# Bundle Checker
Your bundle is 2MB and you don't know why. This tool analyzes your build output and tells you exactly what's eating up space and how to fix it.
**One command. Zero config. Just works.**
## Quick Start
```bash
npx ai-bundle-check
```
## What It Does
- Analyzes your bundle composition
- Identifies the largest dependencies
- Suggests tree-shaking opportunities
- Recommends lighter alternatives
## Usage Examples
```bash
# Analyze current project
npx ai-bundle-check
# Analyze specific directory
npx ai-bundle-check ./my-project/
# Get detailed breakdown
npx ai-bundle-check --verbose
```
## Best Practices
- **Check before shipping** - catch size regressions early
- **Consider alternatives** - moment.js vs date-fns makes a huge difference
- **Dynamic imports** - split code that isn't needed immediately
- **Monitor trends** - track bundle size in CI
## When to Use This
- Your app loads slowly and you suspect the bundle
- Adding a new dependency and want to check the impact
- Performance audit flagged JavaScript size
- CI bundle size check is failing

## Requirements
No install needed. Just run with npx. Node.js 18+ recommended. Needs OPENAI_API_KEY environment variable.
```bash
npx ai-bundle-check --help
```
## How It Works
Scans your package.json and build output, identifies heavy dependencies, and sends the analysis to GPT-4o-mini. The AI knows common bundle bloat patterns and suggests specific optimizations like switching libraries or adding tree-shaking config.

This skill analyzes your build output and tells you exactly what is inflating your bundle and how to reduce it. It combines static inspection of package files and compiled assets with AI-driven recommendations to highlight the biggest offenders and concrete fixes. Use it with minimal setup—one command and no configuration required.
The tool scans package metadata and your build directory to compute size contributions per file and dependency. It identifies large modules, unused exports, and patterns that prevent tree-shaking, then sends a focused analysis to an AI model which returns prioritized suggestions like swapping libraries, changing import styles, or enabling code splitting. Results include a ranked breakdown, actionable fixes, and command examples to implement optimizations.
Do I need special configuration to run it?
No—one command runs with sensible defaults. You can pass a path or verbosity flags for more detail.
Does it modify my code automatically?
No—the tool provides recommendations and code examples. Apply changes yourself or via your preferred automation.
