REA

Use REA when the user wants to understand how an app or feature works, compare app versions, decompile code, or build a similar feature.

For a website already open in a user-owned Chrome-family browser, start with list_browser_targets and inspect_web_page instead of opening a binary. Use analyze_web_bundle, observe_web_session, discover_webmcp_tools, capture comparison, or screenshot tools only for the corresponding investigation. Ask the user to approve the exact page origins and loopback CDP endpoint before the first call. Browser observation is disabled unless the operator configured REA_BROWSER_OBSERVE_ENABLED, REA_BROWSER_CDP_ENDPOINTS_JSON, and REA_BROWSER_ALLOWED_ORIGINS_JSON before starting REA.
