Ready to inspect

Run validation to inspect required fields, distinguish agent and protocol versions, summarize endpoints and auth, and surface capabilities.

Scope: static JSON and A2A 1.0 profile checks. This tool does not fetch remote URLs, call an agent endpoint, execute MCP tools, or cryptographically verify signatures.
