    Example session with this skill installed

    My Jest tests for the auth controller are failing with a 401 unauthorized error after I updated the middleware. Can you fix it?

    • Read your context and instructions
    • Compiled the fix failing tests

    **Test Failure Summary:** Auth controller tests failing with 401 status. **Likely Root Cause:** Missing header mapping in the updated middleware. **Fixes Applied:** Updated auth-middleware.js to correctly parse Bearer tokens. **Verification Result:** All 4 tests in auth.spec.js passed.

    About this skill

    The problem

    Debugging test failures is a time-consuming distraction that breaks development flow. Manually tracing stack traces to source code often leads to oversized fixes or unnecessary test suppressions.

    What it does

    • Analyzes test error output to map failures to specific source lines.
    • Identifies root causes by cross-referencing test assertions with implementation logic.
    • Applies the smallest possible safe fix to source code or configuration.
    • Verifies resolutions by automatically rerunning the affected test suite.
    • Generates a structured summary of modifications and verification results.

    Why this beats prompting it yourself

    Generic prompts often lead to agents deleting failing tests or performing broad refactors that introduce new bugs. This skill enforces a strict "source-first" fix logic and requires verification runs, ensuring the suite passes because the code works, not because the tests were weakened.

    Use cases

    • Fixing unit tests that broke after a dependency update or refactor.
    • Debugging integration test failures in CI/CD pipelines.
    • Resolving configuration issues in test runners or environment setups.
    • Restoring passing status to a legacy test suite with minimal code changes.

    Frequently Asked Questions

    This skill supports most major testing frameworks including Jest, Pytest, Mocha, and Vitest, and can be integrated into any AI agent capable of file system access and shell execution.

    No, the skill prioritizes "source-first" logic, meaning it aims to fix the underlying implementation; it will only modify the test file if it detects an outdated assertion or a configuration error.

    The skill requires read/write access to your source code and the ability to execute your project's test command (e.g., `npm test` or `pytest`) to verify its fixes.

    By purchasing this skill, you receive the production-ready logic for autonomous test repair, documentation for integration, and access to any future version updates or optimizations.

    Yes, because it analyzes the actual error output and stack traces, it can identify and resolve configuration mismatches and environment-specific failures in addition to logic bugs.

    The skill is designed to perform the smallest safe fix possible and automatically reruns the affected tests to ensure the solution is valid before finalizing the changes.
