[BUG] Built-in slash commands hidden from autocomplete when too many skills are installed

[zhaozuowu1]

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

Built-in slash commands (like /model, /help, /doctor, /cost) do not appear in the autocomplete dropdown when typing /. Only custom skills from the ~/.claude/skills/ directory are shown.

  The commands still work when typed manually (e.g., typing /model and pressing Enter executes correctly), but they are completely hidden from the autocomplete list.

What Should Happen?

Built-in commands should always appear in the autocomplete list, ideally with higher priority than custom skills.

Steps to Reproduce

1. Install multiple skills in ~/.claude/skills/ directory (I had ~50 skills)
     2. Start Claude Code in interactive mode
     3. Type / to trigger autocomplete
     4. Observe that only custom skills appear, built-in commands like /model, /help are missing

Bug Report: Built-in slash commands hidden from autocomplete when too many skills are installed

  Environment
  - Claude Code version: 2.1.25
  - Install method: native
  - OS: macOS Darwin 23.4.0

  Description
  Built-in slash commands (like /model, /help, /doctor, /cost) do not appear in the autocomplete dropdown when typing /. Only custom skills from the ~/.claude/skills/ directory are shown.

  The commands still work when typed manually (e.g., typing /model and pressing Enter executes correctly), but they are completely hidden from the autocomplete list.

  Steps to Reproduce
  1. Install multiple skills in ~/.claude/skills/ directory (I had ~50 skills)
  2. Start Claude Code in interactive mode
  3. Type / to trigger autocomplete
  4. Observe that only custom skills appear, built-in commands like /model, /help are missing

  Expected Behavior
  Built-in commands should always appear in the autocomplete list, ideally with higher priority than custom skills.

  Actual Behavior
  Autocomplete list only shows custom skills. Built-in commands are completely hidden from the dropdown.

  Workaround
  Temporarily moving/removing the ~/.claude/skills/ directory restores built-in commands in autocomplete:
  mv ~/.claude/skills ~/.claude/skills.backup

  Diagnostic Output
  /doctor shows no errors related to this issue:
  - Search: OK (bundled)
  - All other diagnostics pass

  Suggested Fix
  - Increase the autocomplete dropdown limit
  - Or prioritize built-in commands to always appear first
  - Or add a separate section for built-in commands vs custom skills

This is a new issue. It's not that the skill plugin doesn't appear in the slash command. The problem is that when you input the "/config /model" command, there is no auto-completion and it is not displayed in the slash command either.

Similar issue faced here:

Screenshot

Elaboration: Commands are working.
To get /resume one would have to space and escaped out of the input params for /skill-creator for instance

Current Version : v2.1.34 (previously v2.1.32)

Attempted Fix :

reran curl -fsSL https://claude.ai/install.sh | bash to update to v2.1.34 and was still failing.
