Design data-driven Godot 4.x games with custom Resource classes: define typed data with class_name + @export, save/load .tres/.res files, instance and duplicate resources, and load on demand with ResourceLoader (incl. threaded loading). Use when modeling items/stats/configs as data in a Godot project, creating .tres resources, or working with custom Resource subclasses and ResourceLoader/ResourceSaver.
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 machine, behavior tree, blackboard, A*, navmesh, seek, or patrol/chase.
Set up and debug a Phaser 3 game: the Game config, the Scene lifecycle (init/preload/create/update), the asset loader, cameras, and cross-scene communication. Use when building or debugging a Phaser 3 game — when the user mentions Phaser, Phaser.Game, Phaser.Scene, preload/create/update, this.load, this.add, or scene transitions. For Arcade Physics movement/collisions use phaser-arcade-physics.
Rspress best practices for config, CLI workflow, content organization, frontmatter, MDX, themes, i18n, search, static assets, deployment, and debugging. Use when writing, reviewing, or troubleshooting Rspress documentation sites.
Guide for creating, structuring, and improving Claude skills (SKILL.md). Use when building a new skill, reviewing an existing skill, writing SKILL.md frontmatter, defining trigger conditions, troubleshooting skill problems (not triggering, over-triggering, instructions not followed), or planning skill distribution. When working on any skill in this repository: also load the cc-best-practices skill, and always update both CLAUDE.md and README.md skill tables after any skill change. Do NOT use for general Claude Code configuration or hook setup.
React Router performance and architecture patterns. Use when writing loaders, actions, forms, routes, or working with React Router data fetching. Triggers on tasks involving React Router routes, data loading, form handling, or route organization.
Monorepo architecture patterns with Turborepo, pnpm workspaces, and shared packages. Use when setting up multi-package repositories, shared libraries, or micro-frontend architectures.
Next.js 14+ App Router best practices including Server Components, data fetching, caching, and Vercel optimization patterns. Use for Next.js development with waterfall prevention, bundle optimization, and server actions.
React 19 patterns and breaking changes vs React 18. Trigger: When writing React 19 components/hooks in .tsx (ref as prop, new hooks, Actions, deprecations). If using Next.js App Router/Server Actions, also use nextjs-15.
Provide expert guidance on backend and database services. Advises on database design, APIs, authentication, and deployment.
Enhance and improve image quality and visual content. Applies enhancement techniques, color correction, and optimization transformations.
Reviews and validates agent skills against best practices. Triggers on "review this skill", "check my skill", "validate skill", "is this skill well-written", or when creating/editing skills.
