Design

Integration patterns for combining Agent-to-Agent (A2A) Protocol with Model Context Protocol (MCP) for hybrid agent communication. Use when building systems that need both agent-to-agent communication and agent-to-tool integration, implementing composite architectures, or when user mentions A2A+MCP integration, hybrid protocols, or multi-agent tool access.

Use when testing Android apps on ADB-connected devices/emulators - UI automation, screenshots, location spoofing, navigation, app management. Triggers on ADB, emulator, Android testing, location mock, UI test, screenshot walkthrough.

Master RESTful API design principles, HTTP methods, status codes, request/response patterns, versioning, and API best practices for production applications.

Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.

Use when performing mathematical physics computations - Lie algebras, quantum chemistry, neural operators, theorem proving, or scientific validation. Provides guidance on Theory2 CLI usage, computational workflows, and verification methodology.

Expert MCP (Model Context Protocol) orchestration with n8n workflow automation. Master bidirectional MCP integration, expose n8n workflows as AI agent tools, consume MCP servers in workflows, build agentic systems, orchestrate multi-agent workflows, and create production-ready AI-powered automation pipelines with Claude Code integration.

Test data generation patterns using Bogus, test builders, and ABP seeders. Use when: (1) creating realistic test data, (2) implementing test data seeders, (3) building test fixtures, (4) generating fake data for development.

Launch the Karkinos TUI to monitor worker progress in a new terminal window.

Extract clean article text from web pages. Use when user wants to read article content without ads/clutter, save articles, or process web content.

Implement client-side data storage with localStorage, IndexedDB, or SQLite WASM. Use when storing user preferences, caching data, or building offline-first applications.

Configuring Claude Code Hooks System. Design, implement, and manage PreToolUse/PostToolUse/SessionStart/Notification/Stop hooks. Use when enforcing safety checks, auto-formatting, running linters, or triggering automated workflows based on development events.

Analyzes research queries to determine if new strategies are needed, optimizes existing strategies using Langfuse traces, and generates strategy templates

Use when planning animation workflows, deciding between spontaneous vs controlled approaches, or balancing creative freedom with structural precision.

UX research and design toolkit for Senior UX Designer/Researcher including data-driven persona generation, journey mapping, usability testing frameworks, and research synthesis. Use for user research, persona creation, journey mapping, and design validation.

Use when creating or developing, before writing code or implementation plans - refines rough ideas into fully-formed designs through collaborative questioning, alternative exploration, and incremental validation. Don't use during clear 'mechanical' processes

Agent-to-Agent (A2A) server configuration patterns for HTTP, STDIO, SSE, and WebSocket transports. Use when building A2A servers, configuring MCP transports, setting up server endpoints, or when user mentions A2A configuration, server transport, MCP server setup, or agent communication protocols.
