Plugin skills not appearing in slash command autocomplete

Summary

Skills installed via plugins (e.g., example-skills@example) do not appear in the / slash command autocomplete list in the Claude Code CLI.

Environment

• Claude Code version: 2.1.87
• Platform: macOS (darwin 25.3.0)
• Shell: zsh

Steps to Reproduce

1. Install a plugin with skills via enabledPlugins in settings.json:

``json
{
"enabledPlugins": {
"example-skills@example": true
}
}
``

1. Verify the plugin is installed in ~/.claude/plugins/installed_plugins.json and skills exist at ~/.claude/plugins/cache/<org>/<plugin>/<version>/skills/
2. Open Claude Code CLI and type /
3. Observe that plugin skills (e.g., example-skills:plan, example-skills:gemini) do not appear in the autocomplete list

Expected Behavior

Plugin skills should appear in the / slash command autocomplete, similar to how locally defined commands in ~/.claude/commands/ appear.

Actual Behavior

Plugin skills are completely absent from the autocomplete list. However, they do work correctly when invoked programmatically within a conversation (they appear in the system's available skills and can be called via the Skill tool internally).

Additional Context

• Skills stored in ~/.claude/commands/ (local markdown files) correctly appear in autocomplete
• The autocomplete appears to only read from the commands/ directories, not from ~/.claude/plugins/cache/
• Typing /example- or the full skill name does not produce any autocomplete suggestions
• The skills themselves function correctly once a session is active

Workaround

Creating stub .md files in ~/.claude/commands/ allows them to appear in autocomplete, but this is a manual workaround and disconnects the stub from the actual plugin skill.
