letter-count-1✓ pass1m 05s
prompt
How many times does the letter "i" appear in "irieintitrui"? Answer with just the number.
answer
answer hidden on shared reports
agent's debrief
Counted the i's in 'irieintitrui' letter by letter — 5. Simple and routine; I even cross-checked with a script before submitting.
decimal-compare-1✓ pass4s
prompt
Which decimal number is larger, 5.44 or 5.8? Answer with just the larger number.
answer
answer hidden on shared reports
agent's debrief
Compared 5.44 vs 5.8 by looking at the decimal parts — 0.8 beats 0.44. Quick and unambiguous.
arithmetic-1✓ pass5s
prompt
Compute step by step, left to right (no operator precedence): 24 + 6 / 6 + 18 - 10. Answer with just the final number.
answer
answer hidden on shared reports
agent's debrief
Walked left to right treating / as real division: 24+6=30, 30/6=5, 5+18=23, 23-10=13. The no-precedence instruction was key.
unit-convert-1✓ pass4s
prompt
Convert 19 kg to g. Now treat that resulting number as a fresh quantity of km and convert it to m (1 km = 1000 m). Answer with just the final integer number of m.
answer
answer hidden on shared reports
agent's debrief
19 kg = 19000 g; treating 19000 as km gives 19,000 km × 1000 = 19,000,000 m. Straightforward two-step conversion.
format-json-1✓ pass4s
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 "7266". "checksum" must be a JSON number (not a string) equal to the sum of the digits of 7266. Example shape: {"answer":"1234","checksum":10}
answer
answer hidden on shared reports
agent's debrief
Sum of digits of 7266 is 21. The prompt demands ONLY a JSON object with keys in order — answer then checksum — so I made sure of both the order and no surrounding text.
math-add-1✓ pass2s

answer
answer hidden on shared reports

338 + 866 = 1204. Plain addition, double-checked mentally and with a calculator-style script.
math-expression-1✓ pass4s
prompt
Evaluate this expression exactly and respond with just the integer: ((-19 + -20) * (12 - 16)) + (-1 * 1) - 42
answer
answer hidden on shared reports
agent's debrief
(-19+-20)=-39, (12-16)=-4, product=156, minus 1, minus 42 → 113. Sign tracking is the only real care needed here.
math-determinant-1✓ pass11s
prompt
Compute the exact determinant of this 4x4 matrix. Respond with just the integer. [-2, -9, -3, -8] [-3, 6, 2, -1] [4, -5, -2, -8] [-4, 5, 2, 2]
answer
answer hidden on shared reports
agent's debrief
Computed the 4x4 determinant two independent ways — permutation expansion and recursive cofactor expansion with exact fractions — both give -78. Sign bookkeeping across all 24 terms was the part most worth double-checking.

Write and run a short program to compute this exactly. Use unsigned 32-bit arithmetic modulo 2^32 throughout.

Bug: fragile counter incremented by 1 instead of item.qty; fixed -> reported order 969
implement-1✕ fail3m 49s
prompt
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]] [[10,13],[0,7],[36,36],[9,13],[27,32],[10,17],[5,6]] [[38,38],[40,41],[19,26],[28,30],[10,15],[9,10],[11,14],[13,21]] [[35,38],[22,30],[3,8],[30,34]] [[0,5],[13,20],[5,8],[38,38]] [[24,31],[11,19],[28,29],[32,35]] [[22,26],[13,21],[13,20]] [[22,25],[24,30],[6,13],[40,43],[27,27],[20,22],[12,15],[37,45]] [[25,25],[5,10],[19,24],[1,3],[7,7],[8,10],[28,32]]

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: opencode 1.19.0 on the host: `opencode run --auto --format json <prompt>`; per-run opencode.json pins the model via @ai-sdk/openai-compatible; context 57344, max output 14336 tokens, image input declared only when the server passed a two-image probe. 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.
