git-bob 0.9.1

An AI-based assistant for handling github issues and pull-requests

git-bob

git-bob uses AI to solve GitHub issues and review pull requests. It runs inside the GitHub CI, no need to install anything on your computer. Read more in the preprint.

Under the hood it uses Anthropic's Claude or OpenAI's chatGPT or Google's Gemini to understand the text and pygithub to interact with the issues and pull requests.

Disclaimer

git-bob is a research project aiming at streamlining GitHub interaction in software development projects. Under the hood it uses artificial intelligence / large language models to generate text and code fulfilling the user's requests. Users are responsible to verify the generated code according to good scientific practice.

When using git-bob you configure it to use an API key to access the AI models. You have to pay for the usage and must be careful in using the software. Do not use this technology if you are not aware of the costs and consequences.

[!CAUTION] When using the Anthropic, OpenAI, Google Gemini or any other endpoint via git-bob, you are bound to the terms of service of the respective companies or organizations. The GitHub issues, pull requests and messages you enter are transferred to their servers and may be processed and stored there. Make sure to not submit any sensitive, confidential or personal data. Also using these services may cost money.

Installation as GitHub action

There is a detailed tutorial on how to install git-bob as GitHub action to your repository. In very short, to use git-bob in your GitHub repository, you need to

• Copy the git-bob GitHub workflow in folder .github/workflows/ to your repository.
  • Make sure to replace pip install -e . with a specific git-bob version such as pip install git-bob==0.4.0.
  • Configure the LLM you want to use in the workflow files by specifying the GIT_BOB_LLM_NAME environment variable. These were tested:
• claude-3-5-sonnet-20240620
• gpt-4o-2024-08-06 (recommended if you work with large files, < 16k tokens)
• github_models:gpt-4o
• github_models:meta-llama-3.1-405b-instruct
• gemini-1.5-pro-002
• configure a GitHub secret called OPENAI_API_KEY or ANTHROPIC_API_KEY or GH_MODELS_API_KEY or GOOGLE_API_KEY or KISSKI_API_KEY or BLABBLADOR_API_KEY with the corresponding key from the LLM provider depending on the above configured LLM. You can get these keys here:
  • OpenAI (gpt)
  • Anthropic (claude)
  • GitHub Models Marketplace
  • Google AI
  • KISSKI
  • BLABLADOR
• configure GitHub actions to run the workflow on issues and pull requests. Also give write-access to the Workflow using the GITHUB_TOKEN.

When using it in your repository, you can also set a custom system message, for example for:

• General Data Science / Python Programming
• Bio-Image Analysis
• Giving advice on a specific repository / library
• Manuscript writing

Furthermore, to guide discussions, you may want to setup issue templates, e.g.

• General Python Programming Questions
• Bio-Image Analysis
• Statistics and Plotting

Usage

To trigger git-bob, you need to comment on an issue or pull request with the following command:

git-bob comment

If the issue is complex and should be split into sub-issues, you can use the following command:

git-bob split

You can ask git-bob to implement a solution, e.g. as Jupyter notebook and run it like this:

git-bob try

You can also use the following command to trigger git-bob solving an issue. It will then try to solve the issue and send a pull request. This action can also be used to modify code in pull requests.

git-bob solve

If you have multiple API-Key for different LLMs configured, you can specify the LLM in the command, e.g.:

git-bob ask claude-3-5-sonnet-20240620 to solve this issue.

If you have two GitHub secrets TWINE_USERNAME and TWINE_PASSWORD configured, you can also use the following command to publish a new version of your library to PyPI:

git-bob deploy

Recommended Workflow

Here's the recommended workflow for using git-bob:

1. Create an issue describing the problem or task.
2. Comment on the issue with git-bob comment, or git-bob think about this (an alias for comment) to trigger git-bob making a plan.
3. Respond to git-bob with any clarifications or additional information it requests.
4. Comment on the issue with git-bob solve or git-bob implement this (an alias for solve) to trigger git-bob.
5. Wait for git-bob to create a pull request (PR) addressing the issue.
6. Review the PR and comment on the PR or on the original issue if changes are needed.
7. Wait for git-bob to create new PR or modifying the existing PR with the requested changes.
8. Repeat steps 3-5 as necessary until the issue is resolved satisfactorily.

Use-case examples

• Bio-image Analysis Support
• Question-answering to specific Python libraries
• Basic data analysis and plotting
• Documenting source code
• Assisting scientific manuscript writing

Installation for development

git clone https://github.com/haselinhuepf/git-bob.git
cd git-bob

Usage as command-line tool (for development)

You can also install git-bob locally and run it from the terminal. In this case, create a GitHub token and store it in an environment variable named GITHUB_API_KEY. Also create an environment variable GIT_BOB_LLM_NAME with the name of the LLM you want to use, e.g. "gpt-4o-2024-05-13" or "claude-3-5-sonnet-20240620" or "github_models:gpt-4o". Then you can install git-bob using pip:

pip install git-bob

Usage as command-line tool (for development)

You can then use git-bob from the terminal on repositories you have read/write access to. It is recommended to call it from the root folder of the repository you want to interact with.

git clone https://github.com/<organization>/<repository>
cd <repository>
git-bob <action> <organization>/<repository> <issue-number>

Available actions:

• review-pull-request
• comment-on-issue
• solve-issue
• split-issue

Limitations

git-bob is a research project and has limitations. It serves as basis for discussion and further development. Once LLMs become better, git-bob will become better as well.

At the moment, these limitations can be observed:

• git-bob was tested for Python projects mostly. It seems to be able to process Java and C++ as well.
• It can only execute code in Jupyter Notebooks.
• It sometimes hallucinates, especially in code reviews. E.g. it claimed to have tested code, which is certainly not true.
• It cannot solve issues where changing long files is required, as the output of the LLMs is limited by a maximum number of tokens (e.g. 16k for gpt-4o-2024-08-06). When using OpenAI's models it combines output of multiple requests to a maximum file length about 64k tokens. It may then miss some spaces or a line break where responses were stitched. When using GitHub models, the maximum file length is 4k tokens. When using Anthropic's Claude, the maximum file length is 8k tokens.
• When changing multiple files, it may introduce conflicts between the files, as it does not know about the changed contents of the other files.
• It has only limited logic to control who is allowed to trigger it. If you are a repository member, you can trigger it. If others send a pull request, a repository member must allow the action to run manually.
• git-bob is incompatible with locally running open-source/-weight LLMs. This might make sense when being executed locally only. In the GitHub-CI this might be impossible.
• Recently tested claude-3-5-sonnet-20240620, gpt-4o-2024-08-06, github_models:gpt-4o, github_models:meta-llama-3.1-405b-instruct and gemini-1.5-pro-002 produced useful results.
