What kind of background issues can this skill diagnose?

It targets common symptoms like tasks never running, early termination, URLSession delegate failures, production-only bugs, and crashes on background launch.

Does it provide code for testing background tasks locally?

Yes, it provides specific LLDB commands to simulate task execution and expiration directly within the debugger, bypassing system scheduling delays.

Can it help with 'works in dev, not prod' issues?

Absolutely. It analyzes the 7 system scheduling factors—like Low Power Mode and app usage patterns—that often prevent background execution in real-world scenarios.

What are the time-cost analyses included in the skill?

It provides estimates for various troubleshooting steps (e.g., checking Info.plist vs. adding logging), helping you choose the fastest path to a resolution.

Mobile Development

Troubleshoots complex iOS and xOS background task issues using symptom-based decision trees and diagnostic workflows.

关于

Axiom Background Processing Diagnostics is a specialized skill designed to help developers solve the most common and frustrating issues with background execution on Apple platforms. It provides structured logic for diagnosing why tasks fail to run, terminate early, or behave differently in production than in development. By integrating expert knowledge of BGTaskScheduler, system constraints, and debugging techniques, the skill empowers Claude to provide actionable fixes, LLDB commands for simulation, and time-cost analysis to optimize the debugging process.
