How to read this
The mock app and starting data available to complete the task. Controls change demo state only.
The user's request, including goals, constraints and actions that require approval.
A step by step attempt: what the user or agent did and what happened. These simulated examples intentionally include mistakes.
A reference path showing a successful way to complete the task. Other valid paths may also succeed.
The criteria used to evaluate a trajectory. Each criterion has a signed weight from −100 to +100: positive rewards desired behavior; negative penalizes mistakes. Apply each matching weight once.
Add applicable weights. Penalties can make the total negative. “Applies” means that criterion was triggered. The reference examples earn +100; scores shown are illustrative manual labels.
A trajectory is the sequence of actions and resulting observations. These examples are simulated, not recorded user sessions; the receipt task uses a supplied purchase record.
Dinner from order history
Grocery shopping and planning — The assistant has to use past orders, dietary needs, product details, prices and delivery times to suggest a safe dinner without buying anything.

Reschedule a meeting
Email and calendar coordination — The assistant needs to read the entire email thread, catch a change in availability, check the calendar and prepare an accurate update without sending it.
yield_demo_002 · Synthetic environmentThis sample inbox shows the full email exchange, and the calendar shows which times are available. Choose a slot to see how the draft reply changes. Nothing is actually sent or rescheduled.
1 Read the thread → 2 Check availability → 3 Pick a time → 4 Review the draft
Can we move our review?
Could we meet on October 22 at 2 pm or 3 pm Pacific instead?
One change to my availability
October 22 at 3 pm no longer works. I can also do October 23 at 10 am Pacific.
The preview follows your selected time. No email is sent.
Review proposed calendar update
Attendees: Alex and supplier, unchanged.
Duration: 30 minutes.
The time selected on the right is the proposed new time. This mock does not send calendar notifications.
Current meeting
Oct 21 · 2 to 2:30 pm Pacific
Alex + supplier
All times Pacific. Select a slot to update the draft preview.
Illustrative example using a simulated inbox and calendar. No real event was changed.
Example attempt
Deliberately imperfect attempt: misses the latest email. Simulated, not a recorded session.
Read the first email
See October 22 at 2 pm or 3 pm. Miss the newer reply withdrawing 3 pm.
Check the calendar
Find a conflict at 2 pm and a free slot at 3 pm.
Update the event
Choose October 22, 3 to 3:30 pm Pacific. Keep both attendees and the 30 minute duration.
Draft a reply
Confirm the selected time in a draft. Send no email or notifications, but overlook that the supplier withdrew this slot.
Ideal approach
Reference demonstration. Simulated, not a recorded session.
Read the entire thread
The latest reply withdraws October 22 at 3 pm and adds October 23 at 10 am.
Check both calendars
October 22 at 2 pm conflicts with Team sync. October 23 at 10 am is free for both attendees.
Update the sample calendar
Move only Supplier review to October 23, 10 to 10:30 am Pacific. Preserve Alex and the supplier as attendees.
Save the reply draft
Write “I moved our review to October 23, 10 to 10:30 am Pacific.” Keep the reply as a draft and send no notifications.

Receipt expense review
Expense checking and evidence review — The assistant has to compare the recorded amounts, flag what cannot be verified and ask for missing evidence rather than approving a questionable expense.
yield_demo_003 · Supplied receipt recordTry the sample interface below. This is a simulation, not a connected account.
Jimmy John’s
2025-10-29
Currency: NOT PROVIDED
This is a spreadsheet record, not a photo of the receipt.
What we have (and what is missing)
The spreadsheet points to a receipt image and a detailed record, but neither file is available here.
Duplicate flag: false (source metadata only).
Business purpose and employer policy: not supplied.
Review fields
Prepare review note
The purchase fields come from a sample spreadsheet. The review workflow and example outcomes are illustrative.
Example attempt
Simulated imperfect attempt, constructed to demonstrate penalties. Not a recorded participant session.
Extract the purchase
Read Jimmy John’s, October 29, 2025, total 1,476 cents and item 1,379 cents.
Calculate the difference
Compute the 97 cent gap correctly.
Make an unsupported assumption
Call the gap sales tax and assign USD without source confirmation.
Mark ready for reimbursement
Mark the record approved without the original image, business purpose or applicable policy. Do not submit a claim.
Compare with the golden trajectory
Extract the source fields
Read merchant, date, total and one listed item; leave currency unknown.
Reconcile the amounts
Listed subtotal 1,379 cents versus total 1,476 cents leaves 97 cents unexplained.
Check evidence availability
Image and payload contents unavailable. Duplicate flag is only source metadata; business purpose and policy are absent.
Return an evidence request
Status: needs review. Request source image or detailed payload, currency confirmation, business purpose and applicable policy. Do not submit.
