Agent evaluation for banking teams shipping AI

Agents in banking touch account data and money movement, and most teams have no record of what an agent actually did with either.

Every run scored for quality, performance and risk, and checked against the activity schema you define.

§01 / THE STAKESindustry: banking
The stakes

What's at stake in banking

For banking risk, compliance, and engineering teams, the stakes are regulatory exposure, audit gaps, and customer-facing errors that surface before anyone internally notices.

01
Misread credit files

A loan agent misreads a credit file or approves a transfer it should have flagged, and it surfaces as a customer complaint before your team catches it.

02
Broken transaction integrity

Did the agent move money, approve a limit, or change an account the way it was actually supposed to? Nobody can say for certain.

03
No run-by-run record

Teams can describe what an agent is supposed to do, but few can show what it actually did once it's calling three or four internal systems.

§02 / SOURCE OF TRUTHconnect: instrument + ingest
The solution

One source of truth for your banking agents.

Instrument the agent frameworks you build on, and ingest the systems those agents touch as custom spans. Every run, score and signal lands in one place.

§03 / THE LOOPpath: observe → evaluate → act
The loop

Observe. Evaluate. Act.

Every agent run in banking gets evaluated the same way, whether it's reading a credit file or reviewing a transaction. Each step below closes one of the problems above.

  • Observe. Scored for quality on every run, before an underwriter sees it
  • Evaluate. Checked against your activity schema before it counts as valid
  • Act. Written to an immutable audit trail, queryable per instance

§05 / IN PRODUCTIONproof: two real agents
The proof

Two agents banking teams are already shipping.

Hypothetical, but grounded in how banking teams deploy agents today.

Loan underwriting assistant

Low risk · 94/100

A LangChain agent pulls a credit bureau report, cross-references it against the loan origination system, and drafts a risk tier and approval recommendation for a human underwriter to sign off on. Every recommendation is scored through quality assessment → before it reaches the underwriter.

  • Credit bureau call, risk tier calculation, and draft recommendation each recorded as their own span
  • Validated against an activity schema, so a malformed or out-of-range output is flagged
  • Scored for quality and risk on every run

The team can show, for any single loan file, exactly what data the agent used and how it got to its recommendation.

Fraud investigation agent

Medium risk · 88/100

A Claude Agent SDK agent reviews transaction patterns across a customer's recent activity, annotates suspicious transfers with its reasoning, and surfaces a ranked case list in the fraud team's queue for a human analyst to action. Each ranked case carries a risk score → so the queue surfaces the transactions that matter most first.

  • Every transaction reviewed and every annotation written captured as a span with its own schema
  • Annotations checked to confirm they cite a real transaction, not a fabricated one
  • A configurable risk profile weights false positives against missed cases

The fraud team can trace a flagged case back to the exact transactions the agent used, and stop a single run without pulling the whole system offline.

Frequently asked questions

Can Prefactor instrument our existing banking agents without re-architecting?
Yes. There are native SDKs for the frameworks you build on, a TypeScript and Python core SDK for anything else, and OpenTelemetry ingest for closed tools you can't reach with an SDK — no gateway in your request path and no rebuild of your agents.
Can we bring our own banking systems and metrics into a run?
Yes, through custom spans. Attach data, evaluations or quality signals from any system your agents touch — Credit bureau, Loan origination system, Core banking and more — so every evaluation is grounded in what actually happened, not just the model output.
How does evaluation work on each run?
Every run is scored for quality and risk and checked against the activity schema you define. A run that breaches it can be held for review, escalated to a person, or blocked before it acts.
How is this different from an observability tool?
Tracing tells you what an agent did. Prefactor scores it and can hold or block the next action before it runs — observation plus enforcement, and one queryable record for every agent, not just a dashboard.
