# What a preset would change

`POST /v1/agents/{agent_id}/policy-preset/preview`

## Request

- Base URL: `https://api.1claw.co`
- URL: `https://api.1claw.co/v1/agents/{agent_id}/policy-preset/preview`
- Auth: HTTP bearer

Compiles a preset against this agent and reports which fields it would
**widen** — loosen relative to what the agent can already do.

Widening detection errs toward flagging: a false positive costs one extra
approval, a false negative is a limit raised without review. Enabling a
capability widens; disabling does not. Raising a cap widens; setting a
first cap does not, because absent means unlimited.

## Path parameters

- `agent_id` string, uuid, required

## Request body

- object
  - `preset` string, required

## Response `200`

Proposal

  - `requires_guardrail_approval` boolean
  - `explanation` string

## Other responses

- `403`: Insufficient permissions
