-**Claude Code Dependency:** package.json includes @anthropic-ai/claude-code ^2.0.11
+**Claude Code:** Tracked via catalog/claude.json (not as npm dependency)
 
 **Use Case:** Ensures Claude Code and other AI agents have access to all necessary developer tools (ripgrep for code search, ast-grep for semantic search, jq for JSON parsing, git/gh for version control, etc.)
