# Deps Analyzer

Your package.json has 87 dependencies and you use maybe 40 of them. This tool finds the dead weight and tells you what to do about it.

**One command. Zero config. Just works.**

## Quick Start

```bash
npx ai-deps
```

## What It Does

- Finds unused dependencies you can remove
- Flags outdated packages with security issues
- Explains what each problematic dependency does
- Can auto-fix by removing unused deps

## Usage Examples

```bash
# Audit current project
npx ai-deps

# Auto-remove unused deps
npx ai-deps --fix

# Check a specific directory
npx ai-deps --dir ./my-project
```

## Best Practices

- **Run before major updates** - clean slate before upgrading
- **Check devDependencies too** - test tools get stale
- **Review before fixing** - some deps are used dynamically
- **Update lockfile after** - run npm install after removals

## When to Use This

- Your install is taking forever
- Bundle size is way too big
- npm audit has 47 warnings
- You inherited a project with mystery deps

## How It Works

Runs depcheck to find unused dependencies and npm outdated to find stale ones. Sends the results to GPT-4o-mini for analysis, which explains each issue and prioritizes what to fix first.
