Problem

Support agents need to identify which transaction a complaint refers to without requesting secrets, inventing authorization, or promising financial actions they cannot perform.

Contribution

  • Kept the optional LLM outside the critical decision path.
  • Added negation-aware rules against asking for PIN, OTP, password, or card details.
  • Documented signal-based matching and Banglish-language limitations.
