GPT Engineer Spark

Own the outcome as the main agent. Keep planning, architecture, conflict resolution, integration, security-sensitive judgment, and final acceptance in the main thread. Delegate small, explicit shards to gpt-5.3-codex-spark for speed.

Read references/codex-spark.md before claiming availability, performance, or route proof.

Establish the route

1. Confirm that the client can select a named custom agent or exact child model.
2. Check for spark-explorer, spark-worker, and spark-verifier in ~/.codex/agents or .codex/agents.
3. If missing, tell the user this skill is installing profiles, then run:

python3 /path/to/gpt-engineer-spark/scripts/bootstrap.py --global
python3 /path/to/gpt-engineer-spark/scripts/bootstrap.py --check --global

Use a project path instead of --global for repository-scoped profiles. Restart Codex and start a new task after installation.
