Generate cross-reference graph showing relationships between design documents. Use when visualizing doc dependencies, finding related docs, or understanding documentation structure.
Validate design doc structure and frontmatter. Use when checking design docs for compliance, ensuring proper formatting, or verifying metadata before commits.
Comprehensive quality audit for CLAUDE.md context files. Use when performing thorough quality checks, preparing for releases, ensuring context efficiency, or verifying token optimization.
Style rules for LLM context files (CLAUDE.md, AGENTS.md and their .local variants). Fires automatically when these files are opened. Enforces on-demand loading patterns, proper @-reference syntax and lean context structure.
Split large CLAUDE.md into child files. Use when context files exceed word limits, are too verbose, or cover multiple distinct topics that should be separate.
Validate CLAUDE.md structure, formatting, and quality. Use when checking context files for compliance, ensuring proper structure, or verifying before commits.

Compares design document versions across git commits, branches, or tags to track evolution and understand changes over time.
This skill compares document versions by validating git references, loading document content from different versions, performing line-by-line or semantic diffs, analyzing changes for significance, and generating comprehensive comparison reports with metrics and highlights.
Compare with main branch:
/design-docs:design-compare observability.md --ref=main
Compare two commits:
/design-docs:design-compare doc.md --from=abc123 --to=def456
Semantic comparison:
/design-docs:design-compare doc.md --ref=v1.0.0 --format=semantic

ERROR: Git reference not found: {ref}
Valid references:
- Commit hash: abc123
- Branch name: main, feature-branch
- Tag name: v1.0.0
Check: git log or git branch -a
ERROR: Document not tracked by git
Document: {doc}
Ensure document is committed before comparing versions.
INFO: No changes between versions
Document: {module}/{doc}
References: {from} → {to}
The document is identical in both versions.
