# Stackchain Library

A minimal Python library for composing ordered CLI toolchains from YAML.

## Install

```
pip install stackchain
```

## Usage

```yaml
# chain.yaml
steps:
  - run: lint
  - run: test
  - run: build
```

```bash
stackchain run chain.yaml
```

## Config

- `--fail-fast` stops on first non-zero exit (default: false).
- `--dry-run` prints steps without executing.
