Client extensions

Data this package carries for particular clients. The directory lists the clients named and never reads what is addressed to them.

com.github.copilot
com.openai

Fields the format does not define

This package's plugin.json declares these at its top level. The Agent Plugins format gives them no meaning, so a client loads the plugin and ignores them.
