Scope

Operations AI agents we build & manage

Thirteen archetypes — from SOPs to process mining, orchestration and KPI-anomaly detection.

Observability

What we make observable

Every operations agent session is traced across ten layers — what we capture and the evidence we keep.

Guardrails

Critical guardrails for Operations 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 improvised steps outside the controlled SOP corpusOverride defined
  1. Target

    Process guidance, safety steps and work instructions served to operators and downstream agents

  2. Trigger

    Any procedural answer not traceable to a controlled-document id and current revision

  3. Action — enforced

    Platform refuses the answer and cites the gap; agent may only quote controlled documents verbatim

  4. Human override

    Quality manager issues an interim instruction via the controlled-document deviation process

Logged evidencedocument id · revision · refused answer text · requester · timestamp

GR-02No cross-site parameter transfer between facilitiesNo override
  1. Target

    Site-specific process parameters, limits and procedures across all plants and facilities

  2. Trigger

    Any retrieval or write applying one site’s parameters, limits or procedures at another site

  3. Action — enforced

    Platform denies the operation at the index layer; agent works only from the active site’s corpus

  4. Human override

    None — cannot be overridden in session

Logged evidencesite ids · denied parameter set · index scope version · requesting agent · timestamp

GR-03No instruction embedded in vendor documents or emails ever executedNo override
  1. Target

    Inbound vendor emails, work orders, invoices, delivery notes and scanned operational records

  2. Trigger

    Imperative or tool-directed language detected inside any externally sourced document under processing

  3. Action — enforced

    Platform strips and quarantines the instruction; agent treats the content as inert data, never as commands

  4. Human override

    None — cannot be overridden in session

Logged evidencedocument hash · quarantined instruction · detection rule id · sender · timestamp

GR-04No auto-closure of safety-critical incident signalsOverride defined
  1. Target

    Incident queues, outage alerts and safety-event feeds across monitored operational systems

  2. Trigger

    Any downgrade, closure or summary omission touching an incident tagged safety-critical

  3. Action — enforced

    Platform forces escalation to the on-call human chain and blocks closure; agent may only append evidence

  4. Human override

    Site safety officer closes personally after documented investigation in the incident system

Logged evidenceincident id · severity tag · escalation chain · blocking event · closer identity · timestamp

GR-05No execution without the required sign-off chainOverride defined
  1. Target

    Operational actions gated by approval workflows across ERP, WMS and scheduling systems

  2. Trigger

    Any action request missing a sign-off, or approvals arriving faster than review-time floors

  3. Action — enforced

    Platform holds the action and re-queues slow-path review; agent may only resubmit with complete approvals

  4. Human override

    Process owner releases via the approval workflow with each approver re-confirmed

Logged evidenceaction id · approval chain state · per-approver timestamps · review durations · release id

GR-06No work scheduled into blackout windowsOverride defined
  1. Target

    Change calendars, maintenance schedules and dispatch plans across sites and shared systems

  2. Trigger

    Proposed work intersecting a published blackout, freeze or peak-load window for the asset

  3. Action — enforced

    Platform blocks the booking and proposes compliant slots; agent may request a window exception

  4. Human override

    Change-advisory board approves an exception via the change-management record

Logged evidencechange id · window definition · conflict detail · CAB decision id · timestamp

GR-07No duplicate work-order issue on retry or timeoutOverride defined
  1. Target

    Work-order creation, dispatch and purchasing calls across ERP, WMS and field systems

  2. Trigger

    Retry, timeout or loop re-invoking an action whose idempotency key already has a result

  3. Action — enforced

    Platform returns the original result and halts looping jobs; agent reports the retry cause upstream

  4. Human override

    Operations supervisor re-issues intentionally via a new keyed request after ledger check

Logged evidenceidempotency key · original result id · retry count · halted job id · timestamp

GR-08No completion report without machine-verifiable evidenceOverride defined
  1. Target

    Task-completion claims and status reports written back to systems of record

  2. Trigger

    A done status lacking the linked system evidence that the work actually executed

  3. Action — enforced

    Platform marks the task unverified and blocks downstream dependencies; agent must attach evidence or escalate

  4. Human override

    Shift supervisor accepts with manual verification recorded against the task

Logged evidencetask id · claimed status · evidence link or absence · verifier · timestamp

GR-09No execution from a stale system snapshotOverride defined
  1. Target

    State reads feeding writes across ERP, scheduling, inventory and ticketing systems

  2. Trigger

    Snapshot older than the freshness ceiling or a newer conflicting update detected pre-write

  3. Action — enforced

    Platform refreshes state and re-plans before writing; conflicting writes are held for human merge

  4. Human override

    Data steward forces the write after documented conflict review in the change log

Logged evidencesnapshot age · conflict record ids · before/after state · decision · timestamp

GR-10No vendor commitment beyond delegated authority limitsOverride defined
  1. Target

    Vendor emails, portals and contract channels where agents draft or send commitments

  2. Trigger

    Any message or document that would commit spend, terms or schedule beyond the agent’s mandate

  3. Action — enforced

    Platform blocks the outbound commitment; agent may send information-only replies flagged as non-binding

  4. Human override

    Budget holder countersigns via the delegation-of-authority workflow before release

Logged evidencedraft hash · commitment terms · authority limit · countersigner · release 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.

Use your work email to unlock the full grid. We use it to send the requested Agent Care material and qualify business inquiries. We do not sell or share your email.

  1. Department lead review

    For applicable high-risk agents, the client’s designated department leader reviews the evaluation criteria and pass thresholds before baseline approval.

  2. Test-case rotation

    Evaluation cases are refreshed regularly to reduce memorisation and maintain reliable performance measurement.

  3. Scorecard integration

    Scorecards track results against the approved baseline and flag material declines for review and escalation.

  4. Department-specific extensions

    Where included in scope, evaluations may be expanded using approved workflows, tools, templates, policies, and incident history.

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.

Universal incident runbook

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.

Cost control

Keep operations 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.
