    • CI workflow runs a lint or format check.
    • CI runs type checking (tsc, mypy, cargo check, etc.).
    • Optional: report test coverage in CI.Upload coverage to Codecov, Coveralls, or report it with `--coverage` flags.
    • CI caches dependencies for faster runs.
    • CI tests across multiple environments or versions.
  • Linting and formatting100
    • Rust linting configured (cargo clippy in CI, cargo fmt in CI).
  • Reproducibility82
    • Lockfile present (candle-examples/examples/marian-mt/python/requirements.txt). 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.
    • Dependabot configured for cargo.
    • Dependabot only covers one ecosystem (−8 pts). Covering 2+ ecosystems earns the full +20 pts.Add additional package-ecosystem entries (especially github-actions) to keep all dependencies current.
  • Issue and PR templates0
    • No issue or PR templates found (−100 pts).Add .github/ISSUE_TEMPLATE/ with bug_report.md and feature_request.md to guide contributors. It dramatically improves issue quality.
