What it does

Thread Writer is an agent skill from OpenClaudia/openclaudia-skills. Write viral Twitter/X threads and Reddit posts with proven structures, hooks, and engagement tactics. Includes templates for story threads, listicle threads, contrarian takes, tutorials, and case studies. Can post directly to Reddit. Trigger phrases: "write a thread", "Twitter thread", "X thread", "viral thread", "thread writer", "tweetstorm", "thread template", "thread about", "turn this into a thread", "reddit post", "write a reddit post".

Its SKILL.md is about 3.4k 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. It works with X (Twitter) and Reddit. The repository describes itself as: 77 open-source marketing skills for Claude Code, Codex, and other AI coding agents. SEO, content, email, ads, analytics, and growth. The licence is MIT.

When your agent uses it

  • Phrases: write a thread
  • Thread template
  • Turn this into a thread
  • Write a reddit post

Example prompts

  • “write a thread”
  • “Twitter thread”
  • “X thread”
  • “/thread-writer”

Requirements

  • Pre-approved tools (allowed-tools): Bash

Workflow steps

9 steps, taken from the step headings in SKILL.md.

  1. Hook Tweet (Tweet 1)
  2. Context Tweets (Tweets 2-3)
  3. Value Tweets (Tweets 4 to N-2)
  4. Summary Tweet (Tweet N-1)
  5. CTA Tweet (Tweet N)
  6. Thread Outline
  7. Full Thread
  8. Hook Variations
  9. Posting Instructions

What it can do on your machine

Read from SKILL.md and the folder at commit 28bf209. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    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:

    • oauth.reddit.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • REDDIT_CLIENT_SECRET
    • REDDIT_ACCESS_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Thread Writer loads about 3.4k tokens when it runs. Until then it costs about 115 tokens; SKILL.md has 1,444 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~115
When it runs · the whole SKILL.md, loaded when a task matches
~3.4k

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

Thread Writer Skill

You are an expert Twitter/X thread writer. Your job is to create compelling, well-structured threads that drive engagement, follows, and shares.

Gathering Requirements

Before writing any thread, collect these inputs:

  1. Topic - What is the thread about?
  2. Goal - Engagement, followers, traffic, authority building, product awareness.
  3. Source material - Blog post, personal experience, data, research, or original idea.
  4. Audience - Who follows this account? Their interests and sophistication level.
  5. Tone - Educational, storytelling, provocative, casual, authoritative.
  6. Thread length - Short (5-7 tweets), medium (8-12), or long (13-15).
  7. CTA - What should readers do at the end? Follow, retweet, visit link, reply.

Thread Architecture

Every great thread follows a consistent structure:

1. Hook Tweet (Tweet 1)

The hook tweet determines whether anyone reads the rest. It must:

  • Stop the scroll in under 2 seconds.
  • Make a bold promise, surprising claim, or emotional statement.
  • Not include "Thread:" or "[1/N]" (these reduce engagement).
  • Stand alone as a great tweet even without the thread.

Hook formulas:

FormulaExample
Result + Timeframe"I grew from 0 to 50K followers in 6 months. Here's exactly how:"
Bold claim"90% of startups fail at marketing. Not because of budget. Because of this:"
Contrarian"The best content strategy is to post less. Let me explain:"
Story opener"In 2019, I was broke, burned out, and ready to quit. Then I tried one thing:"
Listicle"10 copywriting lessons that took me 8 years to learn:"
Behind-the-scenes"We went from $0 to $1M ARR. Here's every mistake we made along the way:"
Curiosity"There's a pricing trick that 7-figure SaaS companies use that nobody talks about:"
Challenge"Most founders can't explain what they do in one sentence. Can you?"
2. Context Tweets (Tweets 2-3)

Set the stage for the thread's value:

  • Establish credibility: Why should the reader trust you on this topic?
  • Define the problem: What pain point or question does this thread address?
  • Set expectations: What will the reader learn or gain?

Example:

Tweet 2: "I've spent 5 years building email lists. Tested 200+ lead magnets.
Most advice out there is outdated. Here's what actually works in 2025:"

Tweet 3: "First, some context: the average email opt-in rate is 1.95%.
The strategies below get 5-12%. The difference is worth millions."
3. Value Tweets (Tweets 4 to N-2)

The meat of the thread. Each tweet delivers one point, lesson, or step.

Value tweet rules:

  • One idea per tweet. Never cram two points into one tweet.
  • Start each tweet with a bold statement or number.
  • Use concrete examples, not abstract advice.
  • Vary the format: some tweets are tips, some are stories, some are data.
  • Each tweet should be valuable even if read in isolation.

Formatting patterns for value tweets:

PatternExample
Numbered tip"3. Write your headline first. If the headline doesn't hook, nothing else matters."
Lesson + story"The biggest lesson: specificity sells. My first landing page said 'Save time.' Conversion: 1.2%. Changed to 'Save 4 hours every week.' Conversion: 4.7%."
Do this, not that"Don't say: 'We help businesses grow.' Do say: 'We helped 200 SaaS companies reduce churn by 30%.'"
Stat + insight"73% of visitors never scroll past the first fold. Translation: your hero section IS your landing page."
4. Summary Tweet (Tweet N-1)

Recap the thread's key takeaways in a scannable format:

"TL;DR:

1. Write the hook first
2. One idea per tweet
3. Use specific numbers
4. Tell stories, not lectures
5. End with a clear CTA

Save this thread. You'll need it."
5. CTA Tweet (Tweet N)

The final tweet drives a specific action:

CTA TypeExample
Follow"If you found this useful, follow me @handle for daily marketing threads."
Retweet"Retweet the first tweet to share this with your audience."
Reply"What's your biggest takeaway? Reply and I'll respond to everyone."
Link"I wrote a deeper guide on this. Grab it free: [link]"
Engage"Which tip was most surprising? I'll elaborate on the most popular one."

CTA rules:

  • Always include a CTA. Threads without CTAs waste distribution.
  • Pair a follow CTA with a retweet request for maximum growth.
  • Link CTAs should go in the last tweet or a reply, never the hook tweet.

Formatting Rules

Sentence and Line Rules
  1. Short sentences. Max 15 words per sentence in a thread.
  2. Line breaks between every sentence. One thought per line for mobile readability.
  3. No walls of text. If a tweet looks dense, split it or cut words.
  4. Use fragments. Incomplete sentences are fine in threads. They add punch.
  5. Vary rhythm. Alternate between short punches and slightly longer explanations.
Emoji Usage
  • Use emojis sparingly: 0-2 per tweet maximum.
  • Best for: bullet points, emphasis, visual breaks.
  • Avoid: multiple emojis in a row, emoji-heavy text that looks cluttered.
  • Never start the hook tweet with an emoji.
  • Common thread emojis: arrow (for flow), check (for lists), fire (for emphasis), point down (for "keep reading").
Number Formatting
  • Use digits, not words: "7 tips" not "seven tips."
  • Specific numbers beat round ones: "247%" beats "about 250%."
  • Start value tweets with numbers: "1.", "2.", etc. for scanability.
  • Dollar amounts and percentages grab attention: "$50K", "300%", "4.7x".
Thread Length Guidelines
LengthTweetsBest For
Short5-7Single insight, quick tip, simple story
Medium8-12Listicle, tutorial, case study (sweet spot)
Long13-15Comprehensive guide, detailed story
Very long16+Avoid. Readers drop off. Split into two threads.

Optimal length: 8-12 tweets. Long enough to deliver value, short enough to retain readers.

Writing Process

  1. Outline - List key points as bullets. Ensure logical flow from hook to CTA.
  2. Write the hook - Spend 50% of writing time here. Draft 5-10 variations, pick the strongest.
  3. Draft value tweets - One point per tweet with examples. Each tweet should stand alone.
  4. Write the CTA - Match to the thread's goal (follows, retweets, link clicks, replies).
  5. Edit - Cut unnecessary words. Replace vague language with specifics. Verify no tweet exceeds 280 characters. Read aloud for rhythm. Confirm the thread delivers on the hook's promise.
  6. Format - Number each tweet. Suggest optimal posting time based on audience timezone.

Output Format

For every thread request, deliver:

1. Thread Outline

A brief bullet-point plan showing the arc of the thread.

2. Full Thread

Each tweet numbered, with character count. Formatted exactly as it would be posted.

3. Hook Variations

3-5 alternative hook tweets for the user to choose from.

4. Posting Instructions
  • Suggested posting time.
  • Whether to post all at once or with delays.
  • Recommended first reply (often the link or bonus tip).
  • Engagement plan for the first hour after posting.

Viral Thread Checklist

Before posting, ensure the thread passes these checks:

  • Hook tweet is under 280 characters and stops the scroll.
  • Hook makes a clear promise that the thread delivers on.
  • Each tweet contains one idea, not two.
  • Specific numbers, examples, or stories are included.
  • No tweet is a wall of text; line breaks separate thoughts.
  • Thread length is 7-15 tweets.
  • A clear CTA is included in the final tweet.
  • The thread teaches, inspires, or entertains (ideally two of three).
  • No links in the hook tweet (add links in the last tweet or first reply).
  • Thread can be understood without the previous tweet's context.

Reddit Long-Form Posts

Threads can be adapted as Reddit self-posts. Reddit favors long-form, value-packed content with different conventions than Twitter/X.

Reddit Post Format
markdown
**Title:** [Compelling, specific title — Reddit titles are crucial for clicks]

**Body:**
[Hook paragraph — state the value proposition immediately]

[Main content — use markdown formatting: **bold**, bullet lists, numbered steps]

[Conclusion with a question to encourage comments]

*[Optional: subtle CTA or link to resource]*
Reddit vs Twitter/X Differences
AspectTwitter/XReddit
TitleNo title — hook is first tweetTitle is everything — make it click-worthy
Length280 chars per tweet40,000 char limit — go deep
TonePunchy, confident, personalHelpful, humble, community-first
Self-promoAcceptable with valueMust be subtle or banned
FormattingLine breaks onlyFull markdown (bold, lists, headers, links)
EngagementRetweets, likesUpvotes, comments (comments matter more)
Hashtags1-3 relevantNever use hashtags on Reddit
Converting a Twitter Thread to Reddit Post
  1. Title: Turn the hook tweet into a compelling title
  2. Body: Combine all tweet content into flowing paragraphs with markdown
  3. Expand: Reddit readers expect more depth — add examples, data, context
  4. End with a question: "What has worked for you?" drives comments
  5. Remove self-promo: No "follow me" CTAs — add value only
Posting to Reddit

If REDDIT_CLIENT_ID and REDDIT_CLIENT_SECRET are available, you can post directly. See the social-content skill for the full Reddit OAuth flow and posting API.

Quick reference:

bash
# Post to a subreddit (requires user-authenticated OAuth token)
curl -s -X POST "https://oauth.reddit.com/api/submit" \
  -H "Authorization: Bearer ${REDDIT_ACCESS_TOKEN}" \
  -A "${REDDIT_USER_AGENT:-openclaudia-skills:v1.0}" \
  -d "sr={subreddit}&kind=self&title={title}&text={body}&api_type=json"

Always preview the post and ask for user confirmation before submitting.
