The user wants me to create a single-page web app with a playable piano keyboard that: 1. Uses tone.min.js (already present in the directory) 2. Is controlled by mouse and computer keys 3. Synthesizes notes with an ADSR envelope 4. Has visual key feedback 5. Everything in one self-contained index.html file Let me first check what's in the current directory to see if tone.min.js is there, then create the HTML file.

<think>
I've created a complete playable piano keyboard in `/tmp/ws/index.html`. Here's what it includes: **Features:** - **13-note keyboard** (C4 to C5) with both white and black keys - **Mouse control** - click and hold keys to play - **Keyboard support** - use `A S D F G H J` for white keys, `W E T Y U` for black keys - **ADSR envelope** on every note (Attack, Decay, Sustain, Release) - **Visual feedback** - keys glow red when pressed - **4 waveform options** - sine, triangle, square, sawtooth - **Volume control** - adjustable from -30dB to 0dB **Controls panel:** - Attack/Decay/Sustain/Release sliders (real-time adjustment) - Volume slider - Waveform selector dropdown The app requires user interaction to start (browser audio policy). Click "Click to Start" or press any key to activate the audio engine and display the keyboard. The Tone.js synth is configured with an ADSR envelope that can be adjusted while playing.
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 only appears after WASD (activating audio), but triggerAttack errors mean notes likely don't actually sound.

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.
