```

## Body

`text`, required, up to 8,000 UTF-8 bytes. The agent revises within about 30 seconds and the new version lands as a fresh card.

## Responses

`200 { ok: true }`. `409 invalid_action` if the card no longer accepts it.

## Frequently asked questions

### Which scope does this need?

`review:write`. A token without it gets `403` with `requiredScope` in the body. `GET /me` shows a token's scopes.

### Are responses cached?

No. Every response is `Cache-Control: no-store`, so what you read is current.
