Codex App: add a slash-menu filter to show only user-installed Skills

What variant of Codex are you using?

Codex App for Windows (26.707.9564.0, x64).

What feature would you like to see?

Please add a source/scope filter to the Codex App slash (/) candidate picker so users can choose to show only user-installed or personal Skills.

A useful minimum implementation would be a persistent option such as:

• All candidates (current behavior)
• My Skills only

A more complete implementation could expose separate filters or clearly labeled groups for:

• User-installed/personal Skills
• Workspace/project Skills
• Bundled/system Skills
• Plugin-provided Skills
• Artifact templates and prompts
• Built-in slash commands

Filtering the picker should affect discovery and autocomplete only. It should not disable, uninstall, or remove plugin capabilities, and hidden Skills should remain directly invocable by name.

Additional information

Current behavior

Typing / opens one combined candidate list containing personal Skills together with first-party runtime Skills, plugin Skills, and artifact templates. Examples include browser/computer-control entries, Documents/Spreadsheets entries, calendar or Notion entries, and document templates.

For users who install many specialized Skills, the personal entries become difficult to find. There is currently no obvious picker-only setting for showing just manually installed Skills. Disabling plugins is not an acceptable substitute because it removes useful capabilities and may not reliably hide every Skill supplied by installed packages.

Reproduction

1. Install several personal Skills.
2. Enable multiple Codex plugins or first-party runtime packages.
3. In the Codex App composer, type /.
4. Observe that personal Skills, plugin/runtime Skills, templates, and other candidates are mixed together.
5. Try to restrict the list to personal Skills without disabling or uninstalling plugins; no picker-level filter is available.

Expected behavior

Users should be able to select My Skills only, ideally as a remembered preference. The picker could also provide source badges and quick filter chips so the origin of every candidate is immediately visible.

Why this matters

The slash picker is the primary discovery surface for Skills. Mixing every source into one long list reduces discoverability for explicitly installed workflows and makes it difficult to distinguish user-owned Skills from bundled or plugin-provided entries. A visibility-only filter would solve this without sacrificing plugin functionality.

This report intentionally contains no account details, repository names, personal Skill names, local filesystem paths, logs, or other private information.
