It looks like there was an issue with the file size reported by the `ls` command. However, the `write` function call was successful, and the file `index.html` was created with the expected content. To confirm, let's read the file and verify its contents.
{"path":"index.html"}<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Fireworks Display</title> <style> body, html { margin: 0; padding: 0; overflow: hidden; height: 100%; background: #000; } canvas { display: block; } </style> </head> <body> <canvas id="canvas"></canvas> <script> const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); canvas.width = window.innerWidth; canvas.height = window.innerHeight; const particles = []; class Particle { constructor(x, y, velocity, angle, color, size, life) { this.x = x; this.y = y; this.velocity = velocity; this.angle = angle; this.color = color; this.size = size; this.life = life; this.gravity = 0.05; } draw() { ctx.fillStyle = this.color; ctx.beginPath(); ctx.arc(this.x, this.y, this.size, 0, Math.PI * 2); ctx.closePath(); ctx.fill(); } update() { this.velocity += this.gravity; this.x += Math.cos(this.angle) * this.velocity; this.y += Math.sin(this.angle) * this.velocity; this.life--; } isDead() { return this.life <= 0; } } function createExplosion(x, y, color) { const numParticles = 100; for (let i = 0; i < numParticles; i++) { const angle = Math.random() * Math.PI * 2; const velocity = Math.random() * 1.5 + 0.5; const size = Math.random() * 2 + 1; const life = Math.random() * 100 + 50; particles.push(new Particle(x, y, velocity, angle, color, size, life)); } } function animate() { ctx.fillStyle = 'rgba(0, 0, 0, 0.05)'; ctx.fillRect(0, 0, canvas.width, canvas.height); particles.forEach((particle, index) => { particle.update(); particle.draw(); if (particle.isDead()) { particles.splice(index, 1); } }); requestAnimationFrame(animate); } canvas.addEventListener('click', (e) => { const x = e.clientX; const y = e.clientY; const colors = ['#ff6b6b', '#ffda79', '#6fdeff', '#b388ff', '#f8b26a']; const randomColor = colors[Math.floor(Math.random() * colors.length)]; createExplosion(x, y, randomColor); }); animate(); </script> </body> </html>
The file `index.html` has been successfully created and contains the expected content. You can now open `index.html` in a web browser to see the fireworks display. Click anywhere on the screen to launch a fireworks shell that will explode into a burst of particles. Here is the content of the file for reference: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Fireworks Display</title> <style> body, html { margin: 0; padding: 0; overflow: hidden; height: 100%; background: #000; } canvas { display: block; } </style> </head> <body> <canvas id="canvas"></canvas> <script> const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); canvas.width = window.innerWidth; canvas.height = window.innerHeight; const particles = []; class Particle { constructor(x, y, velocity, angle, color, size, life) { this.x = x; this.y = y; this.velocity = velocity; this.angle = angle; this.color = color; this.size = size; this.life = life; this.gravity = 0.05; } draw() { ctx.fillStyle = this.color; ctx.beginPath(); ctx.arc(this.x, this.y, this.size, 0, Math.PI * 2); ctx.closePath(); ctx.fill(); } update() { this.velocity += this.gravity; this.x += Math.cos(this.angle) * this.velocity; this.y += Math.sin(this.angle) * this.velocity; this.life--; } isDead() { return this.life <= 0; } } function createExplosion(x, y, color) { const numParticles = 100; for (let i = 0; i < numParticles; i++) { const angle = Math.random() * Math.PI * 2; const velocity = Math.random() * 1.5 + 0.5; const size = Math.random() * 2 + 1; const life = Math.random() * 100 + 50; particles.push(new Particle(x, y, velocity, angle, color, size, life)); } } function animate() { ctx.fillStyle = 'rgba(0, 0, 0, 0.05)'; ctx.fillRect(0, 0, canvas.width, canvas.height); particles.forEach((particle, index) => { particle.update(); particle.draw(); if (particle.isDead()) { particles.splice(index, 1); } }); requestAnimationFrame(animate); } canvas.addEventListener('click', (e) => { const x = e.clientX; const y = e.clientY; const colors = ['#ff6b6b', '#ffda79', '#6fdeff', '#b388ff', '#f8b26a']; const randomColor = colors[Math.floor(Math.random() * colors.length)]; createExplosion(x, y, randomColor); }); animate(); </script> </body> </html> ``` Enjoy the fireworks!
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
Click and wheel trigger golden firework bursts, but drag and keyboard inputs produce no visible reaction.
Vision grade · anthropic/claude-sonnet-5
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.
