SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Writing captions that actually perform on visual-first platforms requires knowing each platform's truncation points, hashtag rules, SEO behavior, and CTA conventions. This Skill removes the guesswork by applying platform-specific caption structures so your copy supports the visual instead of fighting the algorithm. ## Core Features & Use Cases - Platform-Native Caption Structures: Applies distinct formats for Facebook, Instagram, TikTok, Pinterest, and YouTube, including character limits, hashtag counts, and link placement rules. - Hook-Payoff-CTA Framework: Builds every caption around a truncation-aware hook, a value payoff, and a platform-appropriate call to action. - Voice Matching: Reads a social media context file to mirror your vocabulary, emoji habits, and sentence rhythm. - Use Case: You have a Reel showing a 30-day experiment result. The Skill writes an Instagram caption with a scroll-stopping first line, save/share CTAs, and 3-10 relevant hashtags, plus a TikTok variant optimized for in-app search. ## Quick Start Ask the assistant to write an Instagram caption for your photo or video, describing the visual, the platform, and the goal you want the caption to achieve.

FAQPage Schema
How do I write an Instagram caption that gets more engagement?

Front-load a hook in the first 125 characters before the truncation point, deliver a payoff that rewards tapping "more," and end with a save or share CTA. Use 3-10 hashtags placed at the end of the caption or in the first comment.

What is the best caption length for TikTok videos?

Most high-performing TikTok captions stay under 150 characters even though the limit is 2200. Treat the caption as searchable text with keywords your audience would type, plus 3-5 hashtags mixing broad and niche tags.

Should I use hashtags in Pinterest pin descriptions?

No, Pinterest hashtags are effectively ignored by the algorithm. Instead, write keyword-rich titles under 100 characters and descriptions under 500 characters using natural long-tail search phrases like "small kitchen organization ideas for renters."

Can this skill write LinkedIn or Twitter posts?

No, it only covers visual-first platforms where an image or video is the primary content. For text-first posts on LinkedIn, Twitter/X, Threads, or Bluesky, use the post-writer-sms skill instead.

How do I write a YouTube video description for better SEO?

Put the value proposition in the first 150 characters above the fold, keep the title to 60-70 characters with a front-loaded keyword, and add timestamped chapters for videos over three minutes. Use a maximum of three hashtags.
