SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill removes unnecessary code from a repository, ensuring that only the functionality exercised by your tests remains, thereby reducing complexity and improving maintainability.

Core Features & Use Cases

Codebase Slimming: Safely eliminate dead code, unused files, and redundant functions.
Test-Driven Optimization: Relies entirely on test coverage to determine which code is essential.
Use Case: You have a large legacy codebase with many features that are no longer used or tested. This Skill can help you identify and remove that unused code, making the codebase smaller, faster to build, and easier to understand.

Quick Start

Use the test-guided-debloating skill to analyze the coverage report 'coverage.json' and identify code for removal.

FAQPage Schema

How do I remove dead code from a legacy codebase using test coverage?▼

Removing dead code using test coverage involves parsing coverage reports to identify unexercised functions and files. This Skill analyzes coverage data to determine which code is essential, safely eliminating unused files and redundant functions from your repository.

What is test-guided debloating and how does it slim down code?▼

Test-guided debloating is a software maintenance technique that reduces codebase complexity by eliminating dead code. It parses coverage reports to identify unused functions and files, ensuring only functionality exercised by your tests remains to improve maintainability.

Can I use this debloating approach for JavaScript and Java projects?▼

Yes, you can use this test coverage analysis approach for JavaScript and Java projects, as well as Python. It applies to software maintenance and optimization tasks across these languages to identify and eliminate unused code, functions, and files.

Do I need a coverage analysis tool to identify unused files and functions?▼

Yes, you need coverage analysis tools and scripts to parse coverage reports. The Skill requires coverage data, such as a coverage.json file, to guide the removal process and accurately identify dead code for elimination.

What are the limitations of relying on test coverage for codebase optimization?▼

Relying on test coverage for codebase optimization means untested but necessary code might be flagged for removal. This approach assumes your tests comprehensively cover essential features, so insufficient test coverage can lead to the accidental elimination of required functionality.
