What problem does it solve? Solo developers often struggle to announce a shipped product on X/Twitter without sounding like marketers or writing vague hype. This Skill turns a real launch (with a live link) into a clear single tweet or a 3-4 tweet thread that follows proven structural rules. ## Core Features & Use Cases - Two output variants: Produces both a single tweet (≤ 280 characters) and a 3-4 tweet thread, with the link placed at the end to avoid algorithm penalties. - Hard writing rules: Enforces no leading emojis, no "excited to announce" throat-clearing, front-loaded first 80 characters, show-don't-promise proof points, and explicit pricing. - Optional X evidence packets: Accepts manually pasted or reviewed public post exports (source URL, text, handle, metrics, capture time) to sharpen proof points and phrasing, while requiring explicit human approval before posting. - Use Case: A solo dev shipping a free MIT-licensed GitHub project asks for a launch post and receives a ready-to-review single tweet plus a thread announcing what it is, who it is for, and where to get it. ## Quick Start Ask the assistant to draft a launch tweet and short thread for your shipped product, providing the live link, target audience, pricing, and one concrete proof point.
