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 @theromanknox (280K+ followers). One prompt in. Captions for Instagram, TikTok, Threads, Facebook, YouTube Shorts out.
Send it anything:
You get back ready-to-copy captions for 7 formats, each using a different proven formula:
Each caption comes with a breakdown: formula name, hook type, CTA type, and which algorithm signal it optimizes for.
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.

All based on what's actually shipping results in 2026, not 2020 best practices.
I'm Roman Knox. I run the Instagram @theromanknox — 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.
