Allow customizing defaultTools in @commandkit/ai #596
Description
It would be great to have a way to customize or override
defaultTools in @commandkit/ai.
In many cases, not all built-in tools are needed—for example,
createEmbed.
Being able to selectively enable or disable these tools would give developers
more flexibility and help keep implementations cleaner and more intentional.
This would make the library easier to adapt to different use cases without having to work around unused defaults.
