// Quantizes all generated PNG assets (sprites, tiles, background) to a named 8-bit color palette to achieve visual coherence. Run after sprite-artist, tile-artist, and bg-artist, before codesmith. Writes state.style.palette so downstream skills know the chosen palette.
Generates genre-appropriate sound effects and looping background music for a generated game. When ELEVENLABS_API_KEY is set, calls the ElevenLabs text-to-sound-effects API for real MP3 audio; otherwise falls back to Web Audio oscillator synthesis. Produces sfx.json, music.json, and AudioManager.js. Run in parallel with art generation stages.
Writes the gameplay code for a Phaser 3 game (src/scenes/Game.js plus optional helpers). Reads the GDD, levels, and sprite/tile manifest; produces ES module code that consumes assets by name (never magic numbers). Use after sprite-artist and tile-artist have produced a complete manifest.
Orchestrator skill that turns a one-line description into a runnable Phaser 3 game. Coordinates eight sub-skills (game-designer, world-architect, sprite-artist, tile-artist, bg-artist, codesmith, playtester, refiner) into a deterministic-where-possible, LLM-where-necessary pipeline. Image generation uses GPT Image 2 (gpt-image-2) at low quality by default. Use when the user wants to generate, refine, or test a 2D HTML5 game from natural language.
Static analysis of Game.js that cross-references every animation key and texture key against manifest.json. Catches "Animation not found" and "Texture not found" bugs before the browser is opened. Run after codesmith, before playtester.
Checks 5 mobile-compatibility properties in the generated game (roundPixels, image-rendering CSS, devicePixelRatio, touch input, AudioContext unlock) and patches any missing items. Run after codesmith, before playtester.
Replaces the serial playtester → gap-checker chain with 4 concurrent QA workers: static analysis (no browser), golden-path scenario runner, dynamic fuzzer, and physics debug validator. Merges all results into a single failure list for the refiner. Cuts QA time from ~2 min to ~30s.

Applies color palette constraints to all generated PNG assets so every sprite, tile, and background shares the same enumerated color set. Without this, GPT Image 2 returns arbitrary colors and assets from the same game look like they came from different games.
After all art generation (sprite-artist, tile-artist, bg-artist) and before codesmith. Also run if the user says "make the art more cohesive" or "unify the palette."
