• Contract tier: agent_ready
• Risk: read
• Catalog version: manus-2026.07.12.2

Use this Manus read tool when you need to poll manus task events in compact form; use for async status and results. It contacts the configured Manus API v2 GET /v2/task.listMessages endpoint and requires a request-scoped x-manus-api-key. Polls event stream; check_task_progress wraps it for compact status. This is read-only and does not change remote state. The result is a compact, secret-redacted object and never includes the Portal grant or provider credential.
