WHY IT NEEDS A POLICY

Why ensure_project needs a policy

With no description available, classification is highly uncertain. The name 'ensure_project' implies an idempotent operation (create if not exists or verify existence), which could be Write or Read. Given sibling tool 'ensure_product' likely has similar semantics, this is probably a Write or setup operation, but without evidence, confidence is very low.

From the tool's definition Tool description is empty and uninformative; tool name 'ensure_project' suggests an idempotent setup or validation operation.
