## About

# Goal Verifier

## When to Use

- User says **verify goal** or task matches this capability
- User says **confirm success** or task matches this capability
- User says **did I achieve this** or task matches this capability
- User says **check if done** or task matches this capability

## Workflow

1. Restate the original goal in one sentence.
2. List acceptance criteria (explicit or inferred from conversation).
3. Check each criterion: pass / fail / partial with evidence.
4. If any fail, invoke self-refine-loop or report gaps.
5. Only mark complete when all critical criteria pass.

## Integrations

- `self-refine-loop`
- `auto-tester`

## Error Handling

| Failure | Response |
|---------|----------|
| Goal undefined | Ask user to confirm goal before verifying. |
| False positive risk | Require evidence (file path, command output, or test result). |

## Gotchas

- Verification is read-only; do not mutate artifacts during checks.

## Example

**Input:** User request matching triggers above.
**Output:** Structured result per workflow with integrations invoked as needed.
