# Architecture Planning

Design before implementing.

## Step 1: Requirements

- Document user stories
- Define acceptance criteria
- Identify constraints

## Step 2: Research

- Check existing implementations
- Review similar patterns in codebase
- Consult library docs

## Step 3: Design

- Create module structure
- Define interfaces and contracts
- Plan data models

## Step 4: Risk Assessment

- Identify integration points
- Check backward compatibility
- Plan rollback strategy

## Step 5: Task Breakdown

- Atomic, testable tasks
- Dependency ordering
- Estimate effort

## Output Artifacts

- spec.md - WHAT and WHY
- plan.md - HOW
- tasks.md - DO sequence
