Skill Claude CodeCodex
Generate visual assets from text prompts: PNG images (Gemini / xAI Grok, or local Qwen-Image when installed), GLB 3D models (Tripo CLI), rigged characters, retargeted animations, and frame-by-frame animated sprites, plus background removal. Use whenever a game needs generated art.
Skill Claude Code
Execute Unity tests (EditMode or PlayMode) and return per-test results. Supports filtering by test assembly, namespace, class, and method. Refreshes the AssetDatabase first; defers execution across domain reloads if scripts changed. Precondition: every open scene must be saved — dirty scenes abort the run.

Drive a running Unity Editor or development Player from the command line via the unity-pipeline package — install the package, keep the editor ticking while unfocused, run the edit→recompile→runtests loop, evaluate C#, and hot-reload files at runtime. Use when an agent needs to control a live Unity instance, automate…
Skill Claude Code
Evaluate the current tag's quality: enforce the playable-closed-loop gate, maintain a single cross-tag e2e/ suite that always reflects the current game (add tests for new mechanics, prune tests for mechanics this tag deliberately removed), and reason about gameplay quality. Independent from the build process — fresh…

Skill Claude CodeCodex
Capture reusable patterns from a finished project and lift them into framework-level priors (contracts, modules, skeletons) that future projects inherit. Run only when the user explicitly requests self-evolution; the orchestrator executes the workflow.

Use when a user provides one baseline image and requests game animation frames, sprite sequences, attack/walk/idle/hit/death/casting motion, transparent PNG frames, a spritesheet, keyframe prompts, or consistent whole-character pose animation.
Skill Claude CodeCodex
Build 2D game sprite sheets by generating motion with MiniMax H3 (Hailuo) video, then cutting the footage into validated chroma-keyed sprite frames - the Mortal Kombat method with a video model instead of filmed actors. Covers the character-still recipe, the idle-pin trick that keeps every move on-model and loopable…
