What Is Social Media Skills? Installation, 17 Skills, Cost and Permissions
First you extract your own writing voice with voice-builder; then you ask Codex or Claude for a LinkedIn post, a Reels script, a YouTube thumbnail prompt, a carousel or LinkedIn analytics. Social Media Skills is an MIT-licensed open-source collection of 17 independent skills; the skills are text instructions, and the repo has no hooks, MCP server or scripts that run at install. It creates content but does not publish it. Most skills need no extra keys; only the analyze-from-Reel-URL path (reels-scripting) needs Apify and Google AI keys. In Claude Code, installation takes two commands.

What is Social Media Skills for?
A skill is an instruction package that teaches an agent how to work on a topic. This collection has 17 skills; each is a SKILL.md file (two have extra reference files). First you use voice-builder to extract a voice profile from your own writing samples, and then the other skills work in that voice.
| Task | Skill |
|---|---|
| Voice extraction | voice-builder, newsletter-voice |
| Post writing and formatting | post-writer, post-formatter, hook-generator, quote-post, pinned-comment |
| Visuals and thumbnails | graphic-designer, youtube-thumbnail, gemini-infographic, gemini-carousel |
| Video | reels-scripting |
| Research and analysis | niche-research, content-matrix, post-scorer, analytics-dashboard, profile-optimizer |
Who it helps: people who regularly create LinkedIn, Reels or YouTube content and want the agent's writing to sound closer to their own voice.
How do I install Social Media Skills?
The commands are exactly as given in the README.
› /plugin marketplace add charlie947/social-media-skills› /plugin install social-media-skillsFor updates, Claude Code's own plugin update mechanism is used.
Tell Codex: "Use skill-installer to install voice-builder and post-writer from charlie947/social-media-skills, paths skills/voice-builder and skills/post-writer." All 17 folders can be installed the same way. Alternative: clone the repo and copy the skills folders into the project's .agents/skills/ (the README has a loop for this).
Zip the skill folder (with its references folder, if any) and upload it via Customise skills; skills are uploaded one at a time.
Copied or uploaded skills don't update when the source changes (README); the Claude Code plugin route uses its own update mechanism. The documentation has no steps for Cursor and other clients; that doesn't mean they won't work.
How do I use Social Media Skills?
For personal writing, run voice-builder first (or provide your own approved voice files). The README tells you not to use the maintainer's default voice. Then ask in a normal sentence.
Where does Social Media Skills work?
| Claude CodeYes | With two commands. |
|---|---|
| CodexYes | With skill-installer or a copy inside the project. |
| Claude DesktopYes | Upload one at a time as a zip. |
| Cursor, Gemini CLI and othersUnclear | Not stated in the documentation; that doesn't mean they won't work. |
What does Social Media Skills access?
The about-me, voice and newsletter-voice files in the project you choose; the writing samples you provide and your LinkedIn export file. niche-research browses Reddit, X and Google feeds with a browser and search tool.
about-me and voice files in the project, outputs under the outputs folder; post, script and image prompt texts in the chat. reels-scripting writes and runs a Node script.
No deletion step.
The skill files run locally. If you use the Apify or Gemini path, the Reel URL and video go to the respective provider.
!README: saving a draft does not mean publishing it; the skills grant no permission to publish, send messages or change accounts. Don't paste Apify and Google keys into the chat; provide them as environment variables.
The repo has no hooks, MCP server or install script; it only has validation files meant for the maintainer. GitHub Security Advisories is empty; no recorded advisories appear. That doesn't mean it is "safe". One open issue title in the repo looks like a promotional message.
Is Social Media Skills free?
The collection itself is free and MIT licensed; the README lists no fee or plan. The agent tool you use (Claude Code, Codex) has its own separate cost. Third-party routes carry their own costs: reels-scripting's Reel URL analysis needs Apify and Google AI (Gemini) keys, and post-scorer optionally uses Apify. The cost of image generation with Gemini is not stated in the repo.
Common problems
| What happens | What to do |
|---|---|
| Codex skill-installer says "destination already exists" | The installer refuses an existing destination; in a new task, verify that the skill is installed and check its path. |
| The installed skill doesn't change after an update | Copied skills don't update when the source changes: compare the installed folder with the new source, merge while keeping your changes, and reload in a new task. |
How do I uninstall Social Media Skills?
- Claude Code: Remove the plugin from the /plugin menu.
- Codex: Delete the copies under .agents/skills.
- Claude Desktop: Remove the skills you uploaded from the Customise skills screen.
The README doesn't describe an uninstall step; the steps above are the general method.
Frequently asked questions
Which programs does Social Media Skills work in?
