WPILib and FRC robot programming best practices, design patterns, and code guidance for Java. Use when writing, reviewing, or explaining WPILib robot code—command-based project structure, subsystems, autonomous routines, RobotContainer layout, command definition patterns (inline, factory, subclass), or Constants organization.
Astro web framework patterns for content-driven sites. Covers content collections with Zod schemas and loaders, island architecture with selective hydration directives, view transitions with ClientRouter, server-side and hybrid rendering modes, server islands, Astro DB with astro:db, middleware with onRequest, and framework integrations (React, Svelte, Vue). Use when building content-driven websites, configuring island hydration strategies, setting up view transitions, choosing between static and server rendering, integrating UI framework components, defining content collection schemas, or adding middleware.
TanStack Table v8 headless data tables for React. Covers column definitions, sorting, filtering (fuzzy/faceted), server-side pagination with TanStack Query, infinite scroll, virtualization (TanStack Virtual), column/row pinning, row expanding/grouping, column resizing, and reusable Shadcn-styled components. Prevents 15 documented errors including infinite re-renders, React Compiler incompatibility, and server-side state mismatches. Use when building data tables, fixing table performance, implementing server-side pagination, adding filtering/sorting, or debugging table state issues.
Analyze repository structure and generate or update standardized AGENTS.md files that serve as contributor guides for AI agents. Supports both single-repo and monorepo structures. Measures LOC to determine character limits and produces structured documents covering overview, folder structure, patterns, conventions, and working agreements. Update mode refreshes only the standard sections while preserving user-defined custom sections. Use when setting up a new repository, onboarding AI agents to an existing codebase, updating an existing AGENTS.md, or when the user mentions AGENTS.md.
Generate the final MARP deck markdown from definition, deck plan, and visual design artifacts, applying deck-template layout rules deterministically. Use only when all three source artifacts exist.
Activate autonomous Ralph Wiggum loop mode for iterative task completion. Use when you have a well-defined task with clear completion criteria that benefits from persistent, autonomous execution.
Set up Tailwind v4 with shadcn/ui using @theme inline pattern and CSS variable architecture. Four-step mandatory pattern: define CSS variables at root, map to Tailwind utilities, apply base styles, get automatic dark mode. Use when: initializing React projects with Tailwind v4, setting up shadcn/ui dark mode, or fixing colors not working, theme not applying, CSS variables broken, tw-animate-css errors, or migrating from v3.
Reviews error handling strategy and exception design. Use when the user asks to review error handling, when a module throws too many exceptions, or when callers must handle errors they shouldn't need to know about. Applies the "define errors out of existence" principle with a decision tree for exception strategies.
[Testing] Use when creating or enhancing unit tests, integration tests, or defining test strategies for backend and frontend code.
Use when users want to define, codify, or update their brand identity and connect it to design systems. Produces a self-contained user-level skill at ~/.claude/skills/{brand-slug}/SKILL.md that enforces brand guidelines whenever visual assets or written content are created.
Analyze gaps between requirements/features that should be tested and actual test coverage, identifying testing deficiencies and prioritizing test improvements
Arktype patterns for discriminated unions using .merge() and .or(), spread key syntax, and type composition. Use when building union types, combining base schemas with variants, or defining command/event schemas with arktype.
