Documentation
Full READMEFeature Development Plugin
A comprehensive, structured workflow for feature development with specialized agents for codebase exploration, architecture design, and quality review.
Overview
The Feature Development Plugin provides a systematic 7-phase approach to building new features. Instead of jumping straight into code, it guides you through understanding the codebase, asking clarifying questions, designing architecture, and ensuring quality—resulting in better-designed features that integrate seamlessly with your existing code.
Philosophy
Building features requires more than just writing code. You need to:
- Understand the codebase before making changes
- Ask questions to clarify ambiguous requirements
- Design thoughtfully before implementing
- Review for quality after building
This plugin embeds these practices into a structured workflow that runs automatically when you use the /feature-dev command.
Command: /feature-dev
Launches a guided feature development workflow with 7 distinct phases.
Usage:
/feature-dev Add user authentication with OAuthOr simply:
