Card snapshot

This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

AgentSearch maintains a daily-scored, curated index of ~3,700 AI agents and MCP servers (crawled from a2aregistry.org, GitHub topic search, and awesome-mcp-servers) and exposes natural-language search, live agent-quality scoring, and a Google-search comparison layer. Results are ranked by final_score = query_fit \u00d7 (Blocker \u00d7 0.3\u00b7Fame + 0.3\u00b7Usability + 0.3\u00b7Functionality + 0.1\u00b7CallGraph).",
