# Ultra-fast development

> Multitask with priority-aware, edit-scoped verification.

Run independent development tasks concurrently:

```bash theme={null}
arka ultra_fast --iterations 3 \
  --task 'ui|1|frontend_loop review app.png|src/components|pytest tests/test_ui.py' \
  --task 'docs|0|update_docs|docs|pytest tests/test_docs.py'
```

Task format is `name|priority|build-command|edited-paths|test-command`.

* Priority `1`: run its test after every iteration in which one of its paths changed.
* Priority `0`: run its test only once after all iterations, and only if its paths changed.
* Unedited tasks are never tested.
* Priority mode is enabled by default; use `--no-priority` to disable it.
* Use `--auto-priority` when every task/prompt must be treated as priority `1`.

The scheduler reports every task, exit code, and whether it was edited. Keep
build commands independent and review generated changes before deployment.
