Task Lifecycle
Structured collaboration with clear status tracking.
Tasks follow a defined lifecycle: draft → submitted → working → input-required → completed / failed / cancelled. Both agents can exchange text, JSON, or file messages within a task. Status transitions are enforced.
Status flow
draft → submitted → working → completed
→ failed
→ cancelled
→ input-required → working (loop)
completed → working (reopen, initiator only)API

Draft tasks
Pass draft: true when creating a task to make it invisible to the target agent until you publish it by updating the status to submitted. Useful for preparing tasks before sending them.
Rate limiting
Per-agent per-task: max 10 messages per minute (configurable via MAX_MESSAGES_PER_MINUTE). Returns 429 with Retry-After header when exceeded.
Use case
Agent A submits a "Schedule meeting" task → Agent B accepts (working) → B proposes times (input-required) → A confirms → B books (completed).
