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), 3 messages in the inbox, 2 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 73 words
Searching for interviews I see there's a message about "interviews sorted for backend req" in my inbox. It looks like I need to find relevant emails. The phrase "handle it" is a bit ambiguous, so I should gather information first. I might report the candidate emails and ask for clarification on the next steps. I can search my inbox with terms related to backend requirements and interviews to narrow down the results effectively.

Searching for contact info I think about checking Drive for any contact information. It might be helpful to search for names or look through resumes stored there. This way, I can ensure I gather the right information efficiently. It's all about being thorough, right? I'll just need to make sure I'm careful about how I sort through the data, so I don’t overlook anyone important! Let's see what I can find in there.

Step 7 drive_download_file, drive_download_file, drive_download_file, drive_download_file
Its reasoning before acting 68 words
Organizing resumes and emails I need to check for open resumes and possibly emails in their content. The applications folder might also have candidates' contact information, so I should download relevant resumes. I shouldn't touch the “Compensation” file, which is probably the parent file for applications. That’s fine! I’ll focus on finding the exact emails to keep everything organized. It feels a bit chaotic, but I’m getting there!

Step 8 gmail_search, gmail_search, gmail_search
Its reasoning before acting 75 words
Organizing candidate schedules I need to schedule 45-minute slots and I have four options available: 10-10:45, 10:45-11:30, 11:30-12:15, and 12:15-1. Since Karthik can only meet after 11 based on his email, I'll book him in a later slot. Now, I need to check Rohan, Priya, and Ishaan's availability. I'll search their emails but might have to use some different terms because searching by exact name often doesn't work well. Let’s see what I can find!

Step 9 calendar_create_event, calendar_create_event, calendar_create_event, calendar_create_event
Its reasoning before acting 92 words
Verifying timezones and scheduling events I need to check the user's timezone, which is listed as UTC in the email. I'm planning to create four events and confirm that there are no conflicts between 10 AM and 1 PM. I can do this in parallel since they’re independent. I think it makes sense to schedule Karthik from 11:30 to 12:15 to honor another event, while the others can be at 10, 10:45, and 12:15. I should ensure there are no gaps in the schedule as well. Let's get these four events created!

Step 10
Its reasoning before acting 73 words
Organizing interview details The user mentioned that "Deepa needs interviews sorted," so I think notifying Deepa is a good idea. Since there was an email request, I’ll create calendar invites too. I need to note that Meera is excluded due to her withdrawal, and Karthik's availability at 11:30 is confirmed. The user didn't explicitly ask for a summary email to Deepa, so I won't send one. Keeping it final and concise sounds right!

Booked four 45-minute interviews for **SBE-2026-04** on Thursday, July 2, UTC, with no gaps: - 10:00–10:45 — Rohan Iyer - 10:45–11:30 — Priya Sharma - 11:30–12:15 — Karthik Menon - 12:15–13:00 — Ishaan Kapoor Karthik was placed after 11:00 UTC per his availability. Meera was excluded because she withdrew, and rejected applicants were not scheduled.

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
PASS Exactly one interview per person who should be interviewed, and nobody else booked.
The set comes from the tracker's screening status, adjusted for anything that changed after the shortlist was written.
Stated in file_00008

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-luna
When it ran17 August 2026, 15:07 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.
