What this agent does

Publishes a comparison, not an accuracy claim

In

  1. 01

    Ingest sales history, prices, promotion calendars and event dates from planning, ERP or POS sources.

  2. 02

    Normalise item, store and calendar fields, and carry each series forward with its own history.

Reason

  1. 03

    Forecast at the item-store level the ordering decision is made at, not only in aggregate.

  2. 04

    Run the naive and seasonal-naive baselines alongside, on the same holdout, over the same period.

  3. 05

    Report the forecast beside those baselines, so the comparison is one a planner can re-run.

Decide

  1. 06

    Flag new products and promotional periods as regimes the forecast does not cover.

  2. 07

    Route every forecast to the named demand planner, who decides what enters the plan.

Out

  1. 08

    Retain the history, the baseline run, the planner's overrides and the forecast accepted.

  2. 09

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

Product statement

The agent proposes a forecast against a benchmark; the demand planner accepts it into the plan, and ordering, promotion and production stay separate decisions.

Example workflow

One item, history to accepted forecast

  1. 1History receivedPOS, ERP or planning-system history, prices and the promotion calendar
  2. 2Context assembledPrice, promotion, event and calendar features, each with the series it belongs to
  3. 3Forecast producedForecast, baseline run, horizon, confidence
  4. 4Controls appliedHoldout checks against the naive and seasonal-naive baselines, regime flags and confidence threshold

No human action required

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

5DecisionBranches at the confidence threshold
High confidence

Goes to the demand planner to accept.

Low confidence

Falls back to the naive baseline first.

Planner acceptance

The forecast is held with its history, its baseline run and the confidence.

Accept · Adjust · Send to demand review

Accepted — released to the plan

  1. 6Planning systems updatedOnly where write access and approval policy allow it
  2. 7Outcome evaluatedError against the stated baseline, override rates, regime flags and what the plan needed

Overrides

Every planner override is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required

8 items

  • Placing or releasing an order from a forecast.
    • Committing production volume or raw-material buys.
    • Setting a promotional price, depth or mechanic.
    • Publishing an accuracy claim about its own output.

  • Automation boundary

    Agent acts unaided

    • ✓Forecast each series at the level the ordering decision is made.
    • ✓Run the simple benchmarks beside it, on one shared holdout.
    • ✓Report the horizon, the metric and the comparison together.
    • ✓Mark the regimes it does not cover, and hold for the planner.

    Any write happens inside the boundaries agreed at implementation, never ahead of acceptance.

    • Deciding what a new product will sell in week one.
    • Judging whether a promotion should run at all.
    • Changing the benchmark a forecast is measured against.
  • Changes to features, thresholds or acceptance rules.

Example output

One item forecast, annotated

Everything the agent forecasts is attached to the history it was drawn from.

Forecast output · single item-store

Illustrative example
Item
Chilled line, one store
What was forecast
Weekly units for a chilled line at a single store
Horizon
Four weeks out
Benchmark run beside it
Seasonal naive, same holdout
Confidence

Error metric
Weighted absolute error

As received

Taken from the item's own sales history and the customer's promotion calendar.

Source history used

  • Item sales history
  • Promotion calendar
  • Naive baseline run

Why no accuracy figure

A regulator has ordered relief over a stated AI accuracy claim; a benchmark you can.

What the score decides

Below the configured threshold the forecast falls back to the naive baseline before.

Action

AcceptAdjustSend to demand review

Value

Where AI adds value

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

Where the value lands

Value 01 – 04

Every item

From the item's own history

03Forecasting

Forecast against a benchmark

Draw on the sales history, the price and promotion calendar, and the simple methods the forecast has to beat.

01Approved path

Forecast it, own the error

Routine item-store forecasts arrive already published beside their benchmark.

02Human review

Send the planner where it is weak

Regime flags and low-confidence forecasts are marked, so the planner's read starts where the model is weakest.

04

Build an evidence trail

The forecast, the history behind it and the planner who accepted it stay on the item record.

Agent controls

Six layers between the model and the plan

Each control encloses the last. Whatever slips past all of them is named below.

How Nestack evaluates it

Evaluate the forecasting workflow — not only the number at the end.

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

Surface — the forecast the plan sees

  1. E1Final-output evaluationDid the forecast beat its stated benchmark on the same holdout?
  2. E2Step-level evaluationDid the agent use the right history, calendar and feature set?
  3. E3Tool evaluationDid it read and write the correct item and the correct store?
  4. E4Confidence calibrationDo low-confidence forecasts actually attract more planner overrides?
  5. E5Slice evaluationHow does performance change across specific item groups?
  6. E6Business outcomeHow many forecasts needed an override, or missed what the plan needed?

Failure modes

Where each failure originates in the agent

Seven ways a forecast goes wrong, placed by stage.

Agent lifecycle

Direction of processing →

  1. 01 · Retrieval

    1 mode

    • BL-03

      Superseded history read

      A restated sales series is read as though it were current.

    Stage gathers

    Sales history, prices, promotions and event dates

  2. 02 · Reasoning

    2 modes

    • BL-04

      Promotion read as normal

      A promoted week is forecast as though it were ordinary trading.

    • BL-06

      New product proxied

      An item with no history is forecast from a proxy nobody chose.

    Stage proposes

    Forecast, baseline run, regime flags and confidence

  3. 03 · Tool / write

    2 modes

    • BL-02

      Ordered before acceptance

      A forecast reaches an order before a planner accepted it.

    • BL-05

      Duplicate series

      One item-store series is forecast twice from two sources.

    Stage writes

    Only where write access and approval policy allow it

  4. 04 · Output

    1 mode

    • BL-01

      Beaten by the baseline

      The forecast is worse than the simple method beside it.

    Stage returns

    The forecast the planner accepts into the plan

  5. 05 · Change / Version

    1 mode

    • BL-07

      Silent error regression

      A model or feature change widens the error unannounced.

    Stage tracks

    Model, prompt, feature sets and horizon config

  • Sev-1 · an order ran off a forecast
  • Sev-2 · the baseline beat the forecast
  • Sev-3 · history degrades, forecast to review

Affected slices

Overall error can hide one bad cohort

Aggregate override rates can look acceptable while a few item cohorts absorb most of the rework. Nestack reports the planner-override rate by slice, not only in total.

Slice performance — reported separately, not only in aggregate

Evidence-linked improvement

The loop ends in a test, not a review

The cycle does not end in a post-mortem. It ends in a case the next release has to clear, and that suite is what the next forecast issued is measured against.

Improvement cycle · five stages

Switchback — the path turns at Improve and returns at Learn

  1. 01

    Detect

    Override rate rises in an item slice.

  2. 02

    Diagnose

    The forecasts come out first — the series, the benchmark run beside each one and the overrides on top — and are read until the cause narrows to one.

  3. 03

    Improve

    Each change carries a version and the forecasts that forced it.

  4. 04

    Verify

    Release waits on the affected cases going green again.

  5. 05

    Learn

    The case is kept for good, and the planning rules are rewritten.

  6. Learn → Detect

    The return edge. The next forecast meets a suite one case longer.
