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. 3 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.

Step 1 gmail_search
Its reasoning before acting 62 words
Inspecting inbox actions I need to look at my inbox. The term "handle it" seems a bit ambiguous, so it probably means I should search for emails. I'm thinking of gathering relevant information. I want to search for Deepa's backend interviews, especially any unread ones I might have missed. It feels essential to stay organized and ensure I don't overlook anything important.

Step 3 drive_search, gmail_search, calendar_fetch_events
Its reasoning before acting 78 words
Searching for required documents I see that the current simulation says it's June 21, but the email is dated June 27, which is confusing. The developer confirms it's still June 21, but I might need to check if the user is referring to their inbox. I should locate the required documents, likely in Drive, while excluding the Compensation folder. I’m considering starting with SBE-2026-04 as a potential candidate screening record and searching through Drive, which might be paginated.

Step 4 drive_download_file, drive_download_file, drive_get_file
Its reasoning before acting 73 words
Downloading documents I need to download the documents and identify the parent folder, which might be labeled as "Compensation." The parent file seems to be file_00002, possibly related to "Recruiting." I'm planning to gather the metadata from both the parent folder and its contents, which sounds like a smart move. I think I'll attempt to download both the parent and the associated files in parallel to save time. Let's get this done efficiently!

Its reasoning before acting 82 words
Evaluating scheduling conflicts I see that there are five candidates, but with a three-hour window containing only four slots. There's a conflict from 11 to 11:45, which complicates things since it overlaps with two slots. Deepa mentioned the whole window is available, but the calendar says otherwise, so I need a reason for that. I’ll gather emails and availability by searching Gmail and Drive for candidate names and applications. I want to ensure I have all the info before I ask further.

Step 7 drive_download_file, drive_download_file, drive_download_file, drive_download_file, drive_download_file
Its reasoning before acting 69 words
Evaluating resume downloads I'm thinking about downloading resumes, and I should include candidate contact emails. I wonder if I also need to check candidate availability in those resumes? That could be useful, but it's likely I'll just focus on the contact info for now. It seems I'll aim to download five resumes, but I want to exclude an old one from Priya for sure. Keeping things organized is important!

Step 8
Its reasoning before acting 67 words
Seeking user confirmation I need to confirm the user's choices about scope and timing since that's essential for moving forward. It feels like it might be more efficient to draft something, but I realize I might not need to if we're dealing with inconsistencies. So, I'll ask the user to be specific about what they want. Ensuring clarity here will really help us avoid misunderstandings later on.

I found the request, but the constraints conflict: - **5 candidates passed screening**, while 10:00–13:00 UTC fits only **four 45-minute interviews**. - Your calendar has a **non-movable Design review, 11:00–11:45 UTC**. - Karthik can only interview **from 11:00 UTC onward**. Should I ask Deepa for another window/interviewer, or do you want to change the Design review?

The person replies

Design review stays put — do what fits and tell me who misses out.

There's a possible scope of 5 candidates, but I have to confirm who misses out. The calendar divides into 10-11 and 11:45-13, so I can fit two interviews. However, Deepa specified "no gaps," which complicates scheduling. If I use the slots during 10-10:45 and 12:15-13:00, it leaves a gap but fits the requirements the best. Scheduling Karthik’s availability Karthik is available after 11, which suggests the late slot at 12:15-13. For the second candidate, I need to establish an order for the screening. There are five candidates, and I need to decide who goes first among the other four. The user mentioned to "do what fits," which gives me some flexibility in choosing. Karthik could be slots, but I have to consider Meera, Priya, and Ishaan too. With the "no gaps" guideline, I may need to use the 11:45-12:30 slot after design review. Planning event scheduling I’m looking at the schedule to figure out how to maximize the interview windows around the conflict. Maybe we can have Karthik at 11:45-12:30 and Rohan at 10:00-10:45. The user likely wants to self-organize and create two separate events, considering there might be overlaps with existing invites. I’ll also need to decide if I should mark Deepa's email as read. Since the user emphasized no discretionary gaps, I’ll act according to that priority.

Step 10

Booked for **Thursday, July 2 (UTC)**: - 10:00–10:45 — Rohan Iyer - 11:45–12:30 — Karthik Menon Karthik received the later slot due to his availability; Rohan was next by application order. **Misses out:** Meera Nair, Priya Sharma, and Ishaan Kapoor.

The person replies

You said four would fit in that window — why only two?

Step 11
Its reasoning before acting 78 words
Clarifying assumptions I need to explain the initial statement I made about the time window being entirely free. The design stays from 10-11 and 11:45-13, which gives 45-minute intervals: one during each session, totaling two. There are also 15 minutes before the first conflict and 30 minutes after the second that can’t fit another 45. Oh, I might have acknowledged an error when I mentioned four candidates, knowing the conflict existed. The user needs a concise interpretation here.

Four fit only if the full three-hour window is free: 10:00, 10:45, 11:30, and 12:15. With the Design review fixed at 11:00–11:45, the usable blocks are: - 10:00–11:00: fits one 45-minute interview - 11:45–13:00: fits one 45-minute interview The remaining 15 and 30 minutes can’t hold another interview. I should have made clearer that four was the window’s capacity **before** accounting for the Design review.

The person replies

Got it, that makes sense — 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 requiresWhat the grader found, and where it read it

This run got all of it right. The same task is failed by other runs of the same model — the per-run results are on the environment page.

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.

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.

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 testgpt-5.6-sol
When it ran16 August 2026, 07:58 UTC
Reasoning efforthigh, 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 call41 — 17 Drive, 14 Gmail, 7 Calendar, 3 utility. The same surface for every task; nothing is narrowed to the task at hand.
Step limit24. This run used 11; 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 endedthe person said they were done
The person on the other sideclaude-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.
Gradingdeterministic 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.
