Rules for AI coding assistants working in this repository.

- **dora >= 1.0.** Verified against `dora-cli 1.0.1`, which CI pins in
  `.github/workflows/validate.yml`.
- **`uv` for everything:** `uv sync --group dev`, `uv run pytest`,
  `uv run ruff check .`, `uv run python ...`. Never `pip` into the ambient
  environment. A node's `build:` is `uv pip install .`, so dataflows must be run
  with `--uv`.
- **`ruff` is the linter and the formatter.** `uv run ruff check .` must be clean.
- **Markdown is linted too.** `uv run pymarkdown scan -r --respect-gitignore .` must be clean. Its line
  length is set in `pyproject.toml`.
- **numpy-style docstrings.**
- **Dependencies must ship prebuilt wheels for linux-x86_64, linux-aarch64 and
  macos-arm64.** `uv sync` is the whole install: no system packages, no compiler.
- **Run the workflow locally with `act` before asking for a commit:**

  ```bash
  act pull_request -P ubuntu-latest=catthehacker/ubuntu:act-latest
  ```

  Workflows live in `.github/workflows/`, not `.gitea/workflows/`, so that `act`
  finds them with no `-W`. Gitea Actions reads both locations; keep only this one,
  or a run fires twice.

- **Do not commit or push.** Leave changes in the working tree and wait to be asked.
- **Do not mention AI tools in commit messages or documentation.**
