Can it help reduce iPhone battery drain?

Yes, it includes energy-specific diagnostics to identify anti-patterns in location tracking, network polling, and background execution that cause high power consumption.

How do I use this if my app just feels 'slow'?

You can invoke the skill with general symptoms, and it will guide you through a decision tree to determine if the issue is related to CPU, memory, or data layer bottlenecks.

How does this skill help with iOS memory leaks?

It provides diagnostic workflows for common leak patterns including timers, observers, closures, and delegates, using specialized sub-skills for both Swift and Objective-C.

Does it support Xcode Instruments?

The skill provides step-by-step guidance on using the Time Profiler, Allocations, and Power Profiler instruments to identify CPU and memory growth issues.

What is the 'energy-ref' sub-skill?

It is a reference library containing complete code examples for power-efficient APIs, including BGContinuedProcessingTask and MetricKit configuration.
