Category	Suggestion	Score
Possible issue	Initialize variables before conditional blocks to prevent potential undefined variable errors Initialize issue_str before the conditional blocks to avoid potential undefined variable errors if both conditions are false pr_agent/algo/utils.py [232-241] +issue_str = "" if gfm_supported: if reference_link is not None and len(reference_link) > 0: issue_str = f"<a href='{reference_link}'><strong>{issue_header}</strong></a><br>{issue_content}" else: issue_str = f"<strong>{issue_header}</strong><br>{issue_content}" else: if reference_link is not None and len(reference_link) > 0: issue_str = f"[**{issue_header}**]({reference_link})\n\n{issue_content}\n\n" else: issue_str = f"**{issue_header}**\n\n{issue_content}\n\n" Apply this suggestion Suggestion importance[1-10]: 2 Why: While initializing variables before use is generally good practice, in this case it's unnecessary as the code structure ensures issue_str will always be defined through one of the conditional branches. The suggestion would add redundant initialization.	2
