# Timeline / List TimelineAssets

Search the project AssetDatabase for `TimelineAsset` (.playable) assets and report each one's path, GUID, track count, and computed duration.

## Inputs

- `includeTrackCount` (bool, default true) — when true, load each asset to count its output tracks; when false, skip loading (faster, no counts).

## Behavior

Runs `AssetDatabase.FindAssets("t:TimelineAsset")`, resolves each to a path, and (optionally) loads it for track count + duration. Read-only. Runs on the Unity main thread.

## How to Call

```bash
unity-mcp-cli run-tool timeline-list --input '{
  "includeTrackCount": false
}'
```

> For complex input (multi-line strings, code), save the JSON to a file and use:
> ```bash
> unity-mcp-cli run-tool timeline-list --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-tool timeline-list --input-file - <<'EOF'
> {"param": "value"}
> EOF
> ```


### Troubleshooting

If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead.
Read the /unity-initial-setup skill for detailed installation instructions.

## Input

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `includeTrackCount` | `boolean` | No | If true (default), load each asset to report its track count and duration; if false, skip loading. |
