URL: /business/nouns/risk/update · Id: `verb:Risk.update` · Call: `await $.Risk.update({ … })` (SDK) or the `do` tool at `https://api.sb/mcp`. Inputs says what to pass, Outputs what returns, When it waits who approves.

> Changes the given properties of a Risk.

Update changes the given properties of a [Risk](/business/nouns/risk). It is inherited: every [Noun](/business/nouns/noun) has `get`, `list`, `create`, `update` and `delete`.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | `string` | Yes | The id of the Risk. |
| `scope` | `string` | No | Whose Risk it is: `startup` or `portfolio`, for exposure shared across siblings. |
| `likelihood` | `integer` | No | How likely it is within a year, from 1 (rare) to 5 (expected). |
| `impact` | `integer` | No | How much harm it does if it happens, from 1 (minor) to 5 (ends the Startup). |
| `treatment` | `string` | No | The chosen response: `treat`, `accept`, `transfer`, or `avoid`. |
| `owner` | [Role](/business/nouns/role) | No | The Role that owns the Risk and its next review. |
| `reviewBy` | `date` | No | When the owner next scores it again. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `risk` | [Risk](/business/nouns/risk) | Yes | The Risk. |

## Effects
- Emits `Risk.updated`.
- Two-way: `try`, `send`, `do`.

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Risk.update](/business/nouns/risk/update) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
