# Guardrails This skill is a reference library, not a workflow. Other skills read it at the point where they need to write, change, or review code; it has no standalone "run" behavior of its own. ## What's Here | File | Covers | Read When | |------|--------|-----------| | `core.md` | Security baseline, code-review dimensions and severity levels, unit-testing principles, and anti-mistake rules for AI coding agents | Always — every coding or review task | | `java.md` | Java exception handling and concurrency anti-patterns, JVM testing pitfalls | Project is Java/Kotlin/JVM | | `go.md` | Go error handling and testing pitfalls | Project is Go | | `cpp.md` | C++ memory safety, concurrency, error handling, and testing pitfalls | Project is C++ | | `web.md` | Frontend/Node security and quality pitfalls | Project is TypeScript/JavaScript/web | | `android.md` | Android-specific safety and quality pitfalls | Project is Android/Kotlin | | `ios.md` | iOS-specific safety and quality pitfalls | Project is iOS/Swift | | `flutter.md` | Flutter/Dart-specific safety and quality pitfalls | Project is Flutter | ## How to Use This 1. Detect the project's primary language/stack (build files, file extensions, existing code) or ask if it's ambiguous. 2. Read `core.md` in full — it applies regardless of stack. 3. Read the one or two language files that match the project's stack. Skip the rest. 4. Apply the checklists while writing code, and re-check against them during review, before claiming a t
