# Implementation Handoff

Everything an engineer needs to start building

Engineering Partner

Packages your specs, prototype, reviews, and design tokens into a structured handoff document ready for a coding agent or developer to implement.

## How it works

1. ### Gather the artifacts  
   The agent collects everything produced during the project: specs, prototypes, review feedback, design tokens, and decisions.

2. ### Structure the handoff  
   Artifacts are organized into a structured package: component specs, interaction details, edge cases, design tokens, and open questions.

3. ### Hand off to implementation  
   The package is ready for a coding agent or developer to pick up. Everything needed to build is in one place.

## Why use Implementation Handoff

### Nothing gets lost  
Every decision, review finding, and edge case from the design process is captured in the handoff.

### Agent-ready  
Structured for coding agents to consume directly — no human translation layer needed.

### Complete context  
Engineers understand not just what to build, but why each decision was made and what was considered.

### Reduced back-and-forth  
Comprehensive handoffs eliminate the "one more question" cycle between design and engineering.

## When to use Implementation Handoff

### Feature handoff to engineering  
A design is approved and ready for implementation. You need to hand it off cleanly.  
Package the checkout redesign for handoff. Include the prototype, spec, review feedback, and all design tokens.

### Coding agent input  
You want a coding agent to implement the design and need to provide structured context.  
Generate a handoff package for the settings page redesign that a coding agent can use to implement it directly.

### Contractor briefing  
An external developer needs to implement a design without access to your team for questions.  
Create a self-contained handoff document for the notification system redesign. Include everything needed to build it independently.
