Return all blocked tasks for a run.
AI agents call get_blocked_tasks to retrieve information from Dag Planner without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about blocked tasks within a workflow run. It performs a read-only operation that retrieves state information without modifying, deleting, or executing any tasks. The verb 'return' and the passive nature of listing blocked tasks confirm it falls under the Read category.
From the tool's definition Tool name 'get_blocked_tasks' and description 'Return all blocked tasks for a run' indicate a retrieval operation with no side effects.
