Scope

Retail & E-commerce AI agents we build & manage

Twenty-three archetypes — from order status and agentic checkout to product-safety reporting, import evidence and escheatment.

Observability

What we make observable

Every retail and e-commerce agent session is traced across ten layers — what we capture and the evidence we keep.

Failure modes

Filter failure modes by where they occur in the agent lifecycle—from goals and retrieval to tools, evaluations, guardrails and outcomes.

Nothing on this page matches that. Try a layer (tool, retrieval, guardrail), a code, or a severity.

Guardrails

Critical guardrails for Retail & e-commerce agents

Ten controls that hold regardless of prompt, plan or pressure. Open one to see what it protects, what trips it, what the agent is forced to do, who may release it, and what is written to the record.

GR-01No refund or credit above policy ceilingOverride defined
  1. Target

    Refund, credit, goodwill and waiver actions across storefront, marketplace and contact-centre channels

  2. Trigger

    Requested amount or concession exceeds the authorised ceiling for this customer tier and order

  3. Action — enforced

    Platform holds the transaction and routes it to a supervisor queue; agent may still quote published policy

  4. Human override

    CX supervisor releases the hold in the case-management console with recorded justification

Logged evidenceorder id · customer id · requested vs ceiling amount · policy version · approver identity · UTC timestamp

GR-02No price or promotion published outside approved guard bandsOverride defined
  1. Target

    Repricer output, promotion stacking and electronic shelf-label pushes across web, app and in-store channels

  2. Trigger

    Proposed price breaches the floor-to-ceiling band, undercuts cost basis or stacks discounts beyond configured depth

  3. Action — enforced

    Platform blocks publication and reverts to the last approved price; agent may submit the change for merchandising review

  4. Human override

    Merchandising lead approves out-of-band changes in the pricing console with dual sign-off

Logged evidenceSKU · proposed vs approved price · band version · triggering rule id · channel · UTC timestamp

GR-03No cross-customer retrieval in any sessionNo override
  1. Target

    Order history, loyalty balances, saved payment tokens and promo eligibility across all customer accounts

  2. Trigger

    Any retrieval or tool call references an identifier outside the authenticated session’s account scope

  3. Action — enforced

    Platform denies the call and strips the foreign record from context; agent may serve only the verified account

  4. Human override

    None — cannot be overridden in session

Logged evidencesession id · authenticated customer id · blocked identifier · denied query hash · policy version · UTC timestamp

GR-04No instruction embedded in reviews, order notes or images executedNo override
  1. Target

    Product reviews, order notes, seller messages, uploaded images and scraped listings entering agent context

  2. Trigger

    Ingested content carries imperative phrasing, tool-call syntax or links steering agent behaviour

  3. Action — enforced

    Platform quarantines the artifact and processes it as inert data; agent may summarise it but never obey it

  4. Human override

    None — cannot be overridden in session

Logged evidenceartifact id · source channel · matched pattern class · content hash · session id · UTC timestamp

GR-05No raw card data in model context or logsOverride defined
  1. Target

    Chat transcripts, voice transcriptions, tool payloads, agent memory and observability pipelines platform-wide

  2. Trigger

    PAN, CVV or wallet-credential pattern detected in any prompt, completion or log stream

  3. Action — enforced

    Platform redacts to a vault token before persistence and blocks the turn; agent may reference last-four digits only

  4. Human override

    Payments security officer adjusts detection rules via PCI change-control ticket

Logged evidenceredaction event id · pattern class · vault token reference · channel · ruleset version · UTC timestamp

GR-06No age-restricted item sold without verified ageOverride defined
  1. Target

    Checkout, substitution and click-and-collect flows for alcohol, blades, medicines and other age-gated lines

  2. Trigger

    Basket contains an age-gated SKU with no valid verification token for this order

  3. Action — enforced

    Platform blocks sale and substitution of that line; agent may start the verification flow or remove the item

  4. Human override

    Compliance manager releases a single order after a documented manual ID check

Logged evidenceSKU · order id · verification token status · jurisdiction ruleset version · final disposition · UTC timestamp

GR-07No recalled or safety-flagged item recommended or soldOverride defined
  1. Target

    Search, recommendations, substitutions and replenishment actions across the entire catalog and marketplace

  2. Trigger

    SKU or listing matches the synced recall and safety-hold register at decision time

  3. Action — enforced

    Platform suppresses the item everywhere and cancels pending replenishment; agent may state recall status and remedy steps

  4. Human override

    Product-safety lead clears the register entry after documented regulator clearance

Logged evidenceSKU · recall register version · suppression scope · blocked action type · clearing authority · UTC timestamp

GR-08No account or payout change on voice match aloneOverride defined
  1. Target

    Contact-centre changes to addresses, payout details, credentials and high-value order placement

  2. Trigger

    Sensitive change requested with only voice, caller ID or chat assertion as identity proof

  3. Action — enforced

    Platform forces confirmation on the registered out-of-band channel before executing; agent may stage the change meanwhile

  4. Human override

    Fraud-operations lead approves through the step-up identity workflow with documented checks

Logged evidencecase id · requested change · liveness score · out-of-band confirmation id · approver identity · UTC timestamp

GR-09No theft accusation issued on model output aloneOverride defined
  1. Target

    Computer-vision loss-prevention alerts and cashierless checkout attribution across all store estates

  2. Trigger

    A vision or attribution model flags a shopper for suspected theft or unpaid items

  3. Action — enforced

    Platform holds the alert for trained staff review; agent may never confront, accuse or bill the shopper

  4. Human override

    Loss-prevention supervisor confirms with corroborating footage in the case-review tool

Logged evidencealert id · camera and model versions · confidence score · reviewer identity · final disposition · UTC timestamp

GR-10No seller suspension or fund freeze without human adjudicationOverride defined
  1. Target

    Marketplace enforcement: listing takedowns, seller suspensions and payout freezes on third-party accounts

  2. Trigger

    An automated enforcement model recommends suspension, takedown or fund freeze against a seller

  3. Action — enforced

    Platform stages the action pending adjudication; agent may assemble the evidence bundle and notify the seller of review

  4. Human override

    Marketplace integrity manager executes after documented adjudication in the enforcement console

Logged evidenceseller id · model rationale · evidence bundle hash · adjudicator identity · decision · UTC timestamp

Oversight

Human review — triggers, decisions and evidence

When a defined risk trigger fires, the affected action is routed to a named reviewer. Every decision is recorded with its correction, escalation and final outcome for full traceability.

Pricing & advertising claims

Deceptive acts are unlawful whoever drafts them. A former price must have been openly offered recently; environmental and health claims need qualification, so generated copy that escalates or generalises a claim binds the merchant.

  1. Domain-expert review

    Client-designated subject-matter experts review evaluation criteria, pass thresholds and industry-specific risks before baseline approval.

  2. Test-case rotation

    Evaluation cases are refreshed regularly to reduce memorisation, limit overfitting and maintain meaningful performance measurement.

  3. Scorecard integration

    Scorecards compare results with the approved baseline, show performance trends and flag material declines for review and escalation.

  4. Client-specific extensions

    Where included in scope, evaluations may be expanded using approved incidents, workflows, policies, data patterns and industry-specific risks.

Monitoring

Change-aware monitoring

When agent performance changes, Nestack correlates the shift with changes to the agent, prompt, model, tools, knowledge base, guardrails and evaluation suite.

Severity is assigned based on business impact, customer harm, data exposure, operational disruption and overall scope.

  • SEV-1 Critical
  • SEV-2 Major
  • SEV-3 Moderate
  • SEV-4 Minor
STEP 01

Automated monitoring or human review identifies unusual behaviour. Alerts are recorded and routed according to severity.

Outcomes

Not just that it ran.

Cost control

Keep retail & e-commerce AI agent costs under control

Token spend is monitored, optimised and reported as part of Agent Care — and savings never come at the expense of quality, because every change is verified against your evaluation baseline.

We review token spend by agent, workflow, model, and session so you can understand where AI costs are coming from.
