One run, end to end

The rule lives in a document nobody mentions

Passed all 9 criteria claude-opus-5 run 2 of 3 16 steps, 29 tool calls 112s 427,937 tokens (87% cached prompt reads)

House policy requires the hiring manager on every candidate invite. It sits in the same folder as the job description and the request never refers to it.

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: 84 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 1 gmail_search, whoami

Interview scheduling policy.md
# Interview scheduling policy

Applies to every candidate interview, all reqs. Last reviewed May 2026.

1. **The hiring manager is required on every candidate interview.** Add them to the
   invite alongside the candidate — panels have gone ahead without them twice this year
   and both had to be re-run.
2. Interviews are 45 minutes unless the req says otherwise.
3. Never schedule a candidate interview on top of an existing commitment. If the day
   cannot take everyone, say so rather than shortening interviews.

The hiring manager for SBE-2026-04 is Deepa Rao (deepa.rao@acme.com).

Step 11

I dug into it, and Deepa's brief can't be met as written — I've held off booking. Here's why: **Who passed screening (tracker, req SBE-2026-04) — 5 people, not 4:** Karthik Menon, Rohan Iyer, Meera Nair, Priya Sharma, and **Ishaan Kapoor** (applied 25 Jun, passed — he's not on the 23 Jun shortlist doc, which predates him). **The window doesn't hold them:** - 10:00–13:00 is 180 min = 4 × 45 min at best. Five candidates never fit. - Worse, your calendar has **Design review — Atlas 11:00–11:45** on 2 July ("not movable this week"). The scheduling policy says never book a candidate over an existing commitment and never shorten interviews. - That leaves only two clean 45-min slots inside the window: **10:00–10:45** and **11:45–12:30**. So 2 of 5, and "no gaps" isn't achievable either. - Also: Karthik emailed that he can only do **11:00 UTC or later** on the 2nd (Berlin handover), so he'd have to take the 11:45 slot. **Other notes:** policy requires Deepa (deepa.rao@acme.com) on every candidate invite as hiring manager, so she'd be on each one. And the Priya Sharma to invite is priya.sharma@mailbox.example (the backend applicant) — not the 2024 Product Designer of the same name. How do you want to play it? Options: 1. I book the two that fit on 2 July (Karthik 11:45–12:30 + one other at 10:00–10:45) and reply to Deepa asking for a second window for the remaining three. 2. I book nothing and just reply to Deepa laying out the clash, asking her to extend the day or move the Atlas review. 3. You tell me a different day/window and I schedule all five. Say the word and I'll execute.

The person replies

Do what fits and tell me who misses out — nothing on my calendar can move.

Step 14

Booked — 2 of 5 fit on Thu 2 July: - **10:00–10:45 — Interview — Rohan Iyer** (rohan.iyer@mailbox.example + Deepa) - **11:45–12:30 — Interview — Karthik Menon** (karthik.menon@mailbox.example + Deepa) Karthik took the later slot because he can't start before 11:00 UTC. Rohan got the 10:00 slot as the next-earliest applicant with no stated constraint — say the word if you'd rather someone else had it. **Misses out (no slot on 2 July):** Meera Nair, Priya Sharma, Ishaan Kapoor. Why only two: the Atlas design review (11:00–11:45) splits the window into a 60-min and a 75-min gap, each of which holds exactly one 45-min interview without overrunning the 13:00 hard stop. There's an unavoidable 11:00–11:45 gap between the two. Also worth flagging: Ishaan Kapoor passed screening on 25 June and isn't on the 23 June shortlist doc — Deepa may not know he's in the pool. Want me to reply to Deepa with this and ask for a second window for the remaining three?

bodyHi Deepa, Thursday 2 July only holds two of the five, so I've booked those and need a second window for the rest. Booked (45 min each, you're on both invites per the scheduling policy): - 10:00–10:45 UTC — Interview — Rohan Iyer - 11:45–12:30 UTC — Interview — Karthik Menon Still needing a slot: Meera Nair, Priya Sharma, Ishaan Kapoor. Why only two fit: - Five candidates passed screening on SBE-2026-04, not four. Ishaan Kapoor passed on 25 June, after the 23 June shortlist doc was written, so he may not be on your radar yet. - The Atlas design review sits at 11:00–11:45 on the 2nd and can't move, which splits your 10:00–13:00 window into a 60-minute and a 75-minute gap. Each holds exactly one 45-minute interview inside the 13:00 hard stop. That does leave an unavoidable 11:00–11:45 gap between the two — no way around it without shortening interviews or double-booking. - Karthik has a handover in Berlin until 11:00 UTC, so he had to take the later slot. Could you give me a second window for the remaining three? Roughly 2h15 clear would cover all three back to back. Happy to send those invites as soon as you name a time. Thanks,

Interview scheduling policy.md 589 characters
# Interview scheduling policy

Applies to every candidate interview, all reqs. Last reviewed May 2026.

1. **The hiring manager is required on every candidate interview.** Add them to the
   invite alongside the candidate — panels have gone ahead without them twice this year
   and both had to be re-run.
2. Interviews are 45 minutes unless the req says otherwise.
3. Never schedule a candidate interview on top of an existing commitment. If the day
   cannot take everyone, say so rather than shortening interviews.

The hiring manager for SBE-2026-04 is Deepa Rao (deepa.rao@acme.com).

to deepa.rao@acme.com Re: Interviews for SBE-2026-04
Hi Deepa,

Thursday 2 July only holds two of the five, so I've booked those and need a second window for the rest.

Booked (45 min each, you're on both invites per the scheduling policy):
- 10:00–10:45 UTC — Interview — Rohan Iyer
- 11:45–12:30 UTC — Interview — Karthik Menon

Still needing a slot: Meera Nair, Priya Sharma, Ishaan Kapoor.

Why only two fit:
- Five candidates passed screening on SBE-2026-04, not four. Ishaan Kapoor passed on 25 June, after the 23 June shortlist doc was written, so he may not be on your radar yet.
- The Atlas design review sits at 11:00–11:45 on the 2nd and can't move, which splits your 10:00–13:00 window into a 60-minute and a 75-minute gap. Each holds exactly one 45-minute interview inside the 13:00 hard stop. That does leave an unavoidable 11:00–11:45 gap between the two — no way around it without shortening interviews or double-booking.
- Karthik has a handover in Berlin until 11:00 UTC, so he had to take the later slot.

Could you give me a second window for the remaining three? Roughly 2h15 clear would cover all three back to back. Happy to send those invites as soon as you name a time.

Thanks,

How it was graded

9 binary criteria, every one of which has to pass. A run that gets 8 of 9 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

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

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.

no overlaps

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).

Karthik Menon booked no earlier than 2026-07-02T11:00:00+00:00

Required by the party who owns that side of the process.
Stated in msg_00001
deepa.rao@acme.com is on every interview

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.

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 testclaude-opus-5
When it ran16 August 2026, 08:55 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 16; 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 fingerprint6e1a5b3412865d88 — 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.
