Refactor React Native and TypeScript code to improve maintainability, readability, and performance for cross-platform mobile applications. This skill transforms complex mobile code into clean, well-structured solutions following React Native New Architecture patterns including Fabric, TurboModules, and JSI. It addresses FlatList performance issues, prop drilling, platform-specific code organization, and inline styles. Leverages Expo SDK 52+ features, React Navigation v7, and Reanimated for smooth 60fps animations.
Refactor Scikit-learn and machine learning code to improve maintainability, reproducibility, and adherence to best practices. This skill transforms working ML code into production-ready pipelines that prevent data leakage and ensure reproducible results. It addresses preprocessing outside pipelines, missing random_state parameters, improper cross-validation, and custom transformers not following sklearn API conventions. Implements proper Pipeline and ColumnTransformer patterns, systematic hyperparameter tuning, and appropriate evaluation metrics.

Build terminal user interfaces (TUIs) in Rust with Ratatui (v0.30). Use this skill whenever working with the ratatui crate for creating interactive terminal applications, including: (1) Setting up a new Ratatui project, (2) Creating or modifying terminal UI layouts, (3) Implementing widgets (lists, tables, charts, text, gauges, etc.), (4) Handling keyboard/mouse input and events, (5) Structuring TUI application architecture (TEA, component-based, or monolithic patterns), (6) Writing custom widgets, (7) Managing application state in a TUI context, (8) Terminal setup/teardown and panic handling, (9) Testing TUI rendering with TestBackend. Also triggers for questions about crossterm event handling in a Ratatui context, tui-input, tui-textarea, or any ratatui-* ecosystem crate.
Compile an agent-optimized changelog by cross-referencing git history with plans and documentation. Use when asked to "update changelog", "compile history", "document project evolution", or proactively after major milestones, architectural changes, or when stale/deprecated information is detected that could confuse coding agents.
End-to-end testing patterns with Playwright for full-stack Python/React applications. Use when writing E2E tests for complete user workflows (login, CRUD, navigation), critical path regression tests, or cross-browser validation. Covers test structure, page object model, selector strategy (data-testid > role > label), wait strategies, auth state reuse, test data management, and CI integration. Does NOT cover unit tests or component tests (use pytest-patterns or react-testing-patterns).
Guides developers through configuring HTTP headers security in Tauri v2 applications, covering security headers, custom headers, and CORS configuration for secure cross-origin resource handling.
CSS architecture and styling expert with deep knowledge of modern CSS features, responsive design, CSS-in-JS optimization, performance, accessibility, and design systems.
