## 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 nock-decide-go-no-go-decision-engine-904d7552 -d '<json body>'
```

Example prompt: We're about to ship the new checkout flow without legal sign-off — should we go ahead, wait, or kill it? My options are: ship now, wait for legal, or roll back.

## When to prefer this

Use /decide when you already have a specific proposed action or candidate options and need a structured go/no-go/wait judgment with a risk and reason. Prefer this over /next (which generates the next action from scratch) and /brief (which compresses messy input). Ideal when an agent or workflow needs a gatekeeping decision before committing to an irreversible step.

## Known failure modes

- Empty or ambiguous 'text' field yields a low-confidence or malformed decision
- Options array with contradictory or unclear items may produce an unexpected pick
- Very long or unformatted input text may need /brief pre-processing first
- Network or payment failure returns a 402 or 5xx with no decision payload
