SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill identifies and reports on unhandled edge cases and branching paths within code, ensuring greater robustness and fewer unexpected errors.

Core Features & Use Cases

Exhaustive Path Enumeration: Mechanically traces every possible execution path and boundary condition in code.
Guard Detection: Reports only paths that lack explicit guard clauses or error handling.
Use Case: After implementing a new feature, use this Skill to scan the changes for any potential edge cases that might have been missed, such as null inputs or boundary value errors.

Quick Start

Use the insight-edge-case-hunter skill to hunt edge cases in the current git diff.

FAQPage Schema

How do I find unhandled edge cases in my code?▼

Finding unhandled edge cases requires mechanically tracing every possible execution path and boundary condition in your code. This exhaustive path enumeration identifies missing guard clauses and reports unguarded branches alongside suggested guard snippets.

What is the best way to check a git diff for missing guard clauses?▼

The best way to check a git diff for missing guard clauses is to apply exhaustive path enumeration to the changes. This mechanically traces new branches and inputs to isolate unguarded paths and provides targeted guard snippets to resolve boundary value errors.

How does path enumeration identify boundary value errors during code review?▼

Path enumeration identifies boundary value errors by mechanically tracing all possible execution paths and inputs within the code. During a code review, it specifically targets and reports paths that lack explicit guard clauses or error handling for those boundary conditions.

Can I use exhaustive path enumeration for function-level checks?▼

Yes, you can use exhaustive path enumeration for function-level checks. It applies mechanical tracing to every branch and input within a specific function, reporting any unguarded paths and missing guard clauses to ensure robust error handling.

Why does my code fail when tracing unguarded paths for null inputs?▼

Code fails on unguarded paths for null inputs when explicit guard clauses are missing. Exhaustive path enumeration detects these missing guards by mechanically tracing inputs and boundary conditions, reporting the exact unhandled branches that cause unexpected errors.
