USE WHEN any other Marketplace skill needs to actually click Send on an approved outbound message: routes to the thread, replaces any Facebook prefilled opener, types the approved text via native keystrokes, verifies the composer value byte-for-byte, clicks Send, confirms the bubble appears in the conversation, and updates the per-thread state file. DON'T USE WHEN no approved exact-text + approval token is in hand — this skill refuses to send without both.
