    • If your project uses environment variables, add a .env.example listing them (+10 pts).Add a .env.example listing all required environment variables so contributors know what to set up.
  • License100
    • Licensed under MPL-2.0.
  • Contributing guide87
    • Contributing guide is present (+6 pts for length); 400+ words earns the full +12 pts.
    • Contributing guide includes setup/install instructions.
    • Contributing guide describes code style expectations.
    • Contributing guide explains how to run tests.
    • Contributing guide describes the PR/review workflow.
    • Contributing guide has no code examples (−5 pts).Add code blocks showing example commands for setup, running tests, and submitting a PR.
    • Optional: add a Code of Conduct (+5 pts).A CODE_OF_CONDUCT.md signals that your project is welcoming. GitHub has a template you can add in one click.

  • Tests90
    • Test files detected (tests).
    • Cargo.toml has dev-dependencies and test files are present.
  • CI/CD57

    Not applicable?

    • CI is configured (.github/workflows/cbindgen.yml).
    • The CI workflow does not appear to run any tests (−28 pts).Add a step like `run: npm test`, `run: pytest`, or `run: tox` to your workflow file.
    • CI runs on pull requests, not just on pushes to main.
    • CI does not appear to run a linter (−15 pts).Add a lint step (e.g. `npm run lint`, `ruff check .`, `cargo clippy`) to catch style issues automatically.
    • Optional: add type checking to CI.Add `tsc --noEmit`, `mypy`, or `cargo check` to catch type errors before they merge.
    • Optional: report test coverage in CI.Upload coverage to Codecov, Coveralls, or report it with `--coverage` flags.
    • CI tests across multiple environments or versions.
  • Linting and formatting40
    • Rust projects have clippy available. Run `cargo clippy` for linting.
    • CI does not appear to run `cargo clippy` (−40 pts vs enforcing it in CI).Add `cargo clippy -- -D warnings` and `cargo fmt --check` as CI steps.
    • No rustfmt.toml found.Add a rustfmt.toml to enforce a consistent code style across contributors.
  • Reproducibility75
    • Lockfile present (Cargo.lock). Installs are reproducible.
    • No Dockerfile or runtime version pin found. Adding one earns +10 pts.Add a Dockerfile, .nvmrc, or .python-version to pin the runtime version and make the environment reproducible.
    • No Dependabot config (adding it earns up to +20 pts).Add .github/dependabot.yml with at least one package-ecosystem entry so dependencies are updated automatically.
    • Cargo.toml uses Rust edition 2021 (current best practice).
  • Issue and PR templates0
    • No issue or PR templates found (−90 pts).Add .github/ISSUE_TEMPLATE/ with bug_report.md and feature_request.md to guide contributors. It dramatically improves issue quality.
    • Optional: add a SECURITY.md.A SECURITY.md explains how to responsibly disclose vulnerabilities. Worth adding once the project has real users.
