Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| meta_horizon_developer_statusC | Return latest collection health for one application. app_id: target application ID. snapshot_dir: directory holding that application's snapshots. |
| meta_horizon_developer_collectA | Collect allow-listed aggregate GraphQL Queries into a new snapshot. Requires profile_dir because it drives an authenticated browser. Fails immediately with ProfileBusyError when another process already holds that profile. |
| meta_horizon_developer_latest_snapshotB | Return latest snapshot metadata and collection health, not the large payload. |
