# Helper reference index

Use a helper only when it expresses the task's policy. Preserve candidate or work identity outside helper results that may omit failed agents.

- Read [quality helpers](quality-helpers.md) for `verify()` or `judgePanel()`.
- Read the [retry helper](retry-helper.md) for `retry()`.
- Read [specialized helpers](specialized-helpers.md) for `completenessCheck()`, `loopUntilDry()`, `gate()`, or `checkpoint()`.

Runtime agent retries repeat recoverable execution failures; helper attempts are new semantic calls. Bound both layers and ledger exhaustion.
