What it does
X Hook Extractor is an agent skill from sergebulaev/x-skills. 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).
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/classification-rules.md` and `references/examples.md`).
It sits in Writing & Content, covering Social media posts. It works with X (Twitter). The repository describes itself as: X (Twitter) marketing skills for Claude Code and Codex: write tweets, threads, and replies in your voice, strip AI tells, and publish via Publora. Open source, MIT. Content… The licence is MIT.
When your agent uses it
- Learn from a tweet you admire
- Tasks that involve Social media posts
Example prompts
- “/x-hook-extractor”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Parse the URL. lib.url_parser.parse_x_url(url) returns handle,
- Get the text. This bundle has no built-in tweet reader, so ask the user to
- Detect the container. One self-contained tweet, or a multi-tweet thread.
- Classify against the 11 formulas using features
- 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
- Name the primary goal the original optimized for.
- Generate a blank template with {slot} markers matched to the original
- Audit the source. Flag any AI tells in the original so the user does not
What it can do on your machine
Read from SKILL.md and the folder at commit 6ffd8e0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
X Hook Extractor loads about 964 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 128 tokens; SKILL.md has 478 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- x-hook-extractor
- description
- 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 (more than one em dash in a tweet, an AI-vocab cluster, 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.
