Performs comprehensive Rust security review for safe/unsafe boundary issues, memory safety in unsafe blocks, concurrency hazards, panic-induced DoS, FFI safety, and async runtime mistakes. Use when auditing Rust crates, services, or libraries — particularly those with `unsafe`, FFI, or concurrent code.

Guide agents to use `package:ffigen` to automatically generate FFI bindings instead of writing them manually. Use this skill when a task involves writing new FFI bindings, extending C/Objective-C/Swift integrations, or replacing hand-crafted `dart:ffi` setups.

Builds Flutter plugins that provide native interop for other apps to use. Use when creating reusable packages that bridge Flutter with platform-specific functionality.

Interoperates with native platform APIs on Android, iOS, and the web. Use when accessing device-specific features not available in Dart or calling existing native code.
