Delegate implementation work to the OpenAI Codex CLI to save Claude tokens. Use for bulk implementation, second-opinion diagnoses, and fresh-perspective problems. Treat Codex as a peer senior engineer, not a reviewer. Runs codex exec non-interactively and returns only the outcome.
Use for reasoning-heavy phases — architecture decisions, debugging complex issues, algorithm design, tricky trade-offs. Think thoroughly, return a concise conclusion the orchestrator can act on.
