Build single-file HTML tools following Simon Willison's patterns - self-contained HTML+JS+CSS applications optimized for LLM generation, no build step, CDN dependencies. Use when creating browser-based tools, utilities, or demos that should be (1) Self-contained in one HTML file, (2) Easy to distribute and host statically, (3) Quick to prototype with LLMs, (4) Client-side only with no server requirements. Ideal for data visualization, API explorers, format converters, debugging tools, and interactive demos.
