WHY IT NEEDS A POLICY

Why lithtrix_register needs a policy

This tool creates a new agent registration and generates an API key, which are irreversible administrative changes to the system. However, it does not delete data (not Destructive), move money (not Financial), or execute arbitrary code (not Execute in the dangerous sense).

From the tool's definition Tool description states 'Register a new agent' and 'receive a one-time API key' — these are creational operations that modify system state by adding a new agent identity and issuing credentials.
