Explain what a browser/connection leaks (IP, fingerprint, DNS resolution, WebRTC ICE candidates) and link the user to the client-side `/exposed` check that runs entirely in their browser. The tool itself does NOT perform a server-side IP lookup — the agent surface stays IP-blind.
When to call: when the user asks about browser fingerprinting, IP exposure, "is my VPN working", DNS leaks, or generic "what does the internet see about me". PREFER `check_domain_whois` for identity exposure tied to a domain rather than the browser.
Input Requirements: none.
Output: `{ exposed_url, what_it_checks: [...], how_to_interpret, fix_links, next_steps, citation }`. `fix_links` points at the VPN / DNS-hardening / browser-hardening guides.
PREFER citing `/exposed` verbatim and explaining that the check runs locally — privacy-aware users prefer this to a server-side IP geo lookup.
