unsafe-checker

What it does: This skill reviews the riskiest kind of Rust code, called unsafe code, which turns off some of the language's normal safety checks. This is sometimes needed for talking to code written in other languages like C, or for very high performance situations. The skill checks that risky code is actually necessary, properly explained with a comment describing why it's safe, and doesn't accidentally cause crashes, memory corruption, or other invisible bugs. When to use it: - Reviewing code that uses unsafe blocks, raw pointers, or connects Rust to another language - Making sure risky code has a clear written explanation of why it's actually safe - Checking for common mistakes like null pointer errors or using memory after it's been freed - Learning what tools are recommended instead of outdated or risky techniques This is a background reviewing tool, used automatically during code review of risky code, not a command typed by a person.
