+When reviewing code, focus on:
+
+## Language, Libraries & Standards
+
+- Target C++17 and avoid vendor-specific extensions.
+- For Python scripts, follow PEP 8.
+- Prefer standard library or LLVM support libraries instead of reinventing data structures.
+
+## Comments & Documentation
+
+- Each source file should include the standard LLVM file header.
+- Header files must have proper header guards.

It might be useful to add something here to cover "Aim to describe what the code is trying to do and why, not how it does it at a micro level" from our CodingStandards. Basically, I'd like to say "make sure that non-obvious code has comments explaining what it is aiming to do and why"
