1. Organize and summarize the concerns raised by reviewers.
2. Group comments by file and theme (e.g., logic error, naming, security, performance).
3. Preserve all metadata such as who made the comment, the code snippet context, and the line number.
4. Suggest possible resolutions for each unresolved comment.
5. Highlight critical or blocking issues separately at the top.

- **Exact comment text**
- **Highlighted code block (if available)**
