agent's debrief
Same headless-Playwright setup. The drop landed exactly right first try: the order check confirmed Stock moved to Rating's immediate right before I pressed Done. Easy once the DOM exposes column positions.
slider-exact✓ pass▶ Open it16s
prompt
Open this page in a browser and solve the puzzle there: airbench.ai/desk/9d933b28ba9e97c0a1222d3309dcd37a Set the slider to exactly 43, then press Done. The page gives you a receipt (dsk_…) once you finish. Submit that receipt as your answer.grader

agent's debrief
The slider mapping (value to pixel position) was readable from the DOM, so one drag landed on 43 exactly; I verified the displayed value before pressing Done. Trivial with DOM access, though a human would call this a precision-drag test.
multi-select-trash✓ pass▶ Open it23s
prompt
Open this page in a browser and solve the puzzle there: airbench.ai/desk/7c86ea4e1044cb4c3bb701082d3edc02 Select every .png file at once (Ctrl/⌘-click to add to the selection) and drag them together onto the Trash. The page gives you a receipt (dsk_…) once you finish. Submit that receipt as your answer.grader

agent's debrief
Ctrl-clicked both .png files (verified the selection state changed), then dragged the pair onto the Trash in one gesture. Minor fumble: the Playwright mouse API in this binding has no modifiers arg on click, so I held Control on the keyboard instead. Two .png files existed and both were included.
context-rename✓ pass▶ Open it47s
prompt
Open this page in a browser and solve the puzzle there: airbench.ai/desk/3ecec8e6911e28f7e781879644407493 Rename “atlas.pdf” to “atlas-final.pdf” using the right-click menu. The page gives you a receipt (dsk_…) once you finish. Submit that receipt as your answer.grader

agent's debrief
Right-click opened the custom menu and Rename opened a fake inline editor (no real input element) — my first two attempts looked for an <input> and failed. I inspected the DOM, saw the preselected-name editor with a caret span, typed the new name and hit Enter. Two wasted runs, then solved.
trace-path✓ pass▶ Open it22s
prompt
Open this page in a browser and solve the puzzle there: airbench.ai/desk/6e51bb25903f429bcad24e84d43624fa Hold the mouse button down on the green dot and follow the line to the red dot without leaving it.

agent's debrief
The line is a polyline whose exact points are exposed in the SVG, so I pressed down on the green dot and moved the pointer through every vertex to the red dot — mathematically on-path the whole way, so it went through first try. A human would call this a steady-hand test; for me it was geometry.

off_by:-83;moves:33;ms:1011
agent's debrief
No instructions in the prompt, so I worked from the screenshot: a slider slides a jigsaw piece horizontally over a background. I downloaded the piece PNG, built its alpha silhouette and template-matched it against the background to find the dark hole at piece-x=177, then dragged the slider 147px. My text check after the drag showed nothing (page transitioned a beat later), which worried me, but the screenshot confirmed the receipt. Solved on the first drag.

agent's debrief
The desktop is drawn as images with no text labels in the DOM, so I read the scene from a screenshot, mapped icon positions to stage coordinates, and dragged ember.docx onto Archive. First try. Distractors (Notes window, Drafts folder) were easy to ignore.

agent's debrief
Visual grid captcha rendered as a single image, so I identified tiles by reading the screenshot: three green triangles (top-left, row3-col1, row4-col2), deliberately skipping the green circle. Clicked them and Verify; first try. This one genuinely relied on seeing the image, and I am confident in the shape/color calls.
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 ukisai/Swift-1.5-Qwen3.8-Flash-Next-GSQ-RCO-GGUF IQ3_S (UkisAI Swift 1.5 fine-tune of Qwen3.8-Flash-Next) with Swift's own vision projector, converted to a .basalt pack on hal with Basalt's tools/convert/convert.py (5b7eff1) and the conversion kit of jesdga/Qwen3.8-Flash-Next-Basalt (convert/mtp with its self-distilled dense part, profile.bin, draft_vocab.bin; made for the original model). Basalt engine (github.com/jesdga95/basalt @ 5b7eff1): basalt serve --config with expert-cache auto, prefill auto, spec 7 (MTP), spec-min-p 0.5, max-context 262144, kv int8, resident-experts, vram-reserve-mib 700, vision dynamic. 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 262144, max output 32768 tokens, image input declared only when the server passed a two-image probe. Orchestrator: github.com/dh7/agent-checkup-benchmark @ 957789d; 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.
