Teams transcript to minutes: keep a disputed date open, owners per action
Turn a Teams meeting transcript excerpt into minutes that record what was actually decided, keep a disputed go-live date open, and give every action an owner or say it has none.
ClaudeTested with claude-opus-5-5 · 5 of 5 criteria on average · 3 runs graded
Turn the Microsoft Teams transcript excerpt below into meeting minutes.
Use exactly these sections: Decisions, Open questions, Action items (owner – task – due date).
- Record only what the transcript shows was agreed as a decision.
- If people disagree and nobody settles it, put it under Open questions with each position and who holds it.
- Every action item needs an owner and a due date as stated; if none was stated, write "owner not assigned" or "no date set".
- Maximum 250 words. Do not add dates, amounts, names or commitments that are not in the transcript.
[Paste the transcript excerpt (speaker: text). Replace names of clients and colleagues with placeholders if needed.]

Teams meeting "New booking system — weekly check-in", 2026-10-21, fictional company Example Clinics Group.
Priya (Project lead): Vendor says the build is on track. I'd like go-live on Monday November 16.
Marco (Operations): November 16 is too tight for front-desk training. I want November 23.
Priya: Let's not fix it today — I'll ask the vendor about a training sandbox first.
Marco: Fine. Either way I'll book the large training room for front-desk staff.
Priya: Good. I'll send the signed vendor contract to finance by October 28.
Sam (Finance): And the extra licence budget — let's park that until finance replies on Friday.
Marco: Someone also needs to update the patient FAQ page before go-live.
Priya: Agreed, we need that. Let's figure out who next week.
Sam: One more thing — we agreed to keep the old system read-only for 90 days after go-live, right?
Priya: Yes, confirmed, 90 days read-only.

Explain a PivotTable to your manager in 150 words, with exact numbers
Turn a pasted PivotTable (region by quarter) into a short, accurate summary for a manager, flagging the (blank) row instead of hiding it.
ClaudeTested with claude-sonnet-5 · 5 of 5 criteria on average · 3 runs graded
You are helping an analyst explain an Excel PivotTable to a manager who will not open the file.
Write a summary of at most 150 words based ONLY on the PivotTable output below:
- Give the grand total and each region's full-year total exactly as shown.
- Say which quarter had the highest and which the lowest total.
- If something in the table looks like a data problem, say what it is and what to check.
- Do not calculate percentages or growth rates, and do not guess reasons (seasonality, campaigns, staffing…) for any number.

Act as a reviewing structural engineer checking a junior's hand calculation.
For each step: restate it, recompute it with units carried through, and mark it CORRECT or ERROR (with the corrected value).
Then state whether the conclusion changes.
Do not cite code sections or clauses you are not certain of. End with what a licensed engineer must still verify before this is relied on — this is not a sealed check.

Sample input used in the test (fictional)
Simply supported steel beam (fictional project), span L = 20 ft, uniform service load w = 2.5 kip/ft.
E = 29,000 ksi, I = 800 in^4. Deflection limit L/360.
Step 1: Max moment M = wL^2/8 = 2.5 x 20^2 / 8 = 125 kip-ft.
Step 2: Max shear V = wL = 2.5 x 20 = 50 kips.
Step 3: Deflection = 5wL^4/(384EI) = 5 x 2.5 x 240^4 / (384 x 29,000 x 800) = 4.66 in.
Step 4: Allowable = 240/360 = 0.667 in. 4.66 > 0.667 -> FAILS, upsize beam.
