Next steps

• Choose the model for each stage of the loop by editing AGENT_MODEL, ANALYSIS_MODEL, EVAL_GENERATION_MODEL, JUDGE_MODEL, and HALO_MODEL near the top of the notebook.
• Create your own traces to test the agent.
• Decide how much of the final path should remain reviewed versus automated: you can stop at a developer-reviewed PR, or wire the handoff into a system that opens, merges, and deploys changes automatically.
• Pass the generated codex_handoff.md file under ARTIFACT_DIR to Codex, inspect the harness changes it proposes, and rerun the same eval suite against the updated harness.
