A SKILL.md that guides an AI coding agent through reviewing custom 404 error pages. It covers checking that a custom page exists with helpful navigation, that the server returns a real HTTP 404 status, and that the final browser-facing markup is validated rather than just the framework source.
Use it when you want an agent to audit 404 pages for user retention and correct status codes during code review.
Use it to
- Review 404 templates and rendered HTML
- Verify missing routes return HTTP 404, not 200
- Check for search and navigation recovery paths
- Explain soft-404 indexing problems
- Flag exact markup issues in shared components
