[Bug] User-invocable skills not appearing in tab completion after commands/skills merger

Bug Description

After the Jan 24, 2026 commands/skills merger, skills marked with user-invocable: true are not
appearing in slash command tab completion.

Steps to reproduce:

1. Create a plugin with skills in skills/ directory
2. Add user-invocable: true to skill frontmatter
3. Install plugin via marketplace
4. Type /plugin-name: and press Tab

Expected behavior:
Skills with user-invocable: true appear in tab completion menu (as documented in the merger
announcement)

Actual behavior:
No completions shown. User must type full skill name manually or create duplicate files in
commands/ directory.

Environment:

• Claude Code version: [current as of Jan 27, 2026]
• Platform: Linux

Workaround:
Maintain duplicate command files in both skills/ and commands/ directories (observed pattern in
community marketplace plugins)
