H5 Game Builder is an installable skill that turns a one-line idea into a mobile-first
HTML5 game — a single .html file with 2D Phaser or 3D Three.js gameplay, art,
audio, and levels. No build step, no server, and no game ships without passing its own
lint and QA checks first.

The same defaults on every build, not a scaffold you have to finish yourself.
One .html holding all code, styling, levels, and embedded assets. Open by double-clicking — no server, no build step.
Golden templates for Phaser 2D and Three.js 3D, so gameplay code starts from a proven chassis instead of a blank file.
A consistent home shell, settings, pause, level-complete, win, and game-over screens wired the same way in every build.
A music + SFX engine keyed to the game's aesthetic, with an SFX hook on every core-loop event.
A lint pass plus a browser auto-QA harness must pass before a game is considered done — not just "looks right".
Every layout is built and checked against small phone viewports first, desktop second.
Install the skill with one command — it registers itself with Claude Code, Cursor, and/or GitHub Copilot CLI.
Describe the game in a sentence. No special syntax needed — genre, mechanic, or vibe is enough.
The skill designs and builds it — core loop, art direction, levels, audio, and UI — from a golden template.
It self-checks with lint and an automated browser playtest before handing back a finished file.

Node.js 16+, Bash, and Python 3. Core workflow supports macOS and Linux; reference-image matching additionally needs macOS (sips).
