Change PR Description GitHub Action

This action is designed to automatically update or modify the description of a pull request. It uses OpenAI's GPT model to generate the description content based on the pull request content or a given template. This is especially useful when you want to maintain a standardized format across all pull request descriptions in a repository.

Inputs

The action takes several inputs:

github-token: Your GitHub token. This is required to interact with the GitHub API and is always required.
pr-number: The number of the pull request that the description should be updated for. This is also always required.
openai-token: Your OpenAI token. This is used to generate the description using OpenAI's models and is always required. Make sure to store this token as a GitHub secret and pass it as an input to your workflow.
pull-request-template: An optional path to a template file that should be used for generating the PR description. If not provided, the description will be generated based on the PR's content.
trigger-word: An optional trigger word that will trigger the action when found in the PR's description. If not provided, the default is "auto", which means the action will run automatically whenever a PR is opened.
openai-model: An optional parameter to specify the OpenAI model to be used for generating the PR description. If not provided, the default model is gpt-3.5-turbo-16k.
skip-if-author-is: An optional parameter to specify a list of authors (comma separated) for which the action should not run. By default, this is empty, meaning the action will run for all authors.

Usage

To use this action, you should add it to your GitHub workflow. Here is an example workflow that uses this action:

name: Draft PR Description
on:
  pull_request:
    types: [opened]

jobs:
  change-description:
    runs-on: ubuntu-latest
    steps:
      - name: Add Draft PR description
        uses: kieranklaassen/gpt-auto-pr-description-action@main
        with:
          github-token: ${{ secrets.GITHUB_TOKEN }}
          pr-number: ${{ github.event.pull_request.number }}
          openai-token: ${{ secrets.OPENAI_TOKEN }}

In this example, the action is triggered whenever a pull request is opened. It uses the github-token, pr-number, and openai-token inputs to interact with the GitHub API and generate the PR description. The OpenAI token is stored as a secret to keep it secure.

Dependencies

This action depends on:

Ruby and the ruby/setup-ruby action to set up a Ruby environment.
The actions/checkout action to check out the repository.
Your OpenAI token to access the OpenAI API. Make sure to store this token as a GitHub secret and pass it as an input to your workflow.
