Authors and runs Promptfoo evals for LLM prompts and RAG pipelines - wires `promptfooconfig.yaml` providers + prompts + tests + assertions (deterministic `equals` / `contains` / `is-json` / `regex`, semantic `similar`, model-graded `llm-rubric` / `factuality` / `g-eval`, performance `latency` / `cost`, custom `javascript` / `python`), runs `npx promptfoo eval`, views HTML report via `promptfoo view`, and integrates CI for regression gating. Use when the user runs Promptfoo, asks about prompt…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# promptfoo-evaluation

[pf-intro]: https://promptfoo.dev/docs/intro/
[pf-config]: https://promptfoo.dev/docs/configuration/guide/

A `promptfooconfig.yaml` declares **providers** (LLMs under test),
**prompts** (templates with `{{var}}` placeholders), **tests**
(input variables + assertions); `promptfoo eval` runs the
cross-product (per [pf-config][pf-config]).

## When to use

- The repo has a `promptfooconfig.yaml` or the user wants to
  author one.
- The user needs prompt regression suites - same inputs, multiple
  providers, fail-on-diff.
- A CI workflow needs an eval gate on prompt or model changes.
- The team prefers vendor-neutral eval (vs OpenAI Evals' OpenAI-first
  posture).

## Step 1 - Install

Per [github.com/promptfoo/promptfoo][pf-gh]:

[pf-gh]: https://github.com/promptfoo/promptfoo

```bash
npm install -g promptfoo
# or
brew install promptfoo
# or one-off
npx promptfoo@latest
```

Per [pf-gh][pf-gh]: "Node.js 20.20+ or 22.22+ is required for npm
and npx usage."

## Step 2 - First eval

Initialize from a built-in example, then run:

```bash
promptfoo init --example getting-started
cd getting-started
promptfoo eval
promptfoo view  # opens HTML report
```
…

How to install

The exact contents, by fingerprint
mdr add testland/qa/promptfoo-evaluation@sha256:946f34b1750c018a

The line at the top of this page pins the label git:20260724.d4db756, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
