feat(web): option to hide built-in skills from the / and $ menus - #31731
The / and $ skill menus list every skill a provider ships with, alongside the user's own. With Cursor, that adds about a dozen built-in skills from ~/.cursor/skills-cursor (create-rule, create-skill, autopilot, loop, sdk, share, and others), discovered since #24595. Users who keep their own skills have no way to narrow the menus to them. "Show skills in slash menu" is all or nothing and does not affect $. Cursor has no setting for this either, and it restores the folder if you delete it (Cursor forum request, cursor/plugins#130).
To reproduce, open a Cursor thread and type $ or /. Cursor's built-in skills are listed next to personal and project skills, and no setting hides only them.
Change
Adds a Show built-in skills switch, on by default, under the Advanced section next to "Show skills in slash menu".
showSystemSkills client setting in packages/contracts/src/settings.ts. It defaults to true, so nothing changes until a user turns it off.
filterProviderSystemSkills in packages/client-runtime/src/providerSkills.ts. It drops skills whose source resolveProviderSkillSourceKind already reports as system, the same classification behind the System badge. Today that covers Cursor's skills-cursor root and Codex's system-scoped skills.
useComposerMenuItems applies the filter to the skill rows in / and to $ search. Provider slash commands are still deduplicated against the unfiltered skill list, so a hidden skill cannot come back as a duplicate native command.
Discovery, mention chips, and invocation are unchanged. Typing $create-skill by hand still runs the skill. The option only controls what the menus list.
Scope and approval
This is a focused configuration option for an existing capability, so there is no prior discussion. The composer already discovers provider skills, labels them by source, and shows built-in ones with a System badge. The existing "Show skills in slash menu" setting already controls whether skills are listed. The new option filters those same lists by the source T3 already computes, and it is off only when a user chooses. It does not add a workflow, change a default, or change what the agent can run.
The mobile composer is unchanged. It does not read "Show skills in slash menu" either.
Verification
packages/client-runtime/src/providerSkills.test.ts: new cases check that every skill is kept while system skills are shown, that only system skills are dropped (scope matching is case- and whitespace-insensitive) while user, project, and unscoped skills stay, and that a hidden system skill no longer shadows a same-name skill in /.
vp run check:changed origin/main: format, lint, knip, typecheck, affected tests, and React Compiler validation all pass.
Checked in a running dev client with an isolated home, using the Cursor provider. With the switch off, $ lists only Personal Skill rows (no System Skill rows), and /create no longer matches Cursor's create-rule, create-skill, or create-hook.
Before: $ lists Cursor's built-in skills next to personal ones.
Settings: the new switch, turned off, under Chat > Advanced.
After: $ lists only personal skills.
Known limitation, unchanged by this PR: Cursor discovery labels everything under ~/.codex/skills as personal, including Codex's bundled .system/skill-creator and .system/skill-installer, so those two still appear with the switch off.
Implemented with Claude Opus 5.5 through Cursor in T3 Code.
Macroscope's review found this PR approvable — Adds an option to hide built-in skills from the / and $ menus while preserving existing visibility by default. The change is limited to menu presentation and can be reversed through settings.

Walkthrough
Adds a default-on setting for showing provider system skills. When disabled, the composer filters system skills from slash-menu suggestions and /skill searches. Chat settings includes a switch, reset action, and search entry.
Changes: Provider system skill visibility
Layer / File(s)
Summary
Add the visibility setting packages/contracts/src/settings.ts, apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts
The client settings schema and patch type include showSystemSkills. Chat settings exposes a switch and reset action, restores the default, and includes a settings search entry.
Filter provider system skills packages/client-runtime/src/providerSkills.ts, packages/client-runtime/src/providerSkills.test.ts
Adds a helper that excludes skills classified as system when the setting is disabled. Tests cover system, personal, project, and unscoped skills, including same-name personal skills.
Apply the setting to composer suggestions apps/web/src/components/chat/ChatComposer.tsx, apps/web/src/components/chat/useComposerMenuItems.ts
The composer passes the setting to the menu hook. The hook filters provider skills for slash-menu suggestions and /skill searches.

Explanation
The title "feat(web): option to hide built-in skills from the / and $ menus" matches the main change. The changeset adds a showSystemSkills setting, filters system-scoped provider skills from the / and $ menus in useComposerMenuItems, and adds the switch to Chat settings. The title is concise, uses a conventional commit prefix, and names the scope and the behavior.
Full details: Description check
Explanation
The description follows the template structure: Problem, Change, Scope and approval, and Verification are all present and filled in. The Problem section gives context and reproduction steps. The Change section lists the contract, runtime filter, and composer updates. The Scope and approval section argues the change is a focused configuration option for an existing capability, as the template requires. The Verification section names the focused tests, a check run, a manual check with observed results, and before/after screenshots, and it notes a known limitation. The template's agent attribution line is present. Minor gap: the Scope section does not link a triaged issue or maintainer approval, but it explains why none is needed for a focused configuration option, which the template allows.

- Line 296: Filter selectedProviderSkills for visible system-skill settings
before passing them to getProviderSkillsForSlashMenu, so a system skill cannot
remove a same-name personal skill before being hidden. Keep provider
slash-command deduplication based on the original slashMenuSkills, and add the
collision case to the existing skill-menu tests.
