What it does

Provides a single CLI (ccpi) to browse, install, and run 471 plugins, 3,069 skills, and 347 agents for Claude Code from an open‑source marketplace.

When to use it

•You need to add a specific capability (e.g., PDF extraction, sentiment analysis) to Claude without writing custom code.
•You want to prototype a Claude‑based workflow quickly by pulling ready‑made agents from a marketplace.
•Your team is building a product that relies on many reusable AI “skills” and you need a central, searchable repository.

Ready-to-paste prompt

Claude, using the installed `text‑summarizer` skill, give me a 3‑sentence summary of this article: https://example.com/long‑blog‑post

Heads up: The CLI only works with Python 3.10 or newer; older versions will raise a `ModuleNotFoundError`. Also, some premium plugins require you to set the environment variable `CCPI_API_KEY` with a key obtained from tonsofskills.com before they can be installed.
