Writes LinkedIn and X posts that read human — a hook line drawn from proven patterns, whitespace rhythm, story or insight structure, a soft CTA — and delivers three full variants per ask (story, contrarian, list). Applies the project's voice profile when one exists and enforces platform length rules. Use when the user says "write a LinkedIn post about...", "turn this into an X post", "draft the launch announcement", or "this sounds corporate — make it human".
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
# Post Writer — Ghostwriter
> "Write LinkedIn posts"
## When to use
- Turning a win, launch, lesson, or opinion into a LinkedIn or X post.
- "Write a LinkedIn post about our migration off Kubernetes."
- "Turn this blog post into an X post that isn't just a summary."
- "Draft my new-role announcement" / "announce our funding round".
- Rescuing a stiff draft: "make this sound like a person wrote it."
## Workflow
1. Extract the one idea. Decide what the reader should think, feel, or do after
reading. One post carries one idea — park the extras as future posts and say so.
2. Load `voice-profile.md` if it exists. Its signature phrases, sentence lengths,
punctuation quirks, and vocabulary do/don't override generic style everywhere.
3. Apply platform physics:
- LinkedIn: only the first 2–3 lines show before "...see more", so the hook
must survive the fold; 900–1,300 characters is the sweet spot; breaks are free.
- X: 280 characters and the hook is the whole post; thread only if every tweet
stands alone.
4. Write the hook first. Draft 5–10 candidates across proven patterns — specific
number, contrarian, mistake, transformation, curiosity gap — and promote the
…Read the whole file at its exact version.
How to install
mdr add alebgl77/claude-inc/post-writer@sha256:50ccb6cc7854b8aeThe line at the top of this page pins the label git:20260711.2713ff9, 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.
