Build, modify, and debug Ableton Live extensions written with the @ableton-extensions/sdk — TypeScript/Node.js code that runs in Live's Extension Host. Use this whenever the user is working on an Ableton Live extension: scaffolding a new one, adding context-menu actions or commands, navigating or mutating the Live Set object model (tracks, clips, devices, scenes, cue points), creating audio or MIDI clips, rendering or importing audio, showing modal webview dialogs or progress dialogs, grouping changes into a single undo step, or building/packaging an .ablx. Also use when you see `@ableton-extensions/sdk` imports, an `activate()`/`initialize()` entry point, a manifest.json with `minimumApiVersion`, `registerContextMenuAction`, `getObjectFromHandle`, `withinTransaction`, or files under an `extensions-sdk` folder. Trigger even if the user only says "Ableton extension" without naming the SDK.
