Plugin type-generation help now points authors to a new claude plugin validate command

What

The help text shown by the plugin type-generation tooling now tells plugin authors about claude plugin validate <dir>, a command that reads a plugin the same way Claude Code's engine would and reports what it hooks into, what it calls, and what it would refuse to do.

Why

This gives plugin authors a way to check how their plugin will actually be interpreted before shipping it, catching issues earlier.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed since Anthropic's documentation has since written up claude plugin validate, on Plugins reference. If you break any of these rules, the plugin fails to load. Run `claude plugin validate` to see which field breaks which rule. plugins-reference see the edit
