Does this skill just suggest adding .clone() to fix errors?

No, it encourages deeper design thinking to determine if data should be owned, shared, or restructured, helping you avoid the 'clone everywhere' anti-pattern.

How do I trigger this skill within Claude Code?

The skill triggers automatically when Claude encounters keywords like 'ownership', 'borrow', 'lifetime', or specific Rust error codes in your code or terminal output.

What common Rust errors does this skill help resolve?

It specifically targets ownership-related errors like E0382 (moved value), E0597 (borrowed value doesn't live long enough), and E0506 (cannot assign while borrowed).

Can it help with multi-threaded Rust development?

Yes, it provides guidance on using Arc and Mutex versus Rc and RefCell based on whether your data needs to be shared across threads or remains in a single-threaded context.

Guides developers through resolving complex Rust ownership, borrowing, and lifetime errors using idiomatic design patterns.

关于

The m01-ownership skill transforms Claude into a specialized Rust consultant focused on the language's core memory safety mechanics. It provides a structured thinking framework for handling notorious borrow checker errors like E0382 and E0597, moving beyond superficial fixes to address underlying design flaws. Whether you are dealing with multi-threaded data sharing, complex reference hierarchies, or unnecessary allocations, this skill helps you decide between move semantics, smart pointers like Arc or Rc, and proper lifetime annotations to ensure safe and efficient code.
