# Codex (OpenAI) Agent Image
# =============================================================================
# Runs OpenAI's Codex agent through the official `codex` CLI, authenticated by a
# ChatGPT subscription via a mounted ~/.codex/auth.json — the parity analogue of
# the Grok path's mounted ~/.grok (no metered API key). Reuses the base image's
# roboco venv + uv + the RoboCo MCP gateway servers. The entrypoint renders
# ~/.codex/config.toml (the gateway) + the execpolicy deny rules + the per-role
# sandbox flag from the mounted mcp-config.json (see
# roboco.llm.providers.codex_cli_config) and runs the CLI headless. One runtime
# image serves every one-shot delivery role — role behaviour comes from the
# mounted system prompt / manifest / mcp-config, exactly as on the grok path.
#
# V1 scope: no interactive intake/secretary variant of this image exists (unlike
# grok's agent-grok-prompter / agent-grok-secretary) — Codex is one-shot delivery
# roles only for now.

# silent no-op) and verify the binary installed AND runs, so a broken install
# fails the build here, not at spawn. (curl/bash from the base.)
