Using the pre-provided tone.min.js (global Tone), build a playable piano keyboard controlled by mouse and computer keys that synthesizes notes with an ADSR envelope and visual key feedback.

The user wants me to create a single-page web app with a playable piano keyboard using the pre-provided tone.min.js library. I need to: 1. Create a self-contained index.html file with CSS and JS inline 2. Use tone.min.js for audio synthesis with ADSR envelope 3. Support both mouse and keyboard input 4. Add visual feedback for key presses Let me first check if tone.min.js exists in the current directory.
{"command":"ls -la /tmp/ws/"}total 344 drwxr-sr-x. 2 node node 25 Aug 1 20:27 . drwxrwsrwx. 3 root node 16 Aug 1 20:27 .. -rw-r--r--. 1 node node 349169 Aug 1 20:27 tone.min.js

Good, tone.min.js is present. Now I'll create a self-contained index.html file with: 1. A piano keyboard UI with CSS styling 2. Mouse click/touch support for playing notes 3. Computer keyboard mapping (e.g., A,S,D,F,G,H,J for white keys, W,E,T,Y,U for black keys) 4. ADSR envelope synthesis using Tone.js 5. Visual feedback when keys are pressed Let me create the complete HTML file.

The file has been created successfully. Let me verify it exists.

The index.html file has been created successfully. Let me summarize what I built.
Created `index.html` - a self-contained piano keyboard web app with: **Features:** - **14 keys** (C4 to C#5) - 10 white keys + 4 black keys - **Mouse/Touch support** - click or tap keys to play - **Keyboard support** - A,S,D,F,G,H,J,K for white keys; W,E,T,Y,U,O for black keys - **ADSR envelope controls** - adjustable Attack, Decay, Sustain, Release sliders - **Visual feedback** - keys glow red when pressed with shadow effect - **Audio synthesis** - Triangle oscillator with reverb via Tone.js PolySynth **How it works:** 1. Click "Click to Start" to initialize Tone.js audio context 2. Play by clicking keys or using keyboard shortcuts 3. Adjust ADSR sliders to shape the sound envelope in real-time
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Piano UI with ADSR sliders renders correctly, but requires 'Click to Start' before audio/keys activate; no key press visuals shown.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
