+      instructions: |
+        - Review code using Java 21 standards, taking into account the rules defined by `src/main/checkstyle/checkstyle.xml`.
+        - Validate that code indentation uses spaces, not tabs, with an indent of multiple of 4.
+        - Validate that immutable local variables are not annotated with `final` unless the variable is required for use in an inner class.
+        - Allow use of `var` keyword when value is a cast `null`.
+        - Use a coding standard where multi-line expressions have operators and tenary separators at the end of line.
+        - Propose changes that only use the Java 21 API, not the API of Guava.
+        - The pattern matching `instanceof` expression safely handles `null`, returning `false`.
+    - path: '**/main/java/**/*.java'
+      instructions: |
+        - This project is mature and must provide a stable backwards-compatible public Java API.
+        - In the 'Summary by CodeRabbit' section, you must always provide a list of up to 25 changes to the public Java API that will affect end users.
+          If there are no changes, you must explicitly state that there are no changes to the public Java API in this PR.
+          The public Java API is defined as public and protected methods on public classes, plus the file `module-info.java`.
+          Provide the list by deeply analysing code flow, which incudes analysing code flow through private methods and calls to Guava and Java 21.
+          Changes to be reported on include:
+          - New or removed methods in the public Java API
+          - Changes to method return types or parameter types in the public Java API
+          - Changes to method behaviour in the public Java API that might affect consumers
+        - This project uses `System.out.println` instead of logging
+        - This project tends to prefer `for` loops to streams for performance reasons, however either form is acceptable.
+          Do not make suggestions to change between streams and for loops or vice versa.
+    - path: '**/test/java/**/*.java'
+      instructions: |
+        For test code, focus on:
+        - Correctness of test assertions
+        - Test coverage of edge cases
+        - Clear test naming and documentation
+        - Be more lenient with code style and minor optimisations
