WHY IT NEEDS A POLICY

Why register_code_artifact needs a policy

The name indicates a write operation that creates or modifies a record (registration) for code artifacts. Without a description, confidence is reduced, but the 'register_' prefix typically implies recording/storing data reversibly. Given the context of a research companion system with features like 'add_journal_entry' and 'add_memory_entry' (both Write operations), this likely creates a new artifact record.

From the tool's definition Tool name 'register_code_artifact' suggests creating or recording a code artifact entry in a system.
