What is it?
Tons of Skills is a marketplace for agent skills and plugins. Its canonical skill layer is designed to be independent of any particular agent harness, and Claude Code is the harness the project currently verifies as native. Other harnesses are treated as candidates until their integration is verified.
The catalog is organized into categories such as AI and machine learning, DevOps and infrastructure, databases, security, testing, and productivity, with a large set of SaaS skill packs. Plugins can be installed with a Claude Code marketplace command or with the ccpi CLI, which is published as an npm package.
The repository also distinguishes between first-party canonical skills, generated adapters, first-party packages, and upstream mirrors. Upstream plugins are mirrored with their author, license, and pinned commit recorded, and the contributor's repository remains the source of truth.

- 01Harness-free canonical skill layer, with Claude Code as the currently verified native harness.
- 02Install the whole marketplace with one Claude Code command, or install individual packs via the ccpi CLI.
