Draft an Instagram caption with the hook in the first 125 characters, a skimmable body, and one clear CTA, using a 2026 hook formula chosen by goal (saves, shares, comments, follows). Runs the humanizer pass and, on approval, publishes with the image or video you supply via the Publora media flow. Use to caption a single image or a Reel. Not for slide-by-slide carousels (use ig-carousel-planner) or auditing a draft (use ig-humanizer --mode audit).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Instagram Caption Writer Write a caption that earns the tap and the save. Instagram hides everything after ~125 characters behind "more", so the hook does the entire job in the first line. This skill front-loads that hook, keeps the body skimmable, and lands one clear call to action. ## When to use - User says "write me an Instagram caption about X" - User has a single image or a Reel and needs the caption around it - User wants a sharper hook for a draft they already have - User wants a caption that auto-publishes with their media on approval ## Formulas this skill uses (caption-first shapes) | Code | Formula | Primary goal | Best for | |---|---|---|---| | IG1 | Number-First Result | saves | one odd-precision result + a "steal this" promise | | IG2 | Contrarian Truth | shares | a sharp, defensible against-the-grain claim | | IG3 | Relatable Cold-Open | comments | a specific shared moment, no setup | | IG4 | Mini-Story Confession | comments, follows | a real first-person story with a cost | Full skeletons in `../../references/hook-formulas.md`. For carousels (IG5-IG8) use `ig-carousel-planner`; for Reels (IG9-IG10) the hook lives in the video, and this …

How to install
mdr add sergebulaev/instagram-skills/ig-caption-writer@sha256:d8d2f5732d2ab955The line at the top of this page pins the label git:20261003.efb31ed, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
