react-doctor/unused-type

A reachable module exports a type that no module imports

Validation prompt

Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.

This opt-in project rule reports a type export with no in-repository consumer after tracing type imports and re-exports. Confirm declaration consumers, generated clients, and external package consumers before accepting the finding. Reject types that remain part of a supported public API outside the scanned repository.

Evidence boundary

The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.

Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.

Record one outcome:

• Confirmed failure: The required evidence establishes the violation.
• Rejected: A documented exception or false-positive predicate applies.
• Needs evidence: Named evidence can still be collected.
• Unavailable: Required evidence cannot be collected in this run.
• Waived with evidence: An authorized, scoped exception applies to an established failure.
• Observation: The review records an optional tradeoff without claiming a defect.

A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.

Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.

Review a candidate correction

Apply this candidate correction only after the required evidence confirms the risk.

Reported pattern

export interface LegacyCardProps {
  title: string;
}

export const Card = ({ title }: { title: string }) => <h2>{title}</h2>;

Candidate corrected pattern

export const Card = ({ title }: { title: string }) => <h2>{title}</h2>;

Fix prompt

Apply this candidate correction only after the required evidence confirms the risk.

Delete an obsolete type. Remove only the export keyword when local annotations still use it. Update barrels and public declarations when the exported surface changes, then run a full React Doctor scan and TypeScript checks.

Repository-wide copy prompt

Use this repository-wide prompt only after validating each occurrence. For one occurrence, use the guidance above.
