SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the common and difficult-to-debug concurrency defects in Objective-C and Objective-C++ code, such as data races, deadlocks, and unsafe memory access, which often lead to intermittent crashes and flaky behavior.

Core Features & Use Cases

  • Static Analysis: Scans Objective-C/C++ code for common concurrency anti-patterns.
  • Prioritization: Identifies high-risk areas like deadlocks and data races.
  • Use Case: When a developer reports intermittent crashes related to background operations or UI updates, this skill can quickly pinpoint potential thread-safety issues.

Quick Start

Run the concurrency scan on the current directory and output results to /tmp/objc-concurrency-audit.

Frequently Asked Questions about objc-concurrency-bug-audit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find data races and deadlocks in an Objective-C codebase?▼

To find data races and deadlocks in Objective-C, you can run a static analysis scan that examines threading patterns, synchronization mechanisms, and queue misuse to identify potential thread-safety bugs.

What causes intermittent crashes during background operations or UI updates in Objective-C?▼

Intermittent crashes during background operations or UI updates in Objective-C are typically caused by concurrency defects such as unsafe shared mutable state, data races, and deadlocks.

How do I audit Objective-C++ code for unsafe shared mutable state and thread-safety bugs?▼

You can audit Objective-C++ code for unsafe shared mutable state and thread-safety bugs by scanning the codebase for common concurrency anti-patterns and prioritizing findings based on deadlock potential and data race likelihood.

Can I scan an existing Objective-C project directory for queue misuse without modifying the code?▼

Yes, you can run a static concurrency scan on an existing directory to analyze threading patterns and identify potential queue misuse, outputting the results to a temporary file without modifying the source code.

How are concurrency defects prioritized when auditing Objective-C threading patterns?▼

Concurrency defects are prioritized based on risk, specifically evaluating deadlock potential and data race likelihood to highlight the most dangerous thread-safety issues first.
