+Some rules restate familiar principles as checkable boundaries: Grice's maxims shape Communication
+and Output style, with the maxim of quality as the cite-or-mark-unverified rule under Repository

+Occam's razor can favor the smallest diff over the upstream fix. Amend the concrete rule instead.

 After changing the rules or a custom skill, size the evaluation to the change as the
 [evaluation guide](evals/global-rules.md#choosing-the-scope) describes, and record the results in
 the PR.
