Adversarial pass/fail review gate that enforces the feature-arch skill's React feature-based architecture rules. Use when a diff, branch, PR, or src/ tree must be judged for architecture conformance before merge — feature folder structure, import boundaries,…
Use this skill when reviewing or refactoring existing Rust code that carries an alien mental model — OO/enterprise ceremony from Java/C#, garbage-collected object graphs, exception-style control flow, or imperative loops ported onto the borrow checker. It is…
