Educational code development skill that teaches programming concepts while building applications. Use when the user wants to learn how code works, understand programming concepts, or build an app with detailed explanations. Provides line-by-line breakdowns, explains the 'why' behind code patterns, uses pedagogical teaching methods, and builds apps incrementally with educational commentary at each step.

Testing patterns for React with Jest and React Testing Library. Use when writing tests, mocking modules, testing Zustand stores, or debugging test failures in React web applications.

Comprehensive performance specialist covering analysis, optimization, load testing, and framework-specific performance. Use when identifying bottlenecks, optimizing code, conducting load tests, analyzing Core Web Vitals, fixing memory leaks, or improving application performance across all layers (application, database, frontend). Includes React-specific optimization patterns.

Pattern for verifying your output matches required schema before completing. Use before writing final output to ensure validity.

Posts a progress checkpoint to the currently active GitHub Issue thread. Saves work state including completed tasks, in-progress items, files changed, commits, and blockers without changing workflow phases. Requires an already-claimed in-progress thread. Use when user wants to save progress, record milestones, document blockers, or preserve state before ending a session.

Analyze codebase with tokei (fast line counts by language) and difft (semantic AST-aware diffs). Get quick project overview without manual counting. Triggers on: how big is codebase, count lines of code, what languages, show semantic diff, compare files, code statistics.

Write and run tests for React Native apps using Jest and React Native Testing Library. Use when creating tests, debugging failures, or setting up test infrastructure.

Repository structure and dependency analysis for understanding a codebase's architecture. Use when needing to (1) generate a file tree or structure map, (2) analyze import/dependency graphs, (3) identify entry points and module boundaries, (4) understand the overall layout of an unfamiliar codebase, or (5) prepare for deeper architectural analysis.
