The Four-Phase Approach

Claude Code excels when you follow this structured approach to feature development:

graph LR
    A[1. Understand] --> B[2. Plan]
    B --> C[3. Implement]
    C --> D[4. Review & Commit]

Phase 1: Understand the Requirements

# Start with context gathering
claude> "Read the issue #123 requirements and related code"
 
# Ask clarifying questions
claude> "What edge cases should we consider for this feature?"
 
# Research similar implementations
claude> "Show me how we handle similar features elsewhere in the codebase"

Phase 2: Plan the Implementation

# Create a detailed plan
claude> "Create a step-by-step plan for implementing user notifications"
 
# Example response structure:
# 1. Database schema changes
# 2. API endpoints
# 3. Frontend components
# 4. State management
# 5. Tests

Phase 3: Implement with TDD

# Start with tests
claude> "Write tests for the notification service based on our plan"
 
# Implement incrementally
claude> "Now implement the notification service to make these tests pass"
 
# Request code review
claude> "Review this implementation for potential issues"

Phase 4: Commit and Document

# Create meaningful commit
claude> "Create a commit for these changes with a detailed message"
 
# Update documentation
claude> "Update the README with the new notification feature"
 
# Create PR if needed
claude> "Create a pull request for this feature"

Real-World Example: Adding Search Functionality

# Phase 1: Understand
claude> "I need to add search functionality to our product catalog. Read the current catalog implementation"
 
# Phase 2: Plan
claude> "Create a plan for adding full-text search with filters"
 
# Claude's response:
# 1. Add search index to database (PostgreSQL full-text search)
# 2. Create SearchService with query builder
# 3. Add /api/products/search endpoint
# 4. Build SearchBar component with debouncing
# 5. Implement search results page with pagination
 
# Phase 3: Implement
claude> "Let's start by writing tests for the SearchService"
claude> "Now implement the SearchService"
claude> "Create the search API endpoint"
claude> "Build the SearchBar component with proper debouncing"
 
# Phase 4: Review & Commit
claude> "Review all the search implementation for performance issues"
claude> "Create commits for the search feature"

πŸ› 2. Debugging Workflow

Systematic Debugging Process

    A[Reproduce Issue] --> B[Gather Information]
    B --> C[Form Hypothesis]
    C --> D[Test Hypothesis]
    D --> E{Fixed?}
    E -->|No| C
    E -->|Yes| F[Verify & Document]

Step 1: Reproduce and Isolate

# Describe the issue
claude> "Users report the checkout button sometimes doesn't work. Let me investigate"
 
# Reproduce
claude> "Run the checkout flow and look for issues"
 
# Isolate
claude> "Create a minimal test case that reproduces the checkout button issue"

Step 2: Gather Diagnostic Information

# Analyze error logs
claude> "Check the error logs for checkout-related issues"
 
# Examine code
claude> "Review the checkout button click handler and related code"
 
# Check recent changes
claude> "What recent commits touched the checkout functionality?"

Step 3: AI-Assisted Analysis

# Stack trace analysis
claude> "Analyze this stack trace: [paste trace]"
 
# Pattern recognition
claude> "Are there patterns in when this checkout issue occurs?"
 
# Root cause analysis
claude> "Based on the evidence, what's the most likely cause?"

Step 4: Implement and Verify Fix

# Fix the issue
claude> "Implement a fix for the race condition in checkout"
 
# Add regression test
claude> "Write a test that would have caught this issue"
 
# Verify comprehensively
claude> "Run all checkout-related tests to ensure nothing broke"

Debugging Example: Memory Leak

# Initial report
claude> "The app becomes slow after extended use. Investigate potential memory leaks"
 
# Gather information
claude> "Add memory profiling to track heap usage over time"
 
# Analyze patterns
claude> "Analyze these memory snapshots and identify growing objects"
 
# Claude identifies issue:
# "I found event listeners being added but not removed in the Modal component"
 
# Implement fix
claude> "Fix the memory leak by properly cleaning up event listeners"
 
# Verify
claude> "Add tests to ensure event listeners are properly cleaned up"
