    About this skill

    One-Click Unsubscribe Header Checker turns owner-supplied local evidence into a deterministic preflight. Bulk marketing messages can carry a body unsubscribe link yet still lack the paired headers required for standards-based one-click behavior. It writes exact findings, a review manifest, a machine-readable gate, and a handoff report. It never performs the external action and never turns a passing check into a certainty.
