Summary

  • Adds @vercel/agent-readability package for AI agent detection in middleware
  • Detected agents get markdown responses instead of HTML for better AI consumption
  • Non-existent docs URLs return helpful not-found markdown with discovery links
  • Accept header content negotiation continues to work as before

Matches the geistdocs template (vercel/geistdocs#58). Uses the same shared package as vercel/front#65649.

Test plan

  • AI agent hitting a valid docs URL gets markdown rewrite
  • AI agent hitting a non-existent docs URL gets not-found markdown
  • Normal browser requests unaffected
  • Build passes
