Codebase Implementation

Getting Started

1. Copy the product-plan/ folder into your target codebase
2. Start your AI coding agent (Claude Code, Cursor, etc.)
3. Choose your implementation approach below

Implementation Approaches

Choose the approach that best fits your project:

• Incremental Implementation — Recommended for larger products or when you want to review progress section by section.
• One-Shot Implementation — For simpler products or when you want to build everything in one session.

Start with Plan Mode

The provided prompts assume you'll deliver them to Claude Code (or Cursor) in Plan mode. This encourages the agent to:

• Analyze the instructions and design specifications thoroughly
• Ask clarifying questions about functional requirements
• Build a complete implementation plan that works for your specific codebase and tech stack

Once you're satisfied with the plan, give your agent the go-ahead to begin implementation.

Implementation Instructions

The provided prompts, instruction files, and referenced assets are designed to instruct your agent to:

• Read and analyze the design specifications before writing code
• Use the provided UI components as-is—don't redesign or restyle them
• Follow the data model types defined in the export
• Implement backend: database schema, API endpoints, business logic
• Use test-driven development with the provided tests.md instructions
• Handle empty states and error states gracefully
• Use sample data for initial testing before building real APIs
• Ask clarifying questions about auth, user modeling, and integration points

Tips

• Use the pre-written prompts — They include important clarifying questions about auth and data modeling.
• Add your own notes — Customize prompts with project-specific context when needed.
• Build on your designs — Use completed sections as the starting point for future feature development.
• Review thoroughly — Check plans and implementations carefully to catch details and inconsistencies.
• Fill in the gaps — Backend business logic may need manual additions. Incremental implementation helps you identify these along the way.
