OptionalrequiresOptional top-level input property whose presence satisfies this
precondition. When declared and absent from the invocation input, the host
surfaces summary as a pre-dispatch not-ready signal naming this input,
rather than dispatching the worker and returning its runtime error.
Untrusted human-readable statement of what must be true, or what to supply, before this command is ready.
Producer-declared runtime readiness note for one project command. It is static, data-free, UNTRUSTED presentation copy — never authority, never a grant, never a consent input. Disclosed at describe time so a caller learns a runtime precondition (e.g. "a default voice must be configured, or pass an explicit engine") BEFORE the first invocation, and — when
requiresInputnames a top-level input the caller can supply — enforced pre-dispatch as an actionable not-ready signal instead of a post-dispatch worker error.
