Problem Statement

When Claude Code is editing files in a Visual Studio 2026 WSL solution temporary files are not being deleted.

Claude suggested The pattern *.tmp.<pid>.<timestamp> is the Edit tool's atomic write — it writes to the temp file, then renames it to the final destination. If the rename succeeds the temp file vanishes. If it fails (e.g. the file is locked by the linter or VS at that moment), the temp file is left behind.

It does seem that the rename is succeeding as the edited code seems to be correct. This could be a bug.

Proposed Solution

The Edit tool should retry the temporary file delete n times then report if it fails.

Alternative Solutions

I delete the file manually. Sometimes I miss them and they end up in git.

Low - Nice to have

TL;DR

Implement a retry mechanism for deleting temporary files in the Edit tool to handle cases where the initial delete operation fails.

Guidance

  • Investigate the file locking behavior of Visual Studio 2026 and the linter to understand why temporary files might not be deleted even after a successful rename.
  • Consider implementing a retry mechanism with a limited number of attempts (e.g., 3-5) to delete temporary files, as proposed in the issue.
  • Review the Edit tool's atomic write process to ensure it correctly handles temporary file deletion in case of a failed rename.
  • Evaluate the potential impact of manually deleting temporary files on the overall workflow and consider automating this process.

Example

No specific code example can be provided without more context about the Edit tool's implementation.

Notes

The issue's proposed solution focuses on retrying the deletion of temporary files, but it's essential to understand the root cause of the failure to delete these files in the first place. This might involve investigating file system permissions, locks, or other processes interfering with the deletion.

Recommendation

Apply workaround: Implement a retry mechanism for deleting temporary files, as this seems to be a straightforward approach to mitigate the issue, even if it doesn't address the underlying cause of the problem.
