The gpt-commit-summarizer GitHub Action is a powerful tool that harnesses the capabilities of OpenAI's state-of-the-art text-davinci-003 large language model to provide summaries of the changes introduced by a pull request in a repository. By generating the git diff for each commit and for each modified file and sending it to the OpenAI API with a carefully crafted prompt, the action is able to produce concise and informative summaries that can greatly enhance collaboration and understanding in large codebases.

The action then performs a higher level call to the OpenAI API to generate a summary of the entire pull request, from the summaries of individual commits and file differences. This summary is then posted as a comment on the pull request.

Getting Started

Automatic Setup

Works for all git repositories. follow the CLI instructions:

npx add-gpt-summarizer@latest

Note: Requires that you have Node.js installed.

Setting up

To use this action, you will need to have an OpenAI API key. If you don't already have one, you can sign up for an OpenAI API key here.

Once you have your API key, you will need to add it to your GitHub repository as a secret. To do this, go to your repository's settings and navigate to the "Secrets" section. Click on "Add a new secret" and enter the secret name OPENAI_API_KEY and the value of your API key.

Next, you will need to add the workflow file to your repository. Create a file named .github/workflows/gpt-commit-summarizer.yml (relative to the git root folder) and copy the following code into it:

name: GPT Commits summarizer
# Summary: This action will write a comment about every commit in a pull request, as well as generate a summary for every file that was modified and add it to the review page, compile a PR summary from all commit summaries and file diff summaries, and delete outdated code review comments

on:
  pull_request:
    types: [opened, synchronize]

jobs:
  summarize:
    runs-on: ubuntu-latest
    permissions: write-all  # Some repositories need this line

    steps:
      - uses: KanHarI/gpt-commit-summarizer@master
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}

This workflow file tells GitHub to run the action whenever a new pull request is opened or updated.

That's it! You're now ready to use the gpt-commit-summarizer action in your repository. Each time a pull request is opened or updated, the action will automatically generate a summary of the changes made in each commit, add a summary for every file that was modified to the review page, compile a PR summary from all commit summaries and file diff summaries, and delete outdated code review comments.

Troubleshooting

I have heard some unverified reports that the OpenAI API may block requests from the IP addresses of some runners. If you encounter this issue, you can try using a self-hosted runner to run the gpt-commit-summarizer action. This can be done by setting up a runner on a server that you control, and then adding the runner to your repository.

To set up a self-hosted runner, you will need to follow these steps:

• Install the GitHub Actions Runner on your server. Follow the instructions in the documentation to do this.

• Add the self-hosted runner to your repository. Follow the instructions in the documentation to do this.

• Modify the workflow file to use the self-hosted runner. Open the .github/workflows/gpt-commit-summarizer.yml file and add the runs-on field to specify the self-hosted runner that you want to use. For example:

name: GPT Commits summarizer
# Summary: This action will write a comment about every commit in a pull request, as well as generate a summary for every file that was modified and add it to the review page, compile a PR summary from all commit summaries and file diff summaries, and delete outdated code review comments

on:
  pull_request:
    types: [opened, synchronize]

jobs:
  summarize:
    runs-on: self-hosted
    permissions: write-all  # Some repositories need this line

    steps:
      - uses: KanHarI/gpt-commit-summarizer@master
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}
