SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill addresses the challenge of ensuring code quality by performing intelligent mutation testing, identifying potential issues that existing tests might miss.

Core Features & Use Cases

  • Mutation Testing: Analyzes code changes for potential issues that could slip through existing tests.
  • Inspector Sub-Skill: Operates as a sub-skill within the Inspector phase of the LFE pipeline.
  • No Test Runner Needed: Uses AI reasoning to determine if hypothetical code mutations would be caught by tests.
  • Use Case: When a developer makes changes to the codebase, this Skill can be used to verify that the changes do not introduce new bugs that existing tests might miss.

Quick Start

Run /lfe-inspector to enable mutation testing for your code changes.

FAQPage Schema
How do I perform mutation testing without a test runner?

AI-driven mutation testing analyzes code changes by reasoning about hypothetical mutations to identify issues existing tests might miss. This approach operates within the LFE pipeline without requiring a test runner to verify code quality.

How do I run mutation testing on code changes in the LFE pipeline?

Run the `/lfe-inspector` command to enable mutation testing for your code changes within the LFE pipeline. This activates the Inspector sub-skill, which uses AI reasoning to verify that changes do not introduce bugs that existing tests might miss.

What is AI reasoning mutation testing and how does it work?

AI reasoning mutation testing is a technique that analyzes hypothetical code mutations to find issues existing tests might miss. Instead of executing a test runner, it uses AI to reason about whether current tests would catch the mutated code, identifying potential gaps in test coverage.

Do I need a test runner to verify code quality with mutation testing?

No, you do not need a test runner to verify code quality with this mutation testing approach. The Skill uses AI reasoning within the LFE pipeline to analyze whether hypothetical code mutations would be caught by existing tests, eliminating the test runner requirement.

When should I use AI mutation testing for my codebase?

You should use AI mutation testing when a developer makes changes to a codebase and needs to verify that the changes do not introduce new bugs that existing tests might miss. It operates within the LFE pipeline as an Inspector sub-skill to ensure code quality during development.
