# agent.budget.create

> Spawn a child agent with a scoped multisig sub-vault and a policy envelope. The operation is a saga — on any failure the partial state rolls back and the 10-min

Spawn a child agent with a scoped multisig sub-vault and a policy envelope. The operation is a saga — on any failure the partial state rolls back and the 10-min reaper cleans up anything in-flight.

## Auth

Caller's grant must include the `agent:budget:create` scope. Grants whose scope set is a superset of the required scope are accepted.

## Response examples

Success — agent provisioned and active:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "agent_principal_id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
    "vault_id": "b2c3d4e5-f6a7-8901-bcde-f12345678901",
    "policy_version": 1,
    "status": "active",
    "created_at": "2026-05-04T10:30:00Z"
  }
}
```

Saga still in-flight (poll until `status: "active"`):

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "agent_principal_id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
    "vault_id": "b2c3d4e5-f6a7-8901-bcde-f12345678901",
    "policy_version": 0,
    "status": "draft",
    "created_at": "2026-05-04T10:30:00Z"
  }
}
```

Insufficient scope:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32001,
    "message": "grant does not include scope agent:budget:create",
    "data": { "reason_id": "insufficient_scope" }
  }
}
```
