platisd/openai-pr-description GitHub Action

Autofill the description of your pull requests with the power of OpenAI!

What does it do?

chalermporn17/openai-pr-description is forked from

`platisd/openai-pr-description` which is a GitHub Action that looks at the title as well as the contents
of your pull request and uses the [OpenAI API](https://openai.com/blog/openai-api) to automatically
fill up the description of your pull request. Just like ChatGPT would! 🎉<br>
The Action tries to focus on **why** the changes are needed rather on **what** they are,
like any proper pull request description should.

The GitHub Action will only run when a PR description is not already provided.
In other words it will not accidentally overwrite your existing description.
The idea is this Action will save you the time and trouble of writing **meaningful** pull request descriptions.<br>
You can customize it in different ways. One of them allows the Action to only run on pull requests started
by specific users, e.g. the main maintainers of the repository.
Keep in mind the OpenAI API is not free to use. That being said, so far it's been rather cheap,
i.e. around ~$0.10 for 15-20 pull requests so far.

New Feature

• model selection base on change which will choose bigger model if pull request if big.
• terminated if there aren't any avialable model for pull request if pull request if too big.
• specific file type. so some trash file doesn't included.

How can you use it?

1. Create an account on OpenAI, set up a payment method and get your OpenAI API key.
2. Add the OpenAI API key as a secret in your repository's settings.
3. Create a workflow YAML file, e.g. .github/workflows/openai-pr-description.yml with the following contents:

• GOOD_SAMPLE_RESPONSE

  This pull request aims to integrate Valgrind into our Continuous Integration (CI) process to enhance memory leak detection and code reliability.
  
  ## Changes Made
      - **CI Workflow Update**: Included Valgrind installation and configured it to run with our test suite.
      - **Test Suite Adjustments**: Made minor adjustments to the test suite for better compatibility with Valgrind and improved test coverage.
  
  ## Impact
      - **Enhanced Code Quality**: Integrating Valgrind allows for automatic detection of memory leaks and access errors, leading to a more robust codebase.
      - **Improved Testing**: The adjustments in the test suite ensure comprehensive testing and accuracy.
  

Model Selection Process

1. Calculate the total number of tokens used in the model prompt (prompt_tokens), which includes the tokens from the example prompt, example response, and the prompt generated from the pull request.

2. Select an appropriate model based on the following criteria:

   • Ensure that the model's maximum token capacity (model_max_token) is greater than the sum of prompt_tokens and max_response_tokens.
   • If multiple models satisfy this condition, select the one with the smallest maximum token capacity.

403 error when updating the PR description

If you get a 403 error when trying to update the PR description, it's most likely because the GitHub Action is not allowed to do so. The easiest way forward is to grant the necessary permissions to the GITHUB_TOKEN secret at <your_repo_url>/settings/actions under Workflow permissions.
