**Looking into file structure** I’m thinking about creating an index.html file and inspecting the relevant files first. It’s important to make sure I have everything organized before I start. I wonder what other files I might need to connect with the HTML. Should I check for any existing templates or styles? Getting this step right will help ensure that the overall project goes smoothly. Let’s take it one step at a time and see what I come up with!

**Testing syntax for interactions** I think I need to test the existence of certain syntax. The `mousePressed` function in p5 should reset the scene with mouse interactions only when pressed in the draw loop. It’s set to full screen, which is good. I’m considering using p5's `random`, but I wonder if I should only rely on local exact values and not any external ones. I should probably inspect with `grep` to verify.

Created `/tmp/ws/index.html` with a self-contained full-screen p5.js flow-field animation featuring: - 5,200 Perlin-noise-driven particles - Fading trails and evolving HSB colors - Mouse-based field disturbance - Click-to-reseed interaction - Responsive canvas resizing - Minimal atmospheric HUD and particle readouts - No external resources beyond the provided local `p5.min.js`
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
Flowing, colorful Perlin-noise particle trails animate continuously and shift hue with time; inputs mainly alter color/palette.
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.
