codexSession: create image dir: %w

Error message

codexSession: create image dir: %w

What it means

Wraps a failed os.MkdirAll of <workDir>/.cc-connect/images in codexSession.stageImages. It fires when the working directory (or the .cc-connect subdir) is not writable, so image attachments cannot be staged for the prompt.

Solutions

1. Fix write permissions on the project workDir
2. Ensure .cc-connect is not blocked by an existing file of that name
3. Retry the message with the image after repair
