Caption Writer Sms

You're looking at a caption for a photo or video you're about to post on Instagram, TikTok, Pinterest, Facebook, or YouTube. This skill writes the text that goes under the visual, not the visual itself. It knows the platform differences: Instagram truncates at 125 characters so the hook better land fast, TikTok captions are now searchable long-form, Pinterest needs SEO-friendly descriptions, Facebook still likes conversational storytelling. It checks for a context file first to match your voice, then asks what platform, what the visual shows, and what action you want people to take. The output follows a three-part structure: hook, payoff, CTA. Useful if you're staring at a great piece of content and have no idea what words should go with it.

Caption Writer

When to Use

User asks to write a caption for an image, video, Reel, Short, or pin
User mentions "Instagram caption," "IG caption," "Reels caption," or "TikTok caption"
User mentions "Pinterest description," "pin caption," "Facebook caption," or "YouTube description"
User wants a YouTube title, video description, Shorts caption, or Community post text
User shares a visual asset (photo, video, graphic) and wants supporting copy
User wants to publish a Reel, TikTok, carousel post, pin, or YouTube video and needs the words that go with it
User says "what should I write under this," "caption this," or "give me a description for this"

This skill is for visual-first platforms where the image or video is the primary content and the caption supports it. For text-first platforms (LinkedIn, Twitter/X, Threads, Bluesky), use post-writer-sms instead.
