Use Cases

Scenario	You say	DevCrew does
Greenfield	"I have an idea, build from scratch"	Init → guide requirements → Standard
Existing PRD	"Here's the PRD, execute it"	Import PRD → refine → Standard
Mid-project	"Code exists, help me continue"	Scan code → establish baseline → Standard
Brainstorm	"Let's discuss the approach"	Explore mode (no code changes)
Bug fix	"There's a bug, fix it fast"	Express mode
Refactor	"This code needs refactoring"	Standard (full workflow)
Prototype	"Build a quick prototype first"	Prototype mode
Learn codebase	"Help me understand this code"	Explore mode (code analysis)

Greenfield

When you have a new idea, tell the AI. DevCrew auto-enters Standard mode:

1. Plan — AI guides you through requirements, defines acceptance criteria
2. Design — Generates technical design and task breakdown
3. Execute — Code implementation
4. Verify — Automated testing and code review
5. Iterate — Issues auto-fixed

Bug Fix

Bug fixes use Express mode (skip Design):

1. Plan — Locate issue, confirm fix target
2. Execute — Code the fix
3. Verify — Validate the fix

Quick Prototype

Prototyping uses Prototype mode (skip Verify + Iterate):

1. Plan — Define prototype goals
2. Design — Quick technical approach
3. Execute — Rapid implementation
