Introducción

Add promptfoo-action to GitHub Actions to run prompt/agent evals on PRs or pushes, cache results, and comment a before/after report for safer iteration.

  • Best for: teams shipping prompts/agents who want CI regressions checks and a human-reviewable report in PRs
  • Works with: GitHub Actions, promptfoo configs (YAML/JSON), and optional caching via actions/cache (per repo docs)
  • Setup time: 13 minutes

Quantitative Notes

  • GitHub stars + forks (verified): see Source & Thanks
  • Action writes results to output.json (repo docs)
  • Setup time ~13 minutes (workflow + one config file)

Practical Notes

A minimal workflow is to run evals on PRs that touch prompts/** and store output.json as an artifact. Example snippet:

- uses: actions/checkout@v4
- uses: promptfoo/promptfoo-action@v1
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    config: promptfooconfig.yaml

Start with a small test set, then expand coverage once the report format fits your review process.

Safety note: Treat eval configs like code: review provider keys, red-team prompts, and data files; avoid leaking secrets in logs.

FAQ

Q: Do I need to host anything? A: No. It runs in GitHub Actions and uses promptfoo under the hood.

Q: Can I gate merges on quality? A: Yes. Use thresholds/fail options so CI fails when success rate drops.

Q: How do I keep costs down? A: Cache results and limit concurrency; run evals only on prompt-related paths.

🙏
