What it does
Long-form description, mapped skills, and a concrete usage example.
AGNTCY is broader than an A2A-only directory: it is an open-source infrastructure project for discovery, identity, messaging, and observability across agent frameworks. It matters because it explicitly positions A2A and MCP as part of a larger interoperable agent infrastructure stack.
