[DOCS] Marketplace documentation lists "pip" as a valid plugin source, but it's not implemented

Documentation Type

Incorrect/outdated documentation

Documentation Location

https://code.claude.com/docs/en/plugin-marketplaces

Section/Topic

Plugin sources

Current Documentation

The docs list the following row:

• Source = pip
• type = object
• Fields = package, version?, registry?
• Notes = Installed via pip

What's Wrong or Missing?

When I tried packaging my claude plugin using pip and then referencing it from my market place specifying source = pip, I got the following error when I tried to install the plugin:

Error: Failed to install: Python package plugins are not yet supported

This incorrect documentation caused me to go down a path of pip packaging and wasted quite a bit of time in developing a pipeline to support publishing plugins as pip modules

Suggested Improvement

Either remove this row if its not supported or say it's "coming" (if it indeed is).

Impact

High - Prevents users from using a feature

Additional Context

I'm using claude code v2.1.78
