# Work Unit Decomposition

## Overview

Break implementation plans into discrete, testable work units. Each unit has enumerated Definition of Done items, declared file scope, dependency mapping, and optional human checkpoint flags.

## When to Use

- After plan review gate approval
- When decomposing a large feature into implementable chunks
- When preparing for orchestrated execution

## Work Unit Structure

Each work unit specifies:
- **ID** - Unique identifier
- **Title** - Human-readable description
- **Definition of Done** - Enumerated checklist items
- **File Scope** - Which files the unit may modify
- **Dependencies** - Other work units this depends on
- **Human Checkpoint** - Whether human approval is needed before execution
- **Parallel Safe** - Whether it can execute alongside other units

## Human Checkpoint Triggers

Mark human checkpoints for:
- Schema or database changes
- Security-sensitive code paths
- New architectural patterns not seen in codebase
- External API integrations
- Breaking changes to public interfaces

## Agents Used

- `agents/architect/` - Creates the decomposition
- `agents/cto/` - Validates TDD readiness per unit
