FAQ

What are Agent Skills?

Agent Skills are folders with a SKILL.md file: a YAML name and description, then instructions and optional scripts. AI agents like Claude Code load a skill automatically when your request matches its description, so they follow a proven workflow instead of improvising.

Which AI agents do these skills work with?

Claude Code natively, through its plugin marketplace. Cursor, Codex, Cline, Windsurf, GitHub Copilot, Gemini CLI, OpenCode and 75+ other agents work through npx skills. Any agent can also use a SKILL.md pasted into its rules file.

How do I install all skills in Claude Code?

Run /plugin install all-skills --marketplace milad-ahmd/agent-skills inside Claude Code, or install a role pack such as creator-pack or startup-cto-pack.

Is there an AI agent skill for Instagram, TikTok and YouTube?

Yes: instagram-growth-manager, tiktok-viral-creator, youtube-seo-optimizer and youtube-script-writer. social-media-manager coordinates them along with the LinkedIn, X, Facebook, Pinterest, Threads, Reddit, Telegram, WhatsApp and Google Business Profile agents.

Are the skills free?

Yes. All 51 skills are open source under the MIT license. They are plain Markdown with optional Python scripts that use only the standard library, and they need no paid API.
