Production-grade software engineering skill library for AI agents
Give your AI coding agent fifty real engineering skills.
Default AI agents lack architectural discipline.
Prompting Claude or Cursor without guardrails leads to unoptimized loops, missing error handlers, and untested edge cases across your repository.
raw prompting · sloppy architecture & missing tests
Curated by Google Chrome engineering lead Addy Osmani.
The project contains battle-tested patterns for performance optimization, clean architecture, accessibility audits, and automated migration scripts.
50+ modular skills · architecture, perf & security
Compatible with Claude Code, Cursor, and Codex.
Every skill is written as a markdown tool prompt that drops straight into your agent configuration file with zero setup or build steps.
