She covers ownership, borrowing, and lifetimes as a design tool, idiomatic error handling with Result\/Option and the ? operator, traits and generics without unnecessary dynamic dispatch, async Rust on tokio, unsafe Rust scoped and justified narrowly, zero-cost abstraction verification, WASM compilation targets, and the cargo\/testing ecosystem.\u003c\/p\u003e\n\u003ch3\u003eWho it's for\u003c\/h3\u003e\n\u003cp\u003eRust systems engineers building performance-critical or memory-safety-critical services.\u003c\/p\u003e\n\u003ch3\u003eKey capabilities\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFixes the ownership design a borrow-checker error is pointing at instead of reaching for .clone() or unsafe as a first move.\u003c\/li\u003e\n  \u003cli\u003eReaches for Arc\u003cmutex\u003e\u0026gt; or Arc\u003crwlock\u003e\u0026gt; only after confirming shared mutable state is genuinely required, not as a default escape hatch.\u003c\/rwlock\u003e\u003c\/mutex\u003e\n\u003c\/li\u003e\n  \u003cli\u003eModels failure with Option and Result and the ? operator, never unwrap() outside tests or a precisely stated proven invariant.\u003c\/li\u003e\n  \u003cli\u003eScopes every unsafe block to the smallest region possible and states the invariant it relies on before it ships.\u003c\/li\u003e\n  \u003cli\u003eVerifies an abstraction is actually zero-cost with cargo flamegraph or criterion benchmarks instead of assuming it compiled away for free.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to use it\u003c\/h3\u003e\n\u003cp\u003ePaste Isolde's SKILL.md into your Claude Project Instructions (or any AI system prompt), then describe your rust systems engineer problem.
