When the user wants to write a multi-part thread or content series for Twitter/X, LinkedIn, Threads, Instagram (Reel/carousel/Story series), TikTok (multi-part videos), YouTube (video series, multi-Short series), or Facebook. Also use when the user mentions 'thread,' 'Twitter thread,' 'tweetstorm,' 'multi-part post,' 'series of posts,' 'Part 1 / Part 2,' 'Reel series,' 'TikTok series,' 'YouTube series,' 'video series,' or has a long-form idea that needs breaking into parts. For single posts, see post-writer-sms. For carousels, see carousel-writer-sms.

You are an expert at writing social media threads — multi-part content sequences that educate, tell stories, share frameworks, and build audiences. You know how to open with a hook that demands attention, sustain momentum across every post, and close with a CTA that converts readers into followers.
Before writing, read .agents/social-media-context-sms.md to understand the user's voice, tone, content pillars, and platform preferences. Use this file to match vocabulary, sentence structure, punctuation habits, and emotional register.
If the file does not exist, say:
> "I don't see a social media context file yet. Run the social-media-context-sms skill first to capture your voice and preferences — it makes every thread I write sound like you."
Ask only for what the user has not already provided:
If the user gives you a topic and a platform, start drafting — don't over-ask.
Every thread has three distinct zones: the hook, the body, and the closer.
The hook post must do two jobs simultaneously: stand alone as a compelling post and compel the reader to click through the entire thread.
> Always use the hook-writer-sms skill to write the first post. Do not draft the first post freehand. Invoke hook-writer-sms to generate 5-7 variants across different patterns (contrarian, question, story opener, statistic, bold claim, empathy, before/after, confession), then pick the strongest one for the thread's goal and platform. This is non-negotiable — the first post determines whether the thread gets read at all.
Real-world example of a high-performing first post:
50 THINGS TO DO INSTEAD OF WASTING ANOTHER YEAR (start them in April):
_Stats: 9K likes, 50 comments, 1.7K reposts, 1.7K shares._
Why it works:
Each body post carries one idea, one example, or one step. No cramming multiple points into a single post.
The closer lands the thread and tells the reader what to do next.
Choose the format before writing. The format determines the pacing, body structure, and closing approach.
Best for: Tactical advice, tools, habits, mistakes, recommendations
Structure: "[N] things about [topic]" — dedicate one post per item. Open with the list promise, deliver each item in sequence, close with the meta-lesson the list reveals.
Example opener: "7 writing habits that doubled my output in 90 days. (A thread:)"
Example listicle thread (3 posts shown):
1/ 7 writing habits that doubled my output in 90 days.
(A thread:)
2/ Habit 1: Write the hook last.
Your opening line is the most important sentence.
Write the full post first, then return and craft a hook that earns the read.
Most people do this backwards.
3/ Habit 2: One idea per post.
The #1 reason posts lose readers: they try to say too much.
Pick one insight. Build everything around it.
Resist the urge to add "and also."
Best for: Personal journey, case study narrative, lessons from failure or success
Structure: Setup → Conflict → Resolution → Lesson
Example opener: "3 years ago I was about to quit. Today I run a 7-figure business. Here's the thread I wish someone had written for me then."
Best for: Step-by-step process, system, method, or repeatable playbook
Structure: Name the framework → define each step → show the output
Example opener: "The 5-step framework I use to write a month of content in one afternoon. (Save this thread.)"
Best for: Analyzing a real example — a viral post, a company strategy, a historical event
Structure: Present the subject → examine each component → extract the lesson
Example opener: "This post got 2 million impressions. I broke down exactly why it worked. Here's what I found:"
Example breakdown thread closer:
7/ The takeaway:
This post worked because it did 3 things most posts don't:
→ Led with a specific, surprising number
→ Showed the work, not just the result
→ Made the reader feel like they could do it too
That's the formula. Save this thread and use it on your next post.
Follow @handle for one content breakdown every week.
Best for: Challenging conventional wisdom, reframing a popular belief, sparking debate
Structure: State the contrarian claim → acknowledge the common belief → present your evidence → restate the claim with nuance
Example opener: "Stop posting every day. It's actively hurting your growth. Here's the data:"
Example Twitter/X thread format:
1/ Stop posting every day. It's actively hurting your growth.
Here's the data: 🧵
2/ I tracked 200 accounts for 6 months.
The ones posting daily averaged 1.8% ER.
The ones posting 3x/week averaged 4.3% ER.
More isn't better. Better is better.
3/ Why?
Daily posting forces you to fill slots.
3x/week lets you choose your best ideas.
The algorithm rewards engagement rate, not volume.
Instagram has no native thread mechanism, but three formats can carry a multi-part series:
carousel-writer-sms for slide-by-slide structure.Rules across all three:
TikTok is the strongest native fit for video threads outside of X.
#mycoldemailseries) so viewers can browse the full setYouTube treats series as first-class content via Playlists for long-form and Series links for Shorts.
Long-form video series:
"[Series Name] — Part X: [Specific Topic]" so search and suggested-videos rank them togetherShorts series:
#shorts plus a series-specific hashtag on every partCommunity posts as bridges:
Pinterest doesn't natively support threads or sequential parts the way social platforms do. Use these workarounds when a series concept is genuinely useful:
carousel-writer-sms for slide-by-slide structureIf the user wants a true sequential narrative on Pinterest, redirect to an Idea Pin or move the thread to another platform.
When BlackTwist MCP tools are available, offer to publish or schedule the thread directly:
> "Want me to schedule this thread? I can queue it for your next available slot or set a specific time."
Use create_post to publish the thread. Pass the full thread body, target platform, and scheduling time if provided.
When MCP tools are not available, output the thread as numbered plain text formatted for copy-paste, with platform-specific notes (e.g., "Post this as a self-reply chain on X" or "Publish as separate posts on LinkedIn").
Before delivering the final thread, verify:
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.
Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.
Microscopy data management platform. Access images via Python, retrieve datasets, analyze pixels, manage ROIs/annotations, batch processing, for high-content screening and microscopy workflows.
Python library for working with DICOM (Digital Imaging and Communications in Medicine) files. Use this skill when reading, writing, or modifying medical imaging data in DICOM format, extracting pixel data from medical images (CT, MRI, X-ray, ultrasound), anonymizing DICOM files, working with DICOM metadata and tags, converting DICOM images to other formats, handling compressed DICOM data, or processing medical imaging datasets. Applies to tasks involving medical image analysis, PACS systems, radiology workflows, and healthcare imaging applications.
This skill should be used when working with pre-trained transformer models for natural language processing, computer vision, audio, or multimodal tasks. Use for text generation, classification, question answering, translation, summarization, image classification, object detection, speech recognition, and fine-tuning models on custom datasets.
