What it does

X Repurposer is an agent skill from sergebulaev/x-skills. Repurpose existing content into a native X (Twitter) post or thread. Take a LinkedIn post, blog, YouTube script, or newsletter and rewrite it for X: re-hook for the no-fold first line, refit to 280 chars or a thread, strip off-platform artifacts, run the humanizer, publish via Publora on approval. Not for writing from scratch (use x-post-writer or x-thread-builder), not for auditing a draft (use x-humanizer --mode audit).

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Social media posts, Content repurposing and Humanizing AI text. It works with X (Twitter) and LinkedIn. 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.

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

    Hosts in commands or code, which the agent is likely to contact:

    • x.com

    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 Repurposer loads about 1.7k tokens when it runs. Until then it costs about 110 tokens; SKILL.md has 942 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

description
Repurpose existing content into a native X (Twitter) post or thread. Take a LinkedIn post, blog, YouTube script, or newsletter and rewrite it for X: re-hook for the no-fold first line, refit to 280 chars or a thread, strip off-platform artifacts, run the humanizer, publish via Publora on approval. Not for writing from scratch (use x-post-writer or x-thread-builder), not for auditing a draft (use x-humanizer --mode audit).

X Repurposer

Turn something you already made into a tweet or thread that reads like it was born on X. Repurposing is not copy-paste. A post that killed on LinkedIn will die on X if you paste it: wrong hook, wrong length, wrong rhythm, and artifacts ("link in bio", hashtag walls) that scream off-platform.

This skill transforms, it does not generate. It reads your source, keeps the idea, and rebuilds the delivery for X.

When to use

  • "Turn this LinkedIn post into a tweet / thread"
  • "Repurpose my blog post / newsletter / YouTube script for X"
  • "This worked on Threads, adapt it for X"
  • "I have a rough idea in another format, make it native here"

Not for a blank-page draft (use x-post-writer for a tweet, x-thread-builder for a thread) and not for reviewing an already-X draft (use x-humanizer --mode audit).

How it works

Voice profile first (all drafts). If ../../references/voice-profile.md has filled: yes, load it and match the user's voice fingerprint, hard rules, and CTA/link style throughout. If it is not filled, mention once that x-humanizer --mode profile can learn their voice from a few posts, then proceed with the generic voice rules.

Story bank next. If ../../references/story-bank.md has filled: yes, load it and take every concrete detail (numbers, dates, named projects, positions) from there instead of asking mid-draft. Never invent a figure, a date or a client name that is not in the bank or supplied by the user in this conversation. If the bank has nothing that fits, ask the user, or say once that x-humanizer --mode interview fills it in 20 to 40 minutes. A draft with a plausible invented number is worse than a draft with none: one is vague, the other is a retraction.

  1. Take the source. Any format: a post, a paragraph, a script, a caption, a transcript, a bullet list, a link to read. Ask for the source and the goal (replies / reposts / likes / bookmarks) if not given.
  2. Extract the spine. Strip the source platform's shell and pull out the one claim, the one story, or the one number worth keeping. Most repurposing fails because it keeps the words instead of the point.
  3. Choose the container. One claim or number -> single tweet. A teach or a build -> thread (hand structure to x-thread-builder's shapes). A LinkedIn carousel or a listicle -> a thread, one slide per tweet, hook rebuilt. A long video -> a thread that delivers the payoff, not a summary.
  4. Re-hook for X. X has no "see more" fold: line one must land the whole punch. The source's hook almost never survives; write a new first line using a 2026 X formula (see ../../references/hook-formulas.md), picked by the goal.
  5. Refit the format. 280 chars on a standard account (emoji count as 2). One idea per tweet, line breaks as beats. Cut the source's connective tissue; X rewards compression.
  6. Strip off-platform artifacts. Remove "link in bio", "smash subscribe", "read more below", hashtag walls, @-handles that only exist elsewhere, and any "as I wrote on LinkedIn" throat-clearing. A repurposed post should not admit it was repurposed.
  7. Humanizer pass. Run the scrub: 2026 AI vocab by density, em dashes above the cap (at most one per tweet, never swapped for a period), stacked rule-of-three triads, generic openers and reveal bridges. Leave a single tweet's rhythm alone; on a thread never insert a punch tweet for variance. Keep the user's real numbers and named entities from the source. Canonical rules: x-humanizer V3.
  8. Approval card. Show: source -> X mapping (what became what), the container (tweet or N-tweet thread), formula used, char counts, primary goal.
  9. On approval. Publish via lib.publish(kind="post", draft_text=<approved>, target_url="https://x.com/compose/tweet", platforms=[<X_PLATFORM_ID>], scheduled_time=<iso_or_None>). Publora auto-splits an over-length draft into a numbered thread.

Native-fit rules (source -> X)

  • LinkedIn post -> X: cut ~40%. LinkedIn tolerates warm-up; X does not. The LinkedIn hook is usually too long; rewrite it.
  • Blog / newsletter -> X: pick the single most quotable claim as the hook, then thread the supporting beats. Do not summarize the whole piece.
  • YouTube script -> X: lead with the video's payoff, not its intro. "Here's what I found" beats "In this video".
  • Carousel / listicle -> thread: one item per tweet, each with its own micro-hook, not a wall.
  • Instagram / TikTok caption -> X: strip emoji density and hashtag blocks; X reads them as noise.

Hard rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

  • Keep the source's claim and facts intact. Repurposing changes the delivery, never the meaning or the numbers.
  • The new first line must stop the scroll on its own. If it needs line two, rewrite it.
  • Never paste the source verbatim and trim. Rebuild the hook and rhythm from the spine.
  • One specific number where the source offers one. Keep it.
  • Do not hard-sell the user's product. One natural mention max.

Anti-patterns (skill will refuse)

  • Copy-pasting the source with light edits (that is not repurposing).
  • Keeping the source platform's artifacts ("link in bio", "smash subscribe", hashtag walls).
  • ALL CAPS first line for intensity. Carry it with word choice.
  • Em dashes above the cap (more than one in a tweet), or an em dash swapped for a period.
  • "The result?" / "Here's what" reveal bridges and staccato stacks added during the rewrite.
  • Rule-of-three lists without specifics.
  • "leverage", "fundamentally", "game-changer", "deep dive".
  • An external link in the tweet body (offer a reply).
  • Meta throat-clearing ("I originally posted this on...").

Resources

  • ../../references/hook-formulas.md - the 11 X formula skeletons to re-hook with
  • ../../references/algorithm-heuristics.md - 2026 X ranking rules (length, timing, signals)
  • x-post-writer - write a fresh tweet from scratch
  • x-thread-builder - structure a multi-tweet thread (repurposer hands long builds here)
  • x-humanizer - scrub AI tells, plus --mode audit to review the result
