# record_run_step

**Record run step**

Record the current result of an agent-driven workflow run, in score order.

## Scope

- `generation.write` — Makes, edits, imports, shares and deletes media in the account.

## Behaviour

- **Writes**: Creates or changes items in the caller's own account.
- **Can delete or overwrite**: Can delete, overwrite, cancel or withdraw something the caller already has, so a host should confirm it.
- **Stays in the account**: Stays inside the caller's private Kuro account: any media provider it calls acts on Kuro's account, and the result is visible to no one else.

## Inputs

| Name | Type | Required | Details |
| --- | --- | --- | --- |
| `run_id` | string | yes | uuid |
| `step_id` | string | yes | matches ^[a-z][a-z0-9_]*$ |
| `result` | object or object (approved: true) | yes | — |

## Example call

A `tools/call` request with the required arguments only, each a placeholder read off the schema. Replace them before sending.

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "record_run_step",
    "arguments": {
      "run_id": "00000000-0000-4000-8000-000000000000",
      "step_id": "<step_id>",
      "result": {
        "text": "<text>"
      }
    }
  }
}
```

## Input schema

As the server sends it in `tools/list`:
