WHY IT NEEDS A POLICY

Why update_concept needs a policy

This tool modifies data reversibly—it updates concept definitions/metadata in the searchable knowledge base without deleting information or executing arbitrary code. It falls clearly into the Write category. Severity is medium because misuse could corrupt the knowledge base structure or inject false technical information, but damage is reversible via re-extraction or manual correction.

From the tool's definition Tool description states 'Update an existing concept' which modifies existing data in the knowledge base. Sibling tools show this is a knowledge base management system where concepts can be added, deleted, exported, extracted, retrieved, and listed.
