Tweet Thread Builder

Tweet Thread Builder is a skill for Claude Code, Codex from SkillMedev/content-marketing-engine. It costs 102 tokens per session (1,388 once invoked), scanned A, a copy of Tweet Thread Builder, MIT.

A writing aid for turning one idea into a sequence of connected posts on X, formerly called Twitter. It creates a strong first post, gives each later post one step of the explanation, and leads to one chosen action.

In plain words
What is it for?
Use it to build a thread from one concrete story or idea, create hook variations, organize supporting evidence, and end with one call to action such as following, opening a link, or replying.
Why use it?
It helps prevent threads from starting vaguely, spreading a thin idea across too many posts, or hiding the main payoff behind a long introduction. It also keeps the thread focused on one reader takeaway.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Tweet Thread Builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tweet Thread Builder

Threads live or die on the first post: 90%+ of potential readers see only the hook, so a mediocre hook wastes every good post behind it. The costly mistake is spreading one thin idea across fifteen posts or burying the payoff behind "a thread 🧵" with no substance. Earn each scroll.

Operating procedure

Step 1: Gather inputs

  1. The single idea or story - one sentence. If the user gives several, pick the one with the most concrete specifics (numbers, names, before/after); park the rest.
  2. The payoff for the reader: what they know or can do after reading.
  3. Proof material: numbers, screenshots, examples. A thread without at least two concrete specifics is an opinion, not a thread - send the user back for material.
  4. The one CTA (default: follow; alternatives: a link, or "reply with your version").

Label any number the user estimates as an estimate.

Step 2: Write the hook (post 1) - and an A/B pair

  • Promise a specific payoff: a number, a transformation, a contrarian take.
  • No preamble. The first line is the whole pitch. Keep the hook under 200 characters - dense hooks read as work.
  • Proven patterns: "I did X for N days. Here's what happened." / "Everyone believes X. They're wrong." / "N lessons from [hard thing]:"

Always draft two hooks with different mechanisms so the user can pick or test:

  • A (curiosity/story): "I deleted 80% of our landing page. Signups went up 34%. What we removed:"
  • B (contrarian/claim): "Long landing pages are killing your signups. We cut ours to one screen and grew 34%. Proof:"

Same material, different bet: A sells the mystery of what was removed; B sells the argument. Pick A for story-driven audiences, B when the take itself is polarizing enough to drive replies.

Step 3: Outline the beats

  • One idea per post. If a post has two ideas, split it. If two posts share one idea, merge them.
  • 5-12 posts is the sweet spot. Under 5, make it a single tweet; over 12, cut - every post past 12 sheds readers faster than it adds value.
  • Order the beats so each ends on a small open loop that the next post resolves; momentum is the structure.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
