A free GitHub toolkit gives Claude and Codex 17 skills for content creation

Charlie Hills published Social Media Skills, a free set of 17 standalone instruction files that plug into Claude or Codex rather than functioning as a hosted app, on GitHub. The whole thing is MIT-licensed markdown, no subscription, no account beyond whatever third-party APIs individual skills need, and the repository has already picked up more than 4,100 stars since launching earlier this year. Two foundational skills, voice-builder and newsletter-voice, study a person’s existing writing and build a profile the other 15 skills read from, which is what lets the system produce drafts that sound like a specific person rather than generic AI copy.

The actual toolset leans hard toward LinkedIn rather than social media broadly. Niche-research pulls up to 20 dated stories from the past week to surface topics worth covering, and content-matrix pairs three to five content pillars with eight formats to generate two to three dozen post ideas at once, standing in for a content calendar without actually scheduling anything. Hook-generator produces six different angles for an opening line, post-formatter turns a topic into a finished draft using established copywriting structures like AIDA and PAS, and post-scorer checks a new draft against a person’s own posting history before it goes out. Reels-scripting and youtube-thumbnail cover the two pieces of video content included, analyzing a reference Reel to draft a script in the user’s voice and turning a video title into an image-generation prompt for a thumbnail concept.

Where this differs from the typical AI content tool is in how it treats measurement. Analytics-dashboard takes a raw LinkedIn analytics export and turns it into an interactive dashboard with five specific recommendations, closer to what a paid analytics product would offer than what free prompt libraries usually include. The rest of the kit covers smaller jobs, profile rewrites, carousel and infographic layouts, pinned comments, quote posts, the kind of formatting work that normally eats time without needing real judgment. None of it requires installing all 17 skills at once; a person can pull just the handful that fit their workflow into Claude or Codex and skip the rest, which is closer to how open-source tooling is supposed to work than how most “AI for creators” products are packaged and sold.
