Can it handle complex integration tests?

Yes, it traces through implementation paths and reviews stack traces to understand the context of the failure across various layers of your application.

Why would a test be classified as 'Ambiguous'?

A failure is classified as Ambiguous when the test and implementation disagree, but the intended 'correct' behavior isn't clearly defined in the API design or documentation.

Is this skill compatible with all testing frameworks?

Yes, it is framework-agnostic, focusing on the underlying logic, assertions, and error messages rather than specific library syntax.

How does this skill differ from standard debugging?

It uses a structured investigative framework to specifically determine if the failure lies in the test code itself, the production implementation, or an ambiguity in requirements.

Does it automatically fix the code?

It provides specific, reasoned recommendations and logic explanations for the fix, which you can then choose to apply to your codebase.

Security & Testing

Debugs and classifies failing test cases to determine if they indicate genuine implementation bugs or incorrect test expectations.

The Test Failure Analyzer skill provides a structured, investigative framework for Claude to systematically diagnose why tests are failing. Instead of defaulting to the assumption that a test is 'wrong,' this skill guides the AI to analyze the intent of the test, trace the implementation logic, and evaluate the failure against documented behavior. It helps developers maintain high software quality by accurately classifying issues as implementation bugs, test bugs, or ambiguous requirements and providing specific recommendations for resolution.
