WHY IT NEEDS A POLICY

Why memory_create_via_chat needs a policy

The 'create' verb in the tool name strongly suggests writing or persisting data (likely conversation memory or state). Without description details, this appears to be a Write operation rather than Read (no query semantics) or Destructive (no 'delete'/'purge' language). Severity is medium because memory operations could track or persist unintended information, but lack of detail justifies moderate confidence (0.60).

From the tool's definition Tool name 'memory_create_via_chat' contains 'create', indicating irreversible data creation or persistence. No formal description provided to disambiguate scope or reversibility.
