What problem does it solve? Adding a new feature to an existing codebase often fails due to missed context, unasked questions, and inconsistent architecture choices. This Skill structures the entire feature development lifecycle so nothing is skipped: codebase exploration, clarifying questions, architecture comparison, implementation, and quality review. ## Core Features & Use Cases - Parallel Codebase Exploration: Launches multiple code-explorer subagents to map similar features, architecture, and testing patterns, then reads the key files they identify. - Structured Clarifying Questions: Surfaces underspecified aspects like edge cases, error handling, and integration points before any design work begins. - Architecture Comparison: Generates minimal, clean, and pragmatic design options via code-architect subagents and presents them in a comparison table with a recommendation. - Multi-Agent Quality Review: Runs three code-reviewer subagents focused on simplicity, correctness, and project conventions after implementation. - Use Case: When asked to add a new API endpoint to an existing service, the Skill explores how similar endpoints are built, asks about auth and error handling requirements, compares design approaches, implements the chosen one, and reviews the result. ## Quick Start Ask the agent to implement a new feature or user story in your codebase, for example: implement a password reset endpoint following the feature-dev workflow.
