  • Prepare a repo that you want apply for PR Agent, we are using https://github.com/gyliu513/langx101
  • Generate a Personal access tokens for you GitHub Account. You can set this via Settings -> Developer Settings -> Personal access tokens

  • Add the following secret to your repository under Settings > Secrets and variables > Actions > New repository secret > Add secret. In my example, I was using OPENAI_KEY as the secret name. w

  • Add the following file to your repository under .github/workflows/pr_agent.yml:
on:
  pull_request:
    types: [opened, reopened, ready_for_review]
  issue_comment:
jobs:
  pr_agent_job:
    if: $
    runs-on: ubuntu-latest
    permissions:
      issues: write
      pull-requests: write
      contents: write
    name: Run pr agent on every pull request, respond to user comments
    steps:
      - name: PR Agent action step
        id: pragent
        uses: Codium-ai/pr-agent@main
        env:
          OPENAI_KEY: $
          GITHUB_TOKEN: $

You can also refer to Run as a GitHub Action to get more detail for how to config.

You are all set. If you create a PR for your repo, you will see a bot named as github-actions is helping to generate the descrption of the PR and also helping you review your PRs with suggestions.
