Your AI-built app looks done until you use it. Reverse Engineer Anything (REA), the tool past 200,000 GitHub stars, shows how software you own handles the job
REA stands for Reverse Engineer Anything. It’s an open-source tool that gives AI coding assistants such as Codex and Claude Code a way to investigate existing software, including programs whose original source code you don’t have. You point your agent at an application or a supported browser session and ask how a particular feature works. REA supplies tools to inspect the code and behavior. Your agent uses those findings to explain the mechanism and help you build something of your own.

Checkpoint/issues5886-6756-2026-10-15a: fix(a2a): bridge authenticated bearer to A2A OBO plugin
Add an opt-in bearer bridge (A2A_OBO_BEARER_BRIDGE_ENABLED, default false) that exposes the authenticated caller token to allowlisted A2A pre-invoke plugins so an OBO plugin can exchange it for a downstream credential before dispatch. Gate: bridge is active only when the flag is on, an authenticated bearer arrived at the route handler, and 'authorization' is in the agent's passthrough_headers whitelist. Security invariants: The original caller bearer is stripped from downstream_headers before the plugin hook fires;
