Agent evaluation for manufacturing teams shipping AI

An agent recommending a maintenance action or flagging a defect is one step from a physical outcome on the floor, and most teams cannot trace a bad call back to the data that caused it.

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

§01 / THE STAKESindustry: manufacturing
TL;DR

Every manufacturing agent run gets watched, evaluated for quality and risk, and checked against the rules you set. One record answers what any agent did, with evidence ready for review.

The stakes

What's at stake in manufacturing

For plant leads, quality managers, and the engineering teams behind them, the stakes are unplanned downtime, defective units reaching a customer, and no record of what an agent based a recommendation on.

01
Misread trends, stopped lines

A predictive maintenance agent that misreads a sensor trend does not just produce a wrong number, it can lead to unplanned downtime or a defective unit reaching a customer.

02
Recommendations become physical actions

An agent's call becomes a work order, a line stoppage, or a quality hold, triggered on a misread of the underlying sensor or production data.

03
No provenance per work order

Most plants can describe what a maintenance or quality agent is supposed to do, but few can show which sensor readings actually drove a specific work order.

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

One source of truth for your manufacturing 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 on the floor is observed span by span, evaluated against the data that triggered it, and held before it acts. Each step below closes one of the problems above.

  • Observe. Scored for quality on every run, before a technician sees it
  • Evaluate. Checked against the sensor pattern that triggered it, before it reaches the line
  • Act. Written to an immutable audit trail, queryable per machine
  • OSHA (US workplace safety)
  • ISO 9001
  • Sector-specific safety codes
  • SOC 2

§05 / IN PRODUCTIONproof: two real agents
The proof

Two agents manufacturing teams are already shipping.

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

Predictive maintenance agent

Low risk · 91/100

A Semantic Kernel agent monitors sensor data from production equipment, identifies patterns that precede a failure, and creates a work order in the maintenance system for a technician to review. Every work order is scored through quality assessment → before it reaches the floor.

  • Each sensor reading the agent evaluates and each work order it creates recorded as its own span
  • Validated against an activity schema that checks the stated cause actually matches the sensor pattern that triggered it
  • Scored for quality and risk on every run

A maintenance lead can trace a specific work order back to the exact sensor readings that triggered it, instead of taking the recommendation on faith.

Quality inspection agent

Medium risk · 86/100

A LangChain agent reviews production line vision and sensor data to flag potential defects, logging each flagged unit to the quality management system for a human inspector to confirm. Each flagged unit carries a risk score → so the inspector queue surfaces the units that matter most first.

  • Every unit the agent evaluates and every defect it flags captured as a span
  • Flags checked to confirm they cite specific sensor or image data rather than an unsupported judgment
  • A configurable risk profile weights defect types by severity

A quality inspector can see exactly what production data supported a specific defect flag before confirming or overriding it.

Frequently asked questions

Can Prefactor instrument our existing manufacturing 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 manufacturing systems and metrics into a run?
Yes, through custom spans. Attach data, evaluations or quality signals from any system your agents touch — Quality management system, Sensor historian, Maintenance system 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.
Where does our manufacturing data live?
Prefactor's primary infrastructure runs in Australia. For enterprise engagements it deploys where your data needs to live: your region, or your environment. Residency is part of the engagement conversation, not an add-on.
