Create a full-screen flocking simulation of boids using separation, alignment, and cohesion, drawn as oriented triangles that steer smoothly and flee from the mouse cursor.

We need to create a self-contained HTML file with JS and CSS. Implement boids flocking simulation with separation, alignment, cohesion, oriented triangles, flee from mouse cursor. Should be full-screen.

We'll write index.html directly.

Let's first check current directory, then write file.

We'll create a canvas that fills window. Use requestAnimationLoop.

Implement boid class with position, velocity, acceleration. Flocking rules with parameters. Flee from mouse: apply a repulsion force away from cursor when within some radius.

Draw oriented triangle: compute angle of velocity.

We'll not use any external resources.

Let's proceed.

First, maybe check if any existing index.html. Use bash ls.

bash {"command":"ls -la"}
toolResult

total 4 drwxrwxrwx 2 node node 64 Jul 22 16:48 . drwxr-xr-x 1 root root 4096 Jul 22 16:48 ..

Now create index.html. We'll write the content.

Let's craft HTML.

write /index.html (8491 bytes)
toolResult

EROFS: read-only file system, open '/index.html'

assistant

We need to write to current directory /workspace, not root. The path should be ./index.html or just index.html. Let's write to ./index.html.

We attempted to write to /index.html which is read-only. Use write with path "index.html".

Let's do that.


write index.html (8491 bytes)
toolResult

Successfully wrote 8491 bytes to index.html

assistant
thinking
Now we have index.html in current directory. Let's verify it exists and maybe test quickly by opening? Not needed. Ensure it's correct.

We can do a quick check of file size and maybe head.

Let's read first few lines to confirm.


read {"path":"index.html","limit":20}
toolResult

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Boids Flocking Simulation</title> <style> html, body, canvas { margin: 0; padding: 0; width: 100%; height: 100%; overflow: hidden; background: #111; } canvas { display: block; } </style> </head> <body> [263 more lines in file. Use offset=21 to continue.]

Good. The file is created. The task is to build a single-page web app and write it ALL into one self-contained file named index.html in the current directory. We have done that. We can consider the task complete.

We should output final answer indicating completion.


The self-contained `index.html` file has been created in the current directory. It includes a full-screen flocking simulation of boids with separation, alignment, and cohesion, drawn as oriented triangles that steer smoothly and flee from the mouse cursor. No external resources are used. You can open the file in a browser to see the simulation.

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.

EVALUATION

3/5 working

Boids flock into clusters and drift smoothly with triangle shapes, but no visible reaction to mouse/keyboard input.

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.
