An agent skill is a folder your coding agent reads: a SKILL.md holding the instructions, plus any reference files, templates or examples it needs. Install one and your agent picks up a capability without you pasting anything.
Browsing the catalogue
The public skills hub is open to everyone, no account required. Signed in, Skills in the sidebar adds the full browse chrome:
- Search as you type, or narrow with the category chips.
- Filter by Free or Premium access.
- Sort by newest, most installed, or top rated.
Every card opens that skill's detail page.
Read it before you install
The detail page is a file browser: the package tree on the left, a viewer on the right with SKILL.md already open. Click any file to read it. The tree is always visible (every path and every file size), so you can see what a package contains before you decide.
- Free skills open completely for any signed-in member.
- Premium skills follow the same paid rule as premium prompts: reading another creator's premium contents needs an Explorer plan or higher. Press Reveal contents and that skill stays unlocked for good.
Installing it
The sidebar hands you a one-liner:
npx promptdock@latest install handle/skill-slugRun it in your project. On first use it walks you through signing in from your browser, then asks which agent to install into (Claude Code, with experimental targets for other agents) and whether to install for this project or for your whole machine. Every file is checksum-verified before anything is written, and an install is all-or-nothing.
No terminal handy? Download .zip on the same panel gives you the identical package, and counts as an install for the creator just like the command does.
The rest of the command set (update, uninstall, list, CI usage and every error code) is in the CLI docs.
