clean-code-ch03-functions

What problem does it solve?

Functions often become bloated, hard to read, and difficult to maintain as codebases grow. This skill provides a practical, checklist-driven approach to enforce small size, single responsibility, proper abstraction, and other best practices from Clean Code Ch3.

Core Features & Use Cases

• Size & SRP enforcement: checks for 20 lines or fewer and a single responsibility.
• Abstraction & naming discipline: ensures consistent abstraction levels and descriptive names.
• CQS & error handling patterns: guidance on command-query separation and exception-based error handling.
• Code review & refactoring support: provides a repeatable process for code reviews and incremental improvements.
• Use case: When reviewing a function in PRs, apply the checklist to decide if it is clean or needs refactoring.

Quick Start

Run the function-quality-checks tool on a target codebase and follow the on-screen checklist prompts.
