openclaw automations create "0 * * * *" --name "exercise-file-manifest" --command-argv '["python3","manifest.py","fixtures","state.json","--quiet-unchanged"]' --command-cwd "EXERCISE_ABSOLUTE_ROOT" --no-deliver

No job was created. No user scheduler was modified. Keep run history local and review any administrative permission before creating your own isolated job.
