Output D, 1 turnECEvan ChaNov 5Make a pixel art sprite animation of a red panda mail carrier walking, side view. It must be real pixel art: a true 32x32 grid where every pixel is one solid square, no anti-aliasing, at most 8 colours, and a seamless 8-frame walk loop. If an image model is selected for this run, the art must come from it. Deliver the sprite sheet as a PNG, the loop as an animated GIF, and one web page that plays the loop scaled up with nearest-neighbour. It should feel alive the moment it loads.LLMClaude Opus 5.5Gen AI—Skill—SoftwareGoogle Chrome+11.1M tokens·13m 43s00
Output A, 1 turnECEvan ChaNov 5Build a spreadsheet app as one self-contained index.html (no external assets, no network). UI: a visible grid with columns A-Z and rows 1-1000, a formula bar, click a cell to edit, Enter commits, arrow keys move. It should look like a tool someone would actually use. Also expose this exact API on window.Sheet. It must stay in sync with the UI: - set(ref, text): enter text into a cell, as if typed. Empty string clears it. - get(ref): the computed value. A number for numeric results (JS number), a string for text and for errors, "" for empty cells. - getRaw(ref): exactly what was entered. - undo(), redo(): cover set, insertRow, deleteRow and fromCSV. A new edit clears the redo history. - insertRow(n), deleteRow(n): 1-based. Rows shift, and formulas are rewritten as Excel does. Both relative and $absolute references move with their cells. A reference to a deleted single cell becomes #REF! in the formula text (for example "=#REF!"). A range that loses a row shrinks. - toCSV(): RFC 4180 raw text (formulas as typed), rectangular up to the last non-empty row and column, rows joined by \n, no trailing newline. - fromCSV(text): replaces the whole sheet, starting at A1. Handles quoted commas, doubled quotes and newlines inside quotes. Formulas start with "=". Case-insensitive, whitespace ignored. - Operators: + - * / ^ & (text concat), postfix %, parentheses. ^ is right-associative. Unary minus binds tighter than ^, as in Excel, so =-2^2 is 4. - References: A1, $A$1, $A1, A$1. Ranges: A1:B3. - Functions: SUM, AVERAGE, MIN, MAX, COUNT, IF(cond, a, b). Conditions use = <> < > <= >=. - Text in double quotes. - Empty cells are 0 in arithmetic and "" in concat. Range functions skip text and empty cells. Numbers concat in plain form (5 & "x" is "5x"). - Errors, exact strings: #DIV/0!, #REF!, #CYCLE!, #NAME? (unknown function), #VALUE! (text in arithmetic). Errors propagate, including through range functions. Every cell in a cycle, and every cell depending on one, shows #CYCLE!. Fixing the cycle recovers them. - Cells recalculate automatically. With 10,000 filled cells and a SUM over them, editing one input must finish recalculating within 1 second. A dependency chain 1000 cells deep must work. A numeric cell typed as 42 or 3.5 is a number. Anything else not starting with "=" is text.LLMClaude Opus 5.5Gen AI—Skill—SoftwareGoogle Chrome+1596.6K tokens·13m 9s00
Output A, 1 turnECEvan ChaNov 5You are advising the founder of a B2B software company. A buyer has offered 4.0x ending ARR at 2025-12-31, with 20% of the price held back and released only if 2025 net revenue retention (NRR) is at least 110%. The founder wants to know what this offer is really worth and whether to sign. Below is the raw contract export. It has not been cleaned. Use FX at USD per unit: EUR 1.08, GBP 1.27, for all dates. A contract is active on a date if start <= date <= end. "amount" is per billing period unless a note says otherwise.

Output A, 1 turnTtamburinsOct 29Build a stunning interactive 3D “Overengineered Coffee Machine” that runs in the browser: an elaborate miniature Rube Goldberg machine whose entire purpose is to make one tiny cup of espresso. Make it immediately understandable, visually mesmerizing, and satisfying to watch in a short screen recording. The opening frame should show the complete machine with a polished steel marble poised at the beginning of its journey. Create a continuous chain reaction: 1. A steel marble spirals down a brass funnel and exits onto a curved rail. 2. It strikes a lever that releases coffee beans into a miniature grinder. 3. Interlocking gears turn the grinder while a bucket elevator carries the marble to the next level. 4. The marble rolls across a small seesaw, triggering a piston that tamps the coffee. 5. A pressure gauge climbs, a valve turns, and espresso flows into a ceramic cup. 6. A small mechanical arm slides the finished cup onto a presentation platform beneath a warm spotlight. 7. The marble returns to its starting position, and the mechanisms reset for another cycle. Every stage must visibly cause the next. Keep the marble’s path continuous, make the gears mesh convincingly, and ensure objects remain supported by rails, platforms, or mechanical parts throughout the sequence. Art direction Imagine a precision-built kinetic sculpture displayed in a boutique coffee shop. Use brushed brass, walnut, cream ceramic, clear glass, and polished steel, with a restrained orange-red accent for moving controls. Include beautifully modeled details such as bolts, bearings, rail supports, gauge markings, and glass bean hoppers. Use warm studio lighting, soft contact shadows, carefully controlled reflections, and a clean background. Make the materials feel tactile and the construction believable. Give the machine a strong silhouette and arrange its stages so the viewer can follow the action easily. Motion and presentation Choreograph a roughly 20–25 second cycle with a clear beginning, escalating activity, and a satisfying espresso reveal. Mix fast marble runs with slower, weighty mechanical movements and brief moments of anticipation. Use a flattering three-quarter camera angle that keeps the entire mechanism readable. Start the animation automatically. Make the reset part of the choreography so the loop continues without a visible jump or sudden disappearance of objects. Prioritize a spectacular default view that reads well in a portrait screen recording. Keep the machine large in the frame and interface elements small and unobtrusive.LLMClaude Opus 5.5Gen AI—Skill—SoftwareGoogle Chrome+14.7M tokens·40m 44s00
