## What it does

This skill guides coding agents through Amazon Aurora DSQL database workflows. It provides patterns for cluster management, query execution via `psql` using `scripts/psql-connect.sh`, and schema updates. For application backends, it specifies canonical DSQL Connectors across Python, Go, Java, and JavaScript instead of direct unmanaged drivers.

Aurora DSQL enforces strict constraints: one DDL statement per transaction and asynchronous indexes. The skill explicitly rejects query concatenation via f-strings and requires parameterized queries with `tenant_id` validation. IAM auth tokens expire after 15 minutes, which makes driver-level token rotation mandatory for any long-running connection pool.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill aurora-dsql -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/aurora-dsql/SKILL.md

## When to use it
- connect to Aurora DSQL using IAM authentication tokens
- migrate database schemas from MySQL to Aurora DSQL
- diagnose slow queries with EXPLAIN ANALYZE
- isolate customer records using tenant_id parameterization

## Example prompts
- Write a Python connection script for Aurora DSQL using IAM token rotation
- Review this DDL script against Aurora DSQL single-statement rules
- Generate a parameterized query with safe tenant_id handling

# Amazon Aurora DSQL

## Overview

Aurora DSQL is a serverless, PostgreSQL-compatible distributed SQL database. This skill provides direct database interaction via `psql` scripts and PostgreSQL drivers, schema management, migration support, multi-tenant patterns, and query-plan explainability.

**Key capabilities:**

- Direct query execution via `psql` with generated IAM auth tokens (see [`scripts/psql-connect.sh`](scripts/psql-connect.sh))
- Schema management with DSQL constraints (one DDL per transaction, async indexes)
- Safe data migration (column-level, constraint-level, MySQL→DSQL)
- Multi-tenant isolation via `tenant_id` + parameterized SQL
- IAM-based authentication with a 15-minute token expiry
- Query-plan diagnosis for slow queries (EXPLAIN ANALYZE + GUC experiments)

The recommended runtime is `psql` with `aws dsql generate-db-connect-auth-token` for IAM-authenticated sessions. Application code SHOULD use the language-specific [DSQL Connectors and SDKs](https://docs.aws.amazon.com/aurora-dsql/latest/userguide/aws-sdks.html). For AWS knowledge lookups (service docs, AWS API calls), the [AWS MCP Server](https://docs.aws.amazon.com/aws-mcp/latest/userguide/mcp-server.html) is the preferred MCP integration.

## Reference Files

Load these files as needed for detailed guidance:

### [development-guide.md](references/development-guide.md)

**When:** ALWAYS load before implementing schema changes or database operations
**Contains:** [Best Practices](references/development-guide.md), DDL rules, connection patterns, transaction limits, data type serialization patterns, application-layer referential integrity instructions, security best practices

### Query Execution:

#### [database-tools.md](references/database-tools.md)

**When:** Load when you need detailed syntax and examples for ad-hoc query execution against DSQL. PREFER `psql` (via [`scripts/psql-connect.sh`](scripts/psql-connect.sh)) for ad-hoc queries — execute directly rather than writing one-off scripts.
**Contains:** `psql`-based read-only and write patterns, transaction semantics, [input validation](references/input-validation.md)
