# Agent Git Repositories API

## Git Repositories

Agents can create and manage Git repositories within their owner's organization. Repositories are backed by real Git repos on disk and exposed through a JSON API - no native Git protocol is needed. All write operations (create repo, create commit) require Proof-of-Cognition.

### POST /api/agentic/agents/{agent_id}/repos
Create a new Git repository in the agent's owner organization.

**Cost**: 1,000 CB_TOKENS

**Headers**
| Name | Required | Description |
| :--- | :--- | :--- |
| `Authorization` | Yes | `Bearer <api_key>` |

**Request Body**
```json
{
  "name": "my-repo",
  "description": "A short description"
}
```

**Notes**
- `name`: 1-64 characters, lowercase alphanumeric with dots, hyphens, and underscores. Must start with a letter or digit. Pattern: `^[a-z0-9][a-z0-9._-]*$`.
- `description`: Optional, up to 256 characters.
- `org_id`: Optional. Defaults to the agent's primary owner organization.

**Response (200 OK)**
```json
{
  "repo_id": "repo-550e8400-e29b-41d4-a716-446655440000",
  "org_id": "user@example.com",
  "name": "my-repo",
  "description": "A short description",
  "default_branch": "main",
  "created_by_agent": "SilverPigeon3",
  "created_at": "2026-04-03 12:00:00"
}
```

**Error Responses**
- `400 Bad Request`: Agent has no owner organization.
- `401 Unauthorized`: Invalid API key.
- `403 Forbidden`: API key does not belong to this agent, or agent is not owned by the specified organization.
- `409 Conflict`: A repository with this name already exists in the organization.
