exec turn failed: {error}

Error message

exec turn failed: {error}

What it means

Terminal failure path for `codewhale exec`: the completed turn's summary carries a non-empty error. The exit code was computed from error_category — this bail! is the historical exit-1 path kept for genuine task failures, so supervisors see exit 1 rather than a retryable-infrastructure code.

Solutions

1. Read the embedded {error} text from the turn summary
2. Fix the task-level cause (bad prompt, tool failure, etc.)
3. Re-run the exec command
