What metrics are used to identify a problematic class?

The skill primarily looks for classes exceeding 400 lines of code or hosting more than 20 public methods, while also analyzing cyclomatic complexity.

What programming languages does the detect-god-class skill support?

The skill supports a wide variety of languages including TypeScript, JavaScript, Python, Java, C#, Ruby, and Go.

What triggers the God Class detection process?

It is an automated skill that triggers whenever a code change is detected in any of the supported file extensions.

Does this skill provide suggestions on how to fix the code?

Yes, in addition to flagging the class, it provides decomposition strategies to help you break the module into smaller, more focused components.

Developer Tools

Identifies oversized classes and modules that violate the single-responsibility principle to improve code maintainability.

The detect-god-class skill acts as an automated architectural auditor for your codebase, specifically designed to identify monolithic 'God Classes' that have grown too complex. By monitoring code changes across multiple languages—including TypeScript, Python, Java, and Go—it analyzes static metrics like lines of code, cyclomatic complexity, and public API surface area. When a class exceeds defined thresholds or appears to host unrelated responsibilities based on naming heuristics, the skill flags the file and provides specific evidence alongside actionable decomposition strategies to help you refactor toward a more modular architecture.
