Provides comprehensive technology stack auditing with LIVE RESEARCH capability. Analyzes version currency, code patterns, conventions, anti-patterns, and security advisories for ANY framework (Laravel, React, Vue, Symfony, etc.). Use this skill when the user needs technology stack audit, framework best practices review, or package analysis. Produces detailed consultant-style reports with findings and prioritized recommendations — does NOT write implementation code.
Code review for Paweł Lipowczan portfolio project (React+Vite+Tailwind SPA). Use when user wants to review code changes, pull requests, commits, or modifications in portfolio project. Verifies architecture compliance, SEO standards, accessibility (WCAG 2.1 AA), performance (Core Web Vitals), blog system (markdown frontmatter, OG images), prerendering setup, and edge cases. References docs/{PRD.md,SRS.md,TODO.md,blog/BLOG_WORKFLOW.md}. Focuses on bugs, edge cases, and conditions causing errors after deployment.
Vercel React Best Practices for performance and engineering.
Review UI code for Web Interface Guidelines compliance using Vercel Engineering standards.
Diagnose errors and failing tests in Laravel + React + Python applications. Use when encountering bugs, exceptions, stack traces, 500 errors, TypeErrors, failing tests, or unexpected behavior. EXCLUSIVE to debugger agent.
Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".
Use this skill when performing QA reviews of the EVOLEA website (Astro frontend at localhost:4321), Admin Dashboard V2 (localhost:5175), or production sites (planted.com, admin.planted.com). Orchestrates visual inspection, console/network error detection, accessibility auditing, Core Web Vitals measurement, and interactive testing using Chrome DevTools MCP. (project)
Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".
Measure, compare, and improve eo-processor performance safely. Use when adding/changing Rust compute kernels, refactoring hot paths, or making performance claims. Provides a repeatable benchmark protocol with correctness checks, profiling hints, and reporting guidelines.
Performance optimizer with profiling strategies and optimization techniques
Optimize CUDA kernels and GPU code for performance. Use when reviewing CUDA code, analyzing performance, or suggesting GPU optimizations.
Identify and execute independent operations in parallel for 3-5x speedup. Auto-analyzes task dependencies, groups into batches, launches parallel Task() calls. Applies to /optimize (5 checks), /ship pre-flight (5 checks), /implement (task batching), /prototype (N screens). Auto-triggers when detecting multiple independent operations in a phase.
Reviews memory optimization patches using a 5-persona peer review system. Requires unanimous approval backed by benchmarks. Bugs discovered during review are valuable - invoke /validate-correctness to validate them.
Next.js development tooling via MCP. Inspect routes, components, build info, and debug Next.js apps. Use when working on Next.js applications, debugging routing, or inspecting app structure. NOT for general React or non-Next.js projects.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Validate UI changes in the AntonioHC Next.js portfolio using the Chrome DevTools MCP. Use when asked to verify sections, layouts, light/dark theming, responsive behavior, or visual regressions on http://localhost:3000/.
