1# LinkedIn Hook Extractor
2 
3Paste 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.
4 
5## When to use
6 
7- User finds a viral post they want to study
8- User wants to replicate a specific creator's pattern
9- Before `linkedin-post-writer` to seed a draft with a proven structure
10 
11## Input
12 
13A LinkedIn post URL (any type: activity, share, ugcPost).
14 
15## Output
16 
17- **Formula identified** (F1-F20 from `../../references/hook-formulas.md`) with confidence score
18- **Structural breakdown:**
19  - Hook lines (first 210 chars)
20  - Body architecture (sections + what each does)
21  - Close pattern
22  - Reaction-triggering devices (numbers, named entities, vulnerabilities)
23- **Why it worked** psychologically
24- **Blank template** filled with slot markers matched to the original, ready for the user's voice
25- **Cautions:** anything in the original post that would fail 2026 audit (em dashes above the cap, AI vocab, outdated tactics), plus the 2026 reach-note flags from `../../references/hook-formulas.md`: a question as line 1, a "Here's what/how" or "Stop X, start Y" opener, a "The result?" / "Plot twist:" bridge, an unpaid curiosity gap, "comment X to get Y" bait, or announced candor with no dated fact. A viral source post may have used these; the template should not copy them.
