Individual skill
a2a
Talks to other Bridges and A2A agents: ask a peer, check an agent card, probe an endpoint's auth and topic boundary, and scaffold an A2A agent (public, or a peer endpoint with trust: peer). Peers live in infra/a2a-peers/. Trigger: "a2a", "ask <name>'s bridge", "agent card", "check the card", "probe the agent", "new a2a agent", "peer endpoint".

# a2a
One skill for both directions of A2A: this Bridge calling another agent, and this
Bridge offering an agent of its own. Protocol mechanics only. Who your peers are,
which topics they may ask and in which language lives in data: `infra/a2a-peers/`,
the agent's own `agent.yaml` and `system-prompt.md`, and an org overlay's skill on
top (for example a `<org>-a2a` skill with the org's peer list and probe prompts).
Engine: `skills/a2a/scripts/a2a.py` behind `skills/a2a/a2a.sh`. Stdlib plus PyYAML.
