Missing Type Annotation (ARCH3193)

Key typescript.quality.missing-type-annotation · Severity info · Category quality

Functions on the public API surface that lack explicit parameter and return types let inferred types drift silently and leave the contract ambiguous. Public boundaries should be explicitly typed.

Incorrect

export function parseAmount(raw) {
  return Number(raw) / 100;
}

Correct

export function parseAmount(raw: string): number {
  return Number(raw) / 100;
}

Fix

Add explicit parameter and return types to public functions.
