 - Method size — Keep methods focused and small. Extract helper methods to improve readability and testability.
 - Cognitive complexity — Reduce nested conditionals and heavy branching by extracting methods, using polymorphism, or applying the Strategy pattern.
 - Duplicated literals — Extract repeated strings and numbers into named constants or enums to reduce errors and ease changes.
-- Dead code — Remove unused variables and assignments. They confuse readers and can hide bugs.

 ## Build and Verification
 
 - After adding or modifying code, verify the project continues to build successfully.
-- If the project uses Maven, run `mvn clean install`.
+- Suggest new unit tests for added functionality to maintain high coverage.
+- If the project uses Maven, run `mvn clean verify`.
 - If the project uses Gradle, run `./gradlew build` (or `gradlew.bat build` on Windows).
 - Ensure all tests pass as part of the build.
