04 gamemaker/build-unity-scene build-unity-scene
Read a Unity project's architecture and level requirements, then create or modify a Unity scene that respects the documented code boundaries, content structure, asset licenses, and validation workflow. Use when a programming agent needs to lay out a level, wire scene objects and components, create reusable prefabs, bind existing gameplay scripts, add camera and lighting, configure build scenes, or turn a documented prototype into a technically valid Unity scene. This skill builds and validates scenes but leaves exploratory gameplay evaluation to play-unity-game.
05 gamemaker/configure-unity-mcp configure-unity-mcp
Install, configure, repair, migrate, and fully validate Codex-to-Unity Editor MCP integration on macOS, Windows, or Linux. Use when setting up Unity MCP on a new project or machine; enabling Codex to read Hierarchy and Inspector state, edit scenes and components, control Play Mode, inspect Console logs, or capture Game View; diagnosing missing Unity tools, failed MCP handshakes, package compilation errors, stale Bee/Library caches, port conflicts, multi-instance routing, or Codex configuration scope; or proving that an existing Unity MCP connection works end to end.
06 gamemaker/discuss-game-design discuss-game-design
Read a game's design documents and discuss a concrete game-design decision while preserving source hierarchy and separating confirmed facts, synthesis, proposals, and open questions. Use when a design agent needs to understand the current vision, analyze a mechanic or loop, compare design options, resolve a design tension, define a prototype, write acceptance criteria, or prepare a clear handoff to art and programming. Discussion is read-only unless the user explicitly asks to update design documents.
07 gamemaker/play-unity-game play-unity-game
Play and evaluate a Unity game or scene after implementation, using the Unity Editor and the closest available player-like input path. Use when Codex needs to actually play a Unity build or Editor scene, verify a gameplay loop, reproduce a gameplay bug, inspect feel and feedback, capture milestone evidence, check reset/replay and soft-lock behavior, or provide a read-only playtest report for design, art, or programming work. Do not use this skill to implement fixes or build scenes unless the user separately asks for changes.
08 gamemaker/search-game-art search-game-art
Search the web for game art assets and produce a source- and license-verified shortlist without downloading or importing files. Use when an art agent needs candidate 2D or 3D models, textures, materials, icons, UI packs, animations, VFX, fonts, or environment kits for a game; when a placeholder needs an open or commercially usable replacement; or when the team needs options compared by visual fit, technical fit, license, attribution, format, and scope. This initial skill is search-only.
