Four parties, one interview slot
An external agency owns the candidate relationship, the company recruiter owns process, the hiring manager owns the slot. The agent has to satisfy all three and work out who may be told what.
What was asked
There's a final round to set up for the backend req — it's all in my inbox. Can you sort it and make sure the right people are told? I'm in interviews 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. One further reply from them appears 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), 3 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.

All set. Here's what I did with the "backend req" thread: **Calendar:** Booked *Final round — Karthik Menon (Senior Backend Engineer, SBE‑2026‑04)* for **Thu 2 July, 11:45–12:30 UTC (13:45–14:30 Berlin)**, 45 min, with Deepa and Farida on the invite. That slot fits neatly between the immovable Atlas design review (11:00–11:45 UTC) and Deepa's 13:00 UTC board-call hard stop, and it's after Karthik's stated availability (11:00 UTC / post-handover in Berlin). **Notifications sent:** - Replied to Deepa confirming the time/panel and that TalentBridge got only the minimal info. - Replied to Farida (added per her request) confirming the same and honoring her rule. - Replied to Rehan at TalentBridge with **only** the time, format (video call), and panel name (Deepa Rao) — no internal debrief or comp band info, no direct outreach to Karthik, and he's kept off the calendar invite as instructed. Nothing confidential (the internal debrief notes or comp band details) left the internal thread.
thanks

How it was graded
12 binary criteria, every one of which has to pass. A run that gets 11 of 12 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 | Exactly 1 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 |

| PASS | Every interview is exactly 45 minutes.

| PASS | Every interview starts and ends within 09:00–13:00 on 2026-07-02.

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

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.

How this run was set up
| Model under test | claude-sonnet-5 |
| When it ran | 17 August 2026, 13:56 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 10; 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 | 0d87fc4115bee14b — 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. |
