# Improve Code Quality

It works on your machine and you are afraid to touch it

## What this does

You have something that works but no tests, and every change feels like a gamble. This walks you through hardening it phase by phase: get tests in, clean up the structure, draw a boundary around the business rules, and make it hold up under load. It asks questions as it goes and writes the answers into your project's docs folder.

### Top 3 things it does for you

- Add tests before you start refactoring
- Make a prototype safe to change
- Harden AI-generated code for production

## About Improve Code Quality

This is a guided journey from a working-but-untested vibe-coded prototype to a production-ready product with tests, clean structure, a business-rules boundary, and resilience at scale. It orchestrates nine skills phase by phase - working-with-legacy-code, clean-code, refactoring-patterns, software-design-philosophy, clean-architecture, pragmatic-programmer, release-it, system-design, and ddia-systems - asking you questions at every decision point.

Results are recorded in the project docs folder, in TESTING.md, TECH-DEBT.md, RELIABILITY.md, and IMPROVE-CODE-QUALITY-PLAN.md, so the journey resumes across sessions. It fits hardening an AI-generated prototype, adding tests before refactoring, and making code safe to change.

For a large aged codebase, use remove-technical-debt. To decide structure before building, use design-code-architecture. For a product and UX pass, use improve-app. For one framework in isolation, invoke that skill directly.
