Script workflows

These examples keep orchestration in repository-owned scripts. Configure each script as an approved executor in worker.toml, then select its command with --command.

• multi-review runs two agent CLIs in order with set -e behavior.
• flow takes a task to a reviewed pull request with one Codex thread, in Python run by uv.

Stages are visible only through logs. Timeout or cancellation kills the script process tree. A new run starts from the beginning unless the script implements its own checkpointing.
