Reverse-engineer the hook formula from a viral LinkedIn post URL. Returns which of the 20 canonical 2026 formulas it uses (anaphora, R.I.P., year-pivot, time-anchor, curiosity-gap, contrarian, comment-gate, emotional cold-open, named-gratitude, and 11 more), why it worked, and a blank template. Use to learn from a competitor's post, not to write your own (use linkedin-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

# LinkedIn Hook Extractor

Paste a viral LinkedIn post URL. Get back: which hook formula it uses, the exact structure, why it worked, and a blank template mapped to your topic.

## When to use

- User finds a viral post they want to study
- User wants to replicate a specific creator's pattern
- Before `linkedin-post-writer` to seed a draft with a proven structure

## Input

A LinkedIn post URL (any type: activity, share, ugcPost).

## Output

- **Formula identified** (F1-F20 from `../../references/hook-formulas.md`) with confidence score
- **Structural breakdown:**
  - Hook lines (first 210 chars)
  - Body architecture (sections + what each does)
  - Close pattern
  - Reaction-triggering devices (numbers, named entities, vulnerabilities)
- **Why it worked** psychologically
- **Blank template** filled with slot markers matched to the original, ready for the user's voice

How to install

The exact contents, by fingerprint
mdr add sergebulaev/linkedin-skills/linkedin-hook-extractor@sha256:32bcf6fab0db0a96

The line at the top of this page pins the label git:20261015.aaa47ea, 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.
