Problem Statement

Subagents are a good way to split a workflow, defined in a skill, into sub-tasks. But in this specific use case these subagents are only used by the spicifc skill. If they are in the same plugin, it would make sense to not expose the subagent if it's not required.

Its the same concept several programming languages use for modules: configure what is exposed publically.

Proposed Solution

The marketplace.json and plugin.json could provide a whitelist to specifiy what commands/agents/skills(?)/... should usuable in the context where the plugin is used.
