This tool is a Claude skill that transforms raw text, scripts, or screenshots into algorithm-optimized captions for seven major social media platforms. It acts as an AI writing assistant specifically designed to improve post reach and engagement for content creators.
Security Assessment
Overall risk: Low. The repository requests no dangerous system permissions and does not appear to execute arbitrary shell commands. It operates as a local prompt/skill extension for Claude Code rather than functioning as a standalone script that makes external network requests. There are no obvious hardcoded secrets or data-harvesting mechanisms. The primary data processed consists of your own text inputs and social media scripts, which are sent to your local Claude environment to generate the responses.
Quality Assessment
The project is active, with its most recent code push happening today, and it is protected by a standard MIT license. It demonstrates reasonable community trust with 41 GitHub stars. However, a code scan was incomplete because no supported source programming files were detected. Because of this, the tool is likely built purely from Markdown prompt files rather than compiled code. While this structure is completely standard for a Claude skill, the inability to scan the underlying logic means you are trusting the author's prompt design. Ultimately, it is a well-documented tool created by an established social media creator.
Verdict
Safe to use, provided you are comfortable passing your content drafts into your local AI environment.
Social media caption generator as a Claude skill — turn any text, script, or screenshot into ready-to-post captions for Instagram Reels, Carousel, TikTok, Threads, Facebook, YouTube Shorts. Algorithm-optimized for shares, saves, and completion rate. Built by @roman.knox (280K+ IG).
Social Media Caption Generator — Claude Skill
Social media caption generator for Claude Code. Turn any text, script,
screenshot, or competitor post into ready-to-post captions for all 7 major
platforms — optimized for the signals each algorithm actually rewards.
This is the actual Claude skill I use to caption every post on @roman.knox (280K+ followers).
One prompt in. Captions for Instagram, TikTok, Threads, Facebook, YouTube Shorts out.
What it does
Send it anything:
- A script or raw notes
- A screenshot or image of your post
- A competitor's viral post (it'll write something better)
- A brief description of your content
- A link to an article you're repurposing
You get back ready-to-copy captions for 7 formats, each using a different proven formula:
- Instagram Reels — hook-first, optimized for DM shares
- Instagram Carousel — longer, save-optimized
- TikTok — 80-char hook, completion-rate language
- Threads — conversation starter, reply-optimized
- Facebook Page/Personal — trigger-word-free for max reach
- Facebook Group — community tone, discussion question
- YouTube Shorts — title + description, search-keyword-optimized
Each caption comes with a breakdown: formula name, hook type, CTA type, and which algorithm signal it optimizes for.
Why every platform needs a different caption
Most creators copy-paste the same caption to every platform. That's why their reach dies on 6 of the 7.
Every algorithm rewards different signals in 2026:
| Platform | #1 signal | Dead signal |
|---|---|---|
| Instagram Reels | DM shares | Likes |
| Instagram Carousel | Saves | Likes |
| TikTok | Completion rate (70%+) | Hashtag spam |
| Threads | Replies | Cross-posted content |
| Facebook Page | 40-80 char posts | Trigger words (-70% reach) |
| Facebook Group | Discussion questions | Links |
| YouTube Shorts | Title SEO + retention | Clickbait |
This skill bakes all of that into the output. No #fyp. No #viral. No engagement bait. No Facebook trigger words. No copy-paste.

cd ~/.claude/skills/gstack
git clone https://github.com/rediumvex/social-media-caption-generator-claude.git social-captions
Usage
Just send Claude the material — it figures out the rest:
/social-captions here's my reel script: [paste script]
/social-captions [paste screenshot of your carousel]
/social-captions competitor post crushing right now: [url or text]
/social-captions topic: "how to use Claude skills for SEO blog posts"
You get back all 7 platforms, each with:
- Ready-to-paste caption text
- 3-5 niche hashtags (never generic)
- Formula breakdown
- Hook type
- CTA type
- Signal being optimized
Then you pick, tweak, post.
What's inside (highlights)
The skill encodes the full 2026 algorithm playbook:
- 30+ caption formulas across reach, engagement, sales, and growth goals
- Hook library — provocation, curiosity, value, emotion, TikTok-specific
- Platform-specific length rules (IG Reels 80-200 chars, FB Page 40-80, TikTok 100-300, etc.)
- Anti-patterns — engagement bait, shadow ban triggers, format crimes
- Power words library by category (urgency, trust, exclusivity, emotion)
- Facebook trigger word replacements — "FREE" → "complimentary", etc.
- Signal hierarchy — shares > saves > comments > watch time > likes
All based on what's actually shipping results in 2026, not 2020 best practices.
Who built this
I'm Roman Knox. I run the Instagram @roman.knox — 280K+ followers posting daily about AI, Claude Code, n8n, and automation.
I built this skill because I was spending 30 minutes per post writing captions for each platform separately. Now it's one prompt, 7 platforms, done.
