Answer product, stock and procedure questions on the floor, draft a task or shift change with the predictability premium already computed, and hold it for the store manager who publishes.
Normalise each store's calendar against the notice window and premium rules its own jurisdiction sets.
Reason
03
Answer product location, price, stock-on-hand and procedure questions from the current record.
04
Sequence the tasks already assigned to a shift by aisle and by the store's own layout.
05
Draft a task or shift change and compute the predictability premium it would trigger.
Decide
06
Flag any change falling inside a notice window, and leave who initiated it to a person.
07
Route every proposed change to the store manager, and stop at the clock-out boundary.
Out
08
Retain the proposal, the premium computed, the approver and what the change displaced.
09
Execute write actions only inside the approval boundaries agreed during implementation.
→Product statement
The agent proposes; the store manager publishes the change, and the employer stays answerable for the posted schedule.

No human action required
Every stage before the confidence gate runs unaided, and nothing is published at any of them — the agent is drafting, and the manager's lane opens at the gate.

Qualified and free

Adds a district-manager read first.
Manager approval
The proposal is held with its premium, its flagged lines and the confidence.

Publishing, moving, shortening or cancelling a posted shift.
Classifying a change as employee-initiated.
Waiving or reducing a predictability premium.

✓Answer product location, price.
✓Serve the current standard-operating-procedure text for the named owner.
✓Sequence a shift's already-assigned tasks by store.
✓Draft a change proposal with the premium pre-computed and flagged.
Any write happens inside the boundaries agreed at implementation, never ahead of the manager's approval.

How Nestack evaluates it
Evaluate the whole assignment path — not only the answer on the handset.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — what the associate is told

E1Final-output evaluationDid the proposal fall inside a notice window, and was the premium computed against it?
E2Step-level evaluationDid the agent read the live schedule, the right jurisdiction rules and the accommodation register?
E3Tool evaluationDid it write to the correct store, the correct shift and the correct system?
E4Confidence calibrationDo low-confidence proposals actually attract more manager amendments?
E5Slice evaluationHow does performance change across specific associate cohorts?

Failure modes
Where each failure originates in the agent
Seven modes, each at the stage it begins.

Evidence-linked improvement
The cycle ends inside the suite
Closing is a test being added, not a meeting being held about the failure That suite is what the following detection is measured against..
Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect
Window breaches rise in one associate cohort.
02Diagnose
The store manager walks the shift records behind each breach until the cause narrows to one.
03Improve
A version, an owner and the shift records that prompted it, together.
04Verify
Affected cases must clear before the change reaches the floor.
05Learn
A standing case, and a change to how tasks are assigned.
Learn → DetectThe return edge. Detection next time is measured against a suite this cycle made longer.

Build a store-associate agent around the manager who publishes the schedule.
Show us your store formats, your workforce systems and who publishes a schedule. If your stores sit in a fair-workweek jurisdiction, the notice window is the first thing we map, because a change made inside it is already an obligation before anyone has reviewed it.
