It orchestrates isolated agents through reconnaissance, coverage-led hunting, candidate validation, structured output, independent record verification, and target-neutral reporting. This is the skill that seeded Cloudflare's vulnerability discovery harness, described in Build your own vulnerability harness.

Across the global fleet, shipowners are installing towering rotor sails, rigid wings and suction-based systems on everything from bulk carriers and tankers to containerships. LNG carriers could be next. The idea is not to turn modern cargo ships back into sailing vessels.
