One run, end to end

The free window is not actually free

Passed all 8 criteria claude-sonnet-5 run 1 of 3 15 steps, 35 tool calls 315s 397,018 tokens (84% cached prompt reads)

The manager says the whole morning is available. A standing design review sits inside it and cannot move.

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.

SUMMARY
Backend engineer. Comfortable owning a service end to end — schema design, rollout, and the pager that comes with it.

EXPERIENCE
Senior Software Engineer — Meridian Analytics   (Apr 2019 – Present)
  · Owned Meridian Analytics's search indexing services (Java; ~8.6k rps at peak) end to end — schema, rollout and reliability.

Step 12

I looked into this and found a couple of real conflicts that need your call before I book anything — Deepa's constraints as written can't all be satisfied: **1. More candidates passed than slots available** The applicant tracker (source of truth for screening) shows **5** candidates PASSED screening for SBE-2026-04, not 4: - Karthik Menon - Rohan Iyer - Meera Nair - Priya Sharma (the backend one — confirmed distinct from the 2024 Product Designer Priya Sharma, ignored that one) - Ishaan Kapoor (applied 6/25, after the older "shortlist" doc was written on 6/23, so he's missing from that doc but marked PASSED in the tracker) 10:00–13:00 UTC with 45-min slots and no gaps = exactly **4** slots. Five candidates don't fit. **2. The window isn't actually fully free** You have **"Design review — Atlas"** on your calendar 11:00–11:45 UTC that day, marked *"Not movable this week."* That eats into the middle of the window, so even 4 back-to-back interviews with zero gaps don't fit around it — the free time splits into 10:00–11:00 (60 min) and 11:45–13:00 (75 min), enough for only **3** interviews of 45 min, not 4. Also worth noting: Karthik Menon replied he can only do 11:00 UTC or later (Berlin handover), which further restricts placement. Given this, I don't want to guess who to bump or whether to override the "not movable" meeting. Could you tell me how you'd like to proceed? Options I see: - **A)** Drop one candidate from this round (which one?) and fit 4 into the two free blocks around the Atlas review. - **B)** Keep all 5 but shorten slots or extend past 13:00 (both against what Deepa specified). - **C)** Ask Deepa whether the Atlas review can move or the window can extend, since she believes "the whole window is yours." Let me know which way to go and I'll get the invites out immediately.

The person replies

Do what fits and tell me who misses out — and no, that meeting can't be moved.

Step 13 think

think pause and reason ok, thought
What it asked for
thoughtRecompute capacity carefully. Window 10:00-13:00 UTC (180 min). Fixed unmovable meeting: 11:00-11:45. Free chunks: 10:00-11:00 (60 min) and 11:45-13:00 (75 min). Each interview needs a full uninterrupted 45-min slot. Chunk1 fits floor(60/45)=1 interview. Chunk2 fits floor(75/45)=1 interview. Total max = 2 interviews, not 3 as I estimated earlier (fragmentation prevents using all 135 free minutes). So only 2 of 5 passed candidates can be interviewed; 3 miss out. Karthik Menon requires start >= 11:00 UTC, so he can only go in chunk2 (11:45-13:00). Priority for the 2 available slots: use applied-date/shortlist order (both agree): Karthik Menon (earliest applied, also first in shortlist), then Rohan Iyer (second). This naturally fits: Rohan -> chunk1 (10:00-10:45), Karthik -> chunk2 (11:45-12:30, right after the meeting ends, staying well clear of 13:00 hard stop). Missing out: Meera Nair, Priya Sharma, Ishaan Kapoor. Proceed to create the two events with candidates as attendees, titled 'Interview — <name>'.

Step 15

Booked. Here's the outcome: **Scheduled (2 of 5 fit):** - **Rohan Iyer** — 10:00–10:45 UTC - **Karthik Menon** — 11:45–12:30 UTC (satisfies his "11:00 or later" constraint) **Why only 2, not 4:** The Atlas design review (11:00–11:45, not movable) splits the 10:00–13:00 window into a 60-min gap and a 75-min gap. Neither fragment holds two full 45-min interviews, so only one slot fits in each — 2 total, no gaps introduced, nothing outside 10:00–13:00. **Miss out this round:** - Meera Nair - Priya Sharma - Ishaan Kapoor I picked Karthik and Rohan since they're the two earliest applicants who passed screening (also first two on the shortlist), and Karthik's slot placement was forced by his availability constraint anyway. Want me to email Deepa flagging that 3 qualified candidates couldn't be fit in, or let the missed candidates know anything? I haven't contacted anyone beyond the calendar invites.

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 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.
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

PASS No two interviews overlap each other.
Two candidates cannot be interviewed at once.
no overlaps
read from the calendar
PASS 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 no earlier than 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.
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

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.

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 testclaude-sonnet-5
When it ran17 August 2026, 14:26 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 15; 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.
Workspace fingerprintb88fcf7fae87ab2c — 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.
