WHY IT NEEDS A POLICY

Why ims_graph_create_lesson needs a policy

The tool creates and stores a lesson entity (likely a knowledge or learning record) within the IMS graph backend. This is a Write operation because it modifies the graph state by adding new data reversibly. Severity is medium because uncontrolled lesson creation could pollute the knowledge base and consume storage, but the effects are not destructive (deletable), not financial, and not code execution.

From the tool's definition Tool name includes 'create_lesson' indicating a data creation operation; sibling tools on the same server include create_bug, create_component, create_correction, and create_decision, establishing a pattern of reversible write operations for persisting…
