## Definitions

### `dev.knotless.updateRepo`

**Type**: `procedure`

Rewrites the repository's dev.knotless.repo record with a new description, new links or a new default branch, any of them, as `knotless describe` does. The default branch must be one of its branches, once it has any. Only its owner, logged in to this appview's web pages, can: the appview writes with the session it keeps for that account, which the pages' session cookie names.

#### Input

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `defaultBranch` | `string` | No | The branch its HEAD names, without refs/heads/. Left as it is when absent. |
| `description` | `string` | No | What the repository is; empty drops it. Left as it is when absent. |
| `links` | `array` | No | The links its pages show, in order, each an http or https address: its website first. Replaces those it had; empty drops them. Left as they are when absent. |
| `repo` | `string` (at-uri) | Yes | The repository's dev.knotless.repo record, as dev.knotless.getRepo takes it. |

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `defaultBranch` | `string` | No | The branch its HEAD names now. |
| `description` | `string` | No | What it says it is now; absent when it says nothing. |
| `links` | `array` | No | The links its pages show now; absent when there are none. |

#### Errors

- **NotFound**: No such repository.
- **InvalidRequest**: None was given, the description is too long, a link is not an http or https address or there are too many, or the repository has no such branch.
- **AuthenticationRequired**: No account is logged in to the pages, or its session has ended.
- **Forbidden**: The account logged in is not the repository's owner.
