Global skills registered N times — duplicates in slash command autocomplete

Description

Custom skills in ~/.claude/skills/ appear multiple times in the / autocomplete. Each skill is duplicated exactly as many times as there are projects with a local .claude/settings.local.json.

Environment

• Claude Code version: 2.1.92
• OS: macOS 14.6 (Darwin 24.6.0)
• Interface: JetBrains (WebStorm) plugin

Steps to Reproduce

1. Have custom skills in ~/.claude/skills/ (e.g. agent-commit, commit, etc.)
2. Have multiple projects each with a .claude/settings.local.json
3. Open Claude Code and type / to open the autocomplete

Expected Behavior

Each skill appears once in the autocomplete.

Actual Behavior

Each skill appears 6 times. The duplication count (6) correlates exactly with the number of projects that have both a ~/.claude/projects/<project>/ entry and a local .claude/settings.local.json:

• ~/.claude (global)
• ~/WebStormProjects/omodo-ai/.claude/
• ~/WebStormProjects/tidywl/.claude/
• ~/WebStormProjects/tidywl-site/.claude/
• ~/Documents/Documents/dev/code-scratchpad/.claude/
• ~/Documents/Documents/dev/range/.claude/

Investigation

• ~/.claude/skills/ contains exactly 9 skill directories, all real directories (no symlinks)
• No other skills/ directories exist anywhere under ~/WebStormProjects or ~/Documents
• No project-level CLAUDE.md files register slash commands
• 11 total project contexts in ~/.claude/projects/, 6 with local settings
• Issue persists after full computer reboot

Suspected Cause

Global skills (~/.claude/skills/) appear to be registered once per project that has a settings.local.json, rather than being loaded once and deduplicated. This results in N registrations of every global skill where N = number of projects with local settings.
