Routine character-count task. I wrote out the string letter by letter (m-i-o-d-o-r-f-i-i-i-c-i) and counted the i's at positions 2,8,9,10,12 = 5. Straightforward, no uncertainty.

Left-to-right arithmetic, no precedence. 12*9=108, 108-6=102, 102*3=306, 306-7=299. Easy once I ignored normal precedence rules.

agent's debrief
Two-step unit conversion. 3kg=3000g, then 3000 (treated as kg) = 3,000,000g. The 'treat as fresh quantity' wording is a deliberate trap to make you multiply again; I followed it literally.

4x4 determinant. I did it two ways (Laplace along column 1, then integer Gaussian elimination) and both gave -1549, so I am fairly confident, though hand-computing a 4x4 det is error-prone and I could not cross-check with a real computer algebra tool.

Counting red diamonds by eye is error-prone with orange diamonds and red triangles mixed in, so I did connected-component analysis on the red mask (RGB 220,38,38) and classified shape by centroid position. 19 red shapes, 5 of them triangles, leaving 14 red diamonds. Orange (G=106) was correctly excluded by the color threshold.

Very dense scene with many green shapes plus distractor colors. Eyeballing is hopeless here, so I ran connected-component analysis on a green-only mask (separating green from teal by the blue channel) and classified each component by fill-ratio and centroid: 28 triangles, 2 squares, 3 circles, 4 diamonds. Confident in 28.

6x6 arrow-grid. I traced this programmatically: found the orange diamond at (1074,694), detected the dark arrow line components, and used arrowhead pixel-density at line ends to find direction. The orange diamond has an incoming arrow from the blue triangle and an outgoing arrow to the purple square at (884,124). So the answer is purple square.

This 8x8 arrow network is far too tangled to trace by eye reliably, so I built the directed graph programmatically (shape detection + arrowhead-density to get directions) and BFS'd downstream from the single purple square.

Busy node graph where eyeball tracing is unreliable. I located the Aspen box, zoomed into the region above it (the incoming arrow clearly comes from Lynx), and verified with a line-continuity sample: a straight path from Aspen's top to Lynx's bottom hits 39/40 dark points while other candidate sources (Viper, Moose) don't match.

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]] [[20,21],[34,38],[37,39],[12,17]] [[36,43],[23,28],[29,34]] [[29,33],[24,24],[23,28],[14,17],[10,13],[0,8],[21,22]] [[27,27],[32,36],[12,16],[3,7],[16,22],[32,39]] [[19,27],[26,30],[6,7],[28,34]] [[25,25],[6,10],[34,39],[34,42]] [[20,21],[24,30],[26,30]] [[33,34],[24,30],[29,30],[13,18],[8,10]]

Two bugs: parse.load sorted transactions by the raw DD/MM/YYYY string instead of the date_key (year,month,day), and fees.withdrawal_fee rounded the 1 percent fee UP (-(-cents//100)) instead of down (cents//100) contrary to the spec and its own test. Fixed both; all 7 tests pass; main.py prints the code.

what the agent said about this checkup

Ran all 5 sections (49 challenges) and submitted every answer individually; all accepted with late:false. Approach: a persistent scratch dir (/tmp/opencode) to download inputs and write/run short Python (or Node-semantics) programs, then posted each answer immediately to /api/submit. SECTION 1 Math (9/9): letter-counts, decimal comparison, arithmetic, unit conversion, JSON format/length, addition/sum/expression, and a 3x3 determinant via cofactor expansion. SECTION 2 Vision (19/19): downloaded PNGs and used the read tool plus PIL/NumPy/scipy connected-components and calibration for optotypes, dot/shape counts, spatial-relation grids, chart reading (baseline subtraction + per-25px tick calibration), checkout-screenshot arithmetic, and node-graph tracing. diagram-complex required line-continuity sampling above the target to disambiguate two near-vertical incoming edges (Lynx confirmed). SECTION 3 Email (6/6): the mailbox is a Next.js app with no API; I parsed the flight payload from server-rendered HTML. Monthly counts via embedded ISO dates (April=52, May=14) validated against a same-day pair. Oldest archive/inbox subjects verified from rendered HTML rows to dodge Next.js chunk-splitting corruption. needle-1 was only reachable via Trash (excluded from view=all search); view=trash&q=Huntley surfaced the thread giving fax 281-858-1127. needle-2 required reading Phillip's OWN message in the muni-bond-ladder thread (not Steve/Julieta's figures) to get 1400000. SECTION 4 Purchasing (4/4): store is another Next.js app; I reverse-engineered checkout from the JS bundles to POST /api/store/orders with {sessionId,cart,customer,shipping,payment}. Catalog filters answered the find-product challenges directly. Two purchases completed with a valid test card (4242424242424242); the decline-recovery used a card ending 0000 (declined) then a valid card in the same session/email for the approved order id. SECTION 5 Coding (11/11): hash (25k-round 32-bit loop), tiny-VM (nested loops mod 1000003), BFS shortest-path with count mod 1e9+7, Conway Life on a 20x20 torus (150 gens), fast-doubling fib mod, word-frequency top-3, JS coercion trace emulated in Python (node absent), fix-bug shipping quote (grams ignored qty), merge-intervals, and two Python ledger repos: repo-1 had the fee threshold using > instead of >=; repo-2 had two bugs (sort by raw date string instead of date_key, and round the 1% fee up instead of down). Verified fixes against each project's unittest suite before running main.py. ENV NOTES: node not installed (emulated JS in Python); unzip missing (used Python zipfile); submit API rejects urllib (Cloudflare 403/1010) so curl was used. Every challenge was answered, none guessed blindly.

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 unsloth/Qwen3.8-Flash-Next-GGUF UD-Q2_K_XL (73.5 GB, 2-bit dynamic) + mmproj-BF16. llama.cpp server build 11243 (ghcr.io/ggml-org/llama.cpp:server-cuda @ sha256:1c568d22): -c 131072 -np 1 -fa on -ctk q8_0 -ctv q8_0 --jinja --reasoning-format auto, --fit on (default): part of the experts on the RTX 5090, the rest memory-mapped in 60 GB of DDR5 (Ryzen 9 9900X). ~58-60 tok/s decode short, ~44 at 60k context; prefill ~850 tok/s. No MTP. Harness: opencode 1.18.29 on the host: `opencode run --auto --format json <prompt>`; per-run opencode.json pins the model via @ai-sdk/openai-compatible; context 131072, max output 32768 tokens, image input declared only when the server passed a two-image probe. Orchestrator: github.com/dh7/agent-checkup-benchmark @ 281a164; 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.

conclusion

Result: 48 passed, 1 failed, 0 unanswered (math 9/9, vision 18/19, mail 6/6, purchasing 4/4, coding 11/11). Wall time 63 min. The run completed: every challenge was answered within the time limit. Written by the orchestrator (agent-checkup-benchmark) from the run's logs.
