The Agentforce eval harness we ship with every rollout

Prompt evals, regression suites, guardrail tests and observability — what production-grade agent governance actually looks like.

CRMPRACTICE AI Engineering14 July 202610 min read
TL;DR
  • Without evals, agents drift silently — you find out via a CSAT drop, not a monitor.
  • A minimum viable harness has 4 layers: golden set, regression suite, guardrail battery, live observability.
  • Cost of building it is 3–5% of programme spend — cost of skipping it is measured in incidents.
01

The four layers

Golden set (curated ideal Q&A / actions), regression suite (prior incidents replayed on every model or prompt change), guardrail battery (PII, jailbreak, policy, tool-misuse), and live observability (reasoning traces, tool-call outcomes, human overrides).

02

What to score

Task completion, factual grounding, tool-selection accuracy, policy compliance, latency P95, cost per resolution. Track weekly, alert on regression.

03

Who owns it

A single accountable owner — usually a Salesforce architect paired with a data / AI engineer — inside a lightweight AI Council. Not the vendor. Not IT ops.

SMART framework

How to make this specific, measurable and shipped.

A concrete goal shape for turning this insight into a board-defensible programme.

Specific

Stand up a 4-layer eval harness for the first production Agentforce use case.

Measurable

Regression pass rate, guardrail trip rate, mean time to detect drift, incident count.

Achievable

3-sprint build with reusable harness template — subsequent use cases inherit 80%.

Relevant

Direct control on AI risk register items owned by CISO, CAIO and general counsel.

Time-bound

Harness live before first production deployment; weekly reporting from week one.

Model it

Put numbers on it.

An interactive model calibrated to the shape of programmes we run. Tune the inputs to your reality — the outputs recompute instantly.

ROI Calculator

Cost of skipping evals (risk-adjusted)

Compare eval harness investment against the expected annual cost of undetected agent incidents.

Inputs
Estimated outcomes
Expected incident cost (no evals) / yr
$8.10M
Cost avoided by evals / yr
$6.08M
Net year-1 value
$5.86M
Year-1 ROI
2,661%
Assumptions
  • Incident = policy breach, wrong tool call, hallucination reaching customer.
  • Detection lift is conservative — high-maturity harnesses reach 85–95%.
  • Excludes reputational and regulatory tail-risk — modelled separately.
Key takeaways
  1. 01Ship the harness before the agent.
  2. 02Score outcomes, not just outputs.
  3. 03One owner. Weekly cadence. No exceptions.
