Does this skill support the Zig test allocator?

Yes, it specifically checks for proper cleanup when using std.testing.allocator to ensure your tests pass without leak reports or memory-related failures.

Does it help with Zig error handling cleanup?

Absolutely, it suggests using errdefer to ensure resources are freed when a function returns an error early, preventing leaks on failing code paths.

Can it detect leaks in complex loops?

Yes, it identifies patterns where allocations occur inside iterations without corresponding deallocations or the use of an arena for per-iteration cleanup.

Is it compatible with custom Zig allocators?

Yes, it looks for general allocation and deallocation patterns (alloc/free, create/destroy, init/deinit) regardless of the specific allocator implementation used.

Security & Testing

Identifies and fixes potential memory leaks in Zig code by analyzing allocation patterns and resource cleanup logic.

The Zig Memory Leak Detector is a specialized skill designed to help developers navigate Zig's manual memory management with confidence. It analyzes code for common pitfalls such as missing defer statements, improper test cleanup, and unhandled error paths that lead to resource leaks. By enforcing best practices like allocation/deallocation pairing, proper struct deinit implementations, and effective use of ArenaAllocators, this skill ensures that Zig applications remain performant and memory-safe. It is particularly useful during code reviews, debugging sessions, or when implementing complex data structures that require precise lifecycle management.
