Use this Manus spend tool when you need to send a follow-up or answer a manus messageaskuser waiting event. It contacts the configured Manus API v2 POST /v2/task.sendMessage endpoint and requires a request-scoped x-manus-api-key. Resumes/continues a task; dry-run and confirm required. It is dry-run by default and requires confirm=true after approval before the provider write executes. The result is a compact, secret-redacted object and never includes the Portal grant or provider credential.
