# Bob needs to add user registration, decomposed into:

Step 1: "Create User model with email, password_hash, created_at fields"
Step 2: "Implement registration API endpoint POST /api/register with email format validation"
Step 3: "Add password hashing using bcrypt"
Step 4: "Write integration tests for the registration flow"
Step 5: "Add email verification flow"

> 1. Replace all route definitions
> 2. Update middleware syntax
> 3. Modify startup scripts
> 4. Ensure all tests pass
> 5. Update package.json

# Alice's hybrid workflow

1. [Question] "What's the auth architecture of this project?"
2. [Question] "What are the best practices for JWT refresh tokens?"
3. [Task] "Add a JWT refresh token endpoint"
4. [Task] "Write unit tests for refresh tokens"
5. [Agent] "Review the entire auth module, fix all security issues"
