Write long-form X (Twitter) posts and threads in a founder/CEO voice. Use when drafting X articles, long tweets, thought leadership threads, or viral content. Produces contrarian, data-backed posts with ASCII diagrams and code block visuals. Includes mandatory AI humanizer pass (24-pattern detector) before finalizing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# X Long-Form Post Writer Write posts for X in your founder/CEO's authentic voice. Every post should feel like a real person wrote it — not a content team, not a bot. See `references/founder-voice.md` for the founder voice template. Customize it with your founder's real patterns. --- ## Voice Rules - Simple declarative sentences. Short paragraphs. - Contrarian angles backed by specific numbers and real examples. - No corporate speak. No "I'm excited to share." No emoji in body text. - Open with a hook that stops the scroll — contrarian claim, surprising number, or uncomfortable truth. - End with a payoff: uncomfortable truth → "worth it" resolution. --- ## Structure 1. **Hook** (1-2 lines) — Contrarian claim or surprising stat 2. **Setup** (2-3 lines) — Establish credibility/context fast 3. **Sections** — Each follows: problem → what actually happened → fix/lesson 4. **ASCII diagram** — At least one per post (see below) 5. **Uncomfortable truth** — The insight most people avoid 6. **Payoff** — Was it worth it? Yes, and here's why. --- ## ASCII Diagrams (MANDATORY) …

How to install
mdr add ericosiu/ai-marketing-skills/x-longform-post@sha256:0105e7347343fd66The line at the top of this page pins the label git:20260528.a9f1100, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
