What this agent does

Ranks inside your catalogue; the shopper buys

In
01

Catalogue records, price cards, stock and configured review rules, ingested from supported commerce or PIM sources.

02

Attribute names and units normalised, with each value carried forward from the record it came from.

Reason
03

A shortlist drawn from the catalogue, ranked on the attributes the shopper asked about.

04

Brand, market and category rules applied as the merchant configured them.

05

Comparisons built from attributes on the product card, with what the card leaves out marked as missing.

Decide
06

Review content surfaced under the merchant's configured handling rules.

07

An AI-system disclosure and any material connection shown in the session.

Out
08

The recommendation, the attributes behind it and the shopper's authorisation retained together.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent recommends and assembles; the shopper authorises the purchase, and the merchant of record still carries fraud and chargebacks.

Example workflow

One session, request to purchase

4Controls appliedCatalogue-source checks, review-handling rules, disclosure checks and the confidence threshold
No human action required

Stages 1 to 4 run unaided and nothing is bought at any of them — the agent is recommending, and the shopper's lane opens at the confidence gate.

5DecisionSplits at the confidence threshold
High confidence

Goes to the shopper to authorise.

Low confidence

Adds a commerce-team check first.

Shopper authorisation

The basket is held with the attributes behind it, the total and the confidence.

Authorise · Amend · Hand to a person
Authorised — order placed

7Outcome evaluatedDisowned orders, returns, cancellations and corrections made after the order shipped
Amends

Each shopper amendment is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items
Completing a purchase or authorising a payment.
Enrolling a subscription, trial or auto-renewal.
Generating review content outside the configured rules.
Quoting a price that is not on the published card.
Automation boundaryAgent acts unaided
Search the configured catalogue and rank what matches the request.
Compare candidates on attributes held in the catalogue.
Assemble a basket and leave it with the shopper.
Hold the order and put an itemised authorisation to the shopper.
Any write happens inside the boundaries agreed at implementation, never ahead of authorisation.
Accepting merchant terms for the shopper.
Applying an eco, efficiency or certification label.
Trading where the platform's terms bar agents.
Changes to disclosure or recommendation rules.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every sessionFrom the storefront
03Ranking

Rank inside the card

Draw on the attributes published on the card and the merchant's configured rules.

01Approved path

Recommend inside the catalogue

Routine product questions are answered from the catalogue itself.

02Human review

Push the risky calls to a person

Purchases and subscriptions are held for the shopper, because whether a wrong one is unauthorised is unsettled.

04Build an evidence trail

The recommendation, the attributes it rested on and the authorisation for any purchase stay on the session.

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 checkout

The controls are nested. What survives all of them appears in the map underneath.

How Nestack evaluates it

Evaluate the whole session — not only the product that came top.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — what the shopper is shown
Depth of coverage ▼
E1Final-output evaluationDid each attribute the agent stated match the card?
E2Step-level evaluationDid the agent use the right catalogue, review rules and disclosure set?

Affected slices

The average hides where this concentrates

In aggregate the disowned-order rate looks settled; by slice, a few session types carry most of it. Nestack reports the disowned-order rate by cohort, not only in total.

Evidence-linked improvement

A cycle ends with a standing test

Explaining a bad recommendation does not close the cycle. A standing regression case does, and that suite is what the next session is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Disowned orders rise in one session slice.

02Diagnose

The named commerce owner opens the sessions and the cards behind them until one cause holds.

03Improve

The fix is versioned against the sessions that produced it.

04Verify

The release stops until every affected case is passing.

05Learn

The case stays in the suite, and the recommendation policy is amended.

Learn → DetectThe return edge. What comes next is measured against a longer suite.

Typical build scope

Twelve workstreams across six weeks

The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, recommendation workflow, evaluation, integration, then production validation and handover.

Next step · Electronics AI agent

Build a commerce agent around an authorisation you can produce.

Show us your catalogue, your disclosure rules and who owns them. If you cannot yet show what a shopper authorised, we start there — that question is unsettled.
