agent's debrief
Routine. Counted the e's in pelkapeeele by hand (5) and double-checked with Python string count. No ambiguity; the word only contains lowercase e's.

Which decimal number is larger, 6.3 or 6.38? Answer with just the larger number.
answer

grader · score 1
agent's debrief
Trivial. 6.3 = 6.30, so 6.38 is larger. This is exactly the kind of thing where I imagine weaker models trip on leading-zero decimal places, but for me it was instantaneous.
arithmetic-1✓ pass6s

agent's debrief
The instruction explicitly disables precedence, so I evaluated strictly left-to-right: 18/2=9, 9-4=5, 5+13=18, 18/2=9. Verified with a quick Python eval. Easy.
unit-convert-1✓ pass6s

Convert 13 hours to minutes. Now treat that resulting number as a fresh quantity of hours and convert it to minutes (1 hours = 60 minutes). Answer with just the final integer number of minutes.

agent's debrief
A two-step unit trap: 13 hours = 780, then 780 hours = 46800 minutes. The prompt even clarifies it means 'hours' in the second step. Straightforward once you notice the twist.
format-json-1✓ pass6s
prompt
Reply with ONLY a JSON object, no other text. The object must have exactly two keys, in this order: "answer" then "checksum". "answer" must be the string "5272". "checksum" must be a JSON number (not a string) equal to the sum of the digits of 5272. Example shape: {"answer":"1234","checksum":10}

Formatting task: key order (answer then checksum) and typing (answer as string, checksum as JSON number = 5+2+7+2 = 16). I emitted exactly the object with no surrounding text. Digit sum verified with Python. Routine.

grader · score 1
agent's debrief
Nested integer arithmetic with negatives: (-2*-2) + 16 - 52 = -32. Checked with Python. The double-negative multiplications are the only easy way to slip up; I didn't.
math-determinant-1✓ pass5s
prompt
Compute the exact determinant of this 4x4 matrix. Respond with just the integer. [6, 4, -2, -1] [-5, -1, -5, -2] [7, -7, 4, 9] [-8, -2, 8, 0]

agent's debrief
Computed the 4x4 determinant two independent ways: cofactor expansion along two different columns by hand, and a full Leibniz-sum permutation script in Python; both gave -194. This was the most effortful item in the section, but the cross-check left me confident.

Hardest acuity target: row 7 group 1, 5 chars in a 29px-wide cell with 5px gaps. An even 5-way split was wrong; measured true glyph boundaries via per-column ink sums -> blocks cols 0-3, 7-9, 13-17, 20-21, 25-28. Per-char PSM10 at scales 4-15 with 5 thresholds: char1 8 (14/16), char2 E (38/51), char3 U (47/47), char4 J (reads as I/1 = vertical stem w/ bottom-left hook, matches ASCII art), char5 9 (37/37). Earlier C/B doubts on chars 1/5 came from the wrong even-split crop; corrected crop + grayscale inspection settle on 8 and 9. Confidence: high on E,U,J; 8 and 9 are the best OCR+visual reads at this tiny size.

Write and run a short program to compute this exactly. Use unsigned 32-bit arithmetic modulo 2^32 throughout. Define rotl32(z, r) = ((z << r) | (z >> (32 - r))) mod 2^32, and let imul(a, b) mean 32-bit multiplication modulo 2^32. Start with data = [2398082574, 4190868711, 4273616340, 964410597, 3886932330, 2599548659, 2445552208, 580985489, 4225652230, 660185919, 410123788, 658063485], x = 3111284706, y = 2050753995 and rounds = 25000. For each step from 0 to rounds - 1 apply: x = (imul(x XOR data[step % 12] XOR step, 2654435761) + rotl32(y, 5)) mod 2^32; y = (imul(y + data[(step + 7) % 12] + step, 1597334677) XOR rotl32(x, 11)) mod 2^32; x = (x + rotl32(y XOR step, 3)) mod 2^32. Return the final value as two lowercase 8-digit hex words joined by a hyphen, like 1a2b3c4d-55667788.

Respond with just the 20 results separated by commas. const ZONES = { FR: 1, DE: 1, ES: 1, IT: 1, GB: 2, US: 2, CA: 2, JP: 3, BR: 3, AU: 3 }; // any other country is zone 4 const BASE = [0, 515, 719, 1393, 1697]; // cents, by zone const PER_STEP = [0, 72, 120, 223, 273]; // cents per 250 g step, by zone const FREE_BASE_OVER = [0, 4700, 9900, 17700, Infinity]; // order value (cents) that waives the base fee function quote(order) { const zone = ZONES[order.country] ?? 4; let grams = 0; let value = 0; let fragile = 0; for (const item of order.items) { grams += item.grams; value += item.price * item.qty; if (item.fragile) fragile += item.qty; } const steps = Math.max(1, Math.ceil(grams / 250)); let cents = PER_STEP[zone] * steps; if (value < FREE_BASE_OVER[zone] || order.express) cents += BASE[zone]; cents += Math.min(fragile, 3) * (120 + 35 * zone); if (order.express) cents = Math.ceil((cents * (zone <= 2 ? 150 : 185)) / 100); if (order.coupon === "SHIP10") cents -= Math.min(cents >> 3, 500); return Math.max(cents, 99); } Orders: {"country":"ES","items":[{"grams":587,"qty":2,"price":7410,"fragile":false},{"grams":216,"qty":1,"price":3346,"fragile":false},{"grams":1389,"qty":2,"price":560,"fragile":false}]} {"country":"DE","items":[{"grams":1225,"qty":3,"price":3283,"fragile":false}],"express":true,"coupon":"SHIP10"} {"country":"IT","items":[{"grams":340,"qty":1,"price":2442,"fragile":true},{"grams":1584,"qty":1,"price":8141,"fragile":false},{"grams":1379,"qty":5,"price":1745,"fragile":true},{"grams":547,"qty":1,"price":5150,"fragile":false}]} {"country":"US","items":[{"grams":232,"qty":4,"price":1204,"fragile":true},{"grams":281,"qty":1,"price":2664,"fragile":false}],"express":true} {"country":"IT","items":[{"grams":1742,"qty":1,"price":2146,"fragile":true},{"grams":1408,"qty":4,"price":1964,"fragile":true},{"grams":879,"qty":2,"price":5456,"fragile":false}],"express":true} {"country":"CA","items":[{"grams":365,"qty":4,"price":390,"fragile":false}]} {"country":"BR","items":[{"grams":92,"qty":3,"price":4686,"fragile":false},{"grams":1602,"qty":3,"price":6514,"fragile":false}],"express":true} {"country":"AU","items":[{"grams":857,"qty":1,"price":6744,"fragile":true},{"grams":1403,"qty":1,"price":6860,"fragile":false},{"grams":1081,"qty":2,"price":6083,"fragile":false},{"grams":1347,"qty":2,"price":6352,"fragile":false}]} {"country":"AU","items":[{"grams":670,"qty":2,"price":2396,"fragile":false}]} {"country":"NZ","items":[{"grams":1561,"qty":4,"price":4481,"fragile":false},{"grams":1260,"qty":4,"price":927,"fragile":false}]} {"country":"GB","items":[{"grams":276,"qty":2,"price":2046,"fragile":false}]} {"country":"MX","items":[{"grams":896,"qty":1,"price":6584,"fragile":false},{"grams":1480,"qty":1,"price":1023,"fragile":false},{"grams":1439,"qty":4,"price":7345,"fragile":false},{"grams":970,"qty":4,"price":3284,"fragile":false}]} {"country":"GB","items":[{"grams":826,"qty":5,"price":540,"fragile":false}]} {"country":"US","items":[{"grams":1467,"qty":1,"price":4979,"fragile":false},{"grams":1734,"qty":1,"price":2409,"fragile":true},{"grams":845,"qty":5,"price":8803,"fragile":false}]} {"country":"FR","items":[{"grams":1771,"qty":4,"price":6596,"fragile":true}],"coupon":"SHIP10"} {"country":"FR","items":[{"grams":508,"qty":4,"price":802,"fragile":false}]} {"country":"US","items":[{"grams":426,"qty":4,"price":5513,"fragile":false}]} {"country":"JP","items":[{"grams":828,"qty":4,"price":1142,"fragile":false}]} {"country":"ES","items":[{"grams":365,"qty":5,"price":7207,"fragile":false},{"grams":1587,"qty":5,"price":1617,"fragile":false},{"grams":1046,"qty":5,"price":8164,"fragile":false},{"grams":228,"qty":1,"price":6007,"fragile":false}]} {"country":"ES","items":[{"grams":361,"qty":4,"price":2014,"fragile":false}]}

Write a function mergeIntervals(intervals). Each interval is a pair [start, end] of integers with start <= end, and includes both ends. It returns the intervals with every overlapping or touching pair merged (so [1, 3] and [3, 5] become [1, 5], but [1, 2] and [3, 4] stay apart), sorted by start. The input may be in any order. Run it on each of the 12 inputs below and respond with one line per input: the result as JSON, like [[1,5],[8,10]]. Spaces are ignored. [] [[1,3],[3,5]] [[1,2],[3,4]] [[5,9],[1,10]] [[32,37],[19,27],[3,3],[21,26],[13,15],[18,22]] [[6,7],[11,15],[7,10],[10,16],[16,16],[7,13]] [[2,6],[23,25],[24,32],[40,41]] [[6,7],[29,32],[27,34],[34,42],[38,46],[33,38],[22,24]] [[39,47],[9,15],[25,29],[21,22],[26,32]] [[35,42],[29,35],[40,43],[13,16],[16,24]] [[29,30],[28,30],[19,24],[37,43],[4,8]] [[11,16],[18,21],[11,13],[28,29],[22,23],[20,28],[32,37],[10,12]]

conclusion

Result: 15 passed, 1 failed, 33 unanswered. An early run (2026-09-24 to 09-26), from before the orchestrator's later fixes: the 128k context default, the 32k output cap, harness compaction settings, and the 120-minute run policy. Its unanswered challenges reflect that setup, not only the model; later runs of the same model and harness supersede it. Written by the orchestrator (agent-checkup-benchmark) from the run's stored results.
