How to pass it

Publish an Agent Skills index at /.well-known/agent-skills/index.json describing what an agent can accomplish here, so it need not read your docs to find out.

Check your own site

Free, no signup, same endpoint that produced every grade on the leaderboard:

curl "https://index.percall.dev/api/score?url=https://your-site.example"

It returns the letter grade and every check by name with pass/fail. The $0.05 call at POST /api/audit adds why each one failed and a snippet with your origin already in it.

The rest of the checklist

6 more 2026 checks, and 13 from the other generation.
