# AGENTS.md

Apache Airflow - A platform to programmatically author, schedule, and monitor workflows

## Setup

```
uv sync
```

## Commands

```
pytest         # run the test suite
ruff check .   # lint
```

## Layout

- `providers/`    5474 source files
- `airflow-core/` 2072 source files
- `scripts/`      320 source files
- `task-sdk/`     254 source files
- `dev/`          235 source files
- `devel-common/` 105 source files

## Conventions

- Tests live alongside the code they cover, following `airflow-core/src/airflow/api_fastapi/auth/managers/simple/ui/src/login/Login.test.tsx`.
- CI defines what passing means. See `.github/workflows/additional-ci-image-checks.yml`, and keep it green.
- TODO: add the two or three conventions a newcomer always gets wrong here.

## Gotchas

- `airflow-core/tests/unit/jobs/test_scheduler_job.py` is 568KB. It will not fit comfortably in context, so read it in parts.
