WHY IT NEEDS A POLICY

Why add_knowledge needs a policy

This tool creates or modifies data in a Notion database by adding new knowledge entries. It is reversible (entries can be edited or deleted later), making it a Write action rather than Destructive. The severity is medium because unauthorized additions could corrupt the knowledge base with incorrect information, but the impact is limited to one database and can be remediated by deletion or correction.

From the tool's definition Tool name 'add_knowledge' and description '添加新知識到程式開發知識庫' (Add new knowledge to programming development knowledge base) directly indicate data creation/modification.
