What It Does
Agent Skills is a collection of 24 structured skill files β plain Markdown with front matter β encoding the workflows senior engineers follow across the full dev lifecycle.

The timing lands in the middle of what developers are calling the "skills boom" β five of the top-20 GitHub trending repos today carry "skills" in the name, a format popularized by the Claude Code plugin ecosystem. What separates agent-skills from the pile is the author's track record: Addy Osmani is Google's Chrome engineering lead, and the skills are grounded directly in Google's engineering culture β Hyrum's Law in API design, the BeyoncΓ© Rule in testing, trunk-based development in git workflow, and code-as-liability thinking in deprecation.
Multi-tool reach matters too. The same Markdown skill files install into Claude Code's plugin marketplace, Cursor rules, Gemini CLI, GitHub Copilot, Codex, Windsurf, OpenCode, and anything that ac
