AWS nova medium security documentation change
Summary
Enhanced security instructions to prevent tool disclosure, improved grammatical clarity in tool definitions, and added API-specific context
Security assessment
Explicitly strengthened security controls by adding colon to disclosure denial phrase ('ALWAYS say:') and emphasized non-disclosure requirements. This directly addresses potential information leakage vulnerabilities in assistant responses.
