5-Phase Workflow

A systematic, AI-assisted feature development workflow for Claude Code that works with any tech stack.

What is This?

The 5-Phase Workflow is a structured approach to feature development that breaks down the process into clear, manageable phases:

1. Feature Planning - Understand requirements through intensive Q&A
2. Implementation Planning - Map requirements to technical components
3. Orchestrated Implementation - Execute with state tracking and parallel processing
4. Verify Implementation - Automated verification of completeness and correctness
5. Code Review - AI-powered review and quality improvements

Why Use It?

• Systematic: Clear phases prevent missing requirements or skipping validation
• Efficient: Parallel execution and smart agents minimize context usage
• Resumable: State tracking allows pausing and continuing work across sessions
• Technology-Agnostic: Works with JavaScript, Python, Java, Go, Rust, and more
• Transparent: Visible progress tracking and clear handoffs between phases

Installation

Install the workflow in your project using npx:

# Install locally in current project
npx 5-phase-workflow

# Or install globally for all projects
npx 5-phase-workflow --global

The installer will:

• Auto-detect your project type (JavaScript, Python, Java, etc.)
• Copy workflow commands, agents, and skills to .claude/
• Create a config file at .claude/.5/config.json
• Configure build and test commands for your project

Quick Start

After installation, configure the workflow for your project:

# Open Claude Code in your project
# Run the configuration wizard
/5:configure

Then start your first feature:

# Phase 1: Plan the feature
/5:plan-feature

# Phase 2: Create implementation plan
/5:plan-implementation {ticket-id}-{description}

# Phase 3: Execute implementation
/5:implement-feature {ticket-id}-{description}

# Phase 4: Verify implementation
/5:verify-implementation

# Phase 5: Review code
/5:review-code

Supported Tech Stacks

The workflow auto-detects and supports:

JavaScript/TypeScript:

• Node.js (npm, yarn, pnpm)
• Next.js
• NestJS
• Express
• React
• Vue

Python:

• Django
• Flask
• FastAPI
• Generic Python projects

Java:

• Gradle
• Maven
• Spring Boot

Other:

• Rust (Cargo)
• Go
• Ruby on Rails
• Custom projects (via manual config)

Available Commands

All commands are available under the /5: namespace:

Configuration

The workflow is configured via .claude/.5/config.json. Here's an example:

{
  "projectType": "nextjs",
  "ticket": {
    "pattern": "[A-Z]+-\\d+",
    "extractFromBranch": true
  },
  "build": {
    "command": "npm run build",
    "testCommand": "npm test"
  },
  "steps": [
    { "name": "foundation", "mode": "parallel" },
    { "name": "logic", "mode": "sequential" },
    { "name": "integration", "mode": "sequential" }
  ],
  "reviewTool": "coderabbit"
}

Configuration Options

Required Fields

• projectType: Detected project type (e.g., "nextjs", "django", "rust")
• build.command: Command to build the project
• build.testCommand: Command to run tests

Optional Fields

• ticket.pattern: Regex pattern for ticket IDs (e.g., "PROJ-\\d+")
• ticket.extractFromBranch: Auto-extract ticket from branch name
• steps: Implementation step configuration
• framework: Framework-specific patterns (routes, models, etc.)
• integration: Integration point configuration
• tools: Available development tools (CodeRabbit, IDE, etc.)

Run /5:configure to set up or update your configuration.

How It Works

Phase 1: Feature Planning

Claude asks 5-10 clarifying questions to understand your requirements:

• What exactly should this feature do?
• What are the edge cases?
• How will we verify it works?
• Are there simpler alternatives?

The output is a comprehensive feature spec at .claude/.features/{ticket-id}.md.

Phase 2: Implementation Planning

Claude maps your feature to technical components:

• Analyzes your codebase structure
• Identifies affected modules
• Maps components to implementation steps
• Creates dependency graph

The output is a detailed plan at .claude/.implementations/plans/{ticket-id}.md.

Phase 3: Orchestrated Implementation

Claude executes the plan using specialized agents:

• step-executor: Creates each component using skills or direct file creation
• step-verifier: Compiles and checks for errors after each step
• integration-agent: Wires components and registers routes

State is tracked in .claude/.implementations/state/{ticket-id}.json for resumability.

Phase 4: Verify Implementation

An agent performs comprehensive verification:

• All planned files exist
• No compilation/build errors
• Tests pass
• IDE diagnostics clean

Results are saved to a verification report.

Phase 5: Code Review

Automated review using CodeRabbit (if installed):

• Finds code smells and potential issues
• Suggests improvements
• Applies approved fixes
• Re-verifies after changes

After installation, your .claude/ directory will contain:

Examples

Example 1: Adding a REST API endpoint

/5:plan-feature
# Claude asks about the endpoint: path, methods, request/response format, validation, etc.
# Creates feature spec

/5:plan-implementation PROJ-1234-add-user-endpoint
# Claude maps to: route file, controller, service, tests
# Creates technical plan

/5:implement-feature PROJ-1234-add-user-endpoint
# Creates route, controller, service, tests
# Registers route in app
# Runs build and tests

/5:verify-implementation
# Verifies all files created
# Checks build passes
# Confirms tests pass

Example 2: Small bug fix

/5:quick-implement
# Describe the fix
# Claude implements, builds, tests in one step

Troubleshooting

Build/Test commands not working

1. Run /5:configure to verify configuration
2. Test commands manually in terminal
3. Update .claude/.5/config.json with correct commands

"Cannot find project type"

The auto-detection failed. Run /5:configure and manually select your project type.

State file issues

If implementation gets stuck:

1. Check .claude/.implementations/state/{ticket-id}.json
2. Note the currentStep value
3. Run /5:implement-feature again - it will resume from that step

CodeRabbit not working

1. Install: https://docs.coderabbit.ai/cli/installation
2. Authenticate: coderabbit auth login
3. Run /5:configure to update config

Updating

To upgrade to the latest version:

# Uninstall current version
npx 5-phase-workflow --uninstall

# Reinstall latest
npx 5-phase-workflow

Your configuration in .claude/.5/config.json will be preserved.
