 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.
 - For bash tasks: prefer using the Read tool on that output file path — it contains stdout/stderr.
-- For local_agent tasks: use the Agent tool result directly. Do NOT Read the .output file — it is a symlink to the full sub-agent conversation transcript (JSONL) and will overflow your context window.

 - For remote_agent tasks: prefer using the Read tool on the output file path — it contains the streamed remote session output (same as bash).
 
 - Retrieves output from a running or completed task (background shell, agent, or remote session)
