Explore AI Agent Skills & Claude Prompts

Recover the true low-resolution pixel grid from upscaled or AI-generated fake pixel art PNGs. Use for snap-to-grid cleanup, native-resolution sprite assets, palette-quantized game art, and known-layout spritesheets. Bundles uv Python scripts ported from Hugo Duprez's spritefusion-pixel-snapper.

pixel-art

Generate 2D pixel art game assets, characters, sprite sheets, background removal, and game backgrounds. Trigger for "pixel art character", "sprite sheet", "walk cycle", "game sprites", "isometric sprites", "side-scroller assets", "RPG character sprites", "idle animation", "attack animation", "jump animation", "game background", "parallax background", "isometric map", "2D game art", "pixel art animation", "top-down character", "explosion sprite sheet", "animated FX from video", "fire/magic effect". Covers character generation (nano-banana-pro / gpt-image-2), sprite sheet animation (nano/edit or fal-ai/gpt-image-2/edit), top-down 4-directional walkers, background removal (Bria), background generation (parallax layers or isometric map), and animated VFX derived from a generated video rendered with additive blend.

game-playbook

The end-to-end recipe for building a GREAT browser game from a one-line idea, plus the craft checklist that separates a tech demo from something fun. Use when the user says 'make a game', 'build a <genre> game' ('make a pixel art top-down slasher', 'build a platformer', 'make a shooter'), 'create a game', or asks to make a game better: 'it feels flat/static/boring', 'add polish/craft', 'screen shake', 'hit stop', 'make it feel good', 'why does my game feel cheap'.

game-feel

Deep game-feel and juice reference — input forgiveness windows, movement curves, hit stop, trauma-based screen shake, squash & stretch, camera kick, audio feel — with concrete numbers from the canonical sources (Swink, Vlambeer, Celeste, Smash). Use when tuning how a game FEELS: 'the controls feel floaty/sluggish/slippery', 'jumping feels bad', 'hits don't land', 'make combat feel weighty', 'add juice', 'coyote time', 'input buffering', 'screen shake feels wrong', or any movement/impact tuning pass. The game-playbook craft checklist covers the basics; this is the deep module with the tuning values.

vfx

Real-time 2D VFX cookbook — layered explosions, hit sparks, muzzle flashes, trails, smoke, pickups, heals, shockwaves, weather — with particle parameter recipes, color/readability rules, and mobile-browser performance budgets, from Diablo's VFX talk, Riot's style guide, saint11, and the GDC VFX bootcamps. Use when: 'add effects', 'make the explosion better', 'hits need more impact' (visual side), 'add a trail/aura/sparkle', 'the effects look muddy/noisy', 'particles tank the framerate', or any Phaser particle emitter / blend mode / post-FX work.

level-design

Level, wave, and arena design patterns from the canon (Nintendo's kishōtenketsu, Scott Rogers' Disneyland weenies, Celeste's room design, Valve's experiential density) — structure, pacing, teaching through geometry, guiding the eye, wave grammar for endless games. Use when designing or generating levels, waves, arenas, or difficulty progression: 'design levels for my platformer', 'the level feels empty/confusing', 'players don't know where to go', 'make better waves', 'how should difficulty ramp', 'add more levels'.

onboarding

First-30-seconds design, invisible tutorials, difficulty curves, failure/retry loops and assist modes for link-shared browser games — distilled from George Fan's PvZ tutorial rules, Jenova Chen's flow thesis, Koster's Theory of Fun, Juul's Art of Failure, and Celeste's Assist Mode. Use when: 'players don't get it', 'people quit immediately', 'does it need a tutorial?', 'too hard/too easy', 'tune the difficulty', 'make the start better', 'add an easy mode', or auditing a game's first minute before shipping.
