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

   • bug: parallel edit tool calls on same file will error out #2882: Describes parallel edit tool calls on same file causing errors, which appears to be the same race condition where multiple rapid changes to a file interfere with each other
   • Potential race condition for displaying streamed messages in the TUI as one single message #196: Mentions a race condition with streamed operations, potentially related to the same timing issues with sequential operations

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

   Found workaround: set permission "write": true. OpenCode rejects writes out of the working directory, and has functionality to undo the last edit. So I think this permission must be safe for most cases

   I think write tool is being enabled by default. Also, to reproduce this error, the file do not have to be outside of cwd.
