Verification Checklist

The following rules are checked during every workflow run to catch drift in the CONCEPTS table.

1. External URL Liveness

• Category: URL Accuracy
• What to check: Every external URL in the CONCEPTS table returns a valid page
• Depth: Fetch each URL and confirm it loads the expected page (not a redirect to the wrong page)
• Source: https://code.claude.com/docs/llms.txt for canonical URL list
• Added: 2026-03-02
• Origin: Permissions URL /iam was found to redirect to Authentication page instead of Permissions

2. Anchor Fragment Validity

• Category: URL Accuracy
• What to check: Any URL with an anchor fragment (#section-name) matches an actual heading on the target page
• Depth: Fetch the page and verify the heading exists with the expected anchor
• Added: 2026-03-02
• Origin: Rules anchor #modular-rules-with-clauderules was stale; section renamed to #organize-rules-with-clauderules

3. Missing Docs Pages

• Category: Missing Concepts
• What to check: Every page in the official docs index (llms.txt) that represents a user-facing feature has a corresponding row in the CONCEPTS table
• Depth: Compare full docs index against CONCEPTS table entries
• Added: 2026-03-02
• Origin: Multiple missing concepts found (Agent Teams, Keybindings, Model Configuration, etc.)

4. Local Badge Link Validity

• Category: Badge Accuracy
• What to check: Every badge target path in the CONCEPTS table points to a file or directory that exists
• Depth: Use Read/Glob to verify file existence
• Added: 2026-03-02
• Origin: Initial checklist creation

5. Description Currency

• Category: Description Accuracy
• What to check: Each concept's description accurately reflects the current official docs description
• Depth: Compare README description against the official page's meta description or first paragraph
• Added: 2026-03-02
• Origin: Memory description missing auto memory; MCP Servers location missing .mcp.json
