Awesome Gamedev Agent Skills
77 portable SKILL.md skills across 12 engines (Godot, Unity, Unreal, Phaser, PixiJS, three.js, Bevy, pygame, LÖVE, Roblox, Defold, Ebitengine), with a router.
Co-op Anything
Point your coding agent at a single-player game and make it co-op: an MCP server, 13 agent skills and a playbook to research, reverse engineer, build, bot-test and ship co-op mods with Steam relay networking.
Multi-view to Web-ready 3D Asset
A GameSkill original: front, side and back reference prompts, any image-to-3D provider or 3D MCP server, then a tested glTF Transform pass that simplifies, fixes orientation, resizes textures, applies Draco and builds LODs inside a triangle, file-size and shape-deviation budget. Tested on a real 277k-triangle TripoSR output.
pixelfx
244 pixel-art effects written as code (fire, explosions, magic, weather, UI, pickups, critters) plus a draft, render, look, refine loop for making new ones; every effect exports a sprite sheet with Aseprite-style JSON for Godot, Unity, Phaser or any engine.
Three.js Game Skills
Nine Agent Skills for Codex and Claude Code that build playable Three.js browser games, with a director skill, a Vite scaffold and Playwright QA.
3AGameFactory (GameFactory-3A)
An Apache-2.0 framework of agent skills and pipelines that turns a game requirement into assets (image, 3D, motion, audio, CG video) and engine-ready code for UE5, Blender, Unity, Godot 4 and three.js.
Novel to Game
Agent skills for source-grounded adaptation of novels into games: cited design docs, target-runtime builds and evidence-based QA.
GodotPrompter
Agentic skills framework for Godot 4.x: domain-specific skills for project setup, architecture and gameplay systems.
Video to Game
Treat a short gameplay video as the design document: study its frames, palette and cuts, build one playable Three.js game around its one mechanic, then prove it with side-by-side frames and a recorded keyboard playtest. GameSkill tested the whole loop with code-made assets; the author's fal asset step is optional and paid.
Unreal Engine Skills (quodsoler)
31 Unreal Engine C++ skills checked against the UE 5.8 headers: gameplay framework, GAS, animation, networking, rendering, AI, UI, tools and more.
Everything Game Dev Code
An MIT scaffold for AI-assisted game development: 42 agents, 66 commands, 100+ skills and 115 rules for Unity, Unreal, Godot and HTML5, with adapters for Claude Code, Codex, Cursor, OpenCode and Kiro. Plan, write a GDD, set up an engine project or build a whole game with /full-game.
Codixel
A pixel-art skill built on one idea: the agent writes code, it is not a painter. It asks for a reference image, then removes the background, pixelates, rigs with bones and animates it in code with a 2,000-line toolkit (core/pixel.js), showing every step on a sheet before making game files.
Game Decompilation Skill For Claude
Seven Claude Code skills for byte-matching decompilation of retro games: rebuild readable C/C++ function by function, diagnose why a function won't match, and run parallel matcher workers. No license is published, so see the repository for use.
Hermes GameForge
A game-development plugin for Hermes Agent with 10 agent skills and 9 tools: SFX, music, NPC voices, pixel sprites, tilesets, low-poly 3D, web/Godot/Unity builds, a playtester that plays the build, and itch.io export. Runs offline by default.
pyxel-skill
The official agent skill for building and verifying Pyxel retro games, by Pyxel's creator kitao. Bundles the pyxel-mcp server so the agent can run, screenshot and check its own game.
FunPlay Skill
14 MIT agent skills for game development with scripts and tests: sprite-sheet slicing, normal maps, audio conversion, game concept briefs, browser game slices, Unity MCP workflow and Cocos/WeChat minigame rules.
Ludra
A 2D game engine built for AI agents: games are JSON, every error comes with a machine-readable fix, and the agent plays and tests its own game headlessly. Ships a Claude Code plugin and skill.
De-AI Game UI (remove the generic AI look from menus and HUDs, checked by a lint)
A GameSkill original that strips the tells of AI-made game UI (purple-blue gradients, glass panels, neon glows, emoji icons, one big radius, everything centred, identical buttons, epic-journey copy) and rebuilds the screen from the game's own world. Ships a 12-rule lint that reads computed styles in headless Chrome for any framework, a before/after pause menu and a mutation test proving every rule can fail.
Godot MCP (bundled server, run and read errors)
A GameSkill skill that ships the godot-mcp server (Coding-Solo, MIT) pre-built as one Node file, so an agent can drive Godot 4 over MCP: run the game and read its printed output and errors, stop it, launch the editor, create scenes, add nodes, put textures on sprites, export a MeshLibrary and read UIDs. Nothing is installed from npm or GitHub; it needs only Node.js 18+ and Godot 4.
Godot, One Mechanic at a Time (reference folder, grey box, tested mechanics)
A GameSkill original for building a Godot 4 game with an agent in an order that holds up: a reference folder with a style-prompt JSON, a grey box, then one mechanic per prompt in its own script with its own headless playtest, re-running every earlier playtest before the next. Ships templates, checkers for the reference folder and project layout, and a tested 2D example (run and jump, then glide across a gap) whose playtests catch a broken mechanic.
Mechanic Picker (choose 2-3 mechanics that need each other, one page, bot playtest)
A GameSkill original for the step before building: pick two or three game mechanics that work together from 24 cards, scored against your input, day budget and wanted feel, write them on one checked page with a playtest question each, and prove the pair makes a game with a quick bot playtest. Worked example: Lantern Ferry, whose first numbers the bots caught as a one-strategy game.
Procedural Low-Poly Buildings (kit, validator, views)
A GameSkill original: build stylised low-poly buildings in code from a small spec, then prove them: plot and height limits, a triangle budget per tier, closed outward meshes, supported parts, level roofs and side-only taper measured from silhouettes, plus front, side, top and 3/4 renders checked against the geometry.
Style Cards (one art style as hard limits, switch looks by switching cards)
A GameSkill original that writes a game's art style down as a card of measurable limits (canvas, colours and palette, alpha, triangles, shading, materials, textures, voxel grid), pastes it into every asset request and checks every asset against it. Ships 12 cards from pixel and one-bit to low-poly, voxel and toon, a no-dependency PNG checker, a Blender GLB checker and a palette locker; switch the whole look by switching the card.
Underhood
Five free Claude skills for modding games you own: recon, reverse engineering (.NET, IL2CPP, native, pak AES keys, unknown formats), building and testing the mod in game, local art via ComfyUI, and release.
