Linkedin-skills linkedin-hook-extractor

Reverse-engineer the hook formula from any viral LinkedIn post. Use when the user finds a post they want to learn from — paste the URL and get a structural breakdown. Identifies which of the 10 canonical 2026 formulas it uses (anaphora, R.I.P. obituary, year-over-year pivot, time-anchor confession, self-proving meta, odd-precision money, paid-vs-free reversal, curiosity-gap, contrarian historical, comment-gate). Returns a blank template you can fill with your own voice. Keywords: hook formula, viral teardown, reverse engineer, post structure, 2026 formulas.

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 (Jake Ward, Lara Acosta, etc.)
  • 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-F10 from
    linkedin-post-writer/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
  • Cautions: anything in the original post that would fail 2026 audit (em dashes, AI vocab, outdated tactics)

Steps

  1. Parse URL.
    lib.url_parser.parse_linkedin_url
    post_urn
    .
  2. Fetch post body. HarvestAPI preferred; fall back to asking user to paste text.
  3. Classify. Match against the 10 formulas using features:
    • First 2 lines: anaphoric? question? confession? number-led?
    • Body: numbered list? dated receipts? ledger? teardown?
    • Close: mirror question? identity reframe? commitment?
  4. Score confidence. If multiple formulas fit, return top 2 with fit scores.
  5. Extract structure. Pull each logical section and label it by formula role.
  6. Generate blank template. Replace specifics with
    {slot}
    markers that match the user's topic.
  7. Audit the source. Flag any AI tells in the original so the user doesn't copy them.

Example

Input:

https://www.linkedin.com/posts/dharmesh_every-b2b-software-company-is-or-should-activity-7448808898326654978-iW20

Output:

  • Formula: F10 Contrarian + Historical Receipts (confidence 0.72). Secondary: F5 Self-Proving Meta (0.28).
  • Hook (first 210 chars): "Every B2B software company is (or should be) building an agentic version of their product."
  • Body: single bold claim → 3 paragraphs of reasoning → specific list of product changes required
  • Close: implicit call to action ("Seen this play out in your market yet?")
  • Blank template:
    Every {category} {bold claim}.
    
    {Reasoning paragraph 1 — the forcing function}
    {Reasoning paragraph 2 — what it requires}
    {Reasoning paragraph 3 — what breaks if you don't}
    
    {Closing question that invites reader to take a side}
    
  • Cautions: none (post is clean)
