KSCrash

Catch and diagnose iOS and macOS app crashes automatically

Captures crashes, hangs, exceptions, and OS-level terminations in Apple platform apps and generates complete crash reports. Reviews crash handler code for async-signal-safety violations by verifying system calls against Apple's open-source implementations. Eliminates manual crash log analysis and unsafe signal handler bugs that corrupt crash reports.

Frequently Asked Questions

FAQPage Schema
How to install KSCrash?▼

Run `npx skills add kstenerud/KSCrash --all -g -y` in your terminal to install all skills in this suite globally.

What is async-signal-safety in crash reporting?▼

Crash handlers run inside signal handlers where most system functions are unsafe to call. This skill reviews your code changes and flags any locks, allocations, or Objective-C calls reachable from the signal path.

How does the signal safety review verify system calls?▼

Instead of guessing, it reads the actual function implementations in Apple's open-source repositories on GitHub and cites the exact file and line where a lock or allocation occurs.

Can I review a pull request for crash handler bugs?▼

Yes. Pass a PR number, branch, or file path and the skill traces every call chain from the signal handler entry point to find unsafe calls, grouped by root cause.

Does this work with Claude Code?▼

Yes. The skill follows the universal SKILL.md standard and runs directly in Claude Code and other compatible AI coding agents.
