1. If no PR number is provided in the args, use Bash(`gh pr list`) to show open PRs
2. If a PR number is provided, use Bash(`gh pr view $ARGUMENTS`) to get PR details

4. Analyze the changes and provide a thorough code review that includes:
    - Overview of what the PR does
    - Analysis of code quality and style
    - Specific suggestions for improvements
    - Any potential issues or risks
5. Providing code review comments with suggestions and required changes only:

Keep your review concise but thorough. Focus on:
