# Prometheus

Prompt evolution without reference data.

## Quick Start

```bash
uv sync
uv run prometheus optimize -i examples/sample_config.yaml -o result.yaml -v
```

## Architecture

Clean hexagonal architecture with four layers:

- **Domain** — entities, ports, scoring (zero external dependencies)
- **Application** — use cases, bootstrap, evaluator, evolution loop
- **Infrastructure** — DSPy signatures, modules, adapters, file I/O
- **CLI** — Typer app with `optimize` command

## Testing

```bash
uv run pytest
uv run ruff check .
uv run mypy src/
```
