The full story
REA made one thing obvious to this developer: anything a website ships to the browser, an AI agent can now read and explain. So they built the reverse view for their own products. Diarea (MIT-licensed) scans a site you own, or its build folder, and reports what an agent like REA could learn from it: source maps, secrets left in JavaScript bundles, client-side logic, maps of your APIs and even AI system prompts.
It scores the result and suggests fixes, borrowing REA's "Seen / Inferred / Unknown" labels. The aim is to push as much as possible into "Unknown" by keeping it on the server. It only looks at sites you control and isn't designed to block REA.
