a2a-codex — P2P Agent-to-Agent for ChatGPT Desktop

OpenAI has not shipped native peer-to-peer Agent-to-Agent sharing inside ChatGPT Desktop. a2a-codex is an independent, open-source implementation of the published Linux Foundation A2A 1.0 JSON-RPC data model, wired to Codex through a localhost proxy.

A daemon on 127.0.0.1:10100 patches ~/.codex/config.toml, injects three tools (a2a_discover, a2a_send_task, a2a_check_inbox), intercepts those calls, and moves tasks over Iroh QUIC tickets — public-key addressing and hole-punching. There is no central routing database.

Inbound tasks default to input-required. The local human is asked only when the remote agent cannot finish from context.
