How ReachCheck scores public agent access
An open, versioned checklist; unknown is not failure and optional files are not mandatory.
Eleven explicit checks: HTTPS 8, response 12, readable HTML 18, robots policy 12, metadata 8, structured data 8, llms.txt 8, docs 8, OpenAPI 8, agent card 4, support handoff 6. Score is passed weight divided by measured weight. Unknown checks are excluded; below 50% coverage no score is issued. Optional discovery files are not mandatory. No login, purchase, JavaScript rendering or live API execution is tested.
