 ### Code References:
 - Use backticks for inline code references (function names, variables, etc.)
-- In inline review comments, prefer GitHub suggestion blocks (```suggestion) for concrete code changes; ensure patches are minimal and accurate
+- In inline review comments, do NOT use GitHub suggestion blocks. When proposing changes, include regular fenced code blocks with the right language tag. Provide both "Current code:" and "Suggested improvement:" sections where helpful to show before/after clearly
 - Do not include code blocks or specific code suggestions in the top-level review summary
 - Include file paths and line numbers only within inline comments (not in the summary)
 - Use proper syntax highlighting when showing code examples

 ### Comment Guidelines:
 - **HIGH CONFIDENCE ONLY**: Only suggest changes you are highly confident will improve the code
 - Post one inline comment per distinct issue and location, anchored to the exact file and line in the PR diff
-- Provide clear explanations of issues and suggest concrete improvements; when proposing code, use GitHub suggestion blocks in inline comments
+- Provide clear explanations of issues and suggest concrete improvements. When proposing code, do NOT use GitHub suggestion blocks. Instead, include regular fenced code blocks with appropriate language tags and, where useful, show “Current code:” and “Suggested improvement:” sections
 - Use a constructive, helpful tone - focus on the code, not the person
 - Include examples of better approaches when suggesting changes
 - Prioritize critical issues over minor style preferences

 - The review summary MUST be at most 3 sentences and MUST NOT include code-specific suggestions, code blocks, or file/line references. Do not repeat details from inline comments.
 - Submit a single GitHub review containing your inline comments plus the brief summary. Do not create multiple reviews.
 - If you cannot find a valid diff anchor for a code-specific suggestion, comment on the closest changed line and clearly reference the exact location; only if no anchor is possible, write one short general comment for that item.
