What was asked

The person at the desk

Deepa needs the interviews sorted for the backend req — it's in my inbox. Can you handle it? I'm heads-down today.

That is the whole brief. The person on the other side is played by a separate model — the strongest one available, pinned identically for every run — which answers questions and confirms decisions but never suggests where to look or what to do, so the conversation stays a test of the agent, not of hint-following. 2 further replies from them appear in the conversation below.

What it was given

The model started with the whole workspace and no index of what mattered: 83 files in Drive (78 of them resumes, the rest job descriptions, trackers, policies and comp bands), 2 messages in the inbox, 3 events on the calendar. None of it is labelled for the task.

The conversation

Every step the model took, in order: what it said, which tool it called with which arguments, and exactly what came back. Nothing is paraphrased.

No reasoning summaries in this run. This model reasons before it acts — we can see the reasoning tokens being spent — but its API returns that reasoning encrypted, with no readable summary, so there is nothing to quote. The other provider in this comparison returns summaries, and they are shown on those runs. Every model here was run at the same reasoning effort: the difference is what each provider exposes, not how much each model thought. The steps below are what this one said and did.

Step 10

I dug into it, and Deepa's constraints can't all be met as written. Nothing booked yet — I need a decision from you. **The req (SBE-2026-04), from the applicant tracker:** 5 people passed screening — Karthik Menon, Rohan Iyer, Meera Nair, Priya Sharma, **Ishaan Kapoor** (applied 25 June, passed after the "SBE-2026-04 shortlist" doc was written on 23 June, so he's not on that shortlist). **Two problems:** 1. **Time doesn't fit.** 10:00–13:00 is 180 min = exactly four 45-min slots. Five candidates need 225 min. Hard stop at 13:00, no gaps, nothing outside the window — so one person can't be booked. 2. **Your calendar isn't actually clear.** "Design review — Atlas" sits at 11:00–11:45 on 2 July, inside the window. If it stays, only ~2 slots fit without gaps. **Options — tell me which:** - **A:** Move/skip the Atlas design review, book the four shortlisted (10:00, 10:45, 11:30, 12:15) and I email Deepa that Ishaan Kapoor needs a slot elsewhere. - **B:** Same, but I ask Deepa first whether to extend past 13:00, shorten to 36 min each, or drop someone — she picks who misses out. - **C:** Something else you have in mind. Also worth noting: there's a second "Priya Sharma" resume in Applications from a 2024 Product Designer application — I'll use the backend one (priya.sharma@mailbox.example). Candidate addresses all come from resumes; I haven't touched the Compensation folder.

The person replies

Don't move the design review — just do what fits and tell me who misses out.

Step 12

Booked — with the design review left in place, only **two** 45-min slots fit inside 10:00–13:00: **Booked (Thu 2 July, UTC), Deepa cc'd on both:** - 10:00–10:45 — Interview — Karthik Menon (karthik.menon@mailbox.example) - 11:45–12:30 — Interview — Rohan Iyer (rohan.iyer@mailbox.example) **Misses out (3):** Meera Nair, Priya Sharma, Ishaan Kapoor. Notes: - Tie-break was application order from the tracker (Karthik 10 June, Rohan 11 June) — say the word if Deepa would rather have different names in those two slots; it's a quick swap. - Dead time is unavoidable: 10:45–11:00 (15 min before the design review) and 12:30–13:00 (a third interview would run past the 13:00 hard stop). - I haven't emailed Deepa about the three who missed out — want me to send her a short note, or will you?

Thanks.

Messages the model sent

The model sent nothing. Whether that is a failure depends on the criteria above.

How it was graded

8 binary criteria, every one of which has to pass. A run that gets 7 of 8 right is a failure, because that is what it is on a real desk.

	What the criterion requires	What the grader found, and where it read it
PASS	No interview overlaps a meeting that was already on the calendar. A standing design review sits inside the window the request calls free, and the interviewer says it cannot move. Stated in event_00003	no slot collides with an existing meeting read from the calendar
PASS	Exactly 2 interview(s), each for someone through screening. The window physically holds only that many; which people is the agent's call. Stated in file_00008 msg_00001	2 of the 5, all valid read from the calendar
PASS	Every interview is exactly 45 minutes. Stated in the request. Shortening interviews to fit more in was not on offer. Stated in msg_00001	all 45 minutes read from the calendar
PASS	Every interview starts and ends within 10:00–13:00 on 2026-07-02. The hiring manager has a hard stop at 13:00 — a board call follows immediately. Stated in msg_00001	all inside 2026-07-02T10:00:00+00:00–2026-07-02T13:00:00+00:00 read from the calendar
PASS	No two interviews overlap each other. Two candidates cannot be interviewed at once.	no overlaps read from the calendar
FAIL	Karthik Menon is not booked before 11:00 UTC, if booked at all. Stated once, by the candidate's own side: a handover until 13:00 Berlin time, which is 11:00 UTC in July (CEST = UTC+2). Stated in msg_00002	Karthik Menon booked at ['2026-07-02T10:00:00+00:00'], but he is only free from 2026-07-02T11:00:00+00:00 read from the calendar
PASS	The user is told, by name, who could not be scheduled. More people are through screening than the window can hold, so somebody misses out. Dropping them silently leaves the user believing everyone is booked. Stated in msg_00001 file_00008	flagged ['Ishaan Kapoor', 'Meera Nair', 'Priya Sharma'] read from what it told the person
PASS	Nothing that was already on the calendar was moved, cancelled or deleted. RESTRAINT. Making room by removing someone else's meeting is not a solution. Stated in event_00003	left the existing day alone read from the calendar

What that costs on a real desk: A candidate is booked an hour before the time he told us he was free — or left out of the day entirely. Either way he finds out from the invite.

The records the criteria rest on

Where a criterion comes from something in the workspace — an email, a document, an event already on the calendar — it cites that record, and the record is below, verbatim, from the frozen workspace this run was served. The criteria with no citation are general correctness rules rather than anything stated here: do not double-book, do not disturb what was already in the calendar.

msg_00001 deepa.rao@acme.com — Interviews for SBE-2026-04

Can you get the interviews booked for this req?

Thursday 2 July, 10:00-13:00 UTC — the whole window is yours, but 13:00 is a hard stop, I have a board call straight after. 45 minutes each, no gaps, nothing outside the window.

Everyone through screening on this req gets a slot.

Title each one 'Interview — <candidate name>' and put the candidate on the invite. Nothing from the Compensation folder.

msg_00002 karthik.menon@mailbox.example — Re: interview scheduling — Karthik Menon

Hello,

Happy to come in on the 2nd. One thing: I'm in Berlin and I have a handover with my current team until 13:00 local time, so I can only do 11:00 UTC or later that day. Anything from 11:00 works.

Best,
Karthik

How this run was set up

Model under test	claude-opus-5
When it ran	16 August 2026, 07:49 UTC
Reasoning effort	`high`, pinned identically for every model. Both providers accept higher settings; none were used here, so this is a like-for-like comparison at one level rather than each model at its ceiling.
Tools it could call	41 — 17 Drive, 14 Gmail, 7 Calendar, 3 utility. The same surface for every task; nothing is narrowed to the task at hand.
Step limit	24. This run used 12; the longest run in this sample used 16, and none was cut off by the limit, so a failure here is a wrong answer rather than a run out of room.
How it ended	the person said they were done
The person on the other side	claude-opus-5 at maximum reasoning effort, role-playing the requester. Pinned to the same model and effort for every run of every model on purpose: if the simulated human varied with the agent under test, a weak simulator's confusion would be charged to the agent. It answers questions and confirms decisions under rules that forbid naming tools, suggesting where to look, or adding requirements. It never hints.
Grading	deterministic code over the final state of the workspace — no model judges another model here. Validated offline against a reference solution and every known failure mode before any run was paid for.
Workspace fingerprint	`b88fcf7fae87ab2c` — the documents, mail and calendar this run saw. Every run of this task in this sample shares it, so two runs can be compared without wondering whether the world moved.
