github-action (GitHub Action)

You can run this example with:

npx promptfoo@latest init --example github-action

This folder contains a standalone GitHub Action that runs promptfoo when a pull request modifies prompts.

Prerequisites

• GitHub repository with Actions enabled
• API keys for LLM providers set as repository secrets:
  • OPENAI_API_KEY - Get from OpenAI API keys page
  • ANTHROPIC_API_KEY - Get from Anthropic Console (optional)

Setting up GitHub Secrets:

1. Go to your repository → Settings → Secrets and variables → Actions
2. Click "New repository secret"
3. Add OPENAI_API_KEY with your OpenAI API key as the value
4. Repeat for other provider keys as needed

Usage

Edit standalone-action.yaml as needed and add it to your repository's .github/workflows/ directory. The action will automatically run when pull requests modify prompt files.

Expected Results

When triggered, the action will:

• Install promptfoo in the GitHub runner environment
• Run evaluations on the modified prompts
• Post results as PR comments or check results
• Fail the check if evaluations don't meet configured thresholds
