# Timeline Skills

Create and modify Unity Timelines.

## Guardrails

**Mode**: Full-Auto required

**DO NOT** (common hallucinations):
- `timeline_create_animation` / `timeline_add_track` do not exist → use the typed track skills: `timeline_add_animation_track`, `timeline_add_audio_track`, `timeline_add_activation_track`, `timeline_add_control_track`, `timeline_add_signal_track`
- `timeline_add_keyframe` does not exist → Timeline uses clips, not direct keyframes; use `timeline_add_clip`
- `timeline_set_duration` sets the Timeline asset duration, not individual clip duration

**Routing**:
- For Animator parameters/states → use `animator` module
- For runtime animation playback → use `editor_play` or write C# via `script` module
