> Resume restarts a paused Agent in every seat it holds, with its Memory, Mandates and Limits unchanged.

Resume restarts a paused [Agent](/business/nouns/agent) in every seat it holds, with its [Memory](/business/nouns/memory), [Mandates](/business/nouns/mandate) and [Limits](/business/nouns/limit) unchanged.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `agent` | [Agent](/business/nouns/agent) | Yes | The paused Agent. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `agent` | [Agent](/business/nouns/agent) | Yes | The working Agent. |

## Effects
- Emits [`Agent.resumed`](/business/events/Agent.resumed).
- Performed by the [Founder](/agents/founding/founder).
- Two-way: it runs at once, in the `try`, `send` and `do` modes.
- Releases held Actions into what remains of their delay windows, and works the queued Tasks oldest first.

## 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. | [Agent.resume](/business/nouns/agent/resume) |

## 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`. |
