+          Please analyze and fix the GitHub issue $ARGUMENTS.
+
+          Follow these steps:
+          1. Use `gh issue view` to get the issue details
+          2. Understand the problem described in the issue. If necessary, follow links to other mentioned issues to understand context
+          3. Search the codebase for relevant files
+          4. Implement the necessary changes to fix the issue
+          5. Write and run tests to verify the fix
+          6. Ensure code passes linting and type checking
+          7. Create a descriptive commit message
+          8. Push and create a PR
+
+          Remember to use the GitHub CLI (`gh`) for all GitHub-related tasks.
