Rust unsafe

Purpose

Guide agents through writing, reviewing, and reasoning about unsafe Rust: what operations require unsafe, how to write safe abstractions, audit patterns, common pitfalls, and when to reach for unsafe.

Triggers

• "When do I need to use unsafe in Rust?"
• "How do I write a safe abstraction over unsafe code?"
• "How do I audit an unsafe block?"
• "What are the rules for raw pointers in Rust?"
• "What does transmute do and when is it safe?"
• "How do I implement UnsafeCell correctly?"

Workflow
