package-first-development

What problem does it solve?

This Skill prevents developers from wasting time building features that already exist, thereby reducing development time, minimizing bugs, and lowering maintenance costs.

Core Features & Use Cases

• Automated Package Discovery: Uses Context7 and WebSearch to find battle-tested libraries and frameworks for common functionalities (e.g., form validation, date manipulation, authentication).
• Quality Evaluation: Guides you through evaluating packages based on popularity, maintenance, quality (documentation, TypeScript support), and compatibility.
• Use Case: When you need to add a new feature like "image cropping" to your React application, this skill will search for existing solutions, evaluate react-easy-crop vs. react-image-crop, and recommend the best fit, saving you days of custom development.

Quick Start

Ask Claude to find a package for a new feature:
