This repository is a curated, battle-tested collection of AI coding skills — structured knowledge files that an AI coding assistant (like Claude / Gemini) reads automatically to produce production-quality code on the first attempt.

Each skill is a senior engineer living inside your editor who specializes in one area. Instead of you explaining context from scratch every session, the assistant reads the relevant skill and already knows the correct APIs, proven patterns, common pitfalls, and how to combine multiple tools cleanly.

> The result: You go from "build me an agent" to a fully structured, memory-enabled, cost-optimized, production-ready LangGraph agent — in a single conversation.
