aws-aurora

aws-aurora is a skill for Claude Code from alinaqi/maggy. It costs 21 tokens per session (4,000 once invoked), scanned A, original, MIT.

A guide to Amazon Aurora, a managed relational database compatible with MySQL and PostgreSQL. It focuses on serverless scaling and ways to manage database connections from services such as AWS Lambda.

In plain words
What is it for?
It is for choosing Aurora Serverless or provisioned deployments, connecting Lambda functions, using RDS Proxy or Data API, and planning high-availability or multi-region setups.
Why use it?
It helps avoid too many database connections and unreliable serverless applications. It explains when to use connection pooling through RDS Proxy or the HTTP-based Data API.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aws-aurora scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

AWS Aurora Skill

Amazon Aurora is a MySQL/PostgreSQL-compatible relational database with serverless scaling, high availability, and enterprise features.

Sources: Aurora Docs | Serverless v2 | RDS Proxy


Core Principle

Use RDS Proxy for serverless, Data API for simplicity, connection pooling always.

Aurora excels at ACID-compliant workloads. For serverless architectures (Lambda), always use RDS Proxy or Data API to handle connection management. Never open raw connections from Lambda functions.


Aurora Options

Option Best For
Aurora Serverless v2 Variable workloads, auto-scaling (0.5-128 ACUs)
Aurora Provisioned Predictable workloads, maximum performance
Aurora Global Multi-region, disaster recovery
Data API Serverless without VPC, simple HTTP access
RDS Proxy Connection pooling for Lambda, high concurrency

Connection Strategies

Strategy 1: RDS Proxy (Recommended for Lambda)

Lambda → RDS Proxy → Aurora
         (pool)
  • Connection pooling and reuse
  • Automatic failover handling
  • IAM authentication support
  • Works with existing SQL clients

Strategy 2: Data API (Simplest for Serverless)

Lambda → Data API (HTTP) → Aurora
  • No VPC required
  • No connection management
  • Higher latency per query
  • Limited to Aurora Serverless

Strategy 3: Direct Connection (Not for Lambda)

App Server → Aurora
(persistent connection)
  • Only for long-running servers (ECS, EC2)
  • Manage connection pool yourself
  • Not suitable for serverless

RDS Proxy Setup

Create Proxy (AWS Console/CDK)

// CDK example
import * as rds from 'aws-cdk-lib/aws-rds';

const proxy = new rds.DatabaseProxy(this, 'Proxy', {
  proxyTarget: rds.ProxyTarget.fromCluster(cluster),
  secrets: [cluster.secret!],
  vpc,
  securityGroups: [proxySecurityGroup],
  requireTLS: true,
  idleClientTimeout: cdk.Duration.minutes(30),
  maxConnectionsPercent: 90,
  maxIdleConnectionsPercent: 10,
  borrowTimeout: cdk.Duration.seconds(30)
});

aws-aurora is a skill published in the GitHub repository alinaqi/maggy (707 stars, last pushed 3d ago), licensed MIT. It adds 21 tokens to every session and 4,000 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
