## What it does

The `dsql` skill teaches an agent how to work with Aurora DSQL, a serverless distributed SQL database that speaks PostgreSQL. It ships as a set of reference files loaded on demand: DDL rules and transaction limits, driver selection and connection code, scoped role setup with IAM-to-database role mapping, and fixes for OCC errors and expired tokens.

Migrations get their own sections. You get type and DDL conversion from MySQL and PostgreSQL, foreign key replacement with generated code, OCC retry patterns, ORM migration for Django, Hibernate and Rails, and batched migration for tables over 3,000 rows. Bulk loading goes through `aurora-dsql-loader`.

Load `references/dsql-lint.md` before running `dsql_lint` or processing external SQL, otherwise the fix statuses and unfixable errors make no sense. Some operations run through MCP tools, so those need configuring first.

## Requirements
- Works with: PostgreSQL

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill dsql -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill dsql -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill dsql -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cline/skills dsql
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill dsql -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cline/skills --path skills/dsql
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill 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/cline/skills/tree/HEAD/skills/dsql/SKILL.md

## When to use it
- convert a MySQL or PostgreSQL schema to Aurora DSQL types
- replace foreign keys and generate application-layer checks
- read a query plan with EXPLAIN ANALYZE
- add retry logic for OCC conflicts
- bulk load CSV files into DSQL

## Example prompts
- Convert this MySQL table to Aurora DSQL: types, ENUM and foreign keys
- Why does my DSQL query fail with an OCC error, and how do I add retries?
- Load this CSV into DSQL with aurora-dsql-loader
