AI coding agents are smart generalists but lack the deep procedural knowledge senior engineers carry. TechSkills bridges that gap — an open-source library of loadable SKILL.md files that give any AI agent structured workflows, design checklists, and production-ready patterns. Skills use progressive loading — no context window waste. Agent-agnostic, framework-neutral, eval-driven. Currently: frontend-engineer & backend-engineer skills. Early stage, community-driven. More skills coming.
