# Laravel Packages

Package development: extracting reusable patterns for use across projects.

**Related guides:**
- [package-extraction.md](references/package-extraction.md) - Extracting code into packages
- [DTOs](../laravel-dtos/SKILL.md) - Using Spatie Laravel Data
- [Models](../laravel-models/SKILL.md) - Using Spatie Model States and Query Builder

## When to Extract

Extract to package when:
1. Pattern used in 3+ projects
2. Code is stable and well-tested
3. Pattern has clear boundaries
4. Maintenance cost justified
