task

Retry policy for this task · { max_attempts, backoff_ms, backoff_strategy, backoff_max_ms, jitter, on_codes }. Retries run BEFORE on_error sees anything — the catch handles the last error only (spec/05-errors.md §Retry policy).

Contract and implementation

This page projects the named specification revision. Check released engine status and the validation workflow before running a file. An optional field is not evidence that every engine supports every value. Canonical identity: language:word:retry. Spec revision: 5c40ba456c53. How documentation stays connected.
