Instagram Caption Writer

Writes an Instagram caption that puts the hook in the first 125 characters, keeps the body skimmable, and lands exactly one CTA.

Marketing & SEOIntermediate★ 768⑂ 163AI score 9/10Last updated: Nov 4, 2026

What it does

Instagram hides everything past ~125 characters behind "more", so this skill makes that first line carry the whole post.

  • Goal-driven hook formulas: saves (number-first result), shares (contrarian truth), comments (relatable cold-open), follows (mini-story confession) — it shortlists 2-3 and lets you pick.
  • Skimmable body + one CTA: short lines, white space, one idea per post. Lazy prompts like "what do you think?" are banned.
  • Humanizer pass: strips AI-tell vocabulary, caps em dashes, breaks stacked triads, kills generic openers and "The result?" reveals.
  • No invented specifics: it will not fabricate a number, date, client name or result you did not actually give it.
  • Approval card and publishing: shows formula, hook character count, full caption, hashtag set and required media, then publishes with your image or Reel via the Publora flow on approval.

Who it's for

  • Solo founders and creators running their own Instagram
  • Social media marketers and brand content managers
  • Writers whose copy is fine but whose hooks are soft
  • Anyone told their captions "sound AI-generated"

Examples

  1. Product launch post: ask for a save-optimized caption → IG1 formula front-loads the result number inside 125 characters, closing with "save this for your next launch".
  2. Reel support caption: the hook lives in the video, so the skill writes the companion caption plus a sized 3-5 hashtag set.
  3. Sharpening a draft: paste an existing caption and get a rewritten hook plus a humanizer audit pass.

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the .codex-marketplace/instagram-skills/skills/ig-caption-writer folder from the GitHub repo sergebulaev/instagram-skills into my ~/.claude/skills/ig-caption-writer/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/sergebulaev/instagram-skills.git /tmp/instagram-skills && mkdir -p ~/.claude/skills && cp -r /tmp/instagram-skills/.codex-marketplace/instagram-skills/skills/* ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/sergebulaev/instagram-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the whole Instagram skill set (don't copy just this one folder — it references shared ../../references/ files): cp -r instagram-skills/.codex-marketplace/instagram-skills/skills/* ~/.claude/skills/ then cp -r instagram-skills/.codex-marketplace/instagram-skills/references ~/.claude/skills/
  5. Restart Claude Code and try: "write me an Instagram caption about ...".
  6. (Optional) For auto-publishing, set up a Publora account and API key. Without a key the skill just returns a copy-paste block and reminds you to attach media.
