Skill UI

Authorized security testing skill for hunting web cache poisoning and password reset host-header injection. Maps CDN caching layers, probes unkeyed headers such as X-Forwarded-Host, and verifies cache HIT signals to confirm exploitable poisoned responses.

Senior Laravel Engineer skill for production-grade, maintainable, and idiomatic Laravel solutions. Covers architecture, validation, Eloquent optimization, API design, authentication, caching, queues, and code review.

Architecture and integration sketches for LLM applications, covering RAG retrieval, tool dispatch, agent loops, caching, privacy boundaries and verification requirements before production use.

Cut LLM costs and latency with three caching layers: exact-match Redis cache, semantic similarity cache (GPTCache/Qdrant), and provider-side prompt caching. Ideal for FAQ bots, support tools and high-volume APIs.

This skill helps reduce LLM API and infrastructure costs by 50-90% using strategies like model selection, prompt caching, batching, quantization, and self-hosting. It covers cost tracking, right-sizing models for tasks, provider-side caching, and semantic caching to avoid redundant calls. Suitable for developers managing AI spend and optimizing cloud infrastructure.

Deploy a unified API gateway for LLM traffic with load balancing, rate limiting, key management, semantic caching, fallback routing, and cost tracking.

Use this skill for implementing or debugging network requests, API calls, and data fetching in React Native and Expo projects. Covers fetch API, React Query, SWR, caching strategies, offline support, and Expo Router data loaders. Essential for handling authentication, environment variables, and network errors effectively.

Master Next.js App Router development with guidelines on Server Components, data fetching strategies, routing patterns, and performance optimization. Learn to structure projects, handle API routes, and implement caching effectively for scalable web applications.

This skill helps configure and optimize Nx monorepo workspaces. It covers setting up new workspaces, defining project boundaries, optimizing build caching, and implementing affected commands for CI. It includes best practices for library types like feature, ui, and data-access, along with configuration templates for nx.json and project.json to manage dependencies effectively.

This skill enables diagnosing performance bottlenecks in applications and infrastructure through profiling, tracing, and load testing. It covers observability setup, latency optimization, caching strategies, and scalability planning. Ideal for optimizing backend, frontend, and distributed systems to ensure high throughput and reliability.

A comprehensive guide and methodology for identifying, measuring, and fixing performance bottlenecks across the entire stack. This skill covers optimizing database queries (e.g., N+1 problems, missing indexes), improving API efficiency (caching, parallel processing), and enhancing frontend performance (memoization, code splitting, image optimization). It emphasizes the critical 'Measure First' principle to ensure all optimizations are data-driven and effective.

Caching strategies for LLM prompts, including Anthropic prompt caching, response caching, cache invalidation, and Cache Augmented Generation (CAG) to reduce latency and cost.
