X (Twitter) Marketing Skills for Claude Code and Codex

Part of the linkedin-skills family (400+ stars). Same voice engine and approve-before-publish flow, now for X. Also available for Instagram · YouTube · TikTok · Threads · Facebook.

9 skills that turn Claude Code and Codex into your X (Twitter) content team. They write tweets and threads in your voice with corpus-validated hooks, extract the hook from any viral tweet, draft replies and quote tweets, and plan a week of content. Every draft gets the AI tells stripped and waits for your approval before anything publishes. No coding required.

Once installed, just ask Claude Code or Codex things like:

• "Write a tweet about [topic]"
• "Turn these notes into a thread"
• "What's working in my niche on X right now? (reads real data via Apify)"
• "Rewrite this tweet so it doesn't sound like AI"

The right skill activates automatically. Then you review and approve.

What you can do

Once installed, just ask Claude Code or Codex for help with X. The right skill activates automatically.

Write a tweet:

"Write me a tweet about why most AI agents fail on retries, not reasoning. Make it sharp."

Turn an idea into a thread:

"Turn my notes into a thread on how we cut agent latency from 9s to 2.1s."

Check a draft before posting:

"Audit this tweet for AI tells and the 280-char limit: [paste your text]"

Reverse-engineer a viral tweet:

"What hook does this thread use? https://x.com/someone/status/123 (I'll paste the text)"

Reply to a creator:

"Draft a reply to this tweet, I want to add value not dunk: https://x.com/someone/status/123"

Plan your week:

"Plan a week of X content. I'm building an AI agent in public for indie devs."

Every skill shows you a draft first and waits for your OK. Nothing gets posted without your approval.

The 9 skills

Skill	What it does
Post Writer	Drafts a single tweet (or short auto-thread) using a 2026 X hook formula picked by goal: replies, reposts, likes, or bookmarks. Respects the 280-char limit (25,000 on Premium)
Thread Builder	Builds long-form tweetstorms (listicle, story, curiosity-gap, how-I teardown). Structures tweet 1 as a promise plus open loop, front-loads value, closes for the repost
Humanizer	Removes the AI tells human readers react to: 2026 AI vocabulary scored by density per tweet, reveal bridges, staccato fragment stacks, stacked triads, performed sincerity; caps em dashes at one per tweet instead of banning them, and never forces rhythm on a single tweet (uniform rhythm wins on short posts). Does not promise to beat detectors (no edit reliably does). Bundles a --mode audit pre-publish check (280-char fit, hook, hashtags, link placement)
Hook Extractor	Reverse-engineers the hook from any viral tweet or thread. Maps it to one of the 11 X formulas and returns a blank template you can fill
Reply Drafter	Drafts a reply or a value-add quote tweet for any tweet URL. Decides reply vs quote tweet. X has no LinkedIn-style thread flattening, so a reply is just a tweet
Content Planner	Creates a weekly plan with a single-to-thread mix, per-day hook
