Read the repair order, the technician's story, the parts used and the coverage in force, then assemble a claim file — the operation stays the manufacturer's and an administrator submits it.
Read the repair order as written — the concern, the technician's story, the parts, the sublet and the time punches.
02
Pull the vehicle's own record — in-service date, odometer at write-up, terms and campaigns open against the VIN.
Reason
03
Match the story to the manufacturer's published labour operation and the allowance already set against it.
04
Read the narrative for the concern, the cause and the correction the manufacturer's procedure asks for.
05
Check parts, sublet invoices and prior-approval numbers against what that operation is meant to carry.
Decide
06
Hold a file where the documentation, the coverage or the authorisation would not stand up in an audit.
07
Route added operations, straight time and repeat visits to the service manager who has to approve them.
Out
08
Present a claim file with the gaps named, for a warranty administrator to correct and submit.
09
Keep the repair order as it arrived, the gaps raised and every correction the administrator made.
→Product statement
The agent assembles and checks. The labour operation and its allowance belong to the manufacturer, the submission carries a named administrator, and coverage is the manufacturer's to decide.
Example workflow
One repair order, end to end
AgentHuman
1Repair order closedA warranty-flagged repair order arrives from the DMS with its lines, parts, sublet and time punches
2Vehicle and coverage readVIN, in-service date, odometer at write-up, the terms that apply and the campaigns open on that vehicle
3Story matched to an operationThe technician's words matched to a published labour operation and the allowance it already carries
4Documentation checkedConcern, cause and correction, the signed authorisation, parts retention, sublet and any prior approval
No human action required
Stages 1 to 4 run without a person in the loop — the coverage read, the operation match and the documentation check all finish before anyone is asked to look. Nothing has left the dealership at the end of them.
5DecisionSplits on whether the file would hold up if it were audited
File would hold up
Reaches the administrator ready to check and send.
File would not hold up
Held with the gap named, for a person to close.
Warranty administrator
Reads the repair order against the operation, the allowance and the coverage, closes the gaps and submits the claim under their own name.

Warranty-flagged repair ordersClosed in your DMS
03Match & check
Read from the published guide
Use the labour operations as the manufacturer publishes them, the allowance already set against each, the terms that apply and the campaigns open on that VIN.
01Approved path
Stop rebuilding the claim by hand
The operation, the parts, the punches and the coverage arrive already assembled, so the administrator starts from a file instead of a repair order.
02Human review
Find the gap before the auditor does
A missing cause line, an unsigned authorisation or a part nobody kept is raised while the vehicle is still on site, not at the audit two years on.
04Build an evidence trail
Retain the repair order as written, the operation matched, the terms read, the gaps raised, the administrator's edits and what the manufacturer paid — on both paths.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls
Six layers between the model and the claim you submit
Each control wraps the one inside it. A file clears every layer before an administrator sees it, and none of them adds an hour the manufacturer has not published.

How Nestack evaluates it
Evaluate the whole claim file — not only the operation it matched.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Failure modes
Where each failure originates in the agent
Seven failure modes plotted against the five stages of the agent lifecycle. None of them submits a claim — the administrator's check and the manufacturer's own adjudication are the controls that stop them.

A new platform is what the guide has least to say about
A first-year platform changes its operations and allowances faster than anything the agent has read, and a high-voltage repair may have almost no comparable history behind it. Nestack reports performance by slice, not only in total.

Evidence-linked improvement
A debit in March scores a claim from November
Every file an administrator had to correct, and every line the manufacturer later took back, is scored again against what the agent put in front of them at the time.
