What

The artifacts tool now exposes a validationErrorRemedy function that returns a .remedy field alongside its existing validation error message. The related steer-override logic (which can redirect Claude's response after an error) now looks up this same remedy information, falling back to a different message source if none is found.

Why

Providing a specific remedy alongside a validation error should make it easier to correct artifact validation problems, rather than just being told something went wrong.
