Turn a topic, blog URL or transcript into a 5–15 post X (Twitter) thread, then ship it in a way the PostOnce X MCP supports (lead tweet plus replies to paste, one Premium long post, or standalone tweets over several days). Use when the user asks for a Twitter thread, an X thread, a thread generator, or to turn an article, video or notes into a thread.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 3 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈3

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common

  • Very specific
  1. Distinctive:

    Write a thread that people read to the end.

    line 11
  2. Distinctive:

    Every post under 280 characters (count emoji as 2).

    line 27
  3. Distinctive:

    Don't tell the user the thread was posted as a thread.

    line 40

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

X (Twitter) thread generator

Write a thread that people read to the end. Be clear up front: the PostOnce MCP publishes single posts. It can't publish a thread as a reply chain, so every thread ends with a publishing choice (below).

Before writing

Get: the source (topic, blog URL, transcript or notes), the account and its voice, who the thread is for, and the one promise the thread makes. If the source is a URL you can read, pull the specific steps, numbers and examples from it. Never invent numbers, results or quotes.

Structure

PostJob
1. HookThe promise and why to keep reading: a result, a list count or a strong claim. Must work alone.
2Context or proof: why you're worth listening to on this, in one or two lines.
3 to N-1One point per post. Numbered if it's a list. Each post makes sense if read alone.
LastThe takeaway in one line, plus one ask: follow, read the full post, or reply.
  • 5–15 posts. Cut any post that repeats another.
  • Every post under 280 characters (count emoji as 2). Aim for 150–260.
  • Short lines, concrete examples, one screenshot or chart where it proves a point.
  • No "1/" filler in the hook; numbering like "1/9" is optional and only if the user likes it.
  • Links go in the last post. Hashtags: none, or one in the last post.

Publishing choices

Offer these, in this order, and let the user pick:

  1. Lead post now, rest by hand. Publish or schedule post 1 with create_post. Give the user the remaining posts, numbered, to paste as replies in the X app right after it goes live. Use get_post to hand them the live URL.
  2. One long post (X Premium only). If the account had X Premium when it was connected, collapse the thread into a single post of up to 4,000 characters: keep the hook as the first lines, turn each post into a short paragraph or list item. Text over 4,000 is cut off, so count it.
  3. Standalone tweets over several days. Rewrite each strong point so it stands alone without "as I said above", then schedule them as separate posts (for example one a day) with publish_at. Good for evergreen material.

Don't tell the user the thread was posted as a thread. It wasn't.

Output

Return the thread as a numbered list with each post's character count, then the recommended publishing choice and why. On approval, follow the postonce skill: confirm the X account and times (with timezone) before calling create_post, then report each post's status with get_post.
