## What it does

The skill kicks in when you ask the agent to scaffold a new Airflow project or make sense of an existing one. It knows `astro dev init` and explains what the command produces: `dags/`, `include/`, `plugins/`, `tests/`, `Dockerfile`, `packages.txt`, `requirements.txt` and `airflow_settings.yaml`.

Dependencies go into `requirements.txt` for Python packages and `packages.txt` for OS-level ones. For a private index or custom scripts, the skill edits the `Dockerfile` on top of the Astro Runtime image. After any change it reminds you to run `astro dev restart`. Connections, variables and pools live in `airflow_settings.yaml` and load when the environment starts; you can also move them with `astro dev object export` and `astro dev object import`.

To catch DAG errors without booting the whole environment, run `astro dev parse`. The skill advises against passing `--airflow-version` or `--runtime-version` unless you need a specific pin: plain `astro dev init` picks the current Astro Runtime, while a version recalled from model memory may be stale. If you are not on Astro, it points you to the Apache Airflow Docker Compose quickstart for local dev and the Helm chart for production.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add astronomer/agents --skill setting-up-astro-project -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add astronomer/agents --skill setting-up-astro-project -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add astronomer/agents --skill setting-up-astro-project -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install astronomer/agents setting-up-astro-project
```

2. **Manually: put the files in place**
- File: `.github/skills/setting-up-astro-project/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add astronomer/agents --skill setting-up-astro-project -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/astronomer/agents --path skills/setting-up-astro-project
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add astronomer/agents --skill setting-up-astro-project -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/astronomer/agents/tree/HEAD/skills/setting-up-astro-project/SKILL.md

## When to use it
- scaffold a new Airflow project with the Astro CLI
- add Python and OS-level dependencies to a project
- declare connections, variables and pools in one file
- move environment settings between machines
- check DAGs for errors before starting the environment

## Example prompts
- create a new Airflow project with astro dev init and show me the folder structure
- add the Snowflake provider and pandas to requirements.txt, then restart the environment
- set up the my_postgres connection and the env variable in airflow_settings.yaml

# Astro Project Setup

This skill helps you initialize and configure Airflow projects using the Astro CLI.

> **To run the local environment**, see the **managing-astro-local-env** skill.
> **To write DAGs**, see the **authoring-dags** skill.
> **Open-source alternative:** If the user isn't on Astro, guide them to Apache Airflow's Docker Compose quickstart for local dev and the Helm chart for production. For deployment strategies, use the `deploying-airflow` skill.

---

## Initialize a New Project

```bash
astro dev init
```

> **Don't pass `--airflow-version` or `--runtime-version` unless the user explicitly asks for a specific pin.** Plain `astro dev init` resolves to the latest Astro Runtime — that's the right default. Specifying a version risks pinning to a stale value from training data. If the user wants to know what was installed, read the generated `Dockerfile` afterward instead of guessing.

Creates this structure:
```

├── requirements.txt     # Python packages
└── airflow_settings.yaml # Connections, variables, pools
```

## Adding Dependencies

### Python Packages (requirements.txt)

```
apache-airflow-providers-snowflake==5.3.0
pandas==2.1.0
requests>=2.28.0
```

### OS Packages (packages.txt)

```
gcc
libpq-dev
```

### Custom Dockerfile

For complex setups (private PyPI, custom scripts):

```dockerfile
FROM quay.io/astronomer/astro-runtime:12.4.0

RUN pip install --extra-index-url https://pypi.example.com/simple my-package
```

**After modifying dependencies:** Run `astro dev restart`

---

## Configuring Connections & Variables

### airflow_settings.yaml

Loaded automatically on environment start:

```yaml
airflow:
  connections:
    - conn_id: my_postgres
      conn_type: postgres
````
