Question 1

Are these really free?

Accepted Answer

Yes. Every skill on this page has a price of zero. You need a free Agensi account to download so we can attribute installs and run security scans, but there is no payment, no trial, and no upsell required to unlock the skill itself.

Question 2

Do they work with ChatGPT and Claude?

Accepted Answer

Yes. Free skills use the open SKILL.md format. They work natively in Claude Code and in Codex CLI (the ChatGPT coding agent), and drop into Cursor, GitHub Copilot, Gemini CLI, Windsurf, Aider, Cline and 20+ other agents that read SKILL.md files.

Question 3

What is a skill versus a prompt?

Accepted Answer

A prompt is a single message you type into a chat. A skill is a structured pack: a SKILL.md instruction file plus any supporting scripts, references, or examples, packaged so your agent can auto-load it when a matching task comes up and reuse it across sessions.

Question 4

Do I need an account?

Accepted Answer

Yes, a free account. Sign up with email or Google, then download any free skill. The account lets us attribute installs to real users, run security scans on every download, and give creators feedback on how their work is being used.
