enabled-skill selection, and hidden skills.
Composer menu integration apps/mobile/src/features/threads/use-composer-command-menu.ts, apps/web/src/components/chat/useComposerMenuItems.ts	Both composers use the combined result to build command and skill menu items.

Explanation

Linked issue #30184 is the only direct target. Its requirement: with Show skills in slash menu off, a Claude thread must not list user-invocable skills as same-named native slash commands. Ordinary commands must stay.

Evidence at head 333b98c:

• getProviderSlashMenuEntries in packages/client-runtime/src/providerSkills.ts builds invocableSkills from skills.filter(isProviderSkillUserInvocable), deduplicated by name. It builds skillNames from that full invocable list. It removes every slash command whose trimmed, lowercased name is in skillNames. This filter does not depend on showSkillsInSlashMenu. The skill rows are returned only when showSkillsInSlashMenu is true.
• Result: with the setting off, skill-named native commands are removed. Commands that do not match a skill name (for example compact) remain. This matches the issue's proposed fix.
• apps/web/src/components/chat/useComposerMenuItems.ts passes the user's showSkillsInSlashMenu value and the unfiltered selected provider skills and commands. The old code had the same input shape.
• Automated test: providerSkills.test.ts adds "hides a skill's native command along with the skill when skills are hidden". It asserts that cafe-pr is removed and compact is kept with the setting off. The alias test also asserts the command is dropped with skills shown.

Limits: I read the diffs. I did not run the tests. The test results in the PR description are author claims. Real-app behavior in the PR description is also an author claim. Mobile behavior was checked by code reading only. The issue's Claude-specific repro depends on the SDK reporting skills as native commands. This is an external behavior that the diff does not change.

Explanation

All changed files relate to the #30184 fix.

• packages/client-runtime/src/providerSkills.ts: replaces getProviderSkillsForSlashMenu and getProviderSlashCommandsForSlashMenu with getProviderSlashMenuEntries. This is the fix itself.
• apps/web/src/components/chat/useComposerMenuItems.ts: the web composer calls the new helper with the user's setting. This is needed so the web menu uses the fix.
• apps/mobile/src/features/threads/use-composer-command-menu.ts: switches to the new helper and passes true. Its filter input is the same set as before (dedupeProviderSkillsByName of enabled, user-invocable skills), so its output is unchanged. This is a required caller update after the function rename.
• packages/client-runtime/src/providerSkills.test.ts: updates the existing tests to the new helper and adds the regression test for this bug.

No unrelated files, refactors, or documentation changes appear in the diff. The helper signature change is a rename and reshape within the same package. Its callers are both updated.

Preserve ordinary commands with matching skill names.

With skills hidden, a Codex skill named goal also removes the unrelated /goal command. Codex publishes that command separately from its skills. The command was visible before this change. (raw.githubusercontent.com)

Filter only commands known to be skill aliases. Add a regression case for this collision.

Not changing this in this PR. The client can't tell a skill's alias command from a separate built-in command with the same name: ServerProviderSlashCommand has no field for it, and adding one is a contract change beyond this fix. The same collision already hides the command on main when skills are shown (the skill row replaces it). With skills hidden, typing the command in full still works. Marking alias commands on the server would be a separate follow-up.

[coderabbitai]

@juliusmarminge Understood. My “quick win” label understated the required contract change. The name collision remains a menu limitation, but I accept leaving alias metadata to a separate follow-up.

Would you like me to open a GitHub issue for server-provided alias metadata and a regression test for built-in command collisions?

[Demianeen]

Still seeing this on the current build. Anything blocking it from landing?

[juliusmarminge]

Thanks for this. https://git.cafe/pingdotgg/t3code/pulls/30190 makes the same change and is the one being kept.

#30190 fixes the same visibility bug and also handles skills whose native command name differs from their catalog name. That alias handling makes it the more complete fix to keep.

Your diagnosis and regression case capture the underlying problem correctly. We can carry that coverage forward while consolidating the fix into the other pull request.

Closing as a duplicate.
