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

  • #2720: Reports the exact same 'tool_use blocks found without corresponding tool_result blocks' error that triggers this diff parsing issue
  • #2214: Another instance of the tool_use/tool_result mismatch error
  • #1662: Similar tool_use/tool_result validation error
  • #2379: Specifically mentions /undo being broken with diff-related errors

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

Looks like I have a similar issue:

I was writing a prompt using OpenCode Zen Big Pickle. I canceled the prompt using esc-esc then used /undo when this occurred. Trying to re-open the session results in this issue showing up:

@thdxr commented on GitHub (Nov 3, 2025):

Fixed by adding try-catch blocks around parsePatch calls to handle malformed diffs gracefully. Prevents TUI crashes when undoing after tool_use/tool_result errors or cancelled prompts. ✅

Delete Branch "%!s()"

Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
