claude-code - 💡(How to fix) Fix [BUG] Cowork Save Skill fails with INVALID_PATH when Mac username contains a space [1 participants]

LocalFileAccessError: [INVALID_PATH] Failed to resolve path: /Users/davesfingerprint macbook/Library/Application Support/Claude/local-agent-mode-sessions/.../outputs/smart-sequence.skill

TL;DR

The issue can be fixed by properly escaping or quoting spaces in the Mac username when constructing file paths in Cowork.

Guidance

• Verify that the error occurs only when the Mac username contains a space by testing with a username without spaces.
• Check the Cowork code for the specific line where the file path is constructed and ensure that it handles spaces correctly, possibly by using a library function to create a valid path.
• Consider using a temporary workaround, such as creating a symlink or alias for the user's directory with a space-free name, to allow saving skills while a permanent fix is developed.
• Review previous versions of the code to identify when the regression occurred and what changes may have introduced the bug.

Example

No specific code example can be provided without access to the Cowork codebase, but the fix would involve modifying the file path construction to handle spaces, possibly using a function like path.join() or ensuring that the path is properly quoted.

Notes

The exact fix will depend on the specifics of the Cowork code and how it constructs file paths. This issue may not be limited to macOS, as other operating systems may also have similar issues with spaces in usernames.

Recommendation

Apply workaround: Until the root cause is identified and fixed, using a temporary workaround such as a symlink or alias for the user's directory can allow users with spaces in their Mac usernames to save skills.
