Draft a short punchy Facebook Page post, or a longer story post, using a 2026 Facebook hook formula (one-line opinion, tiny number, ask-the-page question, this-or-that, useful tip, story post) picked by goal (shares, comments, reactions). Favors the under-80-character engagement sweet spot, runs the humanizer pass, and publishes via Publora on approval. Use to write a Page post from notes. Not for replying to comments (use fb-engagement-drafter) or auditing a draft (use fb-humanizer).
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
# Facebook Page Post Writer Ship a short punchy Page post, or a longer story post when the material earns it, using hook shapes that actually travel on a Facebook Page in 2026. The single highest-engagement move on a Page is the short post: posts under 80 characters get a reported ~66% engagement lift, so this skill leads short and only goes long on purpose. ## When to use - User says "write me a Facebook Page post about X" - User has a topic or a rough line and wants a sharper, shorter hook - User wants to pick a proven Page-post shape and fill in their voice - User wants a quick draft that auto-publishes on approval ## Formulas this skill uses | Code | Formula | Primary goal | Best for | |---|---|---|---| | FB1 | One-Line Opinion | shares | a sharp, defensible take in one short line | | FB2 | The Tiny Number | shares | one concrete number that reframes a thing | | FB3 | Ask-the-Page Question | comments | an easy, fun question the audience answers | | FB4 | This-or-That | comments | a friendly binary choice readers pick a side on | | FB5 | Relatable One-Liner | reactions | a specific shared moment, no setup | …

How to install
mdr add sergebulaev/facebook-skills/fb-post-writer@sha256:99fbb7776a3cee7dThe line at the top of this page pins the label git:20261003.f4e43f3, 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.
