Can I use it for automated performance testing?

Yes, it includes specialized support for the xctrace CLI and headless profiling, which are essential for CI/CD performance regression testing.

Does it support watchOS and tvOS applications?

Yes, the axiom-ios-performance skill is designed for the entire modern xOS ecosystem, covering performance patterns applicable across all Apple platforms.

How does this skill help with memory leaks?

It provides specific diagnostic paths for Swift closures and Objective-C block patterns, helping you identify common retain cycles and verifying why deinit is not being called.

What should I do if my app is draining the user's battery?

The skill offers an energy diagnostic tree to identify thermal issues, high energy usage in background tasks, and inefficient network or location API usage.
