About this plugin

This plugin runs a structured seven-phase workflow for building features. The /feature-dev command helps clarify requirements, explores the existing codebase with specialised agents, identifies open questions, compares architectural approaches and reviews the resulting implementation.

Reach for it when a feature needs more planning than a direct coding request. The workflow is interactive and uses separate agents for codebase exploration, architecture design and code review.

What's inside

  • 1 slash command: /feature-dev
  • 3 agents: code-explorer, code-architect and code-reviewer
  • 0 skills, 0 hooks and 0 MCP servers
