GitHub·high signal

Google Director Addy Osmani released Agent Skills, an open-source framework encoding 19 senior-engineer workflows into AI coding agent skills with 7 slash commands (/spec, /plan, /build, /test, /review, /code-simplify, /ship) covering the full development lifecycle. The framework directly addresses AI agents that 'skip specs, tests, and security reviews, optimizing for done over correct' by encoding quality gates from Google engineering practices. Works with Claude Code, Cursor, Antigravity, and any agent accepting Markdown; the announcement went viral with 2,500+ likes and 340+ retweets.
