    • README documents how to install the project.
    • README documents how to run the project.
    • 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 MIT.
  • Contributing guide78
    • Contributing guide is detailed and thorough.
    • Contributing guide lacks a setup section (−12 pts).Show new contributors how to get a local dev environment running.
    • Contributing guide lacks a code style section (−8 pts).Describe your linting/formatting rules and how to run them (e.g. npm run lint, ruff check .).
    • Contributing guide explains how to run tests.
    • Contributing guide describes the PR/review workflow.

  • Tests90
    • Test files detected (tracing-attributes/tests).
    • Rust workspace with test files detected. Run with `cargo test --workspace`.
  • CI/CD85

    Not applicable?

    • CI is configured (.github/workflows/CI.yml).
    • CI workflow runs tests.
    • 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.
    • 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 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.
  • Reproducibility50
    • No Cargo.lock committed. Correct for Rust library crates (Rust ecosystem convention).For Rust binaries/applications, commit Cargo.lock. For library-only crates, omitting it is the recommended practice per the Cargo guide.
    • 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.
  • Issue and PR templates100
    • Issue or PR templates present.
    • Security policy present.
