classifications:
  - name: no-ads
    description: >-
      A commit message contains a co-authored-by line or other advertising
      for an AI model, such as a "generated with" footer.
    polarity: negative
    threshold: 80
  - name: no-secrets
    description: >-
      The diff adds a secret as literal text: a password, API key, access
      token or private key. A path or name that points at a secret is not
      one.
    polarity: negative
    threshold: 60
  - name: no-lint-suppression
    description: >-
      The diff adds a Rust `#[allow(clippy::...)]` or `#![allow(clippy::...)]`
      attribute instead of fixing what the lint reports.
    polarity: negative
    threshold: 70
  - name: no-debug-leftovers
    description: >-
      The diff adds leftover debugging: a `dbg!` call, a print statement
      that only inspects a value, or a block of commented-out code.
    polarity: negative
    threshold: 70
  - name: no-dead-code
    description: >-
      The diff adds a function, type, option or module that nothing in the
      diff calls, uses or registers, and that is not a test, a trait
      implementation or public API.
    polarity: negative
    threshold: 75
  - name: tests-with-behaviour
    description: >-
      The decision-making logic a change adds or alters in Rust or
      application code has a new or updated test that exercises it: pure
      functions, state transitions, request and response handling, parsing,
      validation. A new code path with real logic and no test does not
      match, and neither does a bug fix with no regression test. Thin glue
      needs no test of its own: UI component wiring, JSX or markup, a
      routing table, registering an event listener, re-exporting, or
      calling a function that is already tested. A diff whose changed files
      are all test code (a fixture under `nix/module-eval/`,
      `nix/checks.nix`, a crate's `tests/` directory, or Rust inside
      `#[cfg(test)]` or a `#[test]` function) changes no behaviour: the
      question is not applicable. So is a diff that changes only
      documentation. A NixOS module assertion, a Grafana/alerting rule, or
      the literal text of a log or tracing message is not held to this
      either. A PR that changes logic and tests together matches.
    polarity: positive
    threshold: 65
  - name: docs-updated
    description: >-
      A change to what an operator or user sees, such as a command, flag,
      option, endpoint, service or default, updates the matching page under
      docs/ or the crate's README in the same diff. For a nix option whose
      own default, type or meaning changes, an updated `description` on that
      option counts as the documentation. It does not cover a change in what
      a service does for operators across hosts, such as what it scrapes,
      serves or publishes: that needs a docs/ page or README. A nix option
      declared `internal = true` or `visible = false` is not something an
      operator sees, so adding or changing one needs none of these.
    polarity: positive

  - name: one-purpose
    description: >-
      Every change in the diff serves what the commit messages say the PR
      does, and nothing unrelated is bundled in.
