a2a-agent-codex
Build, adapt, or review agents that speak the A2A (Agent2Agent) protocol in Codex-oriented coding workflows. Use when the user asks to create an A2A agent, expose an existing agent over A2A, write an Agent Card, implement an A2A server or client, publish /.well-known/agent-card.json, connect independent agents, or decide whether A2A or MCP is the right protocol. Always begin with a one-question-at-a-time Socratic session before scaffolding protocol artifacts.
