Reverse-engineer the hook from a high-share Facebook Page post, from its URL or pasted text. Identifies which of the 10 canonical 2026 Facebook formulas it uses (one-line opinion, tiny number, ask-the-page question, this-or-that, behind-the-scenes, story post, announcement, spotlight), explains why it earned shares or comments, and returns a blank template mapped to your topic. Use to learn from a Page post you admire. Not for writing your own (use fb-post-writer).
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 Hook Extractor Paste a high-share Page post URL (or the text). Get back: which hook formula it uses, the exact structure, why it worked, and a blank template you can fill with your own voice. ## When to use - User finds a high-share Page post they want to study - User wants to replicate a specific Page's pattern - Before `fb-post-writer`, to seed a draft with a proven shape ## Input A Facebook Page post URL (any of the many shapes: `/posts/`, `permalink.php`, `/watch/`, `share/p/`). For a `share/p/` link the page and post ids are hidden behind an opaque token, so paste the post text. The bundle has no built-in Page reader, so the user pastes the post text either way. ## Output - **Formula identified** (FB1-FB10 from `../../references/hook-formulas.md`) with a confidence score - **Container:** short post vs story post, and why that container fit the idea - **Structural breakdown:** - The hook line (and for a story post, how the first line earns the "See more" tap) - Body architecture (the beats, for a longer post) - The close (what earns the share or the comment) - Interaction-triggering devices (numbers, named entities, the question, the turn) …

How to install
mdr add sergebulaev/facebook-skills/fb-hook-extractor@sha256:b2f1e7ac55b978eeThe line at the top of this page pins the label git:20261015.2ae9980, 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.
