TL;DR

The issue might be resolved by ensuring the file path to the session is correctly formatted and exists in the expected location.

Guidance

• Verify that the file woolly-imagining-minsky.md exists in the directory C:\\Users\\iangr\\.claude\\plans\\ and that the path is correctly formatted.
• Check the current working directory C:\\Users\\iangr\\src\\sandbox-runtime to ensure it's the expected location for the session files.
• Compare the expected file path C:\\Users\\iangr\\.claude\\plans\\woolly-imagining-minsky.md with the actual file path provided in the error message to identify any discrepancies.
• Ensure that the file path does not contain any trailing slashes or incorrect casing.

Example

No code snippet is provided as it's not clearly supported by the issue.

Notes

The issue seems to be related to file path inconsistencies, but without more information about the Ultraplan configuration and session management, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Verify and correct the file paths to ensure they match the expected locations and formatting, as this seems to be the most likely cause of the issue.
