Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with "bug" and "help wanted" is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with "enhancement" and "help wanted" is open to whoever wants to implement it.

Write Documentation

metamaska could always use more documentation, whether as part of the official metamaska docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/happyhackingspace/metamaska/issues.

If you are proposing a feature:

• Explain in detail how it would work.
• Keep the scope as narrow as possible, to make it easier to implement.
• Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here's how to set up metamaska for local development.

1. Fork the metamaska repo on GitHub.

2. Clone your fork locally

   $ git clone git@github.com:your_name_here/metamaska.git
   

3. Ensure uv is installed.

4. Install dependencies:

   $ uv sync --all-groups
   

5. Create a branch for local development:

   $ git checkout -b name-of-your-bugfix-or-feature
   

   Now you can make your changes locally.

6. When you're done making changes, check that your changes pass the tests:

   $ make test
   

7. Commit your changes and push your branch to GitHub:

   $ git add .
   $ git commit -m "Your detailed description of your changes."
   $ git push origin name-of-your-bugfix-or-feature
   

8. Submit a pull request through the GitHub website.

Retraining the Model

To collect fresh training data and retrain the classifier:

$ make collect-data   # downloads datasets → data/processed/dataset.json
$ make train          # trains pipeline → metamaska/models/payload_clf.joblib
$ make hf-upload      # uploads model to HuggingFace Hub

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

1. The pull request should include tests.
2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.md.
3. The pull request should work for Python 3.13+. Check https://github.com/happyhackingspace/metamaska/actions and make sure that the tests pass for all supported Python versions.

Tips

$ uv run pytest tests/test_metamaska.py

To run a subset of tests.

Deploying

A reminder for the maintainers on how to deploy. Make sure all your changes are committed (including an entry in CHANGELOG.md).

Pushing to main triggers the CI workflow which automatically determines the next version, creates a tag, and pushes it. The release.yml workflow then builds and publishes to PyPI.
