## Installation

### Option 1: Claude Code Plugin Marketplace

Add the marketplace to Claude Code:

```bash
/plugin marketplace add zxkane/aws-skills
```

Install plugins individually:

```bash
# Install the common dependency first
/plugin install aws-common@aws-skills

# Then install the plugins you need
/plugin install aws-iac@aws-skills
/plugin install aws-cost-ops@aws-skills
/plugin install serverless-eda@aws-skills
/plugin install aws-agentic-ai@aws-skills
```

### Option 2: Install Individual Skills via npx

Install a single skill directly from the repository using [skills.sh](https://skills.sh):

```bash
# AWS CDK development skill
npx skills add https://github.com/zxkane/aws-skills --skill aws-cdk-development

# AWS SST (Ion) infrastructure-as-code skill
npx skills add https://github.com/zxkane/aws-skills --skill aws-sst-development

# AWS MCP setup (shared dependency)
npx skills add https://github.com/zxkane/aws-skills --skill aws-mcp-setup
```

Browse all skills at [skills.sh/zxkane/aws-skills](https://skills.sh/zxkane/aws-skills).

## Core CDK Principles

### Resource Naming

**Do NOT explicitly specify resource names** when they are optional in CDK constructs.

```typescript
// ✅ GOOD - Let CDK generate unique names
new lambda.Function(this, 'MyFunction', {
  // No functionName specified
});

// ❌ BAD - Prevents multiple deployments
new lambda.Function(this, 'MyFunction', {
  functionName: 'my-lambda',
});
```

### Lambda Functions

Use appropriate constructs for automatic bundling:

- **TypeScript/JavaScript**: `NodejsFunction` from `aws-cdk-lib/aws-lambda-nodejs`
- **Python**: `PythonFunction` from `@aws-cdk/aws-lambda-python-alpha`

### Pre-Deployment Validation

Before committing CDK code:

```bash
npm run build
npm test
npm run lint
cdk synth
./scripts/validate-stack.sh
```

## Usage Examples

### CDK Development

Ask Claude to help with CDK:

```
Create a CDK stack with a Lambda function that processes S3 events
```

Claude will:
- Follow CDK best practices
- Use NodejsFunction for automatic bundling
- Avoid explicit resource naming
- Grant proper IAM permissions
- Use MCP servers for latest AWS information

### Cost Optimization

Estimate costs before deployment:

```
Estimate the monthly cost of running 10 Lambda functions with 1M invocations each
```

Analyze current spending:

```
Show me my AWS costs for the last 30 days broken down by service
```

### Monitoring and Observability

Set up monitoring:

```
Create CloudWatch alarms for my Lambda functions to alert on errors and high duration
```

Investigate issues:

```
Show me CloudWatch logs for my API Gateway errors in the last hour
```

### Security and Audit

Audit activity:

```
Show me all IAM changes made in the last 7 days
```

Assess security:

```
Run a Well-Architected security assessment on my infrastructure
```

### Serverless Development

Build serverless applications:

```
Create a serverless API with Lambda and API Gateway for user management
```

Implement event-driven workflow:

```
Create an event-driven order processing system with EventBridge and Step Functions
```

Orchestrate complex workflows:

```
Implement a saga pattern for booking flights, hotels, and car rentals with compensation logic
```

### AI Agent Development

Deploy AI agents with Bedrock AgentCore:

```
Deploy a REST API as an MCP tool using AgentCore Gateway
```

Manage agent memory:

```
Set up conversation memory for my AI agent with DynamoDB backend
```

Monitor agent performance:

```
Configure observability for my AgentCore runtime with CloudWatch dashboards
```

## MCP Server Names

MCP server names use short identifiers to comply with Bedrock's 64-character tool name limit. The naming pattern is: `mcp__plugin_{plugin}_{server}__{tool}`

Examples: `awsdocs` (AWS docs), `cdk` (CDK), `cw` (CloudWatch), `sfn` (Step Functions), `sam` (Serverless), etc.
