-### Handling Existing PRs for Assigned Issues
-When working on an issue that already has an open PR created by someone else:
-
-1. **Review the existing PR thoroughly** - Examine the proposed changes, implementation approach, and any discussion in comments
-2. **Provide analysis and opinion** - Evaluate whether the existing solution addresses the issue effectively and follows best practices
-3. **Always include a summary** - In your PR description, always include a summary of what you think about any other open PRs for the issue you are working on
-4. **Don't force using existing approach** - Don't try too hard to base your work off the existing PR if you're not confident in that approach
-5. **It's OK to abandon existing PRs** - If you're not confident enough in the existing PR's approach, it's completely acceptable to abandon it and implement a different solution
-6. **Document abandonment reasoning** - If you do abandon an existing PR approach, make sure to add clear notes explaining why you abandoned that approach and what concerns or issues you identified
-7. **Use existing PR as foundation when valid** - If the existing solution is solid and you're confident in the approach, use it as the starting point and foundation for your work
-8. **Identify improvement opportunities** - Look for areas where you can enhance the solution, such as:
-   - Adding comprehensive test coverage
-   - Improving code quality, performance, or maintainability
-   - Enhancing error handling or edge case coverage
-   - Better documentation or code comments
-   - More robust implementation patterns
-9. **Build upon, don't duplicate** - When using an existing approach, extend and improve the existing work rather than creating a competing solution from scratch
