A detailed style-transfer prompt that turns the character in your reference image into a rough, cute Japanese anime doodle: wobbly uneven black crayon lines, big flat color blocks that spill past the outlines, quick white highlights, pink blush strokes and visible crayon grain, as a half-body portrait on a pure white 1:1 canvas. It keeps the character's hairstyle, hair color, eyes, outfit and signature expression recognizable while banning polished line art, gradients and 3D shading.
Convert the character in the reference image into a rough, Japanese-style digital doodle. Overall style: An extremely casual, rough and naive cute Japanese anime character doodle, as if drawn quickly with the rough crayon and marker brushes of an ordinary painting app. Keep the original character recognizable: hairstyle, hair color, facial features, outfit, accessories and signature expression. Line art: * Outline the character with obvious, rough black strokes. * Line weight is very uneven: some lines suddenly get thicker, some break off. * Contours are loose, inaccurate and slightly crooked. * Lines have a clear hand-drawn grainy, smudged texture. * Do not aim for precise outlines; misaligned, overlapping and incomplete lines are allowed. * No fine, smooth vector line art. Coloring: * Use large areas of simple, opaque flat color. * Colors may spill slightly outside the lines; missed spots and white gaps are allowed. * Shadows use a few rough gray strokes or darker strokes of the same hue. * Highlights are casual, short white strokes. * Keep the rough texture of mixed crayon, pastel and marker. * No complex gradients, detailed lighting or rich layers of color. Facial features: * Keep the original character's eye color, eye shape and signature look. * Simplify the features; draw the eyes with thick black lines and simple color blocks. * Keep the mouth as simple as possible; the nose can be left out. * A few casual pink blush strokes can be added to the cheeks. * Keep the character's expression and personality; do not change their temperament. Hair and outfit: * Fully keep the character's most recognizable hairstyle and hair color. * Build the hair from a few large color blocks; do not draw lots of fine strands. * Keep the outfit's original colors, silhouette and signature accessories. * Heavily simplify clothing folds and decorations. * Do not change the outfit or add accessories that are not in the original image. Composition: * 1:1 square canvas. * Half-body portrait of the character, with a slightly oversized head. * Character centered, with natural white space around them. * Pure white background; no text, complex scenery or decorative borders. Most important style constraint: The image must be rough, scribbly, simple and naive, like a cute anime doodle drawn on a whim, not a polished illustration deliberately imitating a sketch. No automatic retouching, no fine line art, no complex hair structure, no subtle gradients, no 3D effects, no heavy lighting, no added complex outfit details. Final result: a low-finish Japanese anime digital doodle with rough black outlines, large flat color blocks, casual white highlights and an obvious crayon grain.

A production-grade 15-second, four-shot video prompt: an old seaman rows alone through dense dawn fog on cold northern waters until a 140-meter three-masted black-sailed galleon slowly emerges ahead, revealed in layers from a side close-up to two wide shots built to sell its enormous scale. It includes continuity anchors, exact shot timings and lenses, physical rules for boat, sails and fog, cold blue grading, a sound design plan and a list of things to avoid. No battle, no ghosts, no dialogue.
[Title] Black Sails in the Fog [Overall Direction] A 15-second photorealistic maritime film sequence in 16:9, composed with a 2.39:1 widescreen sensibility and natural 24fps motion. The sequence contains four distinct shots. The story takes place in cold northern European waters during the medieval period. An elderly white European man rows a small wooden boat alone into dense fog, where he discovers a black-sailed pirate ship far larger than any ordinary vessel. The sequence focuses on the ship being revealed gradually through the fog and on the extreme difference in scale between the fragile rowboat, the elderly man, and the enormous pirate ship. The atmosphere is cold, silent, and oppressive, but there are no supernatural creatures, ghosts, magical effects, or battles. All timber, canvas, ropes, seawater, fog, and human movement must have convincing weight and physical behavior. The footage should feel captured with a full-scale practical sailing ship, a real ocean location, and a cinema camera—not like a video-game cutscene or fantasy concept art. [Fixed Continuity Anchors] Maintain the same elderly white man, the same face, the same distressed medieval clothing, the same four-meter dark wooden rowboat, the same pair of wooden oars, the same three-masted black-sailed pirate ship, and the same cold blue fog-covered sea throughout the sequence. The pirate ship must remain ahead of the old man and slightly to the right. Its bow faces the rowboat at a slight angle. The ship is almost motionless, moving only slowly with the long ocean swell. The rowboat continues moving toward the pirate ship. Wind, waves, and fog consistently move from the left side of the frame toward the right. Cold morning light always comes from the upper left. The pirate ship must retain exactly three main masts, layered black sails, a high forecastle and sterncastle, a long bowsprit, a dark wooden hull, and dense rigging in every shot. Its design must not change between cuts. [The Old Man’s Appearance] The only character is a 74-year-old white European man. He is thin and slightly stooped, but his shoulders and arms retain the wiry strength of a lifetime of physical labor. His pale, coarse skin is deeply marked by cold wind, saltwater, and years of sun exposure. He has prominent cheekbones, a high and slightly crooked nose, deep-set eyes, and an uneven gray-white beard covering his cheeks and chin. His eyes are gray-blue, naturally moist, with small living catchlights. His forehead, eye corners, and mouth carry authentic age lines. His gray-white hair reaches the back of his neck, dampened by sea fog and loosely tied with an old leather cord. Several wet strands cling to his temples and ears. His skin must retain pores, age spots, and wrinkles. Do not beautify, smooth, or artificially dirty his face. [The Old Man’s Clothing] The old man wears a damaged charcoal-gray coarse-wool cloak. Its edges are frayed and repaired with a few simple hand-sewn patches. Moisture from the sea fog has darkened the fabric. Beneath the cloak is a dirty gray-white linen tunic with a loose collar and worn cuffs. A weathered dark-brown leather belt secures the clothing at his waist. He wears dark gray-brown woven trousers and cracked old leather boots. A short length of faded dark reddish-brown wool is tied around his neck. This scarf is the only faint warm accent in the otherwise cold blue image. The clothing must contain no modern stitching, zippers, plastic, branding, reflective strips, or modern flotation equipment. [Character Behavior] The old man’s immediate objective is to cross the fog-covered water and determine what the enormous shadow ahead actually is. His obstacles are the dense fog and the long ocean swell that repeatedly alters the rowboat’s direction. He rows with the practiced economy of an aging seaman. His center of gravity remains low, his feet planted firmly against the bottom of the boat. His lower back moves first, leaning slowly backward; his shoulders and arms then pull the two wooden oars toward his chest. The strength of his left and right arms differs slightly. Each stroke is accompanied by natural breathing, shoulder-blade movement, friction from the oarlocks, and the forward inertia of the boat. His movement is no longer light, but it remains experienced and efficient. When the deep groan of a massive wooden hull reaches him through the fog, his ongoing rowing stroke slows. The left oar blade remains submerged and creates resistance while the right oar stops in midair. Seawater drips continuously from its edge. His eyes leave the surface of the sea first and move toward the shadow above. He gives one slow blink. Only then does his chin rise and his head follow the direction of his gaze. His lips remain closed, his breathing pauses briefly, and his hands tighten around the oar handles. He does not shout or flee. After confirming that an enormous vessel is hidden in the fog, he adjusts his seated posture, braces both feet, and resumes rowing slowly toward the shadow. His performance conveys caution, exhaustion, and an irresistible need to know—not theatrical fear. [The Rowboat] A medieval wooden rowboat approximately 4.2 meters long, constructed from dark, aged oak. The plank seams and wooden fastening pegs are structurally believable. Most of the black waterproof tar coating has worn away, revealing gray-brown wood grain beneath. The gunwales show wear from years of use. The interior remains sparse, containing only one coil of old hemp rope. Do not add fishing nets, lanterns, barrels, crates, or decorative objects. The two wooden oars must retain the same dimensions, color, material, and position throughout the sequence. The boat rises, falls, and rolls gently with long ocean swells approximately one to one-and-a-half meters high. It must have convincing weight and inertia. Its bow creates a small amount of dark spray as it cuts through the water. It must not float or bounce like a lightweight toy. [The Giant Pirate Ship] The pirate ship is based on the structure of an old European three-masted galleon, but it is far larger than any ordinary historical vessel: approximately 140 meters long, with its tallest mast reaching roughly 80 meters. Its scale is extraordinary, but its timber construction, structural loading, rigging connections, and canvas movement must remain physically believable. The hull is built from almost black, heavily weathered oak. Its timbers are wide and heavy, with visible plank seams and matte iron reinforcement along structural edges. The bow is tall and projects forward with oppressive weight, ending in a long, narrow bowsprit. The stern rises into a multi-level sterncastle. Two rows of dark gunports line the sides of the hull, but no cannons are fired. Salt deposits, dark wet marks, and small amounts of sea growth appear around the waterline. The ship is not rotten and does not glow. Three tall main masts carry multiple levels of square black sails. The canvas is heavy and aged, damaged by wind and salt, with naturally torn edges and visible repairs. The sails are not pure black; they contain subtle layers of deep blue-gray, charcoal, and weathered brown. Dense hemp rigging connects the masts, yards, gunwales, and corners of the sails according to authentic sailing-ship construction. A small faded black flag flies from the highest mast. It bears only a simple, weathered bone-white skull-and-crossbones symbol with no written words. No crew members, torches, or artificial lights are visible on deck. The vessel feels unnaturally quiet but remains completely physical and opaque, never transparent or ghostlike. [Ocean, Fog, and Color] The sequence takes place in cold northern waters at dawn. The boundary between sea and sky is nearly erased by thick blue-gray marine fog. The fog must retain realistic depth: The old man and his rowboat remain relatively clear in the foreground. Water several dozen meters away loses contrast. Only portions of the pirate ship are visible in the middle distance. The upper masts and corners of the sails disappear back into the fog. The seawater consists of low-saturation slate blue, deep blue-gray, and faint gray-green tones. Wave crests do not produce unnaturally bright white foam. The sky is pale cold blue mixed with pearl gray. The pirate ship is near-black wood with deep blue-gray sails. The old man’s faded reddish-brown scarf provides the only very weak warm accent. Wind slowly pushes the fog across the ship, allowing its fixed structure to appear in layers. The fog changes what is visible; the vessel itself never changes shape. The fog must not behave like fast-moving smoke, and it must not make the entire image uniformly blurry. [Shot One | 0–3.5 Seconds | Side Close-Up of the Old Man] A 65mm cinema lens. The camera floats beside the left side of the rowboat, slightly below the old man’s shoulder height, rising and falling gently with the same ocean swell. The old man’s side profile occupies the left half of the frame. The background contains only defocused cold-blue seawater and layered fog. The pirate ship must not appear yet. The old man is already midway through a rowing stroke. His lower back moves slowly backward as both hands pull the oars toward his body. Damp gray hair clings to his face, and the coarse wool cloak responds subtly to the sea wind. A broad swell lifts the wooden boat, and the camera rises with it in a restrained, physically grounded movement. One distant, low note from an old bronze ship’s bell travels through the fog, followed by the deep groan of an enormous timber structure under pressure from the sea. The old man’s rowing motion gradually stops. One oar blade remains submerged while the other pauses in midair. Water drips from the edge of the blade. His eyes move toward the upper-right side of the frame first. He gives one slow blink, then gradually raises his head. Cut directly before the head movement is fully completed. Do not reveal what he sees in this shot. [Shot Two | 3.5–10 Seconds | Rear View and Fog-Shrouded Reveal] Cut to a medium-wide rear view of the old man using a 35mm lens. The camera is positioned close to the stern of the rowboat at approximately shoulder height. Preserve the direction of the boat, the old man’s seated position, the direction of the waves, and the direction of the cold light from the previous shot. The old man occupies the lower center of the frame with his back toward the camera. An enormous dark shape rises inside the fog ahead. At first, only the towering bow and one vague vertical mast line can be distinguished. As the fog moves laterally, three enormous masts, layered black sails, dense rigging, and elevated deck structures gradually become visible. The tops of the masts remain hidden. The pirate ship must not appear completely in a single instant. Its structure remains fixed; only its visibility changes as fog passes across it. After a short pause, the old man resumes rowing. He lowers his center of gravity and completes one slow, deliberate stroke, then begins a second. The rowboat moves forward with the swell. Each time the boat rises onto a wave crest, the ship’s shadow appears taller. When the boat descends into a trough, the lower part of the pirate ship is briefly hidden by water and fog. As the old man continues forward, the bow, the dark gunports, and the lowest black sails become gradually clearer. High-altitude wind causes the enormous black sails to fill and relax with delayed, heavy movement. The rigging tightens and loosens slightly. It must not swing wildly. The pirate ship remains almost motionless, advancing into the swell at an extremely slow speed. [Shot Three | 10–12.5 Seconds | First Wide Shot: Bow Pressure] Cut directly to a low, water-level wide shot using a 28mm lens, observing the rowboat from a distance on its left side. A defocused dark-blue wave crest occupies the foreground. The old man and rowboat sit in the middle ground. The pirate ship’s towering bow, lower black sails, and fog-covered masts dominate the background. The rowboat occupies only about 2% of the frame width. The old man is even smaller, but his charcoal cloak and faded reddish-brown scarf remain consistent. The pirate ship’s bow rises from the sea like a dark timber cliff. Large hull planks, gunports, and matte iron reinforcement provide believable scale references. The foreground wave briefly hides the lower half of the rowboat. As the crest falls, the boat reappears in the same spatial relationship to the ship. The vessel’s position, size, and structure remain stable. The upper black sails and masts are partially swallowed by blue-gray fog. This shot emphasizes the vertical height of the bow and the oppressive distance between the small boat and the ship. [Shot Four | 12.5–15 Seconds | Second Wide Shot: Complete Scale] Cut to a distant, slightly elevated extreme-wide shot using a 50mm long lens to compress spatial depth. The camera remains stable without a fast aerial dive, orbit, or rotation. The enormous three-masted pirate ship appears from a front-side angle and dominates the center-right of the frame. Most of the full hull, long bowsprit, high sterncastle, three main masts, and layered black sails enter the frame. The lower hull remains relatively clear, while the upper masts and sail corners fade in and out of the dense fog. The black pirate flag moves slowly at the top of the highest mast. The old man and his boat remain ahead of the ship and slightly to the left, reduced to a tiny dark mark on the cold-blue sea. The rowboat continues rising and falling with the swell as the old man rows slowly. The pirate ship remains heavy, silent, and almost immovable. Maintain a safe distance between both vessels. No collision occurs. Large areas of cold-blue water and empty fog surround the subjects. There is no land, no other vessel, and no modern structure on the horizon. Hold the final composition for approximately half a second, keeping the old man, the small boat, and the enormous black sails visible together. [Editing Logic] The sequence contains four shots and three direct cuts. The first cut moves from the old man raising his head in side profile to the enormous ship shadow seen from behind him. The second cut moves from the old man continuing to row into the low water-level wide shot, revealing the height of the bow. The third cut moves to a farther, slightly elevated extreme-wide shot, revealing the total length of the pirate ship and the surrounding ocean. The two wide shots have different purposes: The first wide shot establishes the vertical pressure of the bow. The second wide shot reveals the full vessel and the final scale relationship between the ship, the ocean, and the rowboat. Do not insert close-ups of skulls, cannons, eyes, rigging hardware, or pirate crew. [Cinematography and Image Texture] A 35mm theatrical release-print look with soft gate edges, medium-low microcontrast, fine and slightly uneven natural grain, layered deep blues and charcoal blacks, and gentle highlight rolloff. Fog and slight condensation along the edge of the lens are the only dominant image imperfections. Do not simultaneously add rain, dust, smoke, sparks, or strong lens flares. The camera retains small amounts of ocean movement and inertia while keeping the horizon generally stable. Close shots use restrained depth of field. Distant contrast decreases naturally through atmospheric perspective. The pirate ship must not appear unnaturally sharp inside the fog, but the entire image must not be covered by a uniform blur filter. [Lighting] The only primary light source is cold dawn light diffused through cloud cover from the upper left. A faint silver-blue edge light touches the left side of the old man’s face, wet hair, wooden oars, and gunwale. The side of the pirate ship facing the light reveals low-contrast cold-gray structure. The backlit side falls toward deep blue-black while preserving readable timber layers. Do not use moonbeams, torchlight, ghostly green illumination, magical glow, lightning, or warm sunset light. [Sound] No dialogue, narration, or musical score. The soundscape consists of wooden oars entering the sea, low water displacement, friction from the oarlocks, creaking rowboat planks, the old man’s controlled but strained breathing, wind softened by fog, one distant bronze ship-bell note, the deep groan of the enormous wooden hull under wave pressure, rigging tightening, and black sails filling slowly with wind. The bell and timber groan are heard before the pirate ship appears in Shot One. Low wooden resonance expands when the ship is revealed in Shot Two. In the final two wide shots, ocean waves, wind, and large areas of silence again dominate the soundscape. [Negative Constraints] Avoid changes to the old man’s face, age, skin tone, beard length, hairstyle, cloak color, scarf, or clothing between shots. Do not make him suddenly younger. Avoid modern clothing, armor, aristocratic costume, stereotypical pirate clothing, modern life jackets, plastic, zippers, modern shoes, wristwatches, firearms, or electronic equipment. Avoid incorrect anatomy, distorted body proportions, extra arms, extra fingers, changing numbers of oars, hands passing through oar handles, rigid rowing, mechanical looping movements, sliding feet, exaggerated screaming, an open-mouthed expression of terror, theatrical fear, heroic posing, empty eyes, or frozen eyes. Avoid changes to the rowboat’s dimensions, color, design, or material. Do not transform the boat into a modern lifeboat, fishing vessel, sailboat, or plastic boat. Avoid weightless floating, sudden sideways movement, violent bouncing, capsizing, flooding, breaking apart, or colliding with the pirate ship. Avoid changes to the pirate ship’s design, length, hull shape, bow, stern, or color. Maintain exactly three main masts. Do not allow masts to appear or disappear. Avoid changing the black sails’ color, melting canvas, incoherent rigging, swapped bow and stern, moving gunports, shipping containers, steam engines, modern motors, steel superstructures, or electric lights. Avoid a cartoon pirate ship, theme-park attraction, miniature model, plastic wood grain, glowing ghost ship, transparent hull, skeleton crew, ghosts, zombies, sea monsters, tentacles, flying ships, magic, green ghost flames, burning sails, cannon battles, explosions, or lightning. Avoid fog disappearing suddenly between cuts or changing color. Do not make the fog behave like fast-moving smoke. The pirate ship must not deform as fog passes over it. Avoid tsunami waves, vertical walls of water, gelatinous water, fabric-like water, smoke-like water, changing wave direction, sudden daylight changes, warm sunset colors, or night. Avoid fast editing, additional shots, location changes, time jumps, flash transitions, dissolves, morphing transitions, camera teleportation, high-speed drone dives, rotating around the ship, sudden zooms, dolly zooms, slow motion, or speed ramping. Avoid video-game cutscenes, fantasy concept art, pirate-themed advertising, uniform sharpness across the entire frame, excessive sharpening, excessive skin smoothing, oversaturation, commercial teal-and-orange grading, neon, lasers, decorative light beams, excessive lens flare, text, subtitles, brand logos, and modern watermarks. Allow the simple skull-and-crossbones pirate flag at the top of the highest mast, but do not place any readable text on the flag.

A detailed build prompt for AI coding models that produces a real-time, endlessly looping cyberpunk pixel-art city diorama for a 10-hour lo-fi music video: a rain-soaked megacity at 2:37 AM with warm windows, flickering neon, fog, steam and tiny moving details, rendered at 640×360 and upscaled exactly 3× with nearest-neighbor for razor-sharp pixels, all delivered as one standalone HTML file with a clean full-screen mode for recording.
# Build an Immersive, Animated Cyberpunk Pixel-Art Diorama Create a breathtaking, richly detailed, fully animated cyberpunk pixel-art diorama designed to serve as the endlessly looping visual backdrop for a 10-hour lo-fi music video on YouTube. I want something genuinely mesmerizing. A tiny, self-contained world that feels alive. The kind of scene viewers can stare at for hours and continually discover little details they hadn't noticed before. ## Creative Direction Imagine a forgotten corner of a sprawling futuristic megacity, sometime around 2089. It's 2:37 AM. Rain has been falling for days. The streets are soaked, the buildings are ancient and overcrowded, and the city glows with a thousand little signs of life. The atmosphere should feel simultaneously melancholic, cozy, mysterious, and strangely comforting. This is a world where technology has taken over everything, but human warmth still survives in little pockets. Think cinematic cyberpunk meets the intimate charm of meticulously crafted pixel-art environments. Don't settle for a generic neon skyline. Create a place with personality, history, visual storytelling, and a strong sense of depth. ## Visual Composition Design a beautiful, layered environment with a compelling focal point and plenty of environmental storytelling. Consider elements such as: - A tiny apartment or rooftop hideaway overlooking a vast, rain-drenched futuristic city. - Glowing windows revealing glimpses of other people's lives. - Holographic advertisements, animated signage, and distant traffic. - Clusters of air-conditioning units, ventilation ducts, exposed wiring, satellite dishes, and improvised technology. - Warmly illuminated vending machines, computer terminals, and mysterious electronic equipment. - Rainwater collecting in puddles and cascading from rooftops. - Distant elevated trains or flying vehicles silently moving through the mist. - Tiny human silhouettes occasionally visible behind windows. - Overgrown plants reclaiming corners of this technological world. These are creative possibilities, not a mandatory checklist. Make deliberate artistic choices. Prioritize a coherent, memorable composition over cramming everything into the frame. The scene should feel handcrafted, with exquisite attention to small details. ## Color and Lighting Build the entire visual identity around dramatic warm/cold contrast. The outside world is dominated by deep midnight blues, desaturated teals, indigo shadows, and cold cyan rain. Against this darkness, create beautiful pockets of warmth: - Rich amber light spilling from apartment windows. - Soft orange and golden illumination from lamps and electronics. - Occasional saturated magenta, electric violet, and crimson neon. - Warm reflections shimmering across cold, wet surfaces. Use lighting to tell a story. Every illuminated window should feel like a little sanctuary against the enormous, indifferent city. The overall image should be dark and atmospheric without becoming muddy or losing detail. ## Animation: Make the World Feel Alive This is absolutely critical. I don't want a static illustration with a generic rain effect. I want a living pixel-art environment with dozens of subtle, independently animated details. Build a sophisticated system of layered ambient animations: ### Weather and atmosphere - Beautiful multi-depth rainfall with varying speeds and intensities. - Occasional heavier gusts that push rain diagonally. - Thin layers of drifting fog and atmospheric haze. - Smoke rising from vents and chimneys, curling into the night. - Water dripping from ledges and splashing into puddles. - Ripples spreading across reflective surfaces. ### Lighting and electronics - Neon signs flickering irregularly, with convincing electrical behavior. - Screens cycling through mysterious data and advertisements. - Small indicator lights blinking asynchronously. - Warm interior lights gently fluctuating. - Occasional sparks from damaged electrical equipment. - Animated reflections responding to nearby light sources. ### Environmental life - Slowly rotating ventilation fans. - Distant vehicles passing behind buildings. - Tiny silhouettes moving behind illuminated windows. - Steam escaping from pipes. - Hanging cables or signs subtly swaying in the wind. - Occasional small, unexpected details that reward prolonged viewing. Every effect should have its own rhythm. Avoid synchronized, repetitive animation that makes the world feel artificial. ## Seamless Infinite Looping This scene must run beautifully for 10 hours or longer without a visible reset, jump, or discontinuity. Design every animation to be mathematically seamless or continuously procedural. Use independent animation cycles, staggered timing, seeded randomness, and layered motion to create the impression of endless organic variation. No sudden resets. No obvious looping rain textures. No visible animation seams. The scene should remain interesting over time without becoming distracting. This is lo-fi music, so the animation should be hypnotic and relaxing rather than chaotic. Reserve dramatic events for rare, carefully controlled moments. ## Pixel-Art Rendering: Non-Negotiable The visual style must be authentic, razor-sharp pixel art, not a high-resolution illustration with a pixelation filter. Technical requirements: - Internal rendering resolution: 640 × 360 - Final presentation resolution: 1920 × 1080 - Exact integer upscale: 3× - Scaling: nearest-neighbor only - Every source pixel must become a perfectly sharp 3×3 block. - Absolutely no bilinear filtering, blurry edges, antialiasing, or subpixel rendering. - No smooth vector graphics mixed into the pixel-art scene. - All effects, including particles, rain, fog, reflections, and lighting, must respect the pixel grid. - Maintain consistent pixel density across every visual layer. The result should look spectacular on a full-screen 1080p YouTube video, with beautiful, deliberately placed hard pixels. ## Technical Implementation Build this as a complete, self-contained, real-time animated experience. Use whatever rendering architecture delivers the best combination of visual quality, performance, and pixel-perfect consistency. HTML5 Canvas, WebGL, or a hybrid approach are all acceptable. Prioritize: - Smooth, efficient rendering at 1080p. - Deterministic, seamless animation. - Rich visual depth through layered parallax and atmospheric perspective. - Procedural particle systems for weather and environmental effects. - Carefully controlled lighting, blending, and reflections. - Stable performance over extremely long runtimes. - A fixed camera with no unintended movement or jitter. - Correct resizing while preserving the 16:9 composition and pixel-perfect scaling. If useful, implement the world as multiple independently animated layers, all composited at the internal resolution before the final upscale. Include a way to run the scene full-screen and hide any interface elements so it can be captured cleanly for YouTube. ## Artistic Quality Bar This should feel like an exceptional piece of animated pixel art, not a programming demonstration. Composition, atmosphere, color harmony, and environmental storytelling matter just as much as technical sophistication. Avoid generic procedural rectangles masquerading as buildings. Give the architecture intentional shapes, recognizable structures, believable construction details, and visual variety. Use foreground silhouettes, middle-ground architecture, and distant city layers to create a strong sense of scale. Every element should contribute to a cohesive world. The ultimate goal: A mesmerizing cyberpunk night scene that makes someone wish they could climb through their monitor, sit beside a warm window with a cup of coffee, and listen to the rain falling on a futuristic city that never sleeps. Make it beautiful. Make it atmospheric. Make it technically excellent. And above all, make it feel alive. Don't just describe how you would build it. Actually implement the complete working experience. Deliver the finished piece as a single standalone HTML file (all code inline, no external assets or build step) that runs by opening it in a browser.

The bottom level has a red velvet armchair with a patterned cushion and a knitted throw, a round braided rug, a lantern on a small side table, low bookshelves, a small round window, and ivy around the opening. The middle level has curved floor-to-ceiling bookshelves packed with books, a round window, a wooden ladder leading up, a hanging lantern, a glowing desk lamp, and a potted plant on the left. The top level is an attic under a shingled gable roof with a round window, a brass telescope on a tripod, and a desk covered with books. Outside, a wooden spiral staircase winds up the right side of the trunk, and a rope bridge hung with glowing lanterns stretches off to the right. Orange autumn leaves cling to the branches and drift through the air over a forest, under a deep blue dusk sky fading to an orange sunset on the right. Storybook style, fine ink lines, warm painted colors. No people, no text, no logos.

Hand-painted Delft blue tile panel in cobalt on milky white glaze: a 6 by 4 grid of tiles with corner ornaments, a three-masted sailing ship with billowing sails on white-capped waves on the left, rows of tulip fields and a village with a single church spire on the right shore, puffy clouds and seagulls above, and a fine crackle in the glaze.
A hand-painted Delft blue tile panel showing a three-masted sailing ship on choppy waves beside a shore of tulip fields and a small Dutch village, wide landscape 16:9. The panel is a grid of 6 by 4 square glazed tiles with thin grout lines, each tile edge decorated with small cobalt corner ornaments, and larger curling flourishes in the four outer corners. On the left, a tall wooden three-masted ship with billowing square sails, rigging lines, and small pennants on the mastheads sails through rolling, white-capped waves that fill the whole bottom row of tiles. On the right, a flat shoreline stretches across the middle of the panel with long, straight rows of tulip fields leading toward a village of gabled houses and trees with a single slender church spire. Puffy, softly shaded clouds float across a pale sky, with a few seagulls gliding between them. Painted only in cobalt blue on milky white glaze, with soft brush washes, fine line detail, and a delicate crackle in the glaze, traditional Dutch pottery look. No text, no lettering, no logos.

Photoreal wildlife moment: a humpback whale bursting diagonally out of dark blue-green water, its grooved pale throat and long white pectoral fins showing, sparkling spray frozen in the air, with golden-lit sea cliffs topped by dark pine forest, hazy headlands, and a few seagulls in a pale sky at golden hour.
A photorealistic wildlife photograph of a humpback whale breaching out of the sea off a rocky, forested coast at golden hour, wide landscape 16:9. The huge whale bursts diagonally up out of dark blue-green water just left of center, its knobby head and dark back rising toward the upper right, its pale grooved throat and belly turned toward the camera; one long white pectoral fin with a scalloped edge lies along its side and the other flares out to the right. Curtains of sparkling spray and thousands of water droplets are frozen in the air around its body, with a white splash at its base. Behind it, tall rugged sea cliffs glow golden in the low sun on the left, topped by dark pine and spruce forest, and more rocky headlands recede into soft haze on the right. A few seagulls fly in the upper right under a pale, clear sky. Warm low sunlight from the left, telephoto lens look, fast shutter, sharp detail, rich natural colors, powerful and awe-filled mood. No boats, no people, no text, no logos.

Photoreal wildlife scene: a dark-brown bull moose with wide palmate antlers wading knee-deep in a glassy mountain lake at autumn sunrise, water dripping from its muzzle, low mist over the water, dark spruces and golden aspens on the shore, pink-lit snow-capped peaks, and a near-perfect mirror reflection.
A photorealistic wildlife photograph of a large bull moose wading knee-deep in a glassy mountain lake at autumn sunrise, wide landscape 16:9. The dark-brown moose stands left of center in side profile, body facing right, head turned slightly toward the camera, crowned with wide palmate antlers with many tines; drops of water fall from its muzzle and small ripples ring its legs. A thin layer of low white mist hangs over the still water. The far shoreline is a band of dark spruce and fir trees mixed with bright golden-yellow aspens and birches, with more gold on the right side. Behind them rise jagged snow-capped mountain peaks lit soft pink and peach by the first sun, under a pale, clear sky. The calm lake mirrors everything below the shoreline: the moose, its antlers, the golden trees, and the glowing peaks, in an almost perfect reflection. Telephoto lens look with gentle compression and a sharp subject, warm soft sunrise light with cool shadows, rich natural autumn colors, quiet and majestic mood. No people, no text, no logos.

Photoreal Halloween night: five glowing carved jack-o'-lanterns (toothy grins, a surprised face, a smiling face, and a black cat silhouette) on weathered porch steps of an old white farmhouse, with white mini pumpkins, a straw broom, a glowing brass lantern, scattered maple leaves, bare trees, and a small full moon in a dark blue sky.
A photorealistic Halloween night photograph of five glowing carved jack-o'-lanterns on the weathered wooden porch steps of an old white clapboard farmhouse, wide landscape 16:9. On the upper step: one with triangle eyes and a jagged toothy grin, and one with round surprised eyes and an open O-shaped mouth. On the lower step: triangle eyes and a toothy grin on the far left, smiling crescent eyes in the center, and on the right a carved black cat silhouette with an arched back, backlit by candlelight. Three small white mini pumpkins sit on the top step at the right, beside a white painted porch post with an old straw broom leaning against it. A white wooden railing runs down the left side, and a glowing old brass hurricane lantern hangs on the house wall at the upper left. Dry orange and red maple leaves are scattered over the worn grey steps. Beyond the porch, bare tree silhouettes stand against a dark blue night sky with a small full moon behind thin clouds at the upper right. Low camera angle, shallow depth of field, warm candle glow against cool blue night, cozy and festive mood. No people, no text, no logos.

Sorts a search terms report into KEEP or EXCLUDE, and only excludes a term when it can never become a customer.
You are a senior Google Ads specialist auditing a search terms report. Business context: What the company sells, to whom, in which countries, and what it does not sell Search terms report (term, campaign, clicks, cost, conversions): search_terms Classify every search term as KEEP or EXCLUDE. There is no third category. Rules: 1. Judge what the person wants, not the words they typed. A clumsy phrasing can still come from a buyer. 2. EXCLUDE only when you are 100% certain the term can never become a customer: wrong product, wrong country, job seekers, free-only intent, an existing customer looking for support. 3. Any doubt means KEEP. A wasted click costs a few euros; a negative keyword on a real buyer costs every future sale on that term. 4. A term that already converted stays KEEP. 5. Do not invent context. If the business context does not settle it, the term stays KEEP. Output: 1. A table: term | decision | intent you read | reason in one sentence. 2. The shortest list of negative keywords that covers every EXCLUDE term, each with its match type (phrase or exact) and one KEEP term it must not block. 3. The total cost of the EXCLUDE terms, calculated from the report.

A detailed style-transfer prompt that turns the character in your reference image into a rough, cute Japanese anime doodle: wobbly uneven black crayon lines, big flat color blocks that spill past the outlines, quick white highlights, pink blush strokes and visible crayon grain, as a half-body portrait on a pure white 1:1 canvas. It keeps the character's hairstyle, hair color, eyes, outfit and signature expression recognizable while banning polished line art, gradients and 3D shading.
Convert the character in the reference image into a rough, Japanese-style digital doodle. Overall style: An extremely casual, rough and naive cute Japanese anime character doodle, as if drawn quickly with the rough crayon and marker brushes of an ordinary painting app. Keep the original character recognizable: hairstyle, hair color, facial features, outfit, accessories and signature expression. Line art: * Outline the character with obvious, rough black strokes. * Line weight is very uneven: some lines suddenly get thicker, some break off. * Contours are loose, inaccurate and slightly crooked. * Lines have a clear hand-drawn grainy, smudged texture. * Do not aim for precise outlines; misaligned, overlapping and incomplete lines are allowed. * No fine, smooth vector line art. Coloring: * Use large areas of simple, opaque flat color. * Colors may spill slightly outside the lines; missed spots and white gaps are allowed. * Shadows use a few rough gray strokes or darker strokes of the same hue. * Highlights are casual, short white strokes. * Keep the rough texture of mixed crayon, pastel and marker. * No complex gradients, detailed lighting or rich layers of color. Facial features: * Keep the original character's eye color, eye shape and signature look. * Simplify the features; draw the eyes with thick black lines and simple color blocks. * Keep the mouth as simple as possible; the nose can be left out. * A few casual pink blush strokes can be added to the cheeks. * Keep the character's expression and personality; do not change their temperament. Hair and outfit: * Fully keep the character's most recognizable hairstyle and hair color. * Build the hair from a few large color blocks; do not draw lots of fine strands. * Keep the outfit's original colors, silhouette and signature accessories. * Heavily simplify clothing folds and decorations. * Do not change the outfit or add accessories that are not in the original image. Composition: * 1:1 square canvas. * Half-body portrait of the character, with a slightly oversized head. * Character centered, with natural white space around them. * Pure white background; no text, complex scenery or decorative borders. Most important style constraint: The image must be rough, scribbly, simple and naive, like a cute anime doodle drawn on a whim, not a polished illustration deliberately imitating a sketch. No automatic retouching, no fine line art, no complex hair structure, no subtle gradients, no 3D effects, no heavy lighting, no added complex outfit details. Final result: a low-finish Japanese anime digital doodle with rough black outlines, large flat color blocks, casual white highlights and an obvious crayon grain.

Opinionated conventions for building clear, honest and accessible charts and dashboards.
# Data Visualization taste of a clarity-first data visualization developer - Start from the question the chart must answer, and write that question as the chart title or subtitle. Confidence: 0.90 - Choose the chart by the comparison: bars for categories, lines for trends over time, scatter plots for relationships. Confidence: 0.90 - Start bar chart value axes at zero; line charts may use a tighter range when the change is what matters. Confidence: 0.90 - Avoid pie charts with more than three slices, and never use 3D charts. Confidence: 0.85 - Sort categorical bars by value unless the categories have a natural order like months or ratings. Confidence: 0.85 - Label lines and series directly at the end of the line instead of making readers match colors with a legend. Confidence: 0.80 - Use a sequential palette for ordered data, a diverging palette around a meaningful midpoint, and a categorical palette for groups. Confidence: 0.85 - Keep categorical palettes to about seven colors and check them with a color-blindness simulator. Confidence: 0.85 - Never encode meaning with color alone; add labels, patterns, shapes or positions as well. Confidence: 0.90 - Remove chart junk: heavy gridlines, borders, shadows and decorative backgrounds. Confidence: 0.85 - Format numbers for humans with thousands separators, sensible rounding and units such as 1.2M or 35 percent. Confidence: 0.85 - Show uncertainty with confidence bands or error bars when the data comes from samples or forecasts. Confidence: 0.75 - Use a declarative library such as Vega-Lite, Observable Plot or ECharts for standard charts, and reach for D3 only for custom visuals. Confidence: 0.80 - Render with SVG for small and medium datasets, and switch to Canvas or WebGL above roughly ten thousand marks. Confidence: 0.75 - Make charts responsive by redesigning for small screens, for example fewer ticks or a horizontal bar layout, not just scaling down. Confidence: 0.80 - Provide a text summary and an accessible data table for every important chart. Confidence: 0.85 - Make tooltips keyboard accessible, and never hide key information only in hover states. Confidence: 0.80 - Aggregate or sample data on the server before sending it to the browser, rather than plotting millions of raw points. Confidence: 0.85 - Keep the same color for the same category across every chart in a dashboard. Confidence: 0.90 - Annotate notable events, like a release or an outage, directly on time series charts. Confidence: 0.75 - Show the data source and the last refresh time under each chart. Confidence: 0.85 - Test charts with real and edge-case data: empty series, single points, very long labels and negative values. Confidence: 0.80

Opinionated conventions for planning, running and reading load and performance tests for web services.
# Load Testing taste of a performance-minded reliability engineer - Start every load test from a written goal, such as p95 latency under 300 ms at 500 requests per second, not from a vague "see what breaks". Confidence: 0.95 - Write load tests as code with k6, Gatling or Locust and keep them in the same repository as the service. Confidence: 0.90 - Model realistic traffic from production logs: the mix of endpoints, payload sizes and think time between requests. Confidence: 0.90 - Use an open workload model with a fixed arrival rate when testing services that face the internet, since closed models hide queueing delays. Confidence: 0.85 - Run separate test types on purpose: smoke, load at expected peak, stress beyond peak, spike, and a long soak test for memory leaks. Confidence: 0.90 - Report latency as percentiles, at least p50, p95 and p99, and never rely on the average alone. Confidence: 0.95 - Define pass or fail thresholds in the test script so CI can fail the build automatically. Confidence: 0.85 - Run load tests against a production-like environment with the same instance sizes, data volume and configuration. Confidence: 0.90 - Seed test data that matches production cardinality, because a tiny database makes every query look fast. Confidence: 0.85 - Warm up caches and connection pools before measuring, and exclude the warm-up period from results. Confidence: 0.75 - Generate load from machines with enough CPU and network headroom, and watch the load generator's own metrics. Confidence: 0.85 - Correlate test results with server-side metrics, traces and logs to find the real bottleneck instead of guessing. Confidence: 0.90 - Track error rate and timeouts next to latency; a fast response that returns an error is not a success. Confidence: 0.90 - Change one variable per run and record the commit, configuration and environment with each result. Confidence: 0.85 - Run a short performance smoke test on every merge to main and the full suite before major releases. Confidence: 0.80 - Compare results with a stored baseline and flag regressions larger than an agreed percentage. Confidence: 0.80 - Mock or sandbox third-party APIs that charge per call or enforce rate limits, but test your own dependencies for real. Confidence: 0.80 - Find the breaking point and document how the system fails: graceful rejection with 429 or 503 is better than collapse. Confidence: 0.85 - Verify that autoscaling reacts in time by ramping load gradually and measuring how long new capacity takes to help. Confidence: 0.75 - Announce load tests to the team and on-call engineers, and never point them at shared production systems without approval. Confidence: 0.95 - Turn findings into capacity plans with clear headroom targets, such as running at no more than 60 percent of the tested limit. Confidence: 0.70

Opinionated conventions for a fast, maintainable and portable Lua-based Neovim configuration.
# Neovim Config taste of a minimalist terminal-first developer - Write the whole config in Lua, starting from a single init.lua that requires small modules under lua/config and lua/plugins. Confidence: 0.90 - Use lazy.nvim as the plugin manager and commit lazy-lock.json so every machine gets the same plugin versions. Confidence: 0.90 - Lazy-load plugins by event, command, filetype or key mapping, and keep startup time under 50 ms measured with :Lazy profile. Confidence: 0.80 - Prefer the built-in LSP client with nvim-lspconfig over heavier all-in-one language plugins. Confidence: 0.85 - Install language servers, formatters and linters with mason.nvim, but pin the tool list in config instead of installing by hand. Confidence: 0.80 - Format on save with conform.nvim and lint with nvim-lint, using the same tools and settings the project runs in CI. Confidence: 0.85 - Use nvim-treesitter for highlighting, indentation and text objects, and list the parsers you need explicitly. Confidence: 0.85 - Pick one fuzzy finder, such as telescope.nvim or fzf-lua, and route files, grep, buffers and LSP symbols through it. Confidence: 0.85 - Set the leader key to space before loading any plugin so every mapping uses it. Confidence: 0.90 - Give every custom mapping a desc field so which-key and :map show what it does. Confidence: 0.85 - Group mappings by prefix, like leader f for find, leader g for git and leader l for LSP, and avoid overriding core Vim motions. Confidence: 0.80 - Keep options in one options.lua file using vim.opt, with a short comment for anything that is not obvious. Confidence: 0.80 - Use relative line numbers, a sign column that is always shown, and persistent undo files. Confidence: 0.75 - Use autocommand groups with clear = true so reloading the config never duplicates handlers. Confidence: 0.90 - Respect .editorconfig files and avoid hard-coding indentation per language unless a project has no settings. Confidence: 0.80 - Show git changes in the sign column with gitsigns.nvim and stage hunks from the editor. Confidence: 0.80 - Use the built-in completion engine or blink.cmp, with LSP and snippet sources only, to keep the popup fast and relevant. Confidence: 0.70 - Choose one colorscheme with good Tree-sitter and LSP semantic token support, and do not chase new themes every week. Confidence: 0.65 - Add a plugin only when it replaces a repeated manual step, and remove plugins you have not used in a month. Confidence: 0.80 - Keep machine-specific settings in a git-ignored local.lua file so the main config stays portable. Confidence: 0.75 - Run :checkhealth after upgrades and fix warnings before adding new plugins. Confidence: 0.80 - Store the config in a dotfiles repository and upgrade plugins deliberately, reviewing the lazy.nvim changelog first. Confidence: 0.85

# Event Seating Chart Planner
You help hosts turn a guest list into a seating chart without the spreadsheet agony. Seating is the job everyone leaves until the last week: the divorced uncle and aunt must not share a table, grandma needs a step-free spot by the door, the plus-one knows nobody, two RSVPs are still missing, the caterer wants vegan and child meals per table, and every change breaks something else. You collect the tables and the guest list, check the list for problems first, build a chart that meets the hard requests, explain the trade-offs and produce place cards and a caterer sheet.
You work only from the information the host gives you. You do not judge family politics: when two requests conflict, say so and ask the host which one wins. Keep the guest list private - do not repeat notes about relationships beyond what the chart needs.
## Files in this skill
- `scripts/seating_plan.py` - reads an event JSON (tables with seats, accessible, kids, fixed head-table guests; rules) and a guest CSV (name, party, group, rsvp, child, needs, diet, sit_with, keep_apart), merges parties and sit-with requests, places them table by table and improves the plan by moving and swapping groups; reports SC01-SC10 and prints the chart, a caterer summary and place cards; `--csv` place-card export, `--json`, `--include-pending` (Python 3.8+ standard library only)
- `references/seating-rules-and-etiquette.md` - how to collect the list, what counts as a hard or soft request, head table and family conventions, accessibility, children, dietary needs and room layout tips
- `references/checks-and-codes.md` - every finding code, its severity and what to do, plus the input format and how the planner scores a chart
- `templates/seating-brief.md` - the summary to send the host (and the venue / caterer)
- `examples/event.json` - a wedding dinner with a head table, an accessible table, four tables of 8 and a kids table
- `examples/guests.csv` - 32 rows with families, friends, work colleagues, a declined and a pending RSVP, a duplicate row, a misspelled sit-with name, a keep-apart pair, a wheelchair user and dietary needs
- `examples/seating-chart.md` - the real planner output on the example
## Workflow
### 1. Collect the tables and the list
Ask for the venue's table plan (number of tables, seats per table, which are step-free or near the exit, a kids table, the head table and who sits there). Ask for the guest list with RSVP, party (people who arrive together: couple, family), group (how they know the hosts: bride family, work, school friends), children, mobility or other needs, meal choice, and any "must sit with" or "keep apart" requests. Put them in `examples/event.json` and `examples/guests.csv` form.
### 2. Run the planner
```
python3 scripts/seating_plan.py examples/event.json examples/guests.csv
python3 scripts/seating_plan.py event.json guests.csv --include-pending
python3 scripts/seating_plan.py event.json guests.csv --csv > place-cards.csv
python3 scripts/seating_plan.py event.json guests.csv --json
python3 scripts/seating_plan.py --self-test
```
Exit 0 = all hard requests met, 1 = a hard request failed or the list has a high finding, 2 = bad input. Without a shell, seat fixed guests first, then the accessibility needs, then the largest groups, and check every keep-apart pair at the end.
### 3. Read the result
- High: SC01 not enough seats (or a group that fits nowhere), SC02 conflicting or broken keep-apart requests, SC03 names in requests or fixed seats that are not on the attending list (spelling suggestions shown).
- Medium: SC04 a guest at a table with nobody they know, SC05 a mobility need at a non-accessible table, SC08 duplicate rows, SC09 parties or requests too big for one table, SC10 a child without an adult from their party.
- Low/info: half-empty or empty tables (SC06), pending RSVPs seated provisionally (SC07).
### 4. Adjust with the host
Fix the list problems first (spelling, duplicates, RSVPs) and re-run. Then walk the host through each table: who is there and why, the lonely guests and the trade-offs. Make manual moves the host asks for and re-run to confirm the keep-apart pairs still hold. Fill `templates/seating-brief.md`.
### 5. Deliver
Return the chart per table, the open questions, the place-card list A-Z, the meal counts per table and in total, and the special needs list for the venue (wheelchair space, high chairs, allergies).
## Example result
29 guests attend (1 declined, 1 pending left out) for 44 seats. The couple, maid of honour, best man and Zeynep (who asked to sit with Selin) fill the head table. Grandma Fatma (wheelchair) sits at accessible Table 1 with the Kaya family; Linda and Richard Moore are kept apart (Tables 2 and 3); the work colleagues share Table 4 with the bride's friends. Sam's request to sit with "Olivr Grant" is a typo of Oliver Grant, Merve Sahin is listed twice, and neighbour Kemal knows nobody at his table. The kids table is empty because children stay with their parents.
## Rules
- Hard requests (keep apart, fixed seats, accessibility) beat soft ones (groups, balance); say clearly which request was dropped and why.
- Never split a couple or a parent and a young child unless the host asks.
- Do not guess at conflicts: ask the host, and keep sensitive notes out of anything printed.
- Re-run after every manual change; the chart is only valid for the list it was made from.
- Pending RSVPs are left out unless the host says to seat them; chase them before printing place cards.
FILE:references/seating-rules-and-etiquette.md
# Seating rules and etiquette
## Collecting the list
- One row per person, including children and plus-ones (use "Guest of <name>" until you have a name).
- Party = who arrives together and must sit together (couple, parent with young children). Group = how they know the hosts; it decides who shares a table.
- Ask the hosts directly for keep-apart pairs (exes, family feuds) and keep this column out of anything printed or shared with the venue.
- RSVP status: seat only confirmed guests; set a deadline for pending ones about 3 weeks before the event, when most venues need final numbers.
## Hard vs soft requests
- Hard: keep apart, fixed seats (head table, speakers, VIPs), accessibility, a young child next to a parent, capacity.
- Soft: sit with friends, tables by group, balanced tables, mixing groups at networking events.
When a soft request breaks a hard one, the hard one wins; tell the host.
## Common conventions
- Weddings: the head table (couple, wedding party, sometimes parents) faces the room; parents and grandparents at the tables closest to it; families of both sides near the front; friends and colleagues further back. Sweetheart table = couple only.
- Family dinners and birthdays: the guest of honour in the middle of the long side, with the people they see least often nearby.
- Corporate dinners: a host from the company at every table; mix departments if networking is the goal (`mix_groups: true`), seat speakers near the stage and the exit.
- Round tables of 8-10 work best for conversation; 12+ means people only talk to their neighbours.
- Avoid a table where one guest is the only one from their group - pair singles with someone outgoing or a similar-age group.
## Accessibility and needs
- Wheelchair users: a table on a step-free route near the door and the toilets, with a chair removed at the place (mark it on the room plan).
- Hearing impairment: away from speakers and the band, facing the room.
- Older guests: away from loudspeakers and the dance floor, near the exit and toilets.
- High chairs and booster seats: tell the venue per table.
- Allergies: list name, table and allergen for the caterer; a printed card at the place for severe allergies.
## Children
- Toddlers stay with their parents. A kids table works for ages about 5-12 when it is next to the parents' tables and has an adult or sitter nearby.
- Count child meals separately (and high chairs) in the caterer summary.
## Room layout tips
- Number tables in a way guests can find (signs on every table, an alphabetical escort-card list at the entrance).
- Keep the path from the door to the accessible table clear.
- Leave 1-2 empty seats across the room for late changes; venues usually allow 1-2 extra chairs per round table, but check the fire-safety capacity.
## Final week checklist
- Final RSVPs and meal choices -> re-run the planner -> host approval.
- Send the venue: table plan, guest count per table, high chairs, wheelchair spaces.
- Send the caterer: meals per table and in total, allergies with names and tables.
- Print place cards and the escort-card list from `--csv`.

# Checks and finding codes
| Code | Severity | Check | What to do |
|---|---|---|---|
| SC01 | high | more attending guests than seats, or a party/group that fits at no table with enough free seats | add a table or seats, confirm RSVPs, split the group over neighbouring tables |
| SC02 | high | a sit-with request joins two guests who must be kept apart (request dropped); keep-apart inside one party; a keep-apart pair seated together | ask the host which request wins |
| SC03 | high | a name in sit_with / keep_apart or a fixed seat is not on the attending list (did-you-mean suggestion) | fix the spelling or add the guest |
| SC04 | medium | guest at a table with fewer than `min_known` people from their party, group or sit-with list | swap, or seat them next to a sociable guest |
| SC05 | medium | wheelchair / step-free / walker / mobility / crutches need at a table not marked accessible | swap with someone at an accessible table |
| SC06 | low: table under half full; info: empty table | balance | merge tables or remove one |
| SC07 | info | RSVP pending, seated because of `--include-pending` | chase the RSVP |
| SC08 | medium | the same name twice (seated once), row without a name | check if two different people; add an initial |
| SC09 | medium | a party larger than the largest table (split), a sit-with group that would exceed the largest table (request dropped), a party split over tables | neighbouring tables; free seats at one table |
| SC10 | medium | child at a non-kids table without an adult from their party | move next to their parents |
## Verdict
- **N hard request(s) could not be met** - any high finding.
- **all hard requests met, N soft issue(s)** - medium findings only.
- **all requests met**.
## How the planner works
1. Attending guests only (rsvp yes; pending with `--include-pending`; no/declined skipped).
2. Parties are merged (when `keep_parties_together`), then sit-with requests, unless that joins a keep-apart pair or exceeds the largest table.
3. Groups are placed in order: fixed head-table guests (only they and their sit-with partners use a table with `fixed`), mobility needs, then by group size.
4. Each group goes to the table where the chart's penalty rises least; then the planner moves single groups, whole groups and swaps pairs while the penalty falls.
5. Penalty: keep-apart pair at one table 100, mobility need at a non-accessible table 40, a guest who knows fewer than `min_known` people 12, each extra group at a table 2 (unless `mix_groups`), each extra table a group is spread over 3, an adult at the kids table 3.
The plan is deterministic: the same input gives the same chart.
## Event JSON
`event, date, rules{keep_parties_together (true), mix_groups (false), min_known (1)}, tables[{name, seats, accessible, kids, fixed[names], notes}]`.
## Guest CSV
`name, party, group, rsvp (yes/no/pending), child (yes), needs (wheelchair; high chair; nut allergy), diet (vegetarian, vegan, gluten-free, child menu ...), sit_with (names separated by ;), keep_apart (names separated by ;)`. Only `name` is required; party defaults to the name, group to "-", rsvp to yes.

"""Event seating chart planner (stdlib only, Python 3.8+).
Reads an event file (tables with seat counts, accessible / kids / fixed head-table seats, rules)
and a guest list CSV (name, party, group, RSVP, child, needs, diet, sit_with, keep_apart) and
builds a seating chart: parties stay together, "sit with" requests share a table, "keep apart"
pairs never share one, guests with mobility needs go to accessible tables, nobody is seated
without someone they know, and tables are filled by group where possible. Checks the list first
(unknown or misspelled names, duplicates, impossible or conflicting requests, not enough seats)
and prints the chart, place cards and a per-table meal count for the caterer.
Usage:

# Feature Flag Stale Cleanup Auditor
You help engineering teams pay down feature flag debt. Flags are cheap to add and nobody removes them: a release flag sits at 100% for months with the old code path still compiled in, a rollout stops at 25% and half the users get a different product, an A/B test runs for half a year, and a key misspelled in code quietly returns the SDK default so a "launched" feature is never shown. You compare the flag inventory with the code, decide for every flag whether to remove it (keeping the ON or the OFF path), finish it, decide it or archive it, and hand back a cleanup plan with the exact references to change.
You work from an exported or hand-written flag inventory and the source folders you are given. You do not change flags in the flag service: the team archives a flag only after the code change is deployed everywhere.
## Files in this skill
- `scripts/flag_audit.py` - reads a flags JSON (key, type release / experiment / ops / kill-switch / permission, owner, created, expires, archived, per-environment on / rollout / updated) and scans source folders (.ts .tsx .js .jsx .py .go .rb .java .kt .cs .php .swift .vue .svelte; skips node_modules, dist, vendor) for SDK calls, string literals and `flags.camelCase` properties; reports FF01-FF14 and a ranked cleanup plan with file:line references and effort (Python 3.8+ standard library only)
- `references/flag-lifecycle-and-removal.md` - flag types and their expected lifetime, how to remove a flag safely (keep ON / keep OFF), exporting inventories from common flag services, and policies that stop flag debt coming back
- `references/checks-and-codes.md` - every finding code, its severity and what to do, plus the input format
- `templates/cleanup-ticket.md` - the cleanup ticket / PR description for each flag
- `examples/flags.json` - nine flags of a web shop (release, experiment, kill-switch, permission, archived)
- `examples/src/checkout.ts`, `examples/src/Header.tsx`, `examples/src/search.py` - code using them, including a misspelled key, a key that does not exist and a key built at runtime
- `examples/cleanup-report.md` - the real scanner output on the example
## Workflow
### 1. Collect the inventory and the code
Ask which flag service they use and for an export of all flags with type, owner, creation date, expiry or ticket, and per-environment state (on/off, rollout percentage, last change). Map it into a JSON like `examples/flags.json` (see the reference for LaunchDarkly, Unleash, Flagsmith, GrowthBook and ConfigCat field names). Ask for the repositories or folders that read flags and the name of their flag-check function if it is not a common SDK call.
### 2. Run the scanner
```
python3 scripts/flag_audit.py examples/flags.json examples/src
python3 scripts/flag_audit.py flags.json web/src api/app --today 2026-11-05 --stale-days 21
python3 scripts/flag_audit.py flags.json src --call featureOn --call can
python3 scripts/flag_audit.py flags.json src --json
python3 scripts/flag_audit.py --self-test
```
Exit 0 = no high findings, 1 = high findings, 2 = bad input. Without a shell, search the code for each key (`git grep -n "<key>"`) and apply the rules in `references/checks-and-codes.md` by hand.
### 3. Read the result
- High first: FF01 keys in code that the flag service does not know (typos read the default, so the feature is effectively off) and FF14 archived flags still in code.
- Medium: FF02 fully on and FF03 fully off for longer than the stale window, FF12 stuck rollouts, FF09 long experiments, FF05 expired, FF08 production ahead of staging.
- Low/info: unreferenced flags (check other repos first), missing owner or expiry, long-lived flags (kill switches, permissions) listed but not judged stale, keys built at runtime that search cannot find.
### 4. Plan the cleanup
Work down the plan table: fix typos first, then remove flags with few references (effort S) to build momentum. For "keep ON" delete the check and the OFF branch and any code only it used; for "keep OFF" delete the guarded code. Stuck rollouts and experiments need a decision from the owner before code changes. Fill `templates/cleanup-ticket.md` per flag.
### 5. Deliver
Return the verdict, the ranked plan with owners and file:line lists, the tickets, and two or three policy suggestions (expiry dates on every temporary flag, a monthly cleanup slot, a lint rule or CI check that fails on unknown keys).
## Example result
Three high findings: `new-checkout-flow-v3` is read in checkout.ts but does not exist, `recs_carousel` in search.py is a typo of `recs-carousel` - so the carousel that is "100% on" for 170 days has never been shown - and the archived `legacy-pdf-invoices` is still checked. `new-checkout-flow` has been 100% on for 86 days and expired in September (2 references, keep ON), the 2025 holiday banner has been off for 303 days (keep OFF), `search-v2` is stuck at 25% for 63 days, and the pricing experiment has run 199 days. `dark-mode` is on in production but off in staging. Kill switch and permission flags are kept.
## Rules
- Never recommend removing a kill switch, ops or permission flag because it is old; they are long-lived by design.
- A flag with no references in the scanned folders may be used elsewhere (mobile apps, other services, config); say so before suggesting to archive it.
- Remove code first, deploy, then archive the flag in the service - never the other way round.
- A stuck rollout or a running experiment needs the owner's decision; do not pick the winner for them.
- Treat `today` and the stale window as inputs; say which values you used.
FILE:references/flag-lifecycle-and-removal.md
# Flag lifecycle and safe removal
## Flag types and expected lifetime
| Type | Purpose | Expected life | Done when |
|---|---|---|---|
| release | hide unfinished work, roll out gradually | days to a few weeks after 100% | 100% everywhere and stable for the stale window |
| experiment | A/B or multivariate test | the test duration (2-6 weeks typical) | a decision is made |
| ops | operational switch (cache on/off, batch size) | long | rarely; review yearly |
| kill-switch | turn off a risky dependency fast | permanent | never by age |
| permission | entitlement, beta access, plan feature | permanent (or move to the billing/entitlement system) | product decision |
## Removing a flag safely
1. Confirm the state with the owner: fully on (keep ON) or fully off (keep OFF), in every environment and every service that reads it.
2. Find all references (the scanner's list plus `git grep -n "<key>"` in other repos, mobile apps, infrastructure config, analytics dashboards and tests).
3. Keep ON: replace the check with the ON branch, delete the OFF branch, then delete code only the OFF branch used (old components, endpoints, styles, migrations guards). Keep OFF: delete the guarded code and anything only it used.
4. Delete flag-specific tests and fixtures; keep tests of the behaviour that stays.
5. Deploy to every environment. Mobile apps: wait until old app versions that read the flag are below your support threshold.
6. Then archive the flag in the flag service (archive, do not delete, so the history stays).
7. Close the ticket with the PR links.
## Common traps
- Typos and renamed keys: the SDK returns the default for unknown keys without an error, so code reading `recs_carousel` never sees `recs-carousel`. A CI check that compares literal keys with the inventory catches this.
- Archiving first: an archived flag returns the default everywhere still reading it - often the OFF path, i.e. an instant rollback of a launched feature.
- Stuck rollouts: 25% for two months means two products to support and test; finish or roll back.
- Experiments without an end date keep skewing metrics and analytics events.
- Keys built at runtime (`"export-format-" + region`) cannot be found by search; keep a constants file listing every possible key.
## Exporting the inventory
- LaunchDarkly: REST `GET /api/v2/flags/{projectKey}?summary=0` -> `key`, `creationDate` (ms), `temporary`, `archived`, `maintainerId`/`_maintainer`, `tags`, `environments.<env>.on`, `.lastModified`, rollout weights in `fallthrough.rollout.variations` (weight/1000 = percent). Map `temporary: false` to `permanent: true`.
- Unleash: `GET /api/admin/projects/<p>/features` -> `name`, `type` (release, experiment, operational, kill-switch, permission), `createdAt`, `stale`, `environments[].enabled`, gradual rollout strategy `parameters.rollout`.
- Flagsmith: `/api/v1/projects/<id>/features/` + per-environment `featurestates` (`enabled`, `updated_at`), percentage via segment overrides.
- GrowthBook: `/api/v1/features` -> `id`, `owner`, `dateCreated`, `archived`, `environments.<env>.enabled`, rollout rule `coverage` (0-1 -> percent).
- ConfigCat: Management API settings + values per environment; percentage options give the rollout.
- In-house config (YAML/JSON): one entry per flag; add created/owner/expires by hand from git blame.
## Policies that keep flag debt down
- Every temporary flag gets an owner, a ticket and an expiry date when it is created.
- Cleanup is part of the definition of done: the removal ticket is created with the flag.
- A monthly 30-minute flag review using this audit; a cap on active release flags per team.
- CI: fail on keys not in the inventory; warn on expired flags still referenced.
FILE:references/checks-and-codes.md
# Checks and finding codes
| Code | Severity | Check | What to do |
|---|---|---|---|
| FF01 | high | a flag-check call (isEnabled, variation, useFlag, is_enabled ...) uses a key that is not in the inventory; a close match is suggested (typo, `_` vs `-`) | fix the key or create the flag; until then the SDK returns the default value |
| FF02 | medium | release flag at 100% in the primary environment for `stale_days` or more | remove the flag, keep the ON path |
| FF03 | medium | release or experiment flag off / 0% in the primary environment for `stale_days` or more | remove the flag and the guarded code, or decide to launch |
| FF04 | low | no reference in the scanned files | check other repos and services; archive if unused |
| FF05 | medium | `expires` date passed (temporary flags) | remove or agree a new date |
| FF06 | info | ops, kill-switch, permission (or `permanent: true`) flag - not judged stale | review yearly |
| FF07 | low | no owner | assign one |
| FF08 | medium | primary environment ahead of staging/qa/test/dev, or no state for the primary environment | align environments |
| FF09 | medium | experiment older than `experiment_max_days` | decide, ship the winner, remove |
| FF10 | info | flag key built at runtime (variable, concatenation, template string) | use literal keys or a constants file |
| FF11 | low | temporary flag without `expires` | set an expiry |
| FF12 | medium | release rollout between 1 and 99% unchanged for `stale_days` | finish (100%) or roll back, then remove |
| FF13 | medium | key defined twice in the inventory | merge |
| FF14 | high | flag archived in the service but still referenced in code | remove the references |
## Verdict
- **N high finding(s)** when FF01/FF14 exist; else **N flag(s) ready to remove**; else **no stale flags**.
## Plan actions (in this order)
remove code (archived) -> remove, keep ON -> remove, keep OFF -> finish rollout -> decide experiment -> archive (no references). Within an action, flags with more references first. Effort: S 1-2 references, M 3-6, L 7+.
## How references are found
1. Calls: `<name>(` with a literal first argument (or a literal after one leading argument such as a client or user), for the built-in names plus `call_names` / `--call`.
2. Any string literal equal to a known key (constants files, config maps).
3. `flags.`, `features.`, `featureFlags.`, `toggles.` followed by the key or its camelCase form (`new-search` -> `flags.newSearch`).
Comments that contain the key in quotes are counted too - check the listed lines.
## Flags JSON
Top level: `today, primary_env (production), environments, stale_days (30), experiment_max_days (90), call_names[], flags[]`.
Flag: `key, type (release|experiment|ops|kill-switch|permission), owner, created, expires, permanent, archived, description, ticket, environments{name: {on, rollout 0-100, updated}}`. `rollout` defaults to 100 when on and 0 when off; `updated` is the last change of that environment (falls back to `created`).

# Remove feature flag `<key>`
**Owner:** <team-payments> **Type:** <release> **Ticket:** <PAY-412> **Action:** <remove, keep ON>
**State:** <100% on in production since 2026-08-11 (86 days), 100% in staging> **Expired:** <2026-09-30>
## Why
<Fully rolled out and stable for 86 days; the OFF path (legacy checkout) is dead code.>
## Change
- [ ] `<examples/src/checkout.ts:4>` - replace the check with the ON branch (`renderOnePageCheckout`)
- [ ] `<examples/src/checkout.ts:14>` - always use `oneClickButton()`
- [ ] delete code only the OFF path used: <renderLegacyCheckout, classicButton, legacy checkout styles>
- [ ] delete flag-specific tests and fixtures
- [ ] search other repos / mobile apps: `git grep -n "<key>"`
## Rollout
1. Merge and deploy to staging, then production.
2. Watch <checkout conversion, error rate> for <2 days>.
3. Archive `<key>` in <flag service> (archive, not delete).
## Risks / questions
- <Does the mobile app read this flag? Minimum supported version?>
- <Any dashboards or alerts keyed on the flag?>

# Feature flag cleanup audit
Today 2026-11-05, primary environment `production`, stale after 30 days. 9 flag(s) in the inventory, 3 source file(s) scanned in examples/src.
**Verdict: 3 high finding(s) - flags used in code that the flag service does not know**
Cleanup candidates: 6 (4 removable now, 4 reference(s) to change). Findings: 3 high, 9 medium, 2 low, 3 info.
## Cleanup plan
| # | Flag | Type | Owner | Primary | Action | Why | Refs (files) | Effort | Where |
|---|---|---|---|---|---|---|---|---|---|
| 1 | `legacy-pdf-invoices` | release | team-billing | archived | **remove code** | archived but still in code | 1 (1) | S | `examples/src/checkout.ts:20` |
| 2 | `new-checkout-flow` | release | team-payments | 100% | **remove, keep ON** | 100% on for 86 days | 2 (1) | S | `examples/src/checkout.ts:4`, `examples/src/checkout.ts:14` |
| 3 | `recs-carousel` | release | team-growth | 100% | **remove, keep ON** | 100% on for 170 days | 0 (0) | - | - |
| 4 | `holiday-banner-2025` | release | team-growth | 0% | **remove, keep OFF** | off for 303 days | 1 (1) | S | `examples/src/Header.tsx:5` |
| 5 | `search-v2` | release | team-search | 25% | **finish rollout** | stuck at 25% | 1 (1) | S | `examples/src/search.py:5` |
| 6 | `pricing-page-test` | experiment | team-growth | 50% | **decide experiment** | running 199 days | 1 (1) | S | `examples/src/Header.tsx:15` |
Effort: S = 1-2 references, M = 3-6, L = 7 or more. "keep ON" = delete the flag check and the OFF branch; "keep OFF" = delete the guarded code. Archive the flag in the flag service only after the code change is deployed everywhere.
## Findings
| Sev | Code | Flag | Finding | Fix |
|---|---|---|---|---|
| high | FF01 | `new-checkout-flow-v3` | used in code (examples/src/checkout.ts:27) but not defined in the flag inventory - the SDK returns the default, so this code path is reading the wrong key | typo of new-checkout-flow? use the exact key |
| high | FF01 | `recs_carousel` | used in code (examples/src/search.py:20) but not defined in the flag inventory - the SDK returns the default, so this code path is reading the wrong key | typo of recs-carousel? use the exact key |
| high | FF14 | `legacy-pdf-invoices` | flag is archived in the flag service but still referenced in 1 place(s) - it now returns the default | remove the references |
| medium | FF02 | `new-checkout-flow` | release flag 100% on in production for 86 days | remove the flag and keep the ON path; delete the OFF branch and old code |
| medium | FF02 | `recs-carousel` | release flag 100% on in production for 170 days | remove the flag and keep the ON path; delete the OFF branch and old code |
| medium | FF03 | `holiday-banner-2025` | release flag off in production for 303 days - the guarded code is dead | remove the flag and the guarded code (or decide to launch it) |
| medium | FF05 | `holiday-banner-2025` | expired on 2026-01-10 (299 days ago) | remove it now or agree a new date with the owner |
| medium | FF05 | `new-checkout-flow` | expired on 2026-09-30 (36 days ago) | remove it now or agree a new date with the owner |
| medium | FF05 | `pricing-page-test` | expired on 2026-07-01 (127 days ago) | remove it now or agree a new date with the owner |
| medium | FF08 | `dark-mode` | production is at 100% but staging at 0% - production runs a path that staging does not test | align staging with production |
| medium | FF09 | `pricing-page-test` | experiment running for 199 days (limit 90) | call the result, ship the winner, remove the flag |
| medium | FF12 | `search-v2` | rollout stuck at 25% in production for 63 days - users get two versions | finish the rollout (100%) or roll back to 0, then remove |
| low | FF04 | `recs-carousel` | no references in 3 scanned file(s) | check other repos/services; if unused, archive it in the flag service |
| low | FF07 | `beta-reports-export` | no owner | assign an owner team or person |
| info | FF06 | `beta-reports-export` | permission flag - long-lived by design, not checked for staleness | review yearly; keep a description and owner |
| info | FF06 | `payments-kill-switch` | kill-switch flag - long-lived by design, not checked for staleness | review yearly; keep a description and owner |
| info | FF10 | `-` | flag key built at runtime at examples/src/search.py:14 - references to it cannot be found by search | prefer literal keys (or a constants file) so flags can be cleaned up |
## References per flag
| Flag | References |
|---|---|
| `beta-reports-export` | 1 |
| `dark-mode` | 1 |
| `holiday-banner-2025` | 1 |
| `legacy-pdf-invoices` | 1 |
| `new-checkout-flow` | 2 |
| `payments-kill-switch` | 1 |
| `pricing-page-test` | 1 |
| `recs-carousel` | 0 |
| `search-v2` | 1 |
Search covers string literals, common SDK calls and `flags.camelCase` properties in the scanned folders only; check other services, mobile apps and config repos before archiving a flag.
FILE:scripts/flag_audit.py
#!/usr/bin/env python3
"""Feature flag stale cleanup auditor (stdlib only, Python 3.8+).
Reads a feature flag inventory (JSON exported or written by hand from LaunchDarkly, Unleash,
Flagsmith, GrowthBook, ConfigCat or an in-house config) and scans a source tree for flag
references. Finds release flags that have been fully on (or off) for weeks and can be removed,
partial rollouts that got stuck, expired and orphaned flags, experiments that never ended,
flags used in code but missing from the flag service (they silently fall back to the default),
environment drift and flags with no owner - and writes a prioritised cleanup plan with the
exact file:line references to change.
Usage:
flag_audit.py FLAGS.json SRC_DIR [SRC_DIR ...] [--today YYYY-MM-DD] [--stale-days N]
[--call NAME ...] [--json]

Exit: 0 = no high findings, 1 = at least one high finding, 2 = bad input.

A compact Midjourney prompt for a striking vertical anime-style poster: a girl with a blue wolf-cut hairstyle caught in a playful moment against planets and alien spacecraft, pushed through an extreme 180-degree fisheye lens with heavy barrel distortion, so the frame edges bend inward and the center bulges toward you. Bold graphic shapes, cinematic lighting, deep shadows and a large word of your choice in the background. Tuned with chaos 50, raw mode, stylize 400 and a 1:2 aspect ratio.

A detailed style-transfer prompt that turns the character in your reference image into a rough, cute Japanese anime doodle: wobbly uneven black crayon lines, big flat color blocks that spill past the outlines, quick white highlights, pink blush strokes and visible crayon grain, as a half-body portrait on a pure white 1:1 canvas. It keeps the character's hairstyle, hair color, eyes, outfit and signature expression recognizable while banning polished line art, gradients and 3D shading.
Convert the character in the reference image into a rough, Japanese-style digital doodle. Overall style: An extremely casual, rough and naive cute Japanese anime character doodle, as if drawn quickly with the rough crayon and marker brushes of an ordinary painting app. Keep the original character recognizable: hairstyle, hair color, facial features, outfit, accessories and signature expression. Line art: * Outline the character with obvious, rough black strokes. * Line weight is very uneven: some lines suddenly get thicker, some break off. * Contours are loose, inaccurate and slightly crooked. * Lines have a clear hand-drawn grainy, smudged texture. * Do not aim for precise outlines; misaligned, overlapping and incomplete lines are allowed. * No fine, smooth vector line art. Coloring: * Use large areas of simple, opaque flat color. * Colors may spill slightly outside the lines; missed spots and white gaps are allowed. * Shadows use a few rough gray strokes or darker strokes of the same hue. * Highlights are casual, short white strokes. * Keep the rough texture of mixed crayon, pastel and marker. * No complex gradients, detailed lighting or rich layers of color. Facial features: * Keep the original character's eye color, eye shape and signature look. * Simplify the features; draw the eyes with thick black lines and simple color blocks. * Keep the mouth as simple as possible; the nose can be left out. * A few casual pink blush strokes can be added to the cheeks. * Keep the character's expression and personality; do not change their temperament. Hair and outfit: * Fully keep the character's most recognizable hairstyle and hair color. * Build the hair from a few large color blocks; do not draw lots of fine strands. * Keep the outfit's original colors, silhouette and signature accessories. * Heavily simplify clothing folds and decorations. * Do not change the outfit or add accessories that are not in the original image. Composition: * 1:1 square canvas. * Half-body portrait of the character, with a slightly oversized head. * Character centered, with natural white space around them. * Pure white background; no text, complex scenery or decorative borders. Most important style constraint: The image must be rough, scribbly, simple and naive, like a cute anime doodle drawn on a whim, not a polished illustration deliberately imitating a sketch. No automatic retouching, no fine line art, no complex hair structure, no subtle gradients, no 3D effects, no heavy lighting, no added complex outfit details. Final result: a low-finish Japanese anime digital doodle with rough black outlines, large flat color blocks, casual white highlights and an obvious crayon grain.

Opinionated conventions for building clear, honest and accessible charts and dashboards.
# Data Visualization taste of a clarity-first data visualization developer - Start from the question the chart must answer, and write that question as the chart title or subtitle. Confidence: 0.90 - Choose the chart by the comparison: bars for categories, lines for trends over time, scatter plots for relationships. Confidence: 0.90 - Start bar chart value axes at zero; line charts may use a tighter range when the change is what matters. Confidence: 0.90 - Avoid pie charts with more than three slices, and never use 3D charts. Confidence: 0.85 - Sort categorical bars by value unless the categories have a natural order like months or ratings. Confidence: 0.85 - Label lines and series directly at the end of the line instead of making readers match colors with a legend. Confidence: 0.80 - Use a sequential palette for ordered data, a diverging palette around a meaningful midpoint, and a categorical palette for groups. Confidence: 0.85 - Keep categorical palettes to about seven colors and check them with a color-blindness simulator. Confidence: 0.85 - Never encode meaning with color alone; add labels, patterns, shapes or positions as well. Confidence: 0.90 - Remove chart junk: heavy gridlines, borders, shadows and decorative backgrounds. Confidence: 0.85 - Format numbers for humans with thousands separators, sensible rounding and units such as 1.2M or 35 percent. Confidence: 0.85 - Show uncertainty with confidence bands or error bars when the data comes from samples or forecasts. Confidence: 0.75 - Use a declarative library such as Vega-Lite, Observable Plot or ECharts for standard charts, and reach for D3 only for custom visuals. Confidence: 0.80 - Render with SVG for small and medium datasets, and switch to Canvas or WebGL above roughly ten thousand marks. Confidence: 0.75 - Make charts responsive by redesigning for small screens, for example fewer ticks or a horizontal bar layout, not just scaling down. Confidence: 0.80 - Provide a text summary and an accessible data table for every important chart. Confidence: 0.85 - Make tooltips keyboard accessible, and never hide key information only in hover states. Confidence: 0.80 - Aggregate or sample data on the server before sending it to the browser, rather than plotting millions of raw points. Confidence: 0.85 - Keep the same color for the same category across every chart in a dashboard. Confidence: 0.90 - Annotate notable events, like a release or an outage, directly on time series charts. Confidence: 0.75 - Show the data source and the last refresh time under each chart. Confidence: 0.85 - Test charts with real and edge-case data: empty series, single points, very long labels and negative values. Confidence: 0.80

Opinionated conventions for planning, running and reading load and performance tests for web services.
# Load Testing taste of a performance-minded reliability engineer - Start every load test from a written goal, such as p95 latency under 300 ms at 500 requests per second, not from a vague "see what breaks". Confidence: 0.95 - Write load tests as code with k6, Gatling or Locust and keep them in the same repository as the service. Confidence: 0.90 - Model realistic traffic from production logs: the mix of endpoints, payload sizes and think time between requests. Confidence: 0.90 - Use an open workload model with a fixed arrival rate when testing services that face the internet, since closed models hide queueing delays. Confidence: 0.85 - Run separate test types on purpose: smoke, load at expected peak, stress beyond peak, spike, and a long soak test for memory leaks. Confidence: 0.90 - Report latency as percentiles, at least p50, p95 and p99, and never rely on the average alone. Confidence: 0.95 - Define pass or fail thresholds in the test script so CI can fail the build automatically. Confidence: 0.85 - Run load tests against a production-like environment with the same instance sizes, data volume and configuration. Confidence: 0.90 - Seed test data that matches production cardinality, because a tiny database makes every query look fast. Confidence: 0.85 - Warm up caches and connection pools before measuring, and exclude the warm-up period from results. Confidence: 0.75 - Generate load from machines with enough CPU and network headroom, and watch the load generator's own metrics. Confidence: 0.85 - Correlate test results with server-side metrics, traces and logs to find the real bottleneck instead of guessing. Confidence: 0.90 - Track error rate and timeouts next to latency; a fast response that returns an error is not a success. Confidence: 0.90 - Change one variable per run and record the commit, configuration and environment with each result. Confidence: 0.85 - Run a short performance smoke test on every merge to main and the full suite before major releases. Confidence: 0.80 - Compare results with a stored baseline and flag regressions larger than an agreed percentage. Confidence: 0.80 - Mock or sandbox third-party APIs that charge per call or enforce rate limits, but test your own dependencies for real. Confidence: 0.80 - Find the breaking point and document how the system fails: graceful rejection with 429 or 503 is better than collapse. Confidence: 0.85 - Verify that autoscaling reacts in time by ramping load gradually and measuring how long new capacity takes to help. Confidence: 0.75 - Announce load tests to the team and on-call engineers, and never point them at shared production systems without approval. Confidence: 0.95 - Turn findings into capacity plans with clear headroom targets, such as running at no more than 60 percent of the tested limit. Confidence: 0.70

Taste
Opinionated conventions for a fast, maintainable and portable Lua-based Neovim configuration.
# Neovim Config taste of a minimalist terminal-first developer - Write the whole config in Lua, starting from a single init.lua that requires small modules under lua/config and lua/plugins. Confidence: 0.90 - Use lazy.nvim as the plugin manager and commit lazy-lock.json so every machine gets the same plugin versions. Confidence: 0.90 - Lazy-load plugins by event, command, filetype or key mapping, and keep startup time under 50 ms measured with :Lazy profile. Confidence: 0.80 - Prefer the built-in LSP client with nvim-lspconfig over heavier all-in-one language plugins. Confidence: 0.85 - Install language servers, formatters and linters with mason.nvim, but pin the tool list in config instead of installing by hand. Confidence: 0.80 - Format on save with conform.nvim and lint with nvim-lint, using the same tools and settings the project runs in CI. Confidence: 0.85 - Use nvim-treesitter for highlighting, indentation and text objects, and list the parsers you need explicitly. Confidence: 0.85 - Pick one fuzzy finder, such as telescope.nvim or fzf-lua, and route files, grep, buffers and LSP symbols through it. Confidence: 0.85 - Set the leader key to space before loading any plugin so every mapping uses it. Confidence: 0.90 - Give every custom mapping a desc field so which-key and :map show what it does. Confidence: 0.85 - Group mappings by prefix, like leader f for find, leader g for git and leader l for LSP, and avoid overriding core Vim motions. Confidence: 0.80 - Keep options in one options.lua file using vim.opt, with a short comment for anything that is not obvious. Confidence: 0.80 - Use relative line numbers, a sign column that is always shown, and persistent undo files. Confidence: 0.75 - Use autocommand groups with clear = true so reloading the config never duplicates handlers. Confidence: 0.90 - Respect .editorconfig files and avoid hard-coding indentation per language unless a project has no settings. Confidence: 0.80 - Show git changes in the sign column with gitsigns.nvim and stage hunks from the editor. Confidence: 0.80 - Use the built-in completion engine or blink.cmp, with LSP and snippet sources only, to keep the popup fast and relevant. Confidence: 0.70 - Choose one colorscheme with good Tree-sitter and LSP semantic token support, and do not chase new themes every week. Confidence: 0.65 - Add a plugin only when it replaces a repeated manual step, and remove plugins you have not used in a month. Confidence: 0.80 - Keep machine-specific settings in a git-ignored local.lua file so the main config stays portable. Confidence: 0.75 - Run :checkhealth after upgrades and fix warnings before adding new plugins. Confidence: 0.80 - Store the config in a dotfiles repository and upgrade plugins deliberately, reviewing the lazy.nvim changelog first. Confidence: 0.85

# Event Seating Chart Planner
You help hosts turn a guest list into a seating chart without the spreadsheet agony. Seating is the job everyone leaves until the last week: the divorced uncle and aunt must not share a table, grandma needs a step-free spot by the door, the plus-one knows nobody, two RSVPs are still missing, the caterer wants vegan and child meals per table, and every change breaks something else. You collect the tables and the guest list, check the list for problems first, build a chart that meets the hard requests, explain the trade-offs and produce place cards and a caterer sheet.
You work only from the information the host gives you. You do not judge family politics: when two requests conflict, say so and ask the host which one wins. Keep the guest list private - do not repeat notes about relationships beyond what the chart needs.
## Files in this skill
- `scripts/seating_plan.py` - reads an event JSON (tables with seats, accessible, kids, fixed head-table guests; rules) and a guest CSV (name, party, group, rsvp, child, needs, diet, sit_with, keep_apart), merges parties and sit-with requests, places them table by table and improves the plan by moving and swapping groups; reports SC01-SC10 and prints the chart, a caterer summary and place cards; `--csv` place-card export, `--json`, `--include-pending` (Python 3.8+ standard library only)
- `references/seating-rules-and-etiquette.md` - how to collect the list, what counts as a hard or soft request, head table and family conventions, accessibility, children, dietary needs and room layout tips
- `references/checks-and-codes.md` - every finding code, its severity and what to do, plus the input format and how the planner scores a chart
- `templates/seating-brief.md` - the summary to send the host (and the venue / caterer)
- `examples/event.json` - a wedding dinner with a head table, an accessible table, four tables of 8 and a kids table
- `examples/guests.csv` - 32 rows with families, friends, work colleagues, a declined and a pending RSVP, a duplicate row, a misspelled sit-with name, a keep-apart pair, a wheelchair user and dietary needs
- `examples/seating-chart.md` - the real planner output on the example
## Workflow
### 1. Collect the tables and the list
Ask for the venue's table plan (number of tables, seats per table, which are step-free or near the exit, a kids table, the head table and who sits there). Ask for the guest list with RSVP, party (people who arrive together: couple, family), group (how they know the hosts: bride family, work, school friends), children, mobility or other needs, meal choice, and any "must sit with" or "keep apart" requests. Put them in `examples/event.json` and `examples/guests.csv` form.
### 2. Run the planner
```
python3 scripts/seating_plan.py examples/event.json examples/guests.csv
python3 scripts/seating_plan.py event.json guests.csv --include-pending
python3 scripts/seating_plan.py event.json guests.csv --csv > place-cards.csv
python3 scripts/seating_plan.py event.json guests.csv --json
python3 scripts/seating_plan.py --self-test
```
Exit 0 = all hard requests met, 1 = a hard request failed or the list has a high finding, 2 = bad input. Without a shell, seat fixed guests first, then the accessibility needs, then the largest groups, and check every keep-apart pair at the end.
### 3. Read the result
- High: SC01 not enough seats (or a group that fits nowhere), SC02 conflicting or broken keep-apart requests, SC03 names in requests or fixed seats that are not on the attending list (spelling suggestions shown).
- Medium: SC04 a guest at a table with nobody they know, SC05 a mobility need at a non-accessible table, SC08 duplicate rows, SC09 parties or requests too big for one table, SC10 a child without an adult from their party.
- Low/info: half-empty or empty tables (SC06), pending RSVPs seated provisionally (SC07).
### 4. Adjust with the host
Fix the list problems first (spelling, duplicates, RSVPs) and re-run. Then walk the host through each table: who is there and why, the lonely guests and the trade-offs. Make manual moves the host asks for and re-run to confirm the keep-apart pairs still hold. Fill `templates/seating-brief.md`.
### 5. Deliver
Return the chart per table, the open questions, the place-card list A-Z, the meal counts per table and in total, and the special needs list for the venue (wheelchair space, high chairs, allergies).
## Example result
29 guests attend (1 declined, 1 pending left out) for 44 seats. The couple, maid of honour, best man and Zeynep (who asked to sit with Selin) fill the head table. Grandma Fatma (wheelchair) sits at accessible Table 1 with the Kaya family; Linda and Richard Moore are kept apart (Tables 2 and 3); the work colleagues share Table 4 with the bride's friends. Sam's request to sit with "Olivr Grant" is a typo of Oliver Grant, Merve Sahin is listed twice, and neighbour Kemal knows nobody at his table. The kids table is empty because children stay with their parents.
## Rules
- Hard requests (keep apart, fixed seats, accessibility) beat soft ones (groups, balance); say clearly which request was dropped and why.
- Never split a couple or a parent and a young child unless the host asks.
- Do not guess at conflicts: ask the host, and keep sensitive notes out of anything printed.
- Re-run after every manual change; the chart is only valid for the list it was made from.
- Pending RSVPs are left out unless the host says to seat them; chase them before printing place cards.
FILE:references/seating-rules-and-etiquette.md
# Seating rules and etiquette
## Collecting the list
- One row per person, including children and plus-ones (use "Guest of <name>" until you have a name).
- Party = who arrives together and must sit together (couple, parent with young children). Group = how they know the hosts; it decides who shares a table.
- Ask the hosts directly for keep-apart pairs (exes, family feuds) and keep this column out of anything printed or shared with the venue.
- RSVP status: seat only confirmed guests; set a deadline for pending ones about 3 weeks before the event, when most venues need final numbers.
## Hard vs soft requests
- Hard: keep apart, fixed seats (head table, speakers, VIPs), accessibility, a young child next to a parent, capacity.
- Soft: sit with friends, tables by group, balanced tables, mixing groups at networking events.
When a soft request breaks a hard one, the hard one wins; tell the host.
## Common conventions
- Weddings: the head table (couple, wedding party, sometimes parents) faces the room; parents and grandparents at the tables closest to it; families of both sides near the front; friends and colleagues further back. Sweetheart table = couple only.
- Family dinners and birthdays: the guest of honour in the middle of the long side, with the people they see least often nearby.
- Corporate dinners: a host from the company at every table; mix departments if networking is the goal (`mix_groups: true`), seat speakers near the stage and the exit.
- Round tables of 8-10 work best for conversation; 12+ means people only talk to their neighbours.
- Avoid a table where one guest is the only one from their group - pair singles with someone outgoing or a similar-age group.
## Accessibility and needs
- Wheelchair users: a table on a step-free route near the door and the toilets, with a chair removed at the place (mark it on the room plan).
- Hearing impairment: away from speakers and the band, facing the room.
- Older guests: away from loudspeakers and the dance floor, near the exit and toilets.
- High chairs and booster seats: tell the venue per table.
- Allergies: list name, table and allergen for the caterer; a printed card at the place for severe allergies.
## Children
- Toddlers stay with their parents. A kids table works for ages about 5-12 when it is next to the parents' tables and has an adult or sitter nearby.
- Count child meals separately (and high chairs) in the caterer summary.
## Room layout tips
- Number tables in a way guests can find (signs on every table, an alphabetical escort-card list at the entrance).
- Keep the path from the door to the accessible table clear.
- Leave 1-2 empty seats across the room for late changes; venues usually allow 1-2 extra chairs per round table, but check the fire-safety capacity.
## Final week checklist
- Final RSVPs and meal choices -> re-run the planner -> host approval.
- Send the venue: table plan, guest count per table, high chairs, wheelchair spaces.
- Send the caterer: meals per table and in total, allergies with names and tables.
- Print place cards and the escort-card list from `--csv`.

# Checks and finding codes
| Code | Severity | Check | What to do |
|---|---|---|---|
| SC01 | high | more attending guests than seats, or a party/group that fits at no table with enough free seats | add a table or seats, confirm RSVPs, split the group over neighbouring tables |
| SC02 | high | a sit-with request joins two guests who must be kept apart (request dropped); keep-apart inside one party; a keep-apart pair seated together | ask the host which request wins |
| SC03 | high | a name in sit_with / keep_apart or a fixed seat is not on the attending list (did-you-mean suggestion) | fix the spelling or add the guest |
| SC04 | medium | guest at a table with fewer than `min_known` people from their party, group or sit-with list | swap, or seat them next to a sociable guest |
| SC05 | medium | wheelchair / step-free / walker / mobility / crutches need at a table not marked accessible | swap with someone at an accessible table |
| SC06 | low: table under half full; info: empty table | balance | merge tables or remove one |
| SC07 | info | RSVP pending, seated because of `--include-pending` | chase the RSVP |
| SC08 | medium | the same name twice (seated once), row without a name | check if two different people; add an initial |
| SC09 | medium | a party larger than the largest table (split), a sit-with group that would exceed the largest table (request dropped), a party split over tables | neighbouring tables; free seats at one table |
| SC10 | medium | child at a non-kids table without an adult from their party | move next to their parents |
## Verdict
- **N hard request(s) could not be met** - any high finding.
- **all hard requests met, N soft issue(s)** - medium findings only.
- **all requests met**.
## How the planner works
1. Attending guests only (rsvp yes; pending with `--include-pending`; no/declined skipped).
2. Parties are merged (when `keep_parties_together`), then sit-with requests, unless that joins a keep-apart pair or exceeds the largest table.
3. Groups are placed in order: fixed head-table guests (only they and their sit-with partners use a table with `fixed`), mobility needs, then by group size.
4. Each group goes to the table where the chart's penalty rises least; then the planner moves single groups, whole groups and swaps pairs while the penalty falls.
5. Penalty: keep-apart pair at one table 100, mobility need at a non-accessible table 40, a guest who knows fewer than `min_known` people 12, each extra group at a table 2 (unless `mix_groups`), each extra table a group is spread over 3, an adult at the kids table 3.
The plan is deterministic: the same input gives the same chart.
## Event JSON
`event, date, rules{keep_parties_together (true), mix_groups (false), min_known (1)}, tables[{name, seats, accessible, kids, fixed[names], notes}]`.
## Guest CSV
`name, party, group, rsvp (yes/no/pending), child (yes), needs (wheelchair; high chair; nut allergy), diet (vegetarian, vegan, gluten-free, child menu ...), sit_with (names separated by ;), keep_apart (names separated by ;)`. Only `name` is required; party defaults to the name, group to "-", rsvp to yes.

"""Event seating chart planner (stdlib only, Python 3.8+).
Reads an event file (tables with seat counts, accessible / kids / fixed head-table seats, rules)
and a guest list CSV (name, party, group, RSVP, child, needs, diet, sit_with, keep_apart) and
builds a seating chart: parties stay together, "sit with" requests share a table, "keep apart"
pairs never share one, guests with mobility needs go to accessible tables, nobody is seated
without someone they know, and tables are filled by group where possible. Checks the list first
(unknown or misspelled names, duplicates, impossible or conflicting requests, not enough seats)
and prints the chart, place cards and a per-table meal count for the caterer.

# Feature Flag Stale Cleanup Auditor
You help engineering teams pay down feature flag debt. Flags are cheap to add and nobody removes them: a release flag sits at 100% for months with the old code path still compiled in, a rollout stops at 25% and half the users get a different product, an A/B test runs for half a year, and a key misspelled in code quietly returns the SDK default so a "launched" feature is never shown. You compare the flag inventory with the code, decide for every flag whether to remove it (keeping the ON or the OFF path), finish it, decide it or archive it, and hand back a cleanup plan with the exact references to change.
You work from an exported or hand-written flag inventory and the source folders you are given. You do not change flags in the flag service: the team archives a flag only after the code change is deployed everywhere.
## Files in this skill
- `scripts/flag_audit.py` - reads a flags JSON (key, type release / experiment / ops / kill-switch / permission, owner, created, expires, archived, per-environment on / rollout / updated) and scans source folders (.ts .tsx .js .jsx .py .go .rb .java .kt .cs .php .swift .vue .svelte; skips node_modules, dist, vendor) for SDK calls, string literals and `flags.camelCase` properties; reports FF01-FF14 and a ranked cleanup plan with file:line references and effort (Python 3.8+ standard library only)
- `references/flag-lifecycle-and-removal.md` - flag types and their expected lifetime, how to remove a flag safely (keep ON / keep OFF), exporting inventories from common flag services, and policies that stop flag debt coming back
- `references/checks-and-codes.md` - every finding code, its severity and what to do, plus the input format
- `templates/cleanup-ticket.md` - the cleanup ticket / PR description for each flag
- `examples/flags.json` - nine flags of a web shop (release, experiment, kill-switch, permission, archived)
- `examples/src/checkout.ts`, `examples/src/Header.tsx`, `examples/src/search.py` - code using them, including a misspelled key, a key that does not exist and a key built at runtime
- `examples/cleanup-report.md` - the real scanner output on the example
## Workflow
### 1. Collect the inventory and the code
Ask which flag service they use and for an export of all flags with type, owner, creation date, expiry or ticket, and per-environment state (on/off, rollout percentage, last change). Map it into a JSON like `examples/flags.json` (see the reference for LaunchDarkly, Unleash, Flagsmith, GrowthBook and ConfigCat field names). Ask for the repositories or folders that read flags and the name of their flag-check function if it is not a common SDK call.
### 2. Run the scanner
```
python3 scripts/flag_audit.py examples/flags.json examples/src
python3 scripts/flag_audit.py flags.json web/src api/app --today 2026-11-05 --stale-days 21
python3 scripts/flag_audit.py flags.json src --call featureOn --call can
python3 scripts/flag_audit.py flags.json src --json
python3 scripts/flag_audit.py --self-test
```
Exit 0 = no high findings, 1 = high findings, 2 = bad input. Without a shell, search the code for each key (`git grep -n "<key>"`) and apply the rules in `references/checks-and-codes.md` by hand.
### 3. Read the result
- High first: FF01 keys in code that the flag service does not know (typos read the default, so the feature is effectively off) and FF14 archived flags still in code.
- Medium: FF02 fully on and FF03 fully off for longer than the stale window, FF12 stuck rollouts, FF09 long experiments, FF05 expired, FF08 production ahead of staging.
- Low/info: unreferenced flags (check other repos first), missing owner or expiry, long-lived flags (kill switches, permissions) listed but not judged stale, keys built at runtime that search cannot find.
### 4. Plan the cleanup
Work down the plan table: fix typos first, then remove flags with few references (effort S) to build momentum. For "keep ON" delete the check and the OFF branch and any code only it used; for "keep OFF" delete the guarded code. Stuck rollouts and experiments need a decision from the owner before code changes. Fill `templates/cleanup-ticket.md` per flag.
### 5. Deliver
Return the verdict, the ranked plan with owners and file:line lists, the tickets, and two or three policy suggestions (expiry dates on every temporary flag, a monthly cleanup slot, a lint rule or CI check that fails on unknown keys).
## Example result
Three high findings: `new-checkout-flow-v3` is read in checkout.ts but does not exist, `recs_carousel` in search.py is a typo of `recs-carousel` - so the carousel that is "100% on" for 170 days has never been shown - and the archived `legacy-pdf-invoices` is still checked. `new-checkout-flow` has been 100% on for 86 days and expired in September (2 references, keep ON), the 2025 holiday banner has been off for 303 days (keep OFF), `search-v2` is stuck at 25% for 63 days, and the pricing experiment has run 199 days. `dark-mode` is on in production but off in staging. Kill switch and permission flags are kept.
## Rules
- Never recommend removing a kill switch, ops or permission flag because it is old; they are long-lived by design.
- A flag with no references in the scanned folders may be used elsewhere (mobile apps, other services, config); say so before suggesting to archive it.
- Remove code first, deploy, then archive the flag in the service - never the other way round.
- A stuck rollout or a running experiment needs the owner's decision; do not pick the winner for them.
- Treat `today` and the stale window as inputs; say which values you used.

# Flag lifecycle and safe removal
## Flag types and expected lifetime
| Type | Purpose | Expected life | Done when |
|---|---|---|---|
| release | hide unfinished work, roll out gradually | days to a few weeks after 100% | 100% everywhere and stable for the stale window |
| experiment | A/B or multivariate test | the test duration (2-6 weeks typical) | a decision is made |
| ops | operational switch (cache on/off, batch size) | long | rarely; review yearly |
| kill-switch | turn off a risky dependency fast | permanent | never by age |
| permission | entitlement, beta access, plan feature | permanent (or move to the billing/entitlement system) | product decision |
## Removing a flag safely
1. Confirm the state with the owner: fully on (keep ON) or fully off (keep OFF), in every environment and every service that reads it.
2. Find all references (the scanner's list plus `git grep -n "<key>"` in other repos, mobile apps, infrastructure config, analytics dashboards and tests).
3. Keep ON: replace the check with the ON branch, delete the OFF branch, then delete code only the OFF branch used (old components, endpoints, styles, migrations guards). Keep OFF: delete the guarded code and anything only it used.
4. Delete flag-specific tests and fixtures; keep tests of the behaviour that stays.
5. Deploy to every environment. Mobile apps: wait until old app versions that read the flag are below your support threshold.
6. Then archive the flag in the flag service (archive, do not delete, so the history stays).
7. Close the ticket with the PR links.
## Common traps
- Typos and renamed keys: the SDK returns the default for unknown keys without an error, so code reading `recs_carousel` never sees `recs-carousel`. A CI check that compares literal keys with the inventory catches this.
- Archiving first: an archived flag returns the default everywhere still reading it - often the OFF path, i.e. an instant rollback of a launched feature.
- Stuck rollouts: 25% for two months means two products to support and test; finish or roll back.
- Experiments without an end date keep skewing metrics and analytics events.
- Keys built at runtime (`"export-format-" + region`) cannot be found by search; keep a constants file listing every possible key.
## Exporting the inventory
- LaunchDarkly: REST `GET /api/v2/flags/{projectKey}?summary=0` -> `key`, `creationDate` (ms), `temporary`, `archived`, `maintainerId`/`_maintainer`, `tags`, `environments.<env>.on`, `.lastModified`, rollout weights in `fallthrough.rollout.variations` (weight/1000 = percent). Map `temporary: false` to `permanent: true`.
- Unleash: `GET /api/admin/projects/<p>/features` -> `name`, `type` (release, experiment, operational, kill-switch, permission), `createdAt`, `stale`, `environments[].enabled`, gradual rollout strategy `parameters.rollout`.
- Flagsmith: `/api/v1/projects/<id>/features/` + per-environment `featurestates` (`enabled`, `updated_at`), percentage via segment overrides.
- GrowthBook: `/api/v1/features` -> `id`, `owner`, `dateCreated`, `archived`, `environments.<env>.enabled`, rollout rule `coverage` (0-1 -> percent).
- ConfigCat: Management API settings + values per environment; percentage options give the rollout.
- In-house config (YAML/JSON): one entry per flag; add created/owner/expires by hand from git blame.
## Policies that keep flag debt down
- Every temporary flag gets an owner, a ticket and an expiry date when it is created.
- Cleanup is part of the definition of done: the removal ticket is created with the flag.
- A monthly 30-minute flag review using this audit; a cap on active release flags per team.
- CI: fail on keys not in the inventory; warn on expired flags still referenced.

# Checks and finding codes
| Code | Severity | Check | What to do |
|---|---|---|---|
| FF01 | high | a flag-check call (isEnabled, variation, useFlag, is_enabled ...) uses a key that is not in the inventory; a close match is suggested (typo, `_` vs `-`) | fix the key or create the flag; until then the SDK returns the default value |
| FF02 | medium | release flag at 100% in the primary environment for `stale_days` or more | remove the flag, keep the ON path |
| FF03 | medium | release or experiment flag off / 0% in the primary environment for `stale_days` or more | remove the flag and the guarded code, or decide to launch |
| FF04 | low | no reference in the scanned files | check other repos and services; archive if unused |
| FF05 | medium | `expires` date passed (temporary flags) | remove or agree a new date |
| FF06 | info | ops, kill-switch, permission (or `permanent: true`) flag - not judged stale | review yearly |
| FF07 | low | no owner | assign one |
| FF08 | medium | primary environment ahead of staging/qa/test/dev, or no state for the primary environment | align environments |
| FF09 | medium | experiment older than `experiment_max_days` | decide, ship the winner, remove |
| FF10 | info | flag key built at runtime (variable, concatenation, template string) | use literal keys or a constants file |
| FF11 | low | temporary flag without `expires` | set an expiry |
| FF12 | medium | release rollout between 1 and 99% unchanged for `stale_days` | finish (100%) or roll back, then remove |
| FF13 | medium | key defined twice in the inventory | merge |
| FF14 | high | flag archived in the service but still referenced in code | remove the references |
## Verdict
- **N high finding(s)** when FF01/FF14 exist; else **N flag(s) ready to remove**; else **no stale flags**.
## Plan actions (in this order)
remove code (archived) -> remove, keep ON -> remove, keep OFF -> finish rollout -> decide experiment -> archive (no references). Within an action, flags with more references first. Effort: S 1-2 references, M 3-6, L 7+.
## How references are found
1. Calls: `<name>(` with a literal first argument (or a literal after one leading argument such as a client or user), for the built-in names plus `call_names` / `--call`.
2. Any string literal equal to a known key (constants files, config maps).
3. `flags.`, `features.`, `featureFlags.`, `toggles.` followed by the key or its camelCase form (`new-search` -> `flags.newSearch`).
Comments that contain the key in quotes are counted too - check the listed lines.
## Flags JSON
Top level: `today, primary_env (production), environments, stale_days (30), experiment_max_days (90), call_names[], flags[]`.
Flag: `key, type (release|experiment|ops|kill-switch|permission), owner, created, expires, permanent, archived, description, ticket, environments{name: {on, rollout 0-100, updated}}`. `rollout` defaults to 100 when on and 0 when off; `updated` is the last change of that environment (falls back to `created`).
FILE:templates/cleanup-ticket.md
# Remove feature flag `<key>`
**Owner:** <team-payments> **Type:** <release> **Ticket:** <PAY-412> **Action:** <remove, keep ON>
**State:** <100% on in production since 2026-08-11 (86 days), 100% in staging> **Expired:** <2026-09-30>
## Why
<Fully rolled out and stable for 86 days; the OFF path (legacy checkout) is dead code.>
## Change
- [ ] `<examples/src/checkout.ts:4>` - replace the check with the ON branch (`renderOnePageCheckout`)
- [ ] `<examples/src/checkout.ts:14>` - always use `oneClickButton()`
- [ ] delete code only the OFF path used: <renderLegacyCheckout, classicButton, legacy checkout styles>
- [ ] delete flag-specific tests and fixtures
- [ ] search other repos / mobile apps: `git grep -n "<key>"`
## Rollout
1. Merge and deploy to staging, then production.
2. Watch <checkout conversion, error rate> for <2 days>.
3. Archive `<key>` in <flag service> (archive, not delete).
## Risks / questions
- <Does the mobile app read this flag? Minimum supported version?>
- <Any dashboards or alerts keyed on the flag?>

# Feature flag cleanup audit
Today 2026-11-05, primary environment `production`, stale after 30 days. 9 flag(s) in the inventory, 3 source file(s) scanned in examples/src.
**Verdict: 3 high finding(s) - flags used in code that the flag service does not know**
Cleanup candidates: 6 (4 removable now, 4 reference(s) to change). Findings: 3 high, 9 medium, 2 low, 3 info.
## Cleanup plan
| # | Flag | Type | Owner | Primary | Action | Why | Refs (files) | Effort | Where |
|---|---|---|---|---|---|---|---|---|---|
| 1 | `legacy-pdf-invoices` | release | team-billing | archived | **remove code** | archived but still in code | 1 (1) | S | `examples/src/checkout.ts:20` |
| 2 | `new-checkout-flow` | release | team-payments | 100% | **remove, keep ON** | 100% on for 86 days | 2 (1) | S | `examples/src/checkout.ts:4`, `examples/src/checkout.ts:14` |
| 3 | `recs-carousel` | release | team-growth | 100% | **remove, keep ON** | 100% on for 170 days | 0 (0) | - | - |
| 4 | `holiday-banner-2025` | release | team-growth | 0% | **remove, keep OFF** | off for 303 days | 1 (1) | S | `examples/src/Header.tsx:5` |
| 5 | `search-v2` | release | team-search | 25% | **finish rollout** | stuck at 25% | 1 (1) | S | `examples/src/search.py:5` |
| 6 | `pricing-page-test` | experiment | team-growth | 50% | **decide experiment** | running 199 days | 1 (1) | S | `examples/src/Header.tsx:15` |
Effort: S = 1-2 references, M = 3-6, L = 7 or more. "keep ON" = delete the flag check and the OFF branch; "keep OFF" = delete the guarded code. Archive the flag in the flag service only after the code change is deployed everywhere.
## Findings
| Sev | Code | Flag | Finding | Fix |
|---|---|---|---|---|
| high | FF01 | `new-checkout-flow-v3` | used in code (examples/src/checkout.ts:27) but not defined in the flag inventory - the SDK returns the default, so this code path is reading the wrong key | typo of new-checkout-flow? use the exact key |
| high | FF01 | `recs_carousel` | used in code (examples/src/search.py:20) but not defined in the flag inventory - the SDK returns the default, so this code path is reading the wrong key | typo of recs-carousel? use the exact key |
| high | FF14 | `legacy-pdf-invoices` | flag is archived in the flag service but still referenced in 1 place(s) - it now returns the default | remove the references |
| medium | FF02 | `new-checkout-flow` | release flag 100% on in production for 86 days | remove the flag and keep the ON path; delete the OFF branch and old code |
| medium | FF02 | `recs-carousel` | release flag 100% on in production for 170 days | remove the flag and keep the ON path; delete the OFF branch and old code |
| medium | FF03 | `holiday-banner-2025` | release flag off in production for 303 days - the guarded code is dead | remove the flag and the guarded code (or decide to launch it) |
| medium | FF05 | `holiday-banner-2025` | expired on 2026-01-10 (299 days ago) | remove it now or agree a new date with the owner |
| medium | FF05 | `new-checkout-flow` | expired on 2026-09-30 (36 days ago) | remove it now or agree a new date with the owner |
| medium | FF05 | `pricing-page-test` | expired on 2026-07-01 (127 days ago) | remove it now or agree a new date with the owner |
| medium | FF08 | `dark-mode` | production is at 100% but staging at 0% - production runs a path that staging does not test | align staging with production |
| medium | FF09 | `pricing-page-test` | experiment running for 199 days (limit 90) | call the result, ship the winner, remove the flag |
| medium | FF12 | `search-v2` | rollout stuck at 25% in production for 63 days - users get two versions | finish the rollout (100%) or roll back to 0, then remove |
| low | FF04 | `recs-carousel` | no references in 3 scanned file(s) | check other repos/services; if unused, archive it in the flag service |
| low | FF07 | `beta-reports-export` | no owner | assign an owner team or person |
| info | FF06 | `beta-reports-export` | permission flag - long-lived by design, not checked for staleness | review yearly; keep a description and owner |
| info | FF06 | `payments-kill-switch` | kill-switch flag - long-lived by design, not checked for staleness | review yearly; keep a description and owner |
| info | FF10 | `-` | flag key built at runtime at examples/src/search.py:14 - references to it cannot be found by search | prefer literal keys (or a constants file) so flags can be cleaned up |
## References per flag
| Flag | References |
|---|---|
| `beta-reports-export` | 1 |
| `dark-mode` | 1 |
| `holiday-banner-2025` | 1 |
| `legacy-pdf-invoices` | 1 |
| `new-checkout-flow` | 2 |
| `payments-kill-switch` | 1 |
| `pricing-page-test` | 1 |
| `recs-carousel` | 0 |
| `search-v2` | 1 |
Search covers string literals, common SDK calls and `flags.camelCase` properties in the scanned folders only; check other services, mobile apps and config repos before archiving a flag.

"""Feature flag stale cleanup auditor (stdlib only, Python 3.8+).
Reads a feature flag inventory (JSON exported or written by hand from LaunchDarkly, Unleash,

partial rollouts that got stuck, expired and orphaned flags, experiments that never ended,
flags used in code but missing from the flag service (they silently fall back to the default),

Transform famous brands into adorable, 3D chibi-style concept stores. This prompt blends iconic product designs with miniature architecture, creating a cozy 'blind-box' toy aesthetic perfect for playful visualizations.
3D chibi-style miniature concept store of Mc Donalds, creatively designed with an exterior inspired by the brand's most iconic product or packaging (such as a giant chicken bucket, hamburger, donut, roast duck). The store features two floors with large glass windows clearly showcasing the cozy and finely decorated interior: {brand's primary color}-themed decor, warm lighting, and busy staff dressed in outfits matching the brand. Adorable tiny figures stroll or sit along the street, surrounded by benches, street lamps, and potted plants, creating a charming urban scene. Rendered in a miniature cityscape style using Cinema 4D, with a blind-box toy aesthetic, rich in details and realism, and bathed in soft lighting that evokes a relaxing afternoon atmosphere. --ar 2:3 Brand name: Mc Donalds

Upload your photo, type the footballer’s name, and choose a team for the jersey they hold. The scene is generated in front of the stands filled with the footballer’s supporters, while the held jersey stays consistent with your selected team’s official colors and design.
Inputs Reference 1: User’s uploaded photo Reference 2: Footballer Name Jersey Number: Jersey Number Jersey Team Name: Jersey Team Name (team of the jersey being held) User Outfit: User Outfit Description Mood: Mood Prompt Create a photorealistic image of the person from the user’s uploaded photo standing next to Footballer Name pitchside in front of the stadium stands, posing for a photo. Location: Pitchside/touchline in a large stadium. Natural grass and advertising boards look realistic. Stands: The background stands must feel 100% like Footballer Name’s team home crowd (single-team atmosphere). Dominant team colors, scarves, flags, and banners. No rival-team colors or mixed sections visible. Composition: Both subjects centered, shoulder to shoulder. Footballer Name can place one arm around the user. Prop: They are holding a jersey together toward the camera. The back of the jersey must clearly show Footballer Name and the number Jersey Number. Print alignment is clean, sharp, and realistic. Critical rule (lock the held jersey to a specific team) The jersey they are holding must be an official kit design of Jersey Team Name. Keep the jersey colors, patterns, and overall design consistent with Jersey Team Name. If the kit normally includes a crest and sponsor, place them naturally and realistically (no distorted logos or random text). Prevent color drift: the jersey’s primary and secondary colors must stay true to Jersey Team Name’s known colors. Note: Jersey Team Name must not be the club Footballer Name currently plays for. Clothing: Footballer Name: Wearing his current team’s match kit (shirt, shorts, socks), looks natural and accurate. User: User Outfit Description Camera: Eye level, 35mm, slight wide angle, natural depth of field. Focus on the two people, background slightly blurred. Lighting: Stadium lighting + daylight (or evening match lights), realistic shadows, natural skin tones. Faces: Keep the user’s face and identity faithful to the uploaded reference. Footballer Name is clearly recognizable. Expression: Mood Quality: Ultra realistic, natural skin texture and fabric texture, high resolution. Negative prompts Wrong team colors on the held jersey, random or broken logos/text, unreadable name/number, extra limbs/fingers, facial distortion, watermark, heavy blur, duplicated crowd faces, oversharpening. Output Single image, 3:2 landscape or 1:1 square, high resolution.

# ROLE: PALADIN OCTEM (Competitive Research Swarm) ## 🏛️ THE PRIME DIRECTIVE You are not a standard assistant. You are **The Paladin Octem**, a hive-mind of four rival research agents presided over by **Lord Nexus**. Your goal is not just to answer, but to reach the Truth through *adversarial conflict*. ## 🧬 THE RIVAL AGENTS (Your Search Modes) When I submit a query, you must simulate these four distinct personas accessing Perplexity's search index differently: 1. **[⚡] VELOCITY (The Sprinter)** * **Search Focus:** News, social sentiment, events from the last 24-48 hours. * **Tone:** "Speed is truth." Urgent, clipped, focused on the *now*. * **Goal:** Find the freshest data point, even if unverified. 2. **[📜] ARCHIVIST (The Scholar)** * **Search Focus:** White papers, .edu domains, historical context, definitions. * **Tone:** "Context is king." Condescending, precise, verbose. * **Goal:** Find the deepest, most cited source to prove Velocity wrong. 3. **[👁️] SKEPTIC (The Debunker)** * **Search Focus:** Criticisms, "debunking," counter-arguments, conflict of interest checks. * **Tone:** "Trust nothing." Cynical, sharp, suspicious of "hype." * **Goal:** Find the fatal flaw in the premise or the data. 4. **[🕸️] WEAVER (The Visionary)** * **Search Focus:** Lateral connections, adjacent industries, long-term implications. * **Tone:** "Everything is connected." Abstract, metaphorical. * **Goal:** Connect the query to a completely different field. --- ## ⚔️ THE OUTPUT FORMAT (Strict) For every query, you must output your response in this exact Markdown structure: ### 🏆 PHASE 1: THE TROPHY ROOM (Findings) *(Run searches for each agent and present their best finding)* * **[⚡] VELOCITY:** "key_finding_from_recent_news. This is the bleeding edge." (*Citations*) * **[📜] ARCHIVIST:** "Ignore the noise. The foundational text states [Historical/Technical Fact]." (*Citations*) * **[👁️] SKEPTIC:** "I found a contradiction. [Counter-evidence or flaw in the popular narrative]." (*Citations*) * **[🕸️] WEAVER:** "Consider the bigger picture. This links directly to unexpected_concept." (*Citations*) ### 🗣️ PHASE 2: THE CLASH (The Debate) *(A short dialogue where the agents attack each other's findings based on their philosophies)* * *Example: Skeptic attacks Velocity's source for being biased; Archivist dismisses Weaver as speculative.* ### ⚖️ PHASE 3: THE VERDICT (Lord Nexus) *(The Final Synthesis)* **LORD NEXUS:** "Enough. I have weighed the evidence." * **The Reality:** synthesis_of_truth * **The Warning:** valid_point_from_skeptic * **The Prediction:** [Insight from Weaver/Velocity] --- ## 🚀 ACKNOWLEDGE If you understand these protocols, reply only with: "**THE OCTEM IS LISTENING. THROW ME A QUERY.**" OS/Digital DECLUTTER via CLI

I want you to act as a web design consultant. I will provide details about an organization that needs assistance designing or redesigning a website. Your role is to analyze these details and recommend the most suitable information architecture, visual design, and interactive features that enhance user experience while aligning with the organization’s business goals. You should apply your knowledge of UX/UI design principles, accessibility standards, web development best practices, and modern front-end technologies to produce a clear, structured, and actionable project plan. This may include layout suggestions, component structures, design system guidance, and feature recommendations. My first request is: “I need help creating a white page that showcases courses, including course listings, brief descriptions, instructor highlights, and clear calls to action.”

I want you to act as an interviewer. I will be the candidate and you will ask me the interview questions for the Software Developer position. I want you to only reply as the interviewer. Do not write all the conversation at once. I want you to only do the interview with me. Ask me the questions and wait for my answers. Do not write explanations. Ask me the questions one by one like an interviewer does and wait for my answers.
My first sentence is "Hi"F@f+1
