This issue might be a duplicate of existing issues. Please check:

  • #3700: Same error "Added line count did not match for hunk at line 76" - triggered by /undo after tool_use/tool_result error
  • #3818: Same error "Added line count did not match for hunk at line 14" - similar diff parsing issue
  • #3812: Same error "Added line count did not match for hunk at line 43" - same diff parsing failure (closed)

All appear to be the same underlying issue with diff/patch parsing in the opentui implementation when using undo functionality after multiple modifications.

Feel free to ignore if none of these address your specific case.
