Example: Building a REST API

AWS Kiro Approach

# 1. Write specification
apiVersion: kiro.aws/v1
kind: Specification
metadata:
  name: user-api
spec:
  requirements:
    - id: API-001
      description: |
        WHEN a client requests user data
        THEN return user profile with posts
        AND include pagination support

# 2. Generate code
kiro generate

# Result: Complete API with tests, docs, and deployment config

Devin Approach

# Natural language request
"Build a REST API for user management with:
- User profiles
- Posts functionality  
- Pagination
- Tests
- Deploy to AWS"

# Devin autonomously:
- Researches best practices
- Writes code
- Tests implementation
- Debugs issues
- Deploys application
