What its author says it does
Copied from the file, not written here
Reverse-engineer the hook from a viral X (Twitter) tweet or thread URL. Identifies which of the 10 canonical 2026 X formulas it uses (one-liner contrarian, data-point, build-in-public, quote-tweet, mini-list, relatable cold-open, listicle-thread, story thread, curiosity-gap, how-I teardown), explains why it worked, and returns a blank template mapped to your topic with its primary goal. Use to learn from a tweet you admire. Not for writing your own (use x-post-writer or x-thread-builder).

X Hook Extractor
Paste a viral tweet or thread URL. 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 viral tweet or thread they want to study
- User wants to replicate a specific creator's pattern
- Before
x-post-writerorx-thread-builder, to seed a draft with a proven shape
Input
An X tweet or thread URL (x.com or twitter.com, /status/<id>). For a thread,
the URL of the first tweet is best.
Output
- Formula identified (X1-X10 from
../../references/hook-formulas.md) with a confidence score - Container: single tweet vs thread, and why that container fit the idea
- Structural breakdown:
- The hook line (and for a thread, how tweet 1 opens the loop)
- Body architecture (per-tweet roles for a thread)
- The close (what earns the repost or bookmark)
- Reaction-triggering devices (numbers, named entities, the open loop)
- Primary goal the original chased (replies / reposts / likes / bookmarks)
- Why it worked psychologically and algorithmically
- Blank template with
{slot}markers matched to the original, ready for the user's topic - Cautions: anything in the original that would fail a 2026 audit (em dashes, AI vocab, 3+ hashtags, link in tweet 1)
Steps
- Parse the URL.
lib.url_parser.parse_x_url(url)returnshandle,tweet_id,url_type. - Get the text. This bundle has no built-in tweet reader, so ask the user to paste the tweet or the full thread text. (If they later wire an Apify tweet actor, read it automatically.)
- Detect the container. One self-contained tweet, or a multi-tweet thread.
- Classify against the 11 formulas using features:
- Single tweet: a flat contrarian claim (X1)? one hard number (X2)? a personal metric/confession (X3)? a quote tweet adding a layer (X4)? a one-line-per- item list (X5)? a relatable shared moment (X6)?
- Thread: a numbered teaching promise (X7)? a story starting at the tension (X8)? a surprising result with the mechanism withheld (X9)? a first-person "how I" teardown (X10)?
- Score confidence. If two formulas fit, return the top 2 with fit scores.
- Extract structure. Label each part by its role. For a thread, map tweet 1 (the loop), the front-loaded payoff, the body beats, and the closer.
- Name the primary goal the original optimized for.
- Generate a blank template with
{slot}markers matched to the original shape and the user's topic. - Audit the source. Flag any AI tells in the original so the user does not copy them.
