Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 handoff-lint-scorer-b63e5549 -d '<json body>'
```

Example prompt: Score this handoff message I'm about to pass to the next agent — it says 'Task complete: refactored the auth module, tests pass, ready for deployment' — and tell me what verification evidence, constraints, ownership details, or next steps I'm missing.

## When to prefer this

Use this endpoint at every handoff point in a multi-agent pipeline to ensure continuity and completeness. Prefer it when you need structured feedback on what is missing from a handoff rather than a simple pass/fail check. Ideal for pipelines where agents hand off partially-completed tasks and the next agent needs clear ownership, constraints, and verification evidence to proceed safely.

## Known failure modes

- Missing or malformed 'input' field returns a 400 validation error
- Body not wrapped in expected HTTP-typed input object causes schema rejection
- Empty handoff text may return a low score with all categories flagged as missing
- Payment not settled (x402) results in 402 Payment Required response before processing

## How this service works

POST handoff text; get a score plus missing pieces (verification, constraints, ownership, next steps, risks). Use every handoff in a multi-agent run — pay per call. Field guide: pack demo-notes-v1.

## Output

A numeric quality score plus a structured list of missing elements categorized into verification evidence, constraints, ownership, next steps, and risks — helping the agent improve the handoff before passing control.
