Jochen AI Rules

Create and resume structured manual session handoffs for long-running development work. Use when approaching context limits, before manual reset, before switching models or IDEs, after a milestone, or when automatic compact would lose important implementation state.

Review current conversation, analyze tasks, errors, and user feedback, extract learning opportunities for skill improvement. Use when user says "reflect", "review session", "what did we learn", "session summary", or after completing a complex task.

Comprehensive full-stack development for web, mobile, and game projects. Handles frontend (React/Vue/Angular), backend (Node.js/Python/Go/Java), mobile (Flutter/React Native/Swift/Kotlin), and game development (Unity/Unreal/Godot). Use when user asks to build, create, develop, implement, debug, or fix any web, mobile, or game project. Do NOT use for design-only tasks (use frontend-design or ui-ux-pro-max instead).

Create agent teams for parallel collaboration. Use when user mentions team, parallel, multi-agent, coordinate, collaborate, review team, multiple perspectives, or says "agent-teams".

MCP server development for AI agents. Designs tool schemas, implements Python/TypeScript servers, creates evaluation tests. Use when user asks to build MCP server, create tool integration, or develop Claude plugins. Supports GitHub/Notion/Slack integrations.

API architecture design and documentation for RESTful, GraphQL, and gRPC services. Creates OpenAPI specifications, defines versioning strategies, and establishes authentication/authorization patterns. Use when user asks to design API, create endpoints, document REST/GraphQL, or plan API architecture.

Audit all .claude/*.md files for redundant instructions, verbose phrasing, and content that could move to memory. Use when user wants to optimize their Claude configuration rules.

Build 2D HTML5 games for the web using Phaser with WebGL/Canvas rendering. Use when creating Phaser game scaffolds, scenes, core loops, or deployment guidance for web-based releases.

List all installed skills with line counts and analyze for improvement opportunities. Use when user wants to review, optimize, or clean up their skill collection.

Standardized Test-Driven Development (TDD) cycle (RED-GREEN-REFACTOR-VERIFY). Use when user asks to write tests, do TDD, implement test-first, or ensure code quality with high test coverage and regression prevention.

UI/UX design-system reasoning and UX quality audit skill. Use when user needs style direction, palette/typography selection, UX review, or design optimization before implementation. Do NOT use for backend logic or database design.

CI/CD pipeline design, containerization, and infrastructure management. Handles Docker, Kubernetes, monitoring setup (Prometheus/Grafana), and infrastructure-as-code (Terraform/Pulumi). Use when user asks to deploy, configure CI/CD, set up Docker/K8s, or manage infrastructure.

Product requirements analysis and planning for structured PRD outputs. Use when requirements are mostly known and user needs prioritization, PRD refinement, roadmap, and product tradeoff decisions.

Creates simple Three.js web apps with scene setup, lighting, geometries, materials, animations, and responsive rendering. Use for: "Create a threejs scene/app/showcase" or when user wants 3D web content. Supports ES modules, modern Three.js r150+ APIs.

Project context engine for repo orientation, cached handoff, and task-focused code retrieval.

Rapid prototyping tool for React interactive demos and single-file HTML artifacts. Uses shadcn/ui component library with 40+ components. Use when user asks to create React demo, build HTML artifact, prototype UI, or create product demo. Perfect for design validation and shareable browser previews.

Database architecture design, schema optimization, query performance tuning, and data migration. Handles PostgreSQL, MySQL, MongoDB, Redis. Use when user asks to design database, optimize queries, create migrations, or improve database performance. Do NOT use for frontend or application logic.

Comprehensive code quality assurance covering code review, testing strategies, and security auditing. Identifies bugs, vulnerabilities, performance issues, and maintainability problems. Use when user asks to review code, audit security, write tests, or improve code quality. Follows OWASP and industry best practices.

Performance bottleneck identification and optimization. Handles database query optimization, caching strategies, algorithm improvements, and Core Web Vitals tuning (LCP/FID/CLS). Use when user asks to optimize performance, improve speed, fix slow queries, or tune web vitals.
