Skill instructions
Codex agent provider NanoClaw runs agents in a long-lived poll loop inside the container. The backend is selected with AGENTPROVIDER (claude | opencode | codex | mock). Trunk ships with only the claude provider baked in. This skill copies the Codex provider files in from the providers branch, wires them into the host and container barrels, updates the Dockerfile to install the Codex CLI, and rebuilds the image. The Codex provider runs codex app-server as a child process and speaks JSON-RPC over stdio. That gives it native session resume, streaming events, MCP tool access, and thread/compact/start compaction — same feature bar as the Claude Agent SDK, without the Anthropic-only lock-in. Install Pre-flight If all of the following are already present, skip to Configuration: - src/providers/codex.ts - container/agent-runner/src/providers/codex.ts - container/agent-runner/src/providers/codex-app-server.ts - container/agent-runner/src/providers/codex.factory.test.ts - import './codex.js'; li
