Generate visual assets from text prompts: PNG images (Gemini / xAI Grok), GLB 3D models (Tripo3D), rigged biped characters, retargeted animations, and frame-by-frame animated sprites, plus background removal. Use whenever a game needs generated art.
Get detailed data about a shader asset — properties, subshaders, passes, compilation messages, and supported status. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' with t:Shader or 'assets-shader-list-all' to locate the shader first.
Get detailed information about a specific Component on a GameObject — type, enabled state, and (optionally) serialized fields and properties. Supports token-saving path-scoped reads via paths or viewQuery. Use 'gameobject-find' to list components first.
Find a specific GameObject in the opened Prefab (preferred when present) or the active Scene. Optionally include editable data, components preview, bounds, and limited hierarchy. Supports token-saving path-scoped reads via paths or viewQuery.
A pipeline for turning HTML interface prototypes into Unity UGUI Prefabs, which are reusable Unity interface objects. It uses browser-rendered layout data to preserve positions, images, text, controls, and device-adaptation intentions.
Verify a Godot AI change before committing — ruff, pytest, GDScript testrun against a live editor, and live-smoke of changed tools. Use before every commit, and whenever asked to check that a change actually works.
Build a production behavior-tree runtime (Blackboard, action/condition leaves, sequence/selector/parallel composites, decorators) and a Utility AI system (response curves — linear, exponential, sigmoid, quadratic — considerations, and action evaluators), plus hybrid BT-drives-Utility agents. Use when implementing a…
Add "juice" and game feel that makes actions satisfying — screen shake, hit-stop/freeze frames, tweened/eased motion, squash & stretch, knockback, and layered audio-visual feedback — as engine-neutral techniques that pair with the detected engine's tween, particle, and camera APIs. Use when the user mentions game…
Find and fix game performance problems methodically — measure with the engine profiler first, reason about the frame-time budget, locate the CPU-vs-GPU bottleneck, then apply the right fix: object pooling, draw-call batching, fewer allocations/GC spikes, and asset budgets. Engine- neutral method that pairs with each…
Use when working with 3D-specific systems — materials, lighting, shadows, environment, global illumination, fog, LOD, occlusion culling, and decals in Godot 4.3+.
Clarifies game design requirements and produces a Game Design Document (GDD). Use this skill BEFORE writing any game code. Triggers when the user describes a game idea, says "make a game", "build a {genre}", "I want a platformer", "create a tower defense", or provides any game concept — even vague ones like "make…
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…
Fix gaps identified by the Evaluator. Generates GAP.md from evaluation.json, dispatches workers to address critical/major issues, then runs one final verify+review pass. Unlike gm-build (PLAN.md-driven), gm-fixgap is GAP.md-driven. Explicit invocation only — use /gm-fixgap.
Design NPC and enemy decision-making with finite state machines, behavior trees, steering behaviors, and A pathfinding — engine-neutral algorithms that pair with the detected engine's navigation API. Use when building enemy AI, an FSM or behavior tree, steering/flocking, or pathfinding, or when the user mentions state…
Find and actually LOOK at real photographs — keyless image-search APIs, downloaded to disk so they render as images. Use before building any place, material, vehicle, sky or lighting condition, and again when judging your own screenshots.
Set up player input in Unreal Engine 5 with Enhanced Input: Input Actions, Input Mapping Contexts, modifiers and triggers, adding the mapping context, and binding actions by ETriggerEvent. Use when wiring movement/look/jump input, creating IA/IMC assets, binding in C++ or Blueprints, or when the user mentions Enhanced…
A structured method for turning a one-sentence game idea into a testable design plan, covering player actions, the core loop, scope, assumptions, and validation.
A game-design document writer that turns research, game ideas, player goals, testing plans, diagrams, and production limits into proposals, design documents, or funding pitches.
A guide for turning game-experience questions into short, measurable experiments. Experience density means how many meaningful choices or events a player encounters over time.
Provider-neutral open-source skill for planning and producing game-runtime art assets and animation: static props/icons, canonical character sheets, combat sprites, 3D/video motion references, Veo/Seedance-style video-to-frames, cinematic ultimates, backgrounds, FX, SFX, runtime packaging, and QA. Use when building…
