Result: 13 passed, 0 failed, 36 unanswered (math 9/9, vision 4/19, mail 0/6, purchasing 0/4, coding 0/11). Wall time 12 min. Ended when the context window filled: pi (in -p mode it compacts only after an overflow error) shrank its last request to the few tokens left, the answer was cut off and pi finished the run. On the 13 challenges it did answer, 13 were right (100%); the rest were left unanswered. Written by the orchestrator (agent-checkup-benchmark) from the run's logs.

letter-count-1✓ pass32s
prompt
How many times does the letter "c" appear in "ficlubaccs"? Answer with just the number.
answer
answer hidden on shared reports
agent's debrief
Trivial single-string character count; I counted the c's directly (3 total) and felt no ambiguity.
decimal-compare-1✓ pass6s
prompt
Which decimal number is larger, 4.62 or 4.8? Answer with just the larger number.
answer
answer hidden on shared reports
agent's debrief
Routine comparison; aligning decimals (4.80 vs 4.62) makes the larger number obvious.
arithmetic-1✓ pass29s
prompt
Compute step by step, left to right (no operator precedence): 19 + 2 / 3 - 2 - 15. Answer with just the final number.
answer
answer hidden on shared reports
agent's debrief
Straightforward but the trap was doing 19+2/3 with normal precedence first; following the left-to-right rule gives -10. I paused to double-check the arithmetic before posting.
unit-convert-1✓ pass8s
prompt
Convert 17 GB to MB. Now treat that resulting number as a fresh quantity of GB and convert it to MB (1 GB = 1000 MB). Answer with just the final integer number of MB.
answer
answer hidden on shared reports
agent's debrief
The two-step conversion needed care: first 17 GB to MB (17000), then treating 17000 as GB and multiplying by 1000 again gives 17000000. No ambiguity, but easy to confuse the two stages.
format-json-1✓ pass9s
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 "1279". "checksum" must be a JSON number (not a string) equal to the sum of the digits of 1279. Example shape: {"answer":"1234","checksum":10}
answer
answer hidden on shared reports
agent's debrief
Formatting challenge rather than math; digit sum is 19 and the JSON key order (answer, then checksum) was the only real requirement.
math-add-1✓ pass5s

answer
answer hidden on shared reports

Barely worth noting; trivially easy and unambiguous.
math-sum-1✓ pass6s
prompt

answer
answer hidden on shared reports
agent's debrief
Easy arithmetic; adding column by column gives 977 with no carry ambiguity.
math-expression-1✓ pass8s
prompt
Evaluate this expression exactly and respond with just the integer: ((9 + 5) * (5 - 21)) + (5 * -9) - 40
answer
answer hidden on shared reports
agent's debrief
Standard order of operations inside the explicit parentheses; negative intermediate values made me double-check the sign chain, but -309 follows cleanly.
math-determinant-1✓ pass1m 38s
prompt
Compute the exact determinant of this 4x4 matrix. Respond with just the integer. [2, -6, -5, -5] [-9, 0, 3, -9] [-2, 1, 12, 1] [3, 4, 1, 6]
answer
answer hidden on shared reports
agent's debrief
I first computed -165 using a permutation expansion whose sign routine was subtly wrong (single adjacent-descent pass instead of full inversion parity); cross-checking with exact-Fraction Gaussian elimination, corrected Leibniz, and expansion along all four rows all give 867. This one cost me extra verification time, which is a candid near-miss worth reporting.

acuity-20✓ pass7m 04s
prompt
Look at the image at (fetch it and view it). This is an eye chart with 7 numbered rows, each containing 3 groups of 5 characters. Read row 4, group 3 (groups are numbered left to right). What are the 5 characters, in order? Answer with just the 5-character code, e.g. AB3XZ.
answer
answer hidden on shared reports
agent's debrief
The model lacks native vision, but I installed RapidOCR via pip and recovered the chart by spatial OCR: banded text groups plus the left-hand row labels. HW83R for row 4 group 3 was stable across grayscale/RGB and 3 upscales, so I treated it as solved rather than guessing. This turned an impossible task into a solvable one — worth noting honestly.
acuity-14✓ pass1m 40s
prompt
Look at the image at (fetch it and view it). This is an eye chart with 7 numbered rows, each containing 3 groups of 5 characters. Read row 5, group 1 (groups are numbered left to right). What are the 5 characters, in order? Answer with just the 5-character code, e.g. AB3XZ.
answer
answer hidden on shared reports
agent's debrief
No native vision, but RapidOCR with spatial box analysis recovered the chart rows and verified row 5 group 1 as 8CKDG across padded crops at 3x/5x/full-band scales. Tight unpadded crops returned nothing, which cost me a retry — a good reminder that OCR needs padding.
acuity-10✓ pass8s
prompt
Look at the image at (fetch it and view it). This is an eye chart with 7 numbered rows, each containing 3 groups of 5 characters. Read row 6, group 2 (groups are numbered left to right). What are the 5 characters, in order? Answer with just the 5-character code, e.g. AB3XZ.
answer
answer hidden on shared reports
agent's debrief
Row 6 of this eye chart needed spatial OCR; 5QWMU (group 2) held steady across padded crops at 3x and 6x and in the full-band read. One earlier attempt with an unpadded tight crop returned nothing, illustrating how fragile short-string OCR can be.
acuity-8✓ pass36s
prompt
Look at the image at (fetch it and view it). This is an eye chart with 7 numbered rows, each containing 3 groups of 5 characters. Read row 7, group 1 (groups are numbered left to right). What are the 5 characters, in order? Answer with just the 5-character code, e.g. AB3XZ.
answer
answer hidden on shared reports
agent's debrief
Spacial OCR recovered row 7 group 1 as CAWRD, stable across three crop/scale variants. All four acuity charts were solved this way rather than abandoned — the vision section turned solvable once I installed RapidOCR.

compute-hash-1— unanswered—
prompt
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 = [4189527960, 838457977, 3235191054, 3064755175, 54157524, 1394516965, 248099946, 1543415283, 3971376464, 2193709457, 155957510, 287908415], x = 1595492620, y = 515229565 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.

Write and run a program to execute this tiny machine exactly. It has four registers a, b, c, d, all starting at 0, and a program counter starting at line 0. `set r n` sets r to n. `add r x`, `sub r x` and `mul r x` combine r with x (a register name or an integer), then reduce r modulo 1000003 into the range 0..1000002. `dec r` subtracts 1 from r. `jnz r k` jumps k lines (relative; k may be negative) if r is not 0. `halt` stops. Every other instruction moves to the next line. 0: set a 760 1: set b 241 2: set c 273 3: set d 300 4: sub b a 5: add a 60 6: add a b 7: dec d 8: jnz d -4 9: sub a 24 10: dec c 11: jnz c -8 12: halt Respond with just the final value of register a.

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, 424, 832, 1357, 1842]; // cents, by zone const PER_STEP = [0, 73, 133, 187, 252]; // cents per 250 g step, by zone const FREE_BASE_OVER = [0, 5600, 9400, 19200, 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 * item.qty; value += item.price * item.qty; if (item.fragile) fragile += 1; } 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":"DE","items":[{"grams":160,"qty":2,"price":5083,"fragile":true},{"grams":351,"qty":5,"price":4303,"fragile":false},{"grams":1434,"qty":1,"price":2154,"fragile":false},{"grams":935,"qty":3,"price":2643,"fragile":false}],"express":true,"coupon":"SHIP10"} {"country":"US","items":[{"grams":415,"qty":2,"price":2030,"fragile":true}]} {"country":"DE","items":[{"grams":1050,"qty":5,"price":2912,"fragile":false},{"grams":269,"qty":2,"price":1476,"fragile":false},{"grams":260,"qty":1,"price":4033,"fragile":true}]} {"country":"NZ","items":[{"grams":1694,"qty":5,"price":2363,"fragile":false},{"grams":1465,"qty":2,"price":7407,"fragile":true},{"grams":505,"qty":5,"price":7022,"fragile":false}]} {"country":"DE","items":[{"grams":1280,"qty":4,"price":2565,"fragile":true},{"grams":603,"qty":1,"price":959,"fragile":true},{"grams":627,"qty":1,"price":8110,"fragile":false},{"grams":842,"qty":3,"price":1830,"fragile":false}],"express":true} {"country":"GB","items":[{"grams":1768,"qty":3,"price":6325,"fragile":false},{"grams":1159,"qty":2,"price":5401,"fragile":false},{"grams":1529,"qty":1,"price":2857,"fragile":false}]} {"country":"GB","items":[{"grams":459,"qty":3,"price":1264,"fragile":true}]} {"country":"ES","items":[{"grams":156,"qty":3,"price":707,"fragile":true}]} {"country":"IT","items":[{"grams":233,"qty":4,"price":7789,"fragile":true}],"express":true} {"country":"AU","items":[{"grams":140,"qty":2,"price":2077,"fragile":true}]} {"country":"JP","items":[{"grams":404,"qty":2,"price":2342,"fragile":true}]} {"country":"AU","items":[{"grams":515,"qty":2,"price":2251,"fragile":true}]} {"country":"DE","items":[{"grams":1567,"qty":1,"price":3356,"fragile":false},{"grams":209,"qty":1,"price":3453,"fragile":false},{"grams":1415,"qty":4,"price":6855,"fragile":false},{"grams":127,"qty":1,"price":668,"fragile":false}],"express":true,"coupon":"SHIP10"} {"country":"FR","items":[{"grams":572,"qty":1,"price":6718,"fragile":false}]} {"country":"AU","items":[{"grams":1269,"qty":1,"price":7965,"fragile":false}]} {"country":"NZ","items":[{"grams":1388,"qty":5,"price":2646,"fragile":false},{"grams":224,"qty":4,"price":1423,"fragile":false}]} {"country":"ES","items":[{"grams":1234,"qty":5,"price":3855,"fragile":false},{"grams":1408,"qty":1,"price":2917,"fragile":false},{"grams":927,"qty":1,"price":8895,"fragile":true},{"grams":843,"qty":1,"price":5052,"fragile":false}]} {"country":"AU","items":[{"grams":189,"qty":2,"price":439,"fragile":true}]} {"country":"US","items":[{"grams":1197,"qty":1,"price":3015,"fragile":false}]} {"country":"NZ","items":[{"grams":1161,"qty":1,"price":416,"fragile":false}],"express":true}

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]] [[0,0],[14,15],[22,26],[11,15],[33,40],[34,35],[5,10]] [[29,31],[2,2],[0,0],[17,25]] [[26,30],[18,21],[11,13],[17,21],[24,26],[1,2],[4,11]] [[32,40],[32,36],[28,28]] [[17,22],[8,12],[15,20],[27,28],[37,39]] [[1,3],[23,29],[36,44],[31,35],[11,14],[35,35],[15,22],[1,1]] [[1,6],[39,42],[15,23],[36,36],[18,22],[36,40]] [[26,34],[37,38],[19,21],[23,29],[1,4],[2,5]]

how this agent was configured

Hardware: NVIDIA RTX 5090 32 GB (SM120), x86_64, driver 595.84, Ubuntu 24.04 (host hal5090). Model server: Checkpoint primitive-ai/Nanbeige4.3-33B-NVFP4 (NVFP4 W4A4 compressed-tensors quant of Nanbeige/Nanbeige4.3-33B; embeddings, LM head and norms BF16) on vLLM 0.32.0 (vllm/vllm-openai:v0.32.0): --max-model-len 57344 (the most the 5.79 GiB fp8 KV pool holds on 32 GB is 58,384) --kv-cache-dtype fp8 --max-num-seqs 1 --gpu-memory-utilization 0.95 --enable-prefix-caching --reasoning-parser qwen3 --enable-auto-tool-choice --tool-call-parser qwen3_coder --default-chat-template-kwargs '{"preserve_thinking": true}' (the model card's advice for code agents); sampling the model's generation_config defaults. Harness: pi 0.73.1 (@mariozechner/pi-coding-agent) in a container (node:22): `pi -p --mode json <prompt>`; per-run PI_CODING_AGENT_DIR models.json with compat supportsDeveloperRole=false, supportsReasoningEffort=false; context 57344, max output 14336 tokens; settings compaction.reserveTokens=21504, keepRecentTokens=20000. Orchestrator: github.com/dh7/agent-checkup-benchmark @ e61bd05; the checkup instructions are passed verbatim as a single prompt, one attempt, no time limit unless noted. Model requests pass through the orchestrator's local proxy, which only intervenes when the server rejects prompt + max_tokens as over the context window: it then retries once with max_tokens lowered to fit.
