m15-anti-pattern

What it does: This skill helps review computer code written in the Rust programming language and spot bad habits, often called anti-patterns. These are things that technically work but cause problems later, like copying data everywhere instead of sharing it properly, or code that can crash unexpectedly. It gives a table of common bad habits, why they are bad, and a better way to write the same thing. It also includes a checklist and lists of common beginner mistakes to help someone learn better habits over time. When to use it: - Reviewing Rust code to check for shortcuts or sloppy patterns - Someone asks whether a piece of code is written the right way - Someone asks for a more standard or idiomatic way to solve a coding problem - Fixing code that keeps causing crashes, memory waste, or fights against the language's safety rules This is a background reference used automatically during code review, not something a person types as a command.
