I never show the user the actual outline, I only show the response. The user wants me to create a single-page web app in index.html using p5.js (already present as p5.min.js in the current directory). It should be a full-screen flow-field particle animation with: - Thousands of particles advected by Perlin-noise vectors - Fading trails - Colors shifting over time - No external resources, no CDN - CSS in <style>, JS in <script>, all inline in index.html - Use <script src="p5.min.js"></script> to load p5 I should build this and write it to /tmp/ws/index.html. Let me first check if p5.min.js exists there.

I never include anything after the closing tag except the function calls. Let me build a full-screen flow-field particle animation with p5.js. I need to: 1. Use the pre-existing p5.min.js via <script src="p5.min.js"></script> 2. Create a single self-contained index.html 3. Full-screen canvas 4. Thousands of particles advected by Perlin-noise vectors 5. Fading trails 6. Colors shifting over time Let me write the complete file.
/tmp/ws/index.html (4421 bytes)Successfully wrote 4421 bytes to /tmp/ws/index.html
The file is created. Let me verify it's well-formed and check the file size.

I am a strong proponent of incremental, iterative improvement so I may not write the whole response at once. I see the user wants a single-page web app with p5.js, and p5.min.js is already in the working directory. The task was to build a full-screen flow-field particle animation. Index.html is written. Let me verify the file is correct and complete.
The file `/tmp/ws/index.html` has been created (169 lines, 4.4 KB). It's a self-contained single-page web app that: - Loads `p5.min.js` from the current directory via `<script src="p5.min.js"></script>` - Uses **global p5 mode** with `setup()`, `draw()`, and `windowResized()` - Creates a **full-screen** canvas that resizes with the window - Spawns **3000 particles** - Each particle follows a **flow field** generated from **3D Perlin noise** (x, y, and a time-evolving z-offset) - Particles leave **fading trails** drawn as line segments with decreasing alpha (older = more faded) - **Colors shift over time** — the base hue drifts continuously (`baseHue += HUE_SPEED`), and each particle has a slight hue offset for variety - Particles **wrap around** screen edges - On window resize, the canvas, flow-field grid, and particle positions all adjust properly

RUN
EVALUATION
Flow-field particle trails animate continuously with color shifts; pointer input doesn't seem to alter the field, keyboard input untested visually distinct.

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.
