+      instructions: |
+        For documentation changes, focus on:
+        - Accuracy: Verify code examples compile and run correctly
+        - Completeness: Check if API changes (parameters, return values, errors) are documented
+        - Clarity: Flag confusing explanations, missing prerequisites, or unclear examples
+        - Consistency: Version numbers, parameter types, and terminology match code
+        - Examples: Suggest adding examples for complex features or new APIs
+        - Missing docs: If PR changes public APIs without updating docs, flag as HIGH priority
+
+        When code changes affect docs:
+        - Suggest specific doc files that need updates (e.g., docs/cuopt/api.rst)
+        - Identify outdated information contradicting the code changes
+        - Recommend documenting performance characteristics, GPU requirements, or numerical tolerances

+      instructions: |
+        For public header files (C++ API):
+        - Check if new public functions/classes have documentation comments (Doxygen format)
+        - Flag API changes that may need corresponding docs/ updates
+        - Verify parameter descriptions match actual types/behavior
+        - Suggest documenting thread-safety, GPU requirements, and numerical behavior
+        - For breaking changes, recommend updating docs and migration guides
