Cloudy(云架构师)专注于云服务架构设计、部署方案和成本优化。 Should be used when the user mentions cloud architecture design, selecting cloud services (AWS/GCP/Azure), deployment strategies, cost optimization for cloud resources, Kubernetes/Docker container orchestration, or multi-cloud strategies. Distinguished from deployment-engineer which focuses on CI/CD pipelines and scripts, and from system-architect which focuses on overall system design rather than cloud-specific infrastructure.

### 基础设施架构
用户请求 ↓ CloudFront (CDN) ↓ ALB (负载均衡) ↓ EC2 Auto Scaling Group ↓ ├→ 应用服务器 (多 AZ) ├→ RDS (主从) └→ ElastiCache (Redis)
### CI/CD 流水线
```yaml

push:
branches: [main]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Build Docker
run: docker build -t app:${{ github.sha }} .
- name: Push to ECR
run: |
aws ecr get-login-password | docker login --username AWS --password-stdin $ECR_REGISTRY
docker push $ECR_REGISTRY/app:${{ github.sha }}
- name: Deploy to ECS
run: |
aws ecs update-service --cluster prod --service prod-app --force-new-deployment

```markdown
## 高可用架构设计
### 多区域部署
Region: us-east-1 (主) ↓ Route 53 (健康检查) ↓ ├→ Region: us-east-1 (主) │ ↓ │ ALB (多 AZ) │ ↓ │ ECS Cluster │ └→ Region: us-west-2 (灾备) ↓ ALB (多 AZ) ↓ ECS Cluster

|------|---------|--------|
| 单实例故障 | < 1min | 0 |
| 单区域故障 | < 5min | < 5min |

| 数据损坏 | < 30min | < 24h |
### 健康检查配置
```yaml
# ALB 健康检查
HealthCheck:
Interval: 30
Timeout: 5
UnhealthyThreshold: 2
HealthyThreshold: 2
Path: /health
// Route 53 健康检查配置
const healthCheck = {
Type: 'HTTPS',
FullyQualifiedDomainName: 'api.example.com',
Port: 443,
ResourcePath: '/health',
RequestInterval: 10,
FailureThreshold: 3,
};
### 4. 成本优化
分析和优化云资源成本。
**输出**:
```markdown
## 成本优化报告
### 当前成本分析
| 服务 | 当前费用 | 优化潜力 |
|------|---------|---------|
| EC2 | $200 | $100 (Reserved) |
| RDS | $150 | $75 (Reserved) |
| S3 | $50 | $20 (智能分层) |
| CloudFront | $100 | $80 (压缩) |
| Lambda | $50 | $40 (优化配置) |
### 优化建议
#### 1. 使用 Reserved 实例
- EC2: 1 年 Reserved → 节省 40%
- RDS: 1 年 Reserved → 节省 50%
#### 2. S3 智能分层
```typescript
// 创建智能分层配置
const bucket = new s3.Bucket(this, 'Storage', {
intelligentTieringConfigurations: [{
name: 'auto-tiering',
prefix: 'logs/',
fallbackStorageClass: 'GLACIER',
}],
});

development
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
devops
Create a new implementation plan file for new features, refactoring existing code or upgrading packages, design, architecture or infrastructure.
tools
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
documentation
Generates standardized porting documentation from completed feature changes. Analyzes commit diffs or file contents, extracts change intent, and outputs Markdown documentation for cross-team understanding. Should be used when the user needs to document a change for cross-team or cross-project consumption. Distinguished from cross-branch-fix-porter which actively re-implements fixes, this skill documents changes.
