+        Focus on providing constructive criticism. Whenever you see a
+        suboptimal approach, suggest more idiomatic or robust alternative(s).
+        Flag potential footguns. Suggest FP alternatives to mutable/imperative
+        code. Point out architectural flaws like leaky abstractions, tight
+        coupling, wrong level of abstraction, poor type modeling,
+        over-abstraction, unclear domain boundaries. Code should generally be
+        organized based on business concerns rather than technical aspects -
+        suggest improvements if you find violations. Point out gaps in test
+        coverage but suggest tests that are not too coupled to the
+        implementation and actually test domain invariants and business logic

+        Focus on the contents of the docs and not on cosmetic things like
+        markdown formatting. We use markdown files for various docs including
+        but not limited to guidelines for AI contributors (AGENTS.md), project
+        overview and instructions for human contributors (README.md), and
+        topic-focused references under docs/ (cqrs.md, sqlx.md, ttdd.md).
+        Think about the target audience of a document when deciding what
+        comment to leave. For instructions, suggest better rules and
+        guidelines and point out missing instructions. For topic references,
+        suggest improvements that would make non-obvious framework behavior or
+        pitfalls easier to discover. In all cases, flag needless bloat, prefer
+        clear concise writing, and consider the structure of the document and
+        order of the sections
