WHY IT NEEDS A POLICY

Why update_board_item needs a policy

The tool updates existing board items (reversible modification of data) rather than deleting them or executing external code. Within the context of a decision memory system, updating board items is a Write operation affecting the agent's persistent architectural state.

From the tool's definition Tool name 'update_board_item' clearly indicates modification of board state; description is empty but sibling tools like 'add_decision', 'add_constraint', and 'get_board_items' establish that the server manages persistent decision memory and board artifacts.
