Problem and commercial diagnosis
The unit of value is a better operating decision, not an AI interaction.
Score seller and listing risk, monitor service evidence and route disputes without replacing policy or investigator judgment. The business problem exists because evidence and action are separated across teams and systems. People spend time finding the current fact, reconciling conflicting records and deciding which policy applies before they can address the commercial or service issue.
The management question is: Which seller, offer or order needs review, what evidence supports the concern, and what action is permitted? That question defines the workflow boundary. It also prevents a broad AI programme from becoming a collection of demonstrations without an owner, a cost baseline or an operating result.
The commercial diagnosis starts with the present cost of delay, rework, leakage or missed opportunity. It records case volume, handling time, error, exception age, customer or partner consequence and the contribution affected. Benefits are modeled against that baseline and replaced by realized evidence only after a controlled deployment.
This case is a modern operating design. It does not imply that the workflow was historically deployed, that a named enterprise uses it or that modeled impact has been achieved.
Put the agent inside the workflow, with an owner on both sides.
The business owner defines the outcome, priority logic and economic guardrails. Operations owns the day-to-day queue, service level and exception resolution. Technology owns reliable interfaces, identity, observability and rollback. Data and control owners approve purpose, source access, retention, evaluation and consequential tool permissions.
The workflow should begin in read-only mode. The agent identifies the case, retrieves evidence and prepares a recommendation. Reviewers compare it with the source records and label the result. Once accuracy, failure modes and economic value are understood, the team can permit selected low-risk tools. Higher-consequence actions remain approval-gated.
A shared case record keeps the input, policy, source references, model version, recommendation, reviewer decision, action and outcome together. This makes disputes and audits easier, and it creates the evaluation set needed to improve the system without silently changing behavior.

Specialist tasks, one controlled state machine.
The intake agent identifies the task and required records. A retrieval or evidence agent gathers approved knowledge and live facts. An analytical agent compares those facts with rules, thresholds or models. A recommendation agent explains the permitted options and their expected operational or commercial effect. A workflow agent routes approval and invokes a named tool only when authorization is present.
The specific workflow steps are tailored to this case: Detect listing-quality gaps; Flag unusual seller and order patterns; Monitor service-level breaches; Assemble dispute evidence; Recommend a proportionate review route. Each step has a deterministic input and completion state even where a probabilistic model helps interpret the evidence. A confidence score never replaces missing authority or a required source record.
Exception handling is part of the design. Missing data, conflicting records, low confidence, policy ambiguity and tool failure move to a person with the evidence already assembled. The system should fail closed for money, customer rights, safety, regulated decisions and material partner consequences.
Review required
Rank permitted options and show the assumptions, confidence and trade-offs.
Bounded permission
Use a named tool within value, role, policy and rollback limits.
Knowledge, live facts, workflow state and authority stay separate.
The architecture begins with enterprise identity and role-based access. Retrieval-augmented generation supplies approved policies, procedures and reference knowledge. APIs supply facts that change, such as stock, price, order state, payment, account status or capacity. An event layer signals that something changed and a workflow store records the case state.
The authoritative sources for this operating case are Verified seller identity; Listing and product rights; Orders, delivery and returns; Customer and seller disputes; Policy and enforcement history. Model prompts and vector indexes are not systems of record. Each material answer or recommendation should carry source references and timestamps so a reviewer can see what the system knew when it acted.
A policy and tool gateway checks the user, task, allowed source, action, value threshold and required approval before any write. Observability records latency, cost, tool success, model errors and downstream outcome. Evaluation includes task accuracy and business effect, not only language quality.

Automation capacity is a cost until the business result changes.
Trust investment protects conversion, repeat demand and payment loss while reducing manual review. The model includes false positives, seller friction and the cost of remedies. The baseline should use actual workflow volume, handling effort, defect, leakage, service consequence and decision delay. Modeled impact then applies conservative adoption, accuracy and retained-review assumptions.
The cost model includes integration, data preparation, model use, evaluation, monitoring, support, retained human approval and change management. It also values new failure modes: false positives, poor escalation, incorrect action and the time required to remedy them. The net case is the verified benefit less all of those costs.
KPIs should be read as a linked system: Listing defect rate; Service breach rate; Precision and recall; Dispute cycle time; False-positive rate; Loss avoided; Repeat purchase. Activity metrics such as generated recommendations or tool calls matter only as diagnostic evidence. The operating result and control outcome determine whether authority should expand.

Prove evidence quality before expanding action rights.
Days 0 to 30 establish the workflow baseline, source ownership, authority map, evaluation set and economic equation. The team selects a narrow case family with enough volume to learn and enough reversibility to operate safely. It documents stop conditions before the first model output reaches a user.
Days 30 to 90 connect read-only sources and run recommendations in shadow or assisted mode. Reviewers label correctness, missing evidence and unsafe suggestions. The product team measures cycle time, service outcome, override, model cost and the effect on the real operating queue.
Days 90 to 180 introduce one or two bounded tools with explicit approval and rollback. The sequence for this case is Unify trust taxonomy; Build evidence views; Run models in shadow; Pilot reviewer recommendations; Automate only low-risk routing. Wider data, higher values or unattended action require a fresh gate, not an informal configuration change.
Governance reviews model version, source changes, override patterns, customer or partner harm, access exceptions and realized economics. The system can be scaled, narrowed or paused. A credible AI operating model includes the ability to remove authority when the evidence weakens.
