Memory safety violations in Mojo occur when ownership, borrowing, or lifetime rules are broken—causing use-after-move or dangling references. This Skill analyzes ownership transfers using `^`, borrow lifetimes, `mut`/`self` semantics, and non-copyable types to identify and report violations with suggested fixes.

Ownership determines who controls a value's lifetime; borrowing allows temporary access without ownership transfer; lifetimes define how long references remain valid. Mojo enforces these via `owned`, `borrowed`, and `inout` parameters to prevent memory errors and unsafe aliasing.

Run memory safety checks during code reviews, debugging sessions, pre-merge checks, and performance evaluations—especially in performance-critical modules. Early detection prevents use-after-move errors and dangling references from reaching production.

Yes. This Skill automates memory safety checks by detecting ownership and borrowing violations, reducing manual debugging effort. It validates fixes through testing and integrates into code review and pre-merge pipelines.

This Skill catches use-after-move errors, dangling references, mutable aliasing violations, and lifetime mismatches. It detects patterns that violate Mojo's ownership model and guides developers toward robust solutions.

Basic familiarity with Mojo's `owned`, `borrowed`, and `inout` semantics helps, but this Skill provides ownership guidance and explains violations with suggested fixes, making it accessible for developers new to Mojo's memory model.
