clean-validate skillA

clean-validate is agent-read markdown (skill) from cold-iq/coldiq-s-gtm-skills: Verify and validate emails and phone numbers, manage bounce rates, and maintain list hygiene schedules.

Do NOT use for deduplication (use deduplicate) or finding new contacts (use find-contacts)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
