Warranty & Claims-Triage AI Agent
Match a claim to the unit that was built, read coverage against the policy in force, group repeat failures and route safety signals — a warranty administrator decides coverage and cause.

What this agent does
Triages the claim, does not decide it
In
- 01
Take the claim, the dealer or customer narrative, the coded parts and the labour lines as submitted.
- 02
Pull the unit's build record — serial, plant, build date, option content and service history.
Reason
- 03
Match the claim to the unit that was actually built, not to the nominal bill of materials.
- 04
Read coverage against the policy version and the market terms in force for that unit.
- 05
Group claims sharing a failure signature across build dates, plants, suppliers and option content.
Decide
- 06
Route anything with a safety signature to product safety on arrival, before any coverage step.
- 07
Hold claims the build record, the narrative or the policy version does not settle.
Out
- 08
Assemble the technical-review pack — unit, narrative, matched cohort, part history and prior claims.
- 09
Prepare a supplier-recovery file where the evidence points at a bought part, for a person to send.
Product statement
The agent triages, matches and assembles. Coverage, cause and any field action are decided by the people your process names, and a claim carrying a safety signature leaves the cost path on arrival.
Example workflow
One claim, end to end
- 1Claim receivedA dealer or distributor portal, a service report, a field claim or a customer contact
- 2Unit identifiedSerial, plant and build date, then option content, prior claims, campaigns run and service history
- 3Safety signature screenedFire, heat, injury, loss of control or unintended movement — routed to product safety before anything else
- 4Coverage read and cohort matchedPolicy version and market terms in force, duplicates and resubmissions marked, same-signature claims grouped
No human action required
Stages 1 to 4 run without a person in the loop — matching, the safety screen, the coverage reading and the grouping all finish before anyone is asked to decide. A safety signature ends that stretch on the spot.
Reaches the administrator with the evidence attached.
Held for a warranty engineer to work.
Warranty administrator or engineer
Reads the claim against the build record, the terms in force and the matched cohort, then decides coverage and cause.
Decide coverage · Correct · Send to technical review
Decided — handed back
- 6Pack assembled and filedWritten to the warranty system only where access and procedure allow; the coverage field stays empty
- 7Outcome evaluatedAdministrator agreement, build-match accuracy, duplicate catches and cohorts against confirmed field actions
Safety exit
A safety signature leaves this lane at stage 3, whatever the coverage reading says.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Approving, denying or paying a claim.
- Deciding the cause of a field failure.
- Deciding that a field pattern is a defect.
- Scoping, starting or announcing a field action.
Automation boundary
Agent acts unaided
- ✓Match a claim to the unit's build record, option content and service history.
- ✓Read coverage against the policy version and the market terms in force.
- ✓Group claims sharing a signature, and mark duplicates and resubmissions.
- ✓Route safety signatures on arrival and assemble the pack for a person to decide.
The agent writes the triage record and the routing flag. The coverage decision and the cause are not its to write.
- Reporting to a product-safety regulator.
- Charging a supplier or raising a debit note.
- Changing coverage rules, terms or thresholds.
- Setting the affected population for a campaign.
Example output
One claim on one unit, annotated
Everything the agent puts forward is attached to the unit it was built as and the terms in force when it went into service.
Triage output · single claim

As received
The claim, the unit it names and the words the dealer typed — read from the submission and the build record.
Evidence used
- Build record, plant 2
- Same-signature cohort
- Prior claims, same unit
Why it left the cost path
Heat and a loss of drive is a product-safety question, not a coverage one.
What the score decides
Confidence ranks the queue, never whether a safety signature is escalated.

Where the value lands
Value 01 – 04
Every claim received
Dealer portal, field report or customer contact
Work to your own build records
Use the unit's build record and option content, the policy version in force for that market, and the campaigns already run on it.
Give the administrator the whole unit
The build record, the option content, prior claims and the matched cohort arrive with the claim, so the decision starts from the unit that was built.
Send the unsettled, route the unsafe
Claims the record does not settle reach an engineer, and anything reading as a safety matter goes to product safety whatever the cost path would have said.
Build an evidence trail
Retain the claim, the narrative, the build record read, the policy version, the cohort, the confidence and the decision a person made — on both paths.

Agent controls
Six layers between the model and a coverage decision
Each control wraps the one inside it. A triage clears every layer before an administrator sees it, and the safety route runs before any of the cost logic.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Keep the unit and the terms right
- L3
- Takes safety out of the cost path
- L4 – L5
- Keep the decision with a person, trail intact
- L6
- Pulls automation back when signals degrade
How Nestack evaluates it
Evaluate the whole triage — not only the coverage it reads.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the pack the administrator opens
- E1Final-output evaluationDid the triage agree with what the administrator decided?
- E2Step-level evaluationDid it read the right build record, options and policy version?
- E3Tool evaluationDoes the pack tie back to the exact unit, claim and part lot?
- E4Emerging-pattern recallWere the cohorts it raised the ones that became field actions?
- E5Slice evaluationHow does performance change across model year, plant and market?
- E6Business outcomeWhat was reopened, re-coded, double-counted or recovered in error?
Floor — the coverage and cause a person decides
Failure modes
Where each failure originates in the agent
Seven failure modes plotted against the five stages of the agent lifecycle. None of them decides coverage or cause — the administrator's reading, the technical review and your product-safety process are the controls that stop them. If one gets through, the claim, the unit, the policy version and the cohort held in the record are what the re-review, the customer notification and the report to your safety owner are built from.

- Sev-2 · decided on the wrong unit or terms
- Sev-3 · the cohort is wrong and misleads
Affected slices
A recent build has not had time to fail yet
Claims arrive months after a unit ships, so last quarter's build carries fewer than it will end up with. A low-volume variant may hold too few to say anything at all. Nestack reports performance by slice, not only in total.
Slice performance — reported separately, not only in aggregate

Evidence-linked improvement
The cohort that became a field action is the answer key
Every claim an administrator re-decided, and every pattern a technical review confirmed, is scored again against what the agent said at the time.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Administrator disagreement, reopened claims, or a signature nobody raised until the field action.
- 02
Diagnose
Separated into build-record match, policy version, coded part, duplicate handling and cohort maturity.
- 03
Improve
Match keys, grouping rules and coverage logic change under your quality change control, with a named approver.
- 04
Verify
Re-scored on stored claims from that model year and plant, including the cohort that was raised too late.
- 05
Learn
The missed signature is kept as a standing case, and the delay itself goes to your emerging-issue review.
Learn → Detect
The return edge. Nothing in this loop moves a reporting clock — a pattern that looks like a defect goes to the people who own product safety when it is seen, not when the next release is verified.
Typical build scope
Twelve workstreams across six weeks
The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, records and terms, triage and grouping, evaluation, integration, then supervised running and handover.

- Reading the band
- Safety-signature routing is built in week 3 with the people who own product safety — before any claim is triaged for cost in week 5.
- At the end of W6
- Claims have run alongside your existing queue and been decided by the administrators who own coverage, with every safety signature going where it goes today, then Agent Care takes over monitoring.
