Simulation Lab Builder

A learning goal → a runnable interactive simulation with guided experiments.

Purpose

Some concepts only click when you can play with them (orbits, gravity, wave interference, scale). This skill produces a self-contained interactive simulation — parameters the learner can tune, plus a short set of guided experiments that lead to the intended insight — runnable from a single HTML file.

When it fires

• Keyword triggers: simulation, interactive lab, sandbox, interactive demo, visualize this
• File triggers: sims/**, *.sim.html
• Command triggers: /simulation-lab-builder

Inputs

Workflow

1. State the insight — the one thing a learner should walk away understanding. ✅ Check: the sim can actually demonstrate it.
2. Model — the minimal correct model (equations/rules) that produces the behavior. Keep physics honest within stated simplifications.
3. Build the sim — single-file HTML/JS (or p5.js sketch) with tunable controls and clear rendering.
4. Guided experiments — 2–4 prompts ("set gravity to 0 — what happens?") that surface the insight.
5. Self-check — the sim runs without errors; controls visibly affect behavior.

Output contract

{
  "goal": "string",
  "model_notes": "string — equations/rules + simplifications",
  "code": "string — single-file HTML/JS or p5.js sketch",
  "experiments": ["string — guided prompts"],
  "stack": "p5js | vanilla"
}

Tools & MCP

• Tools: Write, Bash/browser to smoke-test. MCP: none required.

Quality bar

• Runs from a single file without external build steps.
• Model is physically honest within its stated simplifications.
• Controls measurably change the simulation.
• Experiments lead to the stated insight.

Example

Input: goal "show how orbital speed changes with distance" → a p5.js two-body sim with a distance slider and three guided experiments.
