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.

The user wants a flocking simulation (boids) with: 1. Separation, alignment, and cohesion behaviors 2. Drawn as oriented triangles 3. Smooth steering 4. Mouse fleeing behavior 5. Full-screen 6. All in one self-contained HTML file Let me create this simulation. I'll need to implement: - Boid class with position, velocity, acceleration - Separation - avoid crowding neighbors - Alignment - steer towards average heading of neighbors - Cohesion - steer towards average position of neighbors - Mouse flee behavior - Smooth steering using acceleration limiting - Render as oriented triangles (using canvas) - Full-screen canvas that resizes with window Let me write this out.

The file is created successfully. Let me summarize what I've built.
Created `/tmp/ws/index.html` - a full-screen boids flocking simulation with: **Boid Behaviors:** - **Separation** - boids steer away from nearby neighbors to avoid crowding - **Alignment** - boids steer towards the average heading of nearby boids - **Cohesion** - boids steer towards the average position of nearby boids - **Mouse Fear** - boids flee from the mouse cursor with a radial fear zone - **Edge Handling** - soft boundary steering plus wraparound at screen edges **Visuals:** - Oriented triangles that rotate to match velocity direction - Gradient coloring with hue variations (cyan/blue tones) - Speed-based intensity - faster boids are brighter - Subtle glow effect on each boid - Faint background grid for atmosphere - Red radial gradient shows mouse influence area **Controls:** - Move your mouse to scare the boids - they'll flee and reform their flock - Full responsive canvas that resizes with the window The simulation runs at 120 boids with smooth steering using acceleration limiting (maxForce), creating organic, lifelike flocking behavior.
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
Boids flock as oriented triangles with smooth flocking behavior; mouse fear glow visible but flocks continue independent of 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.
