WordPress performance code review and optimization analysis. Use when reviewing WordPress PHP code for performance issues, auditing themes/plugins for scalability, optimizing WP_Query, analyzing caching strategies, checking code before launch, or detecting anti-patterns, or when user mentions "performance review", "optimization audit", "slow WordPress", "slow queries", "high-traffic", "scale WordPress", "code review", "timeout", "500 error", "out of memory", or "site won't load". Detects anti-patterns in database queries, hooks, object caching, AJAX, and template loading.
Framework-specific accessibility patterns, common pitfalls, and code fix templates for React, Next.js, Vue, Angular, Svelte, and Tailwind CSS. Use when generating framework-aware accessibility fixes or checking framework-specific anti-patterns.
Analyzes Rails code quality, architecture, and patterns without modifying code. Use when the user wants a code review, quality analysis, architecture audit, or when user mentions review, audit, code quality, anti-patterns, or SOLID principles. WHEN NOT: Actually implementing fixes (use specialist agents), writing new tests (use rspec-agent), or generating new features.
Comprehensive UI design skill covering fundamentals, patterns, and anti-patterns. Layout, typography, color, spacing, accessibility, motion, and component design. Use when building any web interface, reviewing design quality, or creating distinctive UIs.
Run technical UI quality checks across accessibility, performance, theming, responsiveness, and anti-patterns, then return a scored action plan.
Correct usage of context.Context in Go: propagation, cancellation, timeouts, deadlines, values, and common anti-patterns. Use when: "context usage", "context.Context", "context cancellation", "timeout", "context.WithTimeout", "context.WithCancel", "context values", "context propagation". Do NOT use for: concurrency patterns beyond context (use go-concurrency-review), HTTP middleware context (use go-api-design), or error handling (use go-error-handling).
Analyzes and optimizes SQL queries for performance. Use for index design, query rewriting, EXPLAIN/EXPLAIN ANALYZE interpretation, PostgreSQL tuning, N+1 prevention, CTE and window function optimization, join strategies, and common SQL anti-patterns.
Helps engineering managers plan roadmaps, prioritize work, and communicate priorities effectively — produces the 20% tech debt framework (and its 5 traps), a phased release pressure-test, a maintenance cost model, the Always Green delivery method, sprint anti-patterns, hidden costs of custom features, a critical deadline playbook, the Iron Law of Projects with reference-class forecasting, a "no technical projects" framing, and feature factory warning signs. Use when the user says "roadmap," "quarterly planning," "OKRs," "prioritization," "what should we work on," "planning cycle," "backlog grooming," "stakeholder alignment," "capacity planning," "technical debt," "we're always late," or "leadership doesn't understand engineering work."
Analyzes the variety and depth of assertions across .NET test suites. Use when the user asks to evaluate assertion quality, find shallow testing, identify assertion-free tests (no assertions or only trivial ones like Assert.IsNotNull), flag self-referential or tautological assertions (output equals input on identity/round-trip operations), measure assertion coverage diversity, or audit whether tests verify different facets of correctness. Produces metrics and actionable recommendations. Works with MSTest, xUnit, NUnit, TUnit. DO NOT USE FOR: writing new tests (use writing-mstest-tests), other anti-patterns like flakiness or duplication (use test-anti-patterns), or fixing assertions.
Generate comprehensive philosophy and standards documents for any domain (UX design, landing pages, email outbound, API design, etc.). Load when user says "create philosophy doc", "generate standards for [domain]", "build best practices guide", or "create benchmarking document". Conducts deep research, synthesizes findings, and produces structured philosophy documents with principles, frameworks, anti-patterns, checklists, case studies, and metrics.
Evaluates agent skills against Anthropic's best practices. Use when asked to review, evaluate, assess, or audit a skill for quality. Analyzes SKILL.md structure, naming conventions, description quality, content organization, and identifies anti-patterns. Produces actionable improvement recommendations.
Optimize Playwright E2E tests by removing anti-patterns, implementing smart waits, enabling test sharding, and improving reliability.
