I Used REA + Claude Code on 5 Real Tests. Here's What I Found

About this case

The video demonstrates REA, an open-source MCP tool that collects reverse-engineering evidence for AI agents, used with Claude Code. It covers installation (npx rea-agents setup, Node 22+), then five use cases: how Obsidian's Quick Switcher ranks notes (rebuilt with 0 mismatches over ~19,800 searches), how the scroll video effect on the author's own chocolate site is built, what the Grok Bot Mac app can request, what a news homepage sends on first load (~1,520 requests to 163 domains), and Claude mapping Obsidian and building a small clone in under 8 minutes. The author notes results are location-dependent, that static checks show capability rather than past behaviour, and advises lawful use and not copying others' code.
