## Description

Use when you need Codex to coordinate multiple agents through Agent Relay for peer-to-peer messaging, lead/worker handoffs, or shared status tracking across sub-agents and terminals.

# Agent Relay

Use this skill when Codex needs real-time coordination across multiple agents. It gives Codex a repeatable workflow for:

- connecting to an Agent Relay workspace
- spawning relay-aware workers
- sending direct messages, channel updates, and thread replies
- keeping lead and worker state synchronized through ACK, STATUS, BLOCKED, and DONE signals

Relay fills the peer-to-peer gap in Codex sub-agent workflows. Codex can spawn and collect worker results, but Agent Relay gives those workers a shared message bus so they can talk to the lead and to each other.

## Auto-setup

On first activation, this skill auto-configures Codex by running `scripts/setup.sh`. This adds the Agent Relay MCP server to `.codex/config.toml`, enables hooks, installs `hooks.json`, and copies the `relay-worker.toml` agent definition. No manual setup is required after installing the skill.

## Startup protocol

Every relay-connected Codex agent must complete these steps IN ORDER before substantive work:

1. **Set up a workspace.**
   - If `RELAY_WORKSPACE_KEY` is set in the environment, call `set_workspace_key` with that key.
   - If only the legacy `RELAY_API_KEY` alias is set, treat it as the same workspace key.
   - If no key is available, call `create_workspace` to auto-create one. This returns a workspace key, save it for workers.

2. **Register as an agent.** Call `register_agent` with your agent name and `type: "agent"`. Use `RELAY_AGENT_NAME` from the environment if set, otherwise derive a name from the task context (e.g., `lead`, `auth-worker`).
