Activates when you're working with unsafe Rust blocks, FFI bindings, or raw pointers. Displays quick reference tables for safety requirements (dereferencing, transmute, extern calls), common errors like null pointer derefs and use after free, and deprecated patterns you should avoid (like mem::uninitialized). Also covers FFI tooling like bindgen and cbindgen. The real value is having those SAFETY comment examples and soundness checklists right there when you need them, since unsafe code review is all about documentation and understanding invariants. Best paired with actual unsafe Rust knowledge, this is a checklist not a tutorial.
