Codex agent provider

Shortcut: pnpm exec tsx setup/index.ts --step provider-auth codex performs this whole install (manifest-driven from the providers branch: files, barrels, CLI manifest entry, image rebuild) plus auth in one command. The steps below are the same operations, for agent-driven or manual application.

NanoClaw selects each group's agent backend from container_configs.provider (default claude). This skill installs the Codex provider: copy the payload from the providers branch, append one import to each of the three provider barrels, add the pinned Codex CLI to the container manifest (container/cli-tools.json), rebuild, then run the vault auth walk-through.

The provider runs codex app-server as a child process speaking JSON-RPC over stdio: native streaming, MCP tools, server-side conversation history (the continuation is a thread id, no on-disk transcript). Credentials are vault-only: OneCLI serves a sentinel auth.json stub into the container and swaps the real ChatGPT token or API key on the wire — no key in .env, nothing readable in the container.

The mechanical steps under Install carry nc: directive fences: an agent reads the prose and applies them, and a parser can apply them deterministically from the same document. Every directive is idempotent, so the whole skill is safe to re-run; anything a parser can't apply falls back to the prose beside it.

Install

Pre-flight

Requires src/project-doc-compose.ts on trunk. If it is missing, stop and tell the operator to run /update-nanoclaw first.

Check whether the payload is already wired (a prior apply, or a trunk that still carries it). All of these present means installed — skip to Authenticate:
