isValidSlug

function isValidSlug(value: string): boolean;

Starts with a letter, then letters, digits, hyphens and underscores — the shape a URL segment or a key can take. Spaces, leading digits and an empty string are rejected.

isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.
