Unnecessary token consumption due to model errors

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

Multiple times in the latest updates to one of my projects, Claude Code duplicated code and resource calls, leaving it quite a mess to untangle.

During troubleshooting, Claude identified that it accidentally created duplicate code and acknowledged that this caused the messy cascade of errors.

There should be a way to recover the tokens from incidents where Claude has made (and can acknowledge) these errors. It's a bad enough user experience when you lose time, but it's a bit of an insult to injury when we are also paying for our lost time with tokens.

What Should Happen?

Recovery of tokens for express cascading error time.

Additional Information

Honestly, not trying to be a complainer. I think it's understandable to be frustrated by the loss of time and (tokens)/money when the errors are coming from the platform, and not due to poor prompting or user error.
