RAG Pipeline with Guardrails

Most RAG demos stop at retrieval quality. This project is about the next layer: making grounded answers traceable, adding safety checks around risky behavior, and turning those checks into explicit release decisions instead of after-the-fact commentary.

Best read for groundedness, safety, and release discipline treated as one system.

Quick Read

The missing layer in most RAG work is operational discipline.

2 Domains

The pipeline is intentionally grounded in both real travel workflows and synthetic seller-intelligence scenarios.

24 Evaluation cases

Enough to prove the pipeline, guardrails, and reporting logic work together end to end.

PASS Release gate verdict

The point is not the score alone. The point is having a score that can block or allow a release explicitly.

The problem

Retrieval quality alone does not make a feature shippable.

A grounded answer can still be risky, misleading, or hard to defend. The useful product question is whether the system can produce grounded answers, flag unsafe behavior, and explain why a release should move forward or stop.

System scope
  • Dual-domain RAG pipeline with corpus-aware retrieval.
  • Pre and post guardrails for prompt injection, PII, toxicity, and groundedness.
  • Traceable outputs with citations, confidence, and verdict reasons.
  • Benchmark reporting and PASS/WARN/BLOCK release logic.
Why this matters

This is the bridge between “the AI prototype looks promising” and “the team knows enough to launch responsibly.” That transition is where a lot of teams still get vague. I wanted the decision logic to be concrete.

Scope
  • Travel corpus for SproutRoute use cases and a generalized seller workflow corpus for enterprise recommendation scenarios.
  • Evaluation export in JSON and Markdown.
  • Release gate tied directly to guardrail outcomes.
  • Designed to fit with the evaluation and safety projects elsewhere in the portfolio.
Executive Summary

A good RAG system needs evidence, not just retrieval.

The answer has to be grounded, the risky behavior has to be caught, and the launch decision has to be legible. Once those three pieces live together, the system starts to look like production infrastructure instead of a retrieval demo.

Why it matters

  • I think about RAG as a product system, not just a retrieval pipeline.
  • I know how to combine safety checks and evaluation evidence into launch logic.
  • I can connect technical quality back to product release decisions clearly.
Deep Dive

The interesting part is how the pieces fit together.

Capability

Dual-domain retrieval

The corpora cover both travel and seller workflows so the same pipeline can be tested against materially different user contexts.

Capability

Pre and post guardrails

Risky input and output behavior gets checked on both sides, which makes the pipeline safer and the evaluation more meaningful.

Capability

Evaluation harness

The benchmark suite is not there for decoration. It proves the pipeline and makes regressions comparable over time.

Capability

Release gate

Policy thresholds turn raw evaluation output into a decision artifact that can actually be used in launch reviews.
