Example — Safety-focused gate

This example mirrors the safety-and-blocking style policy from geval init: hard BLOCK rules when model or retrieval quality crosses a line.

Signals

Your pipeline should emit metrics such as:

hallucination_rate (on component: generator)
context_relevance (on component: retrieval)

Policy idea

Priority 1 — If hallucination rate exceeds a ceiling → BLOCK with a clear reason.
Priority 2 — If retrieval relevance falls below a floor → BLOCK.

Contract

List the policy file(s) in contract.yaml:

name: release-gate
version: "1.0.0"
policies:
  - path: policies/safety-and-blocking.yaml

Run

geval validate-contract contract.yaml
geval check --contract contract.yaml --signals signals.json
