/** * Boolean that also accepts the string literals "true"/"false". * * Tool inputs arrive as model-generated JSON. The model occasionally quotes * booleans — `"replace_all":"false"` instead of `"replace_all":false` — and * z.boolean() rejects that with a type error. z.coerce.boolean() is the wrong * fix: it uses JS truthiness, so "false" → true. * * z.preprocess emits {"type":"boolean"} to the API schema, so the model is * still told this is a boolean — the string tolerance is invisible client-side * coercion, not an advertised input shape. * * .optional()/.default() go INSIDE (on the inner schema), not chained after: * chaining them onto ZodPipe widens z.output<> to unknown in Zod v4. * * semanticBoolean() → boolean * semanticBoolean(z.boolean().optional()) → boolean | undefined * semanticBoolean(z.boolean().default(false)) → boolean */export function semanticBoolean<T extends z.ZodType>( inner: T = z.boolean() as unknown as T,) { return z.preprocess( (v: unknown) => (v === 'true' ? true : v === 'false' ? false : v), inner, )}
