close output file: %w

Error message

close output file: %w

What it means

Deferred cleanup in executeReviewContext: after the review finishes, closing the output file opened by resolveOutputWriter (used for --output redirection) failed. The close error is joined with the function's result via errors.Join so it does not mask the review's own exit status, but data may not have been fully flushed to the output file.

Solutions

1. Check permissions and disk space for the output file location
2. If writing to a pipe or special file, ensure the consumer still exists
3. Note the review itself may have succeeded — this error only concerns closing the output writer; check whether the output file is complete
