Feature Flow

Feature-Flow

**Incremental feature development workflow for existing codebases.**

Feature-flow is a Claude Code plugin that automates the full lifecycle of adding features to an existing system — from analysis through implementation, testing, security audit, code review, and PR delivery.

The Problem

[sprint-flow](https://github.com/skybao1024/sprint-flow) solves **0→1**: building a complete system from a PRD. But real software development is 90% iteration. After the system exists, you need a different workflow that:

• Understands existing architecture before writing code
• Follows existing patterns, design systems, and conventions
• Maps dependencies to avoid breaking changes
• Validates with tests and security audits
• Delivers via git branches and pull requests
• Preserves context for efficient debugging

**Feature-flow solves 1→N.**

How It Works

─────────────────          ──────────────────
PRD → System               Feature-PRD → Feature Branch → PR
                            ↓
                            Analyze codebase
                            Plan implementation
                            Implement (backend + frontend)
                            Test + Security audit
                            Code review
                            Create PR
                            Debug (if needed)

Commands

Command	Purpose
/feature-init	Analyze Feature-PRD + codebase, produce implementation plan
/feature-run [name]	Execute implementation (one-shot: all phases)
/feature-status [name]	Show progress and state
/feature-review [name]	Code review before PR
/feature-done [name]	Push branch, create PR, update global analysis
/feature-debug "issue"	Debug with preserved context
/feature-sync	Refresh global project analysis manually

Quick Start

1. Write a Feature-PRD

Use the templates in `t
