Anthropic’s NEW Claude Code Review Agent (Full Open Source Workflow)

I'm on a mission to document my journey of becoming an AI-native founder, sharing every powerful workflow and hard-won insight along the way. You're welcome to join my newsletter (https://patrickellis.beehiiv.com/subs...) or subscribe here, if you're a founder or software engineer looking to build faster and smarter with AI Agents like Claude Code, Codex, Cursor, Gemini, ChatGPT, n8n, image/video gen, and other AI workflows. The speech-to-text voice tool I use is called superwhisper. If you check it out via my affiliate link, it helps support the channel (I may earn a small commission): https://superwhisper.com/?via=patrick Anthropic's Claude Code team just open-sourced the tooling they use to replace manual code reviews with AI agents. If you're drowning in AI-generated code, this agentic review system is the key to unlocking massive velocity while ensuring your code is secure and follows best practices. This video is a step-by-step guide to implementing Anthropic's playbook. I break down their agentic review system, showing you how to use Slash Commands, custom Subagents, and fully automated GitHub Action runners to handle code and security audits. I'll also cover the high-level mental frameworks you need to build powerful, custom AI workflows for your own team.
