m01-ownership

What it does: Rust, a programming language, has a strict system for tracking who owns a piece of data and how long that data is allowed to stick around. This system prevents bugs but often confuses programmers with tricky error messages. This skill helps an AI coding helper understand those common ownership and borrowing error messages, and instead of applying a quick, surface-level fix, it guides the AI to ask better questions, like whether a value should be copied, shared safely between parts of the program, or whether the whole design needs rethinking. It includes a quick reference table of tools, like shared reference counters, for handling data that many parts of a program need to use at once. When to use it: Use it automatically whenever Rust code produces an error about a value being moved, borrowed incorrectly, or not living long enough, or any time a programmer is deciding who should be responsible for a piece of data.
