SKILL.md

Unsafe Rust code review and FFI soundness checker for identifying memory safety violations.

Triggers on 30+ unsafe patterns including raw pointers, transmute, FFI declarations, uninitialized memory, and missing SAFETY documentation

Provides reference tables for valid unsafe use cases (FFI, low-level abstractions, performance bottlenecks) and common errors with fixes

Covers FFI tooling recommendations (bindgen, cbindgen, PyO3, napi-rs) and deprecated patterns with modern alternatives

Requires SAFETY comments on all unsafe blocks and unsafe function signatures to document why code is sound
