🔥 Hot Repo: 32K Stars — Stops AI Agents From Cutting Corners

One-liner — A library of 20 structured Markdown skill files that plug into Claude Code, Cursor, Gemini CLI, and four other AI coding agents to enforce the spec-first, test-driven, security-reviewed workflows that senior engineers actually use. - Repo: addyosmani/agent-skillshttps://github.com/addyosmani/agent-skills - Stars: ⭐ 32,250 +3,058 today - Language: Shell - License: MIT --- What It Does Agent Skills is a collection of 20 workflow files written in plain Markdown. Each file — like spec-driven-development, test-driven-development, or security-and-hardening — gives an AI coding agent a structured checklist with steps and verification gates instead of letting it improvise. Seven slash commands /spec, /plan, /build, /test, /review, /code-simplify, /ship map to the full development lifecycle and trigger the relevant skills automatically based on context. Why It's Blowing Up The v0.6.0 release April 28, 2026 shipped a major architectural change: the /ship command now fans out to three specialist agent personas — code-reviewer, security-auditor, and test-engineer — running them in parallel before synthesizing a single go/no-go decision. That turns a single slash command into a lightweight multi-agent review pipeline, which is exactly what teams shipping AI-assisted code into production have been asking for. The author, Addy Osmani, is an engineering manager on Google's Chrome team with a long track record of production-quality open source work. His credibility attracts developers who want battle-tested workflows rather than demo-quality prompts. v0.6.0 also added native support for Gemini CLI, Kiro IDE, and OpenCode, bringing the total compatible agents to seven. The deeper driver is simple: AI coding agents default to the shortest path. They skip writing specs, skip tests, ship without security reviews. Agent Skills encodes the discipline that senior engineers impose on themselves — and junior engineers typically skip — into files an agent can read and f
