The description, line by line

12 lines Line numbers are v2.1.268 on the left and this capture on the right.
1 1 DEPRECATED: Background tasks return their output file path in the tool result, and you receive a <task-notification> with the same path when the task completes.
2 2 - For bash tasks: prefer using the Read tool on that output file path — it contains stdout/stderr.
3 3 - For local_agent tasks: use the Agent tool result directly. Do NOT Read the .output file — it is a symlink to the full subagent conversation transcript (JSONL) and will overflow your context window.
4 4 - For remote_agent tasks: prefer using the Read tool on the output file path — it contains the streamed remote session output (same as bash).
5 5
6 6 - Retrieves output from a running or completed task (background shell, agent, or remote session)
7 7 - Takes a task_id parameter identifying the task
8 8 - Returns the task output along with status information
9 9 - Use block=true (default) to wait for task completion
10 10 - Use block=false for non-blocking check of current status
11 11 - Task IDs can be found using the /tasks command
12 12 - Works with all task types: background shells, async agents, and remote sessions
