### manage_kv example

  "action": "set",
  "key": "counter:requests",
  "value": 42,
  "ttl": 3600
}
```

## Custom Domains

| Tool | Description |
|------|-------------|
| `configure_custom_domain` | Add, list, check status, verify, or remove custom domains. Actions: `add`, `list`, `status`, `verify`, `remove`. |

## Hackathon

These tools are listed whenever any hackathon's submission window is open. Multiple hackathons can be open simultaneously; tools that target one require an explicit `hackathon_slug`. See [Hackathon](/hackathon).

| Tool | Description |
|------|-------------|
| `prep_and_submit_hackathon_entry` | Two-step flow. `action: "prep"` resolves the hackathon from your `submission_code` and returns its `field_schema` plus a `next_call` template — a fully-formed example `submit` invocation with a placeholder per field. `action: "submit"` sends the confirmed `data` (use `matched.slug` from prep as `hackathon_slug`). First submission also needs `submission_code`. Pass `app_id` (from `manage_app` `list`) so automated scoring can award feature points and judges can verify your app. |

## Feedback & Documentation

| Tool | Description |
|------|-------------|
| `submit_suggestion` | Submit feedback, bug reports, or feature requests. |
| `butterbase_docs` | Read documentation by topic. |
