Provides REQ-* key pattern definitions, validation rules, and traceability operations. Use for understanding requirement key formats, validating keys, or tracing requirements through the SDLC lifecycle.

Filters PlatformIO output to reduce token usage in agentic tools. Returns success confirmation on successful builds and only error lines on failures instead of full logs. Use when agentic tools need to run PlatformIO commands to reduce context token consumption.

Global frontend aesthetics skill that helps Claude avoid generic "AI slop" UI and make bold, intentional visual decisions while still honoring each project's design-dna, tokens, and architecture.

Creates unique web designs with brand identity, color palettes, typography, and modern UI/UX patterns. Use for brand identity development, visual design systems, layout composition, and responsive web design. Activate on "web design", "brand identity", "color palette", "UI design", "visual design", "layout". NOT for typography details (use typography-expert), color theory deep-dives (use color-theory-expert), design system tokens (use design-system-creator), or code implementation without design direction.

Use when creating or reviewing articles, implementing SEO, ensuring professional quality, checking readability metrics.

Comprehensive software architecture skill for designing scalable, maintainable systems using ReactJS, NextJS, NodeJS, Express, React Native, Swift, Kotlin, Flutter, Postgres, GraphQL, Go, Python. Includes architecture diagram generation, system design patterns, tech stack decision frameworks, and dependency analysis. Use when designing system architecture, making technical decisions, creating architecture diagrams, evaluating trade-offs, or defining integration patterns.

Defines editorial priorities for AndesRC blog. Maps topics to funnel stages (TOFU/MOFU/BOFU), identifies pillar vs. satellite content, and ensures alignment with the 4 content pillars. Use when starting a new content cycle or prioritizing the backlog.

Design and build reusable, maintainable UI components following modern architecture patterns for React, Vue, or other frameworks. Use this skill when creating component files (.jsx, .tsx, .vue), implementing component logic, managing component state, defining props interfaces, or organizing component hierarchies in directories like components/, views/, or pages/. Apply this skill when building functional components with hooks (React), composition API components (Vue), single-file components, implementing component composition patterns, managing local vs. lifted state, or creating custom hooks for shared logic. This skill ensures components follow single responsibility principle, are properly encapsulated, have clear prop interfaces with TypeScript types, support reusability across contexts, and follow modern patterns like atomic design, container/presentational separation, and compound components.

Instrument LLM API calls with proper spans, tokens, and latency

Core concepts for building LangGraph applications. Use when creating StateGraph workflows, defining nodes and edges, managing state with TypedDict/Pydantic, or understanding basic graph structure. Covers state schemas, reducers, node functions, edge types (normal, conditional), and graph compilation.

Design and implement visual regression testing for UI changes. Definesscreenshot coverage, rendering stabilization, baseline management, and CIintegration (e.g., Playwright screenshots, Percy/Chromatic). Use whenUI/styling/layout changes need protection against regressions, or when addingscreenshot-based tests to a web/WASM/desktop UI.

Guide for building robust API integration layers in React/TypeScript applications. Use when implementing HTTP clients (axios/fetch), request/response interceptors, authentication token handling, error handling strategies, retry logic, request cancellation, or organizing API services. Triggers on questions about API client setup, custom hooks for data fetching, React Query/SWR integration, or service layer patterns.
