HTML Design & Prototypes
HTML is the fastest design surface available — instant feedback loop, real layout engine, real typography, real interaction. Use it to sketch designs even when the production target is React Native, Swift, or anything else. The translation from HTML+CSS to the final framework is mechanical; the design exploration is what's hard.
Pre-flight — run BEFORE writing the artifact
This skill produces an interactive artifact. Invoke the html-skills-listen skill from this plugin first (Skill tool: html-skills:html-skills-listen). It sets up a per-session local receiver and arms a Monitor so user submissions arrive as session notifications instead of as copy-paste round-trips. It's idempotent — invoke every time you fire this skill.
Capture the URL it returns. If it returned one, inject it as window.__CLAUDE_SUBMIT_URL__ in the HTML you're about to write. If it reported web/sandbox mode (no URL returned), generate the HTML without __CLAUDE_SUBMIT_URL__ set — submitToClaude will fall back to clipboard mode automatically.
Skipping this step costs the user a copy-paste round-trip on every submit. Invoking the skill is cheap and idempotent.
