## What it does

The skill handles Amazon RDS management across MySQL, MariaDB, and PostgreSQL engines. When provisioning new databases, it automatically applies production defaults: Multi-AZ failover, `gp3` storage, deletion protection, Secrets Manager passwords, and customer-managed KMS encryption.

It also assists with upgrade paths by checking valid targets via `describe-db-engine-versions`. For schema changes and major version jumps, it prepares Blue/Green deployment plans with replication checks. The skill can trigger instance creation directly, but operations like version upgrades and commitment purchases remain strictly advisory.

You need the AWS CLI or an AWS MCP server to run commands. The skill does not support Amazon Aurora clusters, which require the separate `amazon-aurora` tool.

## Requirements
- Works with: AWS, PostgreSQL

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oss -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/rds-oss/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/rds-oss/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oss -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/rds-oss/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oss -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/rds-oss/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws rds-oss
```

2. **Manually: put the files in place**
- File: `.github/skills/rds-oss/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oss -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/specialized-skills/database-skills/rds-oss
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/rds-oss/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oss -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aws/agent-toolkit-for-aws/tree/HEAD/skills/specialized-skills/database-skills/rds-oss/SKILL.md

## When to use it
- Provision production-ready RDS MySQL or PostgreSQL instances with security defaults
- Map database upgrade paths and generate pre-upgrade checklists
- Compare Reserved Instance and Database Savings Plan commitments
- Plan low-downtime Blue/Green deployments for production schema updates

## Example prompts
- Create a production-ready RDS PostgreSQL database using the latest stable engine
- Plan an upgrade for RDS MariaDB 10.6 to the latest release with live prechecks
- Evaluate whether to use Reserved Instances or a Database Savings Plan for my db.r7g.2xlarge RDS MySQL instance

description: Advises on Amazon RDS open-source engines (MySQL, MariaDB, PostgreSQL) for instance creation, upgrade planning, commitment pricing, proxy evaluation, and Blue/Green deployments. Handles any RDS MySQL, MariaDB, or PostgreSQL question, including create a production-ready RDS MySQL instance, provision an RDS PostgreSQL database, run the RDS upgrade advisor for my RDS MySQL instance, what are my upgrade options, upgrade RDS MariaDB from 10.6 to the latest version, should I buy reserved instances or a savings plan for db.r7g.2xlarge RDS MySQL, change a VARCHAR to INT column on RDS MySQL 8.0 with Blue/Green, and does RDS Proxy help when PgBouncer already runs in transaction mode. Covers instance creation with production best practices, describe-db-instances and describe-db-engine-versions upgrade-target workflow, live prechecks via SSM or direct connection, RI versus DSP commitment pricing, RDS Proxy versus PgBouncer, and Blue/Green lifecycle with binlog replay compatibility.

# RDS OSS Advisor (MySQL, MariaDB, PostgreSQL)

## Overview

Advisor for Amazon RDS on the open-source engines — **MySQL**, **MariaDB**, and **PostgreSQL**. Five decision areas:

1. **Instance creation** — provision production-ready instances with best-practice defaults (latest version, Multi-AZ, encryption, Performance Insights, Secrets Manager password management)
2. **Upgrade planning** — identify instance, enumerate targets, run live prechecks, flag plan regressions, surface pre/post checklists
3. **Commitment pricing** — estimate RI and Database Savings Plan savings for steady workloads
4. **RDS Proxy evaluation** — decide whether proxy is worth it, based on connection utilization and pinning risks
5. **Blue/Green deployments** — plan low-downtime DDL or major upgrades, with DDL compatibility analysis

Produces cost estimates, precheck findings, and CLI commands. For instance creation, executes the create-db-instance call with production best practices. For upgrades, purchases, and switchovers — advisory only, never executes without explicit user confirmation.

Scoped to RDS open-source engines. For Aurora, use `amazon-aurora`. For Oracle, SQL Server, Db2, use the engine-specific skills.

The AWS MCP server is recommended for executing commands but is not required; all operations can also be performed via the AWS CLI.

## Decision Guide

| User asks about… | Go to |
|---|---|
| Create, provision, or set up a new RDS MySQL/MariaDB/PostgreSQL instance | [Production Instance Creation](#production-instance-creation) below |
| Upgrade, target version, pre/post-upgrade checklist, upgrade prechecks, Read Replica upgrade order | [references/upgrade-workflow.md](references/upgrade-workflow.md) |
