The Challenge

Agency-delivered legacy bot had a 12% policy violation rate and hallucinated unsupported refund rules, creating severe brand risk.

The client was handling 50,000+ monthly customer inquiries through a combination of an outsourced tier-1 support desk and a fragile, prompt-only ChatGPT integration.

Responses contradicted official SLA policies, hallucinated unreleased product capabilities, and frequently failed to access real-time CRM user history.

The business was facing rising support overhead costs while customer satisfaction scores (CSAT) were plummeting.

Legacy System Bottlenecks
01

12% Policy Failure Rate: Bot granted unauthorized discount exceptions and return approvals.

02

No Deterministic Verification: Output was generated directly by the LLM without pre-dispatch policy checks.

03

Context Blindness: Unable to ground responses in active Zendesk customer history or subscription tiers.

System Topology

Deterministic Hybrid RAG & Policy Enforcement Pipeline

A multi-layer architecture decoupling intent classification, knowledge retrieval, and output guardrails to guarantee 100% compliance before message dispatch.

Architectural Trade-Offs

01

Deterministic Guardrails Over Pure Prompt Engineering

Superseded: Single Prompt ChatGPT Wrapper • Unconstrained LangChain Agents

Prompt engineering alone cannot guarantee 0% hallucination rates. Wrapping the model with strict Pydantic schema validation and post-generation policy checks prevented 100% of policy breaches.

02

Hybrid Dense/Sparse Vector Search Over Standalone Vector DB

Superseded: Isolated Pinecone Index • Client-side Regex Search

Pure cosine similarity fails on exact alphanumeric part numbers and SKU codes. Hybrid search ensures both conceptual understanding and exact term discovery.
