# promptfoo example — lead-qualification eval

A worked promptfoo eval: a HOT/WARM/COLD lead-classification prompt with three
assertion cases. Demonstrates the A11 prompt-testing workflow.

## Run

```bash
# from the repo root; ANTHROPIC_API_KEY must be set (PowerShell User scope)
npm run eval:llm
```

This makes **paid** Anthropic API calls. Run it manually or in CI only — never
in a git hook or pre-commit (A11 rule ML1). See `docs/ml/README.md`.

## Adapt

Copy `promptfooconfig.yaml` next to a real prompt when an AI feature is built.
Swap the model, add `tests`, use richer assertions (`contains`, `llm-rubric`,
cost/latency thresholds). Full reference: <https://promptfoo.dev/docs/>.
