@studnicky/clean-diagnostics ​

Disallows lint, type, and coverage suppression comments. The rule examines every source comment and reports values matching its suppression pattern, including eslint-disable, eslint-disable-line, eslint-disable-next-line, eslint-enable, @ts-ignore, @ts-expect-error, @ts-nocheck, tslint:disable, tslint:disable-line, tslint:disable-next-line, c8 ignore, c8-ignore, istanbul ignore next/if/else, and a per-rule config-disable form (eslint <rule>: "off", 'off', or 0).

This rule reports only. An autofixer that deletes from a suppression comment's start to end-of-line is unsafe for an inline block comment: when the comment shares its line with code — a coverage-suppressing block comment preceding an exported const declaration on the same line, for example — the deletion range extends past the comment onto that code. An autofixer that instead removes exactly the comment's own range is equally unsafe: it lets the suppressed diagnostic reappear, which can turn a green tree red at a location unrelated to the edit, and removing a suppression that is load-bearing for a generated or vendored file changes what CI reports rather than what the code means. This rule ships no autofixer for either reason — only a transformation that cannot break the build or change program meaning gets one here, and removing a suppression comment is a decision about which underlying problem to confront, which belongs to a person.
