## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability interrupted-task-recovery-06467025 -d '<json body>'
```

Example prompt: My agent was partway through a multi-step task and got interrupted — can you plan a safe, idempotent resumption from the last checkpoint so we don't re-execute steps that already completed?

## When to prefer this

Use this endpoint when an agent task has been interrupted partway through execution and you need a safe, bounded plan to resume without repeating already-completed steps or causing duplicate side effects. Prefer this over manual state inspection when idempotency guarantees are critical, especially for tasks involving payments, external API calls, or stateful operations where replaying completed steps would cause harm.

## Known failure modes

- Checkpoint data is missing or malformed, preventing recovery plan generation
- Task state is ambiguous and idempotency cannot be guaranteed
- Requested resumption scope exceeds defined task boundaries
- Checkpoint is too stale to produce a valid resumption plan
- Input schema is incomplete, resulting in rejection of the recovery request

## How this service works

Plan bounded idempotent resumption from a checkpoint

## Output

A structured resumption plan indicating which steps have already been completed, which remain, and how to safely re-enter the task from the last checkpoint in an idempotent and bounded manner — ensuring no side effects are duplicated and execution stays within defined scope.
