I have a few qualms about this standard:

1. For an experienced Claude Code user, you can already build such an agent persona quite trivially by using the /agents settings.

2. It doesn't actually replace agents. Most people I know use pre-defined agents for some tasks, but they still want the ability to create ad-hoc agents for specific needs. Your standard, by requiring them to write markdown files does not solve this ad-hoc issue.

3. It does not seem very "viral" or income-generating. I know this is premature at this point, but without charging users for the standard, is it reasonable to expect to make money off of this?
