## What it does

The skill covers the whole pipeline: extraction from Postgres, MySQL, MongoDB, REST APIs and CSV/JSON files, a transformation layer, and loading into BigQuery, Snowflake, Redshift or a data lake. It ships YAML config schemas, Python and SQL transformation examples, aggregation rules and join operations.

Orchestration is defined as a DAG: schedule, task dependencies, extract/transform/load steps and a Slack notification. Failures are handled by an error_handling block with retries, exponential backoff and a dead letter queue in S3. A separate section covers data quality checks such as not_null and value ranges, each with a severity level.

Source access runs through the `data-mcp` MCP server with the `postgres_query`, `mysql_query`, `mongodb_aggregate`, `bigquery_load` and `snowflake_api` tools. Without that server the skill cannot reach your databases directly, so check your MCP setup before wiring anything up. The example configs use placeholders like `${execution_date}` and `${start_date}` — swap them for your own tables.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill etl-pipeline -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill etl-pipeline -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill etl-pipeline -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install claude-office-skills/skills etl-pipeline
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill etl-pipeline -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/claude-office-skills/skills --path etl-pipeline
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill etl-pipeline -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/claude-office-skills/skills/tree/HEAD/etl-pipeline/SKILL.md

## When to use it
- build a daily pipeline from Postgres into BigQuery
- set up incremental extraction keyed on updated_at
- clean and deduplicate records before loading
- define a DAG with dependencies between tasks
- add data quality checks and alerts on failure

## Example prompts
- Design an ETL pipeline that pulls orders from Postgres, cleans them and loads into BigQuery once a day
- Set up incremental extraction from MySQL on updated_at and a dead letter queue for failed records
- Add a not_null check for customer_id and an amount range starting at 0 to the pipeline
