Suggested shell aliases based on usage patterns

WHEN: Coverage analysis, finding untested files, test prioritization, coverage gap identificationWHAT: Line/Branch/Function coverage + untested file list + priority by importance + improvement roadmapWHEN NOT: Test generation → test-generator, Test quality → code-reviewer

Clean Architecture and SOLID principles implementation including dependency injection, layer separation, domain-driven design, hexagonal architecture, and code quality patterns

Use when designing database schemas from business requirements, translating vague requirements into concrete SQL definitions, or validating database designs with non-technical stakeholders. Provides a systematic methodology that decouples logical business modeling from physical implementation to reduce cognitive load and ensure business-driven design.

Master SQL query optimization, indexing strategies, and EXPLAIN analysis to dramatically improve database performance and eliminate slow queries. Use when debugging slow queries, designing database schemas, or optimizing application performance.

Pyright fast Python type checker from Microsoft with VS Code integration and strict type checking modes

Use when decomposing complex work. Dispatch fresh subagent per task, review between tasks. Flow: Load plan → Dispatch task → Review output → Apply feedback → Mark complete → Next task. No skipping reviews, no parallel dispatch.

This skill should be used when implementing rich, interactive React components in LangGraph applications, including weather dashboards, image galleries, flashcards, charts, forms, and custom visualizations. Use when building new agents with custom UI, retrofitting existing agents with generative UI, or implementing specific component types like galleries or interactive forms.

Complete browser automation with Playwright. Auto-detects dev servers, writes clean test scripts to /tmp. Test pages, fill forms, take screenshots, check responsive design, validate UX, test login flows, check links, automate any browser task. Use when user wants to test websites, automate browser interactions, validate web functionality, or perform any browser-based testing.

Complete security patterns for GitHub Actions covering action pinning, GITHUB_TOKEN permissions, third-party action risks, secret management, and runner security.

Get today's date for web searches and date-sensitive tasks. Auto-invoke before any WebSearch that includes a year (e.g., "React 2024", "Python 2025"), when searching for current documentation, latest releases, or recent information. Ensures searches use the correct current year instead of outdated dates.

Creates custom React hooks for SideDish. Use when the user asks to create a new hook, extract shared logic into a hook, or refactor component logic into reusable hooks. Includes TypeScript interfaces, memoization patterns, and index.ts export.

Comprehensive SEO optimization for web applications. Use when asked to improve search rankings, add meta tags, create structured data, generate sitemaps, optimize for Core Web Vitals, or analyze SEO issues. Works with Next.js, Astro, React, and static HTML sites.

Use when implementing any feature or bugfix. Write the test first, watch it fail, write minimal code to pass. Red-Green-Refactor cycle.

Build accessible user interfaces following WCAG guidelines with semantic HTML, keyboard navigation, screen reader support, and proper color contrast. Use this skill when creating or modifying UI components, implementing form inputs, adding interactive elements, working with navigation menus, creating modals or dialogs, or handling focus management. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend code that users interact with. This skill ensures semantic HTML elements (nav, main, button, etc.) that convey meaning to assistive technologies, keyboard navigation with visible focus indicators (focus:ring-2 focus:ring-offset-2 in Tailwind), sufficient color contrast ratios (4.5:1 for normal text), descriptive alt text for images and meaningful labels for form inputs, screen reader testing and verification, ARIA attributes for complex components when semantic HTML isn't sufficient, logical heading structure (h1-h6 in proper order), and proper focus management in dyna
