Write a Threads post or a multi-post chain from a raw idea using 18 hook formulas, in the user's own voice, humanized so it does not read as AI, and checked against the 500-character limit. Use whenever the user wants a Threads post, a thread or chain, a hook, "post this on Threads", "turn this into a thread", or asks for hook options for Threads. Text only. Produces three hook options, one full draft, and a copy-ready block that is never published without an explicit yes.
