### Description (declared)

A2A v1.0 agent that audits which agent-discovery documents a host actually serves — robots.txt, llms.txt, openapi.json, the .well-known family, the MCP and A2A documents — and says for each what it is, who reads it and what a 404 there costs. It also validates a pasted llms.txt or A2A agent card against the spec and drafts an llms.txt from a sitemap. Deterministic, no key.
