I Won’t Use AI Without This Tool

A walkthrough of Knip, a free CLI tool that detects dead code, duplicate code, and code complexity issues in JavaScript/TypeScript projects. The tool works similarly to ESLint but is specifically designed to catch problems common in AI-generated code such as unused exports, duplicated logic, and bloated files. The tutorial covers running Knip from the command line, using the VS Code extension, integrating it with AI agents via skills, setting up CI/CD pipelines with GitHub Actions, configuring ignore patterns, and using the audit mode to compare changes between branches.
