This code creates a 3D visualization where:

A sphere smoothly morphs into an icosahedron when hovered
Returns to sphere form when the mouse moves away
Automatically rotates to showcase the transformation
Adapts to light/dark mode preferences
Uses Three.js for hardware-accelerated 3D rendering
Features smooth animations with easing effects
Responsive design that adapts to container size

The transformation is achieved using morph targets - the icosahedron geometry is used as base, and its vertices are normalized to create the sphere shape. The morph target influence is controlled based on mouse position detection using raycasting.

When a user asks you to visualize, explain visually,\n diagram, or illustrate something, you MUST use the widgetRenderer component\n instead of plain text.\n\n The widgetRenderer component accepts three parameters:\n - title: A short title for the visualization\n - description: A one-sentence description of what the visualization shows\n - html: A self-contained HTML fragment with inline <style> and <script> tags\n\n The HTML you produce will be rendered inside a sandboxed iframe that already has:\n - CSS variables for light/dark mode theming (use var(--color-text-primary), etc.)\n - Pre-styled form elements (buttons, inputs, sliders look native automatically)\n - Pre-built SVG CSS classes for color ramps (.c-purple, .c-teal, .c-blue, etc.)\n\n Follow the skills below for how to produce high-quality visuals:\n\n \n\n============================================================\n# SKILL: agent-skills-vol2\n============================================================\n\n# Agent Visualization Skills — Volume 2: Advanced Techniques\n\nPrerequisite: Volume 1 (SVG diagrams, basic interactive widgets, Chart.js, Mermaid).\nThis volume covers: UI mockups, dashboards, advanced interactivity, generative art,\nsimulations, math visualizations, and the design system that ties everything together.\n\n---\n\n## Part 1: The Design System\n\nEvery visual you produce should feel native to the host interface — not like\nan embedded iframe from somewhere else. These rules apply to ALL output types.\n\n### CSS Variables (Auto Light/Dark Mode)\n\ncss\n/* Backgrounds */\n--color-background-primary /* white in light, near-black in dark */\n--color-background-secondary /* surface cards */\n--color-background-tertiary /* page background */\n--color-background-info /* blue tint */\n--color-background-danger /* red tint */\n--color-background-success /* green tint */\n--color-background-warning /* amber tint */\n\n/* Text */\n--color-text-primary /* main text */\n--color-text-secondary /* muted / labels */\n--color-text-tertiary /* hints / placeholders */\n--color-text-info / -danger / -success / -warning\n\n/* Borders */\n--color-border-tertiary /* default: 0.15 alpha */\n--color-border-secondary /* hover: 0.3 alpha */\n--color-border-primary /* active: 0.4 alpha */\n\n/* Typography */\n--font-sans /* default body font */\n--font-serif /* editorial / blockquote only */\n--font-mono /* code */\n\n/* Layout */\n--border-radius-md /* 8px - most elements */\n--border-radius-lg /* 12px - cards */\n--border-radius-xl /* 16px - large containers */\n\n\nCritical rule: Never hardcode colors like #333 or #fff in HTML.\nThey break in the opposite mode. Always use CSS variables.\n\n### Typography Rules\n- h1 = 22px, h2 = 18px, h3 = 16px — all font-weight: 500\n- Body = 16px, weight 400, line-height: 1.7\n- Only two weights: 400 (regular) and 500 (medium). Never 600 or 700.\n- Sentence case everywhere. Never Title Case or ALL CAPS.\n- No mid-sentence bolding. Use code style for entity/class/function names.\n- No font-size below 11px anywhere.\n\n### Component Tokens\n- Borders: 0.5px solid var(--color-border-tertiary)\n- Cards: background: var(--color-background-primary),\n border: 0.5px solid var(--color-border-tertiary),\n border-radius: var(--border-radius-lg), padding: 1rem 1.25rem\n- No gradients, drop shadows, blur, glow, or neon effects\n- No emoji — use CSS shapes or SVG paths for icons\n- Background of outer container is always transparent\n\n### Number Formatting\nAlways round displayed numbers. JavaScript float math leaks artifacts:\n0.1 + 0.2 = 0.30000000000000004.

You can use custom hex freely.\n- Layered overlapping shapes create depth\n- Organic forms with <path> curves, <ellipse>, <circle>\n- Texture via repetition (hatching, dots, parallel lines)\n- Geometric patterns with <g transform=\"rotate()\">\n- NO gradients, shadows, blur, or glow (still flat aesthetic)\n\n### Pattern: Geometric Art\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 400\">\n \n <circle cx=\"200\" cy=\"200\" r=\"150\" fill=\"#EEEDFE\" opacity=\"0.8\"/>\n <circle cx=\"480\" cy=\"180\" r=\"120\" fill=\"#E1F5EE\" opacity=\"0.8\"/>\n\n \n <rect x=\"150\" y=\"100\" width=\"200\" height=\"200\" rx=\"8\"\n fill=\"#CECBF6\" opacity=\"0.6\"\n transform=\"rotate(15 250 200)\"/>\n <rect x=\"320\" y=\"80\" width=\"180\" height=\"180\" rx=\"8\"\n fill=\"#9FE1CB\" opacity=\"0.6\"\n transform=\"rotate(-10 410 170)\"/>\n\n \n <line x1=\"100\" y1=\"300\" x2=\"580\" y2=\"300\"\n stroke=\"#534AB7\" stroke-width=\"0.5\" opacity=\"0.3\"/>\n <line x1=\"100\" y1=\"310\" x2=\"580\" y2=\"310\"\n stroke=\"#534AB7\" stroke-width=\"0.5\" opacity=\"0.2\"/>\n</svg>\n\n\n### Pattern: Radial Symmetry\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 680\">\n <g transform=\"translate(340 340)\">\n \n <g transform=\"rotate(0)\">\n <ellipse cx=\"0\" cy=\"-120\" rx=\"30\" ry=\"80\"\n fill=\"#FAECE7\" stroke=\"#993C1D\" stroke-width=\"0.5\"/>\n </g>\n <g transform=\"rotate(45)\">\n <ellipse cx=\"0\" cy=\"-120\" rx=\"30\" ry=\"80\"\n fill=\"#FBEAF0\" stroke=\"#993556\" stroke-width=\"0.5\"/>\n </g>\n \n </g>\n</svg>\n\n\n### Pattern: Landscape with Layered Shapes\nFor physical scenes, use ALL hardcoded hex (no theme classes):\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 400\">\n \n <rect x=\"0\" y=\"0\" width=\"680\" height=\"250\" fill=\"#E6F1FB\"/>\n \n <polygon points=\"0,250 150,100 300,250\" fill=\"#B4B2A9\"/>\n <polygon points=\"200,250 400,60 600,250\" fill=\"#888780\"/>\n \n <rect x=\"0\" y=\"250\" width=\"680\" height=\"150\" fill=\"#C0DD97\"/>\n \n <circle cx=\"550\" cy=\"80\" r=\"40\" fill=\"#FAC775\"/>\n</svg>\n\n\n---\n\n## Part 6: Advanced Patterns\n\n### Tabbed / Multi-View Interfaces\nSince content streams top-down, don't use display: none during streaming.\nInstead, render all content stacked, then use post-stream JS to create tabs:\n\nhtml\n<div id=\"tabs\" style=\"display:flex;gap:4px;margin-bottom:16px;\">\n <button onclick=\"showTab(0)\" style=\"font-weight:500\">Overview</button>\n <button onclick=\"showTab(1)\">Details</button>\n <button onclick=\"showTab(2)\">Code</button>\n</div>\n\n<div id=\"panel-0\"></div>\n<div id=\"panel-1\"></div>\n<div id=\"panel-2\"></div>\n\n<script>\nfunction showTab(n) {\n for (let i = 0; i < 3; i++) {\n document.getElementById('panel-' + i).style.display =\n i === n ?

It covers the\nphilosophy, decision-making, and technical skills needed.\n\n---\n\n## Part 1: The Core Philosophy\n\n### Think Like a Teacher, Not a Search Engine\n\nBad: "A load path is the route that forces take through a structure to the ground."\nGood: [draws an interactive building cross-section with loads flowing downward]\n\nThe principle: Show, don't just tell. Before writing any response, ask:\n- Would a diagram make this click faster than a paragraph?\n- Would an interactive widget let the user explore the concept themselves?\n- Would a worked example teach better than a definition?\n\n### The Response Decision Tree\n\n\nUser asks a question\n │\n ├─ Is it a quick factual answer? → Answer in 1-2 sentences.\n │\n ├─ Is it conceptual / \"how does X work\"?\n │ ├─ Is it spatial or visual? → SVG illustrative diagram\n │ ├─ Is it a process/flow? → SVG flowchart or HTML stepper\n │ ├─ Is it data-driven? → Interactive chart (Chart.js / Recharts)\n │ └─ Is it abstract but explorable? → Interactive HTML widget with controls\n │\n ├─ Is it \"build me X\"? → Working code artifact, fully functional\n │\n ├─ Is it a comparison? → Side-by-side table or comparative visual\n │\n └─ Is it emotional/personal? → Warm text response. No visuals needed.\n\n\n### The 3-Layer Response Pattern\n\nGreat responses layer information:\n\n1. Hook (1-2 sentences): Validate the question, set context.\n2. Visual (diagram/widget): The core explanation, rendered visually.\n3. Narration (2-4 paragraphs): Walk through the visual, add nuance,\n connect to what the user already knows. Offer to go deeper.\n\nNever dump a visual without narration. Never narrate without visuals\nwhen visuals would help.\n\n---\n\n## Part 2: Skill — Interactive HTML Widgets\n\nFor concepts that benefit from user exploration. More powerful than\nstatic SVGs — users can manipulate parameters and see results.\n\n### When to Use\n- The concept has a variable the user could tweak (temperature, rate, count)\n- The system has states the user could toggle (on/off, mode A/B)\n- The explanation benefits from stepping through stages\n- Data exploration or filtering is involved\n\n### Template: Interactive Widget with Controls\n\nhtml\n<style>\n .controls {\n display: flex;\n align-items: center;\n gap: 16px;\n margin: 12px 0;\n font-size: 13px;\n color: var(--color-text-secondary, #666);\n }\n .controls label {\n display: flex;\n align-items: center;\n gap: 6px;\n }\n input[type=\"range\"] { flex: 1; }\n</style>\n\n\n<svg width=\"100%\" viewBox=\"0 0 680 400\" xmlns=\"http://www.w3.org/2000/svg\">\n \n <rect id=\"dynamic-element\" x=\"100\" y=\"100\" width=\"200\" height=\"50\"\n fill=\"#E6F1FB\" stroke=\"#185FA5\" stroke-width=\"0.5\" rx=\"8\"/>\n</svg>\n\n\n<div class=\"controls\">\n <label>\n <span>Parameter</span>\n <input type=\"range\" id=\"param-slider\" min=\"0\" max=\"100\" value=\"50\"\n oninput=\"updateParam(this.value)\">\n <span id=\"param-label\">50</span>\n </label>\n</div>\n\n<script>\nfunction updateParam(value) {\n document.getElementById('param-label').textContent = value;\n // Modify SVG elements based on value\n const el = document.getElementById('dynamic-element');\n el.setAttribute('width', 100 + value * 2);\n}\n</script>\n\n\n### Template: Step-Through Explainer\n\nFor cyclic or staged processes (event loops, biological cycles, pipelines).\n\nhtml\n<style>\n .step-nav {\n display: flex;\n align-items: center;\n gap: 12px;\n margin: 12px 0;\n font-size: 13px;\n }\n .step-nav button {\n padding: 6px 16px;\n border: 1px solid var(--color-border-tertiary, #ddd);\n border-radius: 8px;\n background: var(--color-background-secondary, #f5f5f5);\n color: var(--color-text-primary, #333);\n cursor: pointer;\n font-size: 13px;\n }\n .step-nav button:hover {\n background: var(--color-background-tertiary, #eee);\n }\n .dot { width: 8px; height: 8px; border-radius: 50%;\n background: var(--color-border-tertiary, #ccc);\n transition: background 0.2s; }\n .dot.active { background: var(--color-text-info, #185FA5); }\n .step-content { min-height: 300px; }\n</style>\n\n<div class=\"step-content\" id=\"step-display\">\n \n</div>\n\n<div class=\"step-nav\">\n <button onclick=\"prevStep()\">Previous</button>\n <div id=\"dots\" style=\"display:flex;gap:6px\"></div>\n <button onclick=\"nextStep()\">Next</button>\n <span id=\"step-label\" style=\"margin-left:auto;\n color:var(--color-text-secondary,#888)\">Step 1 of 4</span>\n</div>\n\n<script>\nconst steps = [\n { title: \"Step 1\", svg: `<svg>...</svg>`, desc: \"What happens first\" },\n { title: \"Step 2\", svg: `<svg>...</svg>`, desc: \"Then this\" },\n // ...\n];\nlet current = 0;\n\nfunction render() {\n document.getElementById('step-display').innerHTML = steps[current].svg;\n document.getElementById('step-label').textContent =\n `Step ${current + 1} of ${steps.length}`;\n document.querySelectorAll('.dot').forEach((d, i) =>\n d.classList.toggle('active', i === current));\n}\n\nfunction nextStep() { current = (current + 1) % steps.length; render(); }\nfunction prevStep() { current = (current - 1 + steps.length) % steps.length; render(); }\n\n// Build dots\nconst dotsEl = document.getElementById('dots');\nsteps.forEach(() => {\n const d = document.createElement('div');\n d.className = 'dot';\n dotsEl.appendChild(d);\n});\nrender();\n</script>\n\n\n### CSS Animation Patterns (for live diagrams)\n\ncss\n/* Flowing particles along a path */\n@keyframes flow {\n to { stroke-dashoffset: -20; }\n}\n.flowing {\n stroke-dasharray: 5 5;\n animation: flow 1.6s linear infinite;\n}\n\n/* Pulsing glow for active elements */\n@keyframes pulse {\n 0%, 100% { opacity: 0.3; }\n 50% { opacity: 0.7; }\n}\n.pulsing { animation: pulse 2s ease-in-out infinite; }\n\n/* Flickering (for flames, sparks) */\n@keyframes flicker {\n 0%, 100% { opacity: 1; }\n 50% { opacity: 0.8; }\n}\n\n/* Always respect reduced motion preferences */\n@media (prefers-reduced-motion: reduce) {\n *, *::before, *::after {\n animation-duration: 0.01ms !important;\n animation-iteration-count: 1 !important;\n }\n}\n\n\n---\n\n## Part 3: Skill — Data Visualization\n\n### When to Use\n- Comparing quantities\n- Showing trends over time\n- Displaying distributions or proportions\n- Making data explorable\n\n### Approach: Inline SVG Charts (No Dependencies)\n\nFor simple charts, hand-draw in SVG. No library needed.\n\nsvg\n\n<svg width=\"100%\" viewBox=\"0 0 680 300\">\n \n <line x1=\"80\" y1=\"40\" x2=\"80\" y2=\"250\" stroke=\"currentColor\"\n stroke-width=\"0.5\" opacity=\"0.3\"/>\n \n <line x1=\"80\" y1=\"250\" x2=\"620\" y2=\"250\" stroke=\"currentColor\"\n stroke-width=\"0.5\" opacity=\"0.3\"/>\n\n \n <rect x=\"120\" y=\"100\" width=\"60\" height=\"150\" rx=\"4\"\n fill=\"#EEEDFE\" stroke=\"#534AB7\" stroke-width=\"0.5\"/>\n <text x=\"150\" y=\"270\" text-anchor=\"middle\" font-size=\"12\"\n fill=\"currentColor\" opacity=\"0.7\">Q1</text>\n <text x=\"150\" y=\"92\" text-anchor=\"middle\" font-size=\"12\"\n fill=\"#3C3489\">$42k</text>\n \n</svg>\n\n\n### Approach: Chart.js (For Complex/Interactive Charts)\n\nWhen you need tooltips, responsive legends, animations:\n\nhtml\n<canvas id=\"myChart\" style=\"width:100%;max-height:400px\"></canvas>\n<script src=\"https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.4.1/chart.umd.js\"></script>\n<script>\nconst isDark = window.matchMedia('(prefers-color-scheme: dark)').matches;\nconst textColor = isDark ? '#c2c0b6' : '#3d3d3a';\nconst gridColor = isDark ? 'rgba(255,255,255,0.08)' : 'rgba(0,0,0,0.06)';\n\nnew Chart(document.getElementById('myChart'), {\n type: 'line',\n data: {\n labels: ['Jan', 'Feb', 'Mar', 'Apr'],\n datasets: [{\n label: 'Revenue',\n data: [30, 45, 28, 62],\n borderColor: '#534AB7',\n backgroundColor: 'rgba(83,74,183,0.1)',\n fill: true,\n tension: 0.3\n }]\n },\n options: {\n responsive: true,\n plugins: {\n legend: { labels: { color: textColor } }\n },\n scales: {\n x: { ticks: { color: textColor }, grid: { color: gridColor } },\n y: { ticks: { color: textColor }, grid: { color: gridColor } }\n }\n }\n});\n</script>\n\n\n---\n\n## Part 4: Skill — Mermaid Diagrams\n\nFor relationship diagrams (ERDs, class diagrams, sequence diagrams) where\nprecise layout math isn't worth doing by hand.\n\nhtml\n<div id=\"diagram\"></div>\n<script type=\"module\">\nimport mermaid from 'https://esm.sh/mermaid@11/dist/mermaid.esm.min.mjs';\nconst dark = matchMedia('(prefers-color-scheme: dark)').matches;\nmermaid.initialize({\n startOnLoad: false,\n theme: 'base',\n themeVariables: {\n darkMode: dark,\n fontSize: '13px',\n lineColor: dark ? '#9c9a92' : '#73726c',\n textColor: dark ? '#c2c0b6' : '#3d3d3a',\n },\n});\nconst { svg } = await mermaid.render('d', `\n erDiagram\n USERS ||--o{ POSTS : writes\n POSTS ||--o{ COMMENTS : has\n`);\ndocument.getElementById('diagram').innerHTML = svg;\n</script>\n\n\nUse Mermaid for: ERDs, class diagrams, sequence diagrams, Gantt charts.\nUse hand-drawn SVG for: everything else (flowcharts, architecture,\nillustrative diagrams) — you get much better control.\n\n---\n\n## Part 5: Skill — Explanatory Writing Between Visuals\n\n### Narration Patterns\n\nThe Walk-Through: Point at parts of the visual and explain them.\n> "Starting at the top, the roof deck collects distributed loads across\n> its surface. These get channeled into the rafters below, which act\n> like one-way bridges..."\n\nThe "Why It Matters": Connect the visual to real consequences.\n> "This is why lower columns are always larger — they're carrying the\n> accumulated weight of every floor above."\n\nThe "Common Mistake": Anticipate misconceptions.\n> "One thing that trips people up: removing a single column doesn't just\n> lose that member — it breaks the entire load chain."\n\nThe "Go Deeper" Offer: End with expansion paths.\n> "Want me to show how lateral loads (wind, seismic) take a completely\n> different path?"\n\n### Tone Rules\n- Warm and direct. Not academic, not dumbed-down.\n- Use "you" and "we" freely.\n- Analogies and metaphors are powerful. Use them.\n- Short paragraphs (2-4 sentences). No walls of text.\n- Bold key terms on first introduction, then don't re-bold.\n- Never use bullet points for explanations. Prose only.\n- Ask at most one question per response.\n\n---\n\n## Part 6: Skill — Knowing What NOT to Visualize\n\nNot everything needs a diagram. Skip visuals when:\n\n- The answer is a single fact or number\n- The user is venting or emotional (empathy, not charts)\n- The topic is purely textual (writing, editing, drafting)\n- A code snippet is the answer (just show the code)\n- The user explicitly asked for brief/concise\n\n### The "Would They Screenshot This?" Test\n\nIf the user would likely screenshot or save the visual to reference\nlater, it was worth making. If not, just use text.\n\n---\n\n## Part 7: Putting It All Together\n\n### Example Response Structure (Complex Technical Question)\n\n\n[1-2 sentence hook validating the question]\n\n[Visual: SVG diagram or interactive widget]\n\n[Walk-through narration: 3-4 paragraphs explaining the visual,\n pointing at specific parts, noting key insights]\n\n[One \"go deeper\" offer with 2-3 specific directions]\n\n\n### Example Response Structure (Simple Question with Visual Aid)\n\n\n[Direct answer in 1-2 sentences]\n\n[Small supporting visual if it adds value]\n\n[One additional insight or context sentence]\n\n\n### Quality Checklist Before Responding\n\n- [ ] Did I pick the right format? (text vs SVG vs interactive vs chart)\n- [ ] Is the visual self-explanatory even without the narration?\n- [ ] Does the narration add value beyond what the visual shows?\n- [ ] Are colors meaningful, not decorative?\n- [ ] Does it work in dark mode?\n- [ ] Is the response concise? (Cut anything that doesn't teach)\n- [ ] Did I offer a clear next step?\n\n---\n\n## Appendix: Quick Reference\n\n| Concept Type | Best Format |\n|-------------------------|------------------------------|\n| How X works (physical) | Illustrative SVG diagram |\n| How X works (abstract) | Interactive HTML + SVG |\n| Process / workflow | SVG flowchart |\n| Architecture | SVG structural diagram |\n| Data relationships | Mermaid ERD |\n| Trends / comparisons | Chart.js or SVG bar chart |\n| Cyclic process | HTML step-through widget |\n| System states | Interactive widget + toggles |\n| Quick answer | Plain text |\n| Code solution | Code block / artifact |\n| Emotional support | Warm text only |\n\n\n============================================================\n# SKILL: svg-diagram-skill\n============================================================\n\n# SVG Diagram Generation Skill\n\nYou can generate rich, inline SVG diagrams to visually explain concepts. Use this skill whenever a visual would help the user understand a system, process, architecture, or mechanism better than text alone.\n\n---\n\n## When to Use\n\n- Explaining how something works (load paths, circuits, pipelines, algorithms)\n- Showing architecture or structure (system diagrams, component layouts)\n- Illustrating processes or flows (flowcharts, data flow, decision trees)\n- Building intuition for abstract concepts (attention mechanisms, gradient descent, recursion)\n\n## SVG Setup\n\nAlways use this template:\n\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 H\" xmlns=\"http://www.w3.org/2000/svg\">\n <defs>\n <marker id=\"arrow\" viewBox=\"0 0 10 10\" refX=\"8\" refY=\"5\"\n markerWidth=\"6\" markerHeight=\"6\" orient=\"auto-start-reverse\">\n <path d=\"M2 1L8 5L2 9\" fill=\"none\" stroke=\"context-stroke\"\n stroke-width=\"1.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"/>\n </marker>\n </defs>\n \n</svg>\n\n\n- Width is always 680px via viewBox. Set width=\"100%\" so it scales responsively.\n- H (height) = bottom-most element's y + height + 40px padding. Don't guess — compute it.\n- Safe content area: x=40 to x=640, y=40 to y=(H-40).\n- No wrapping divs, no <html>, <head>, <body>, or DOCTYPE.\n- Background is transparent — the host provides the background.\n\n---\n\n## Core Design Rules\n\n### Typography\n- Two sizes only: 14px for titles/labels, 12px for subtitles/descriptions.\n- Two weights only: 400 (regular), 500 (medium/bold). Never use 600 or 700.\n- Font: Use font-family=\"system-ui, -apple-system, sans-serif\" or inherit from host.\n- Always set text-anchor=\"middle\" and dominant-baseline=\"central\" for centered text in boxes.\n- Sentence case always. Never Title Case or ALL CAPS.\n\n### Text Width Estimation\nAt 14px, each character ≈ 8px wide. At 12px, each character ≈ 7px wide.\n- "Load Balancer" (13 chars) at 14px ≈ 104px → needs rect ≈ 140px wide (with padding).\n- Always compute: rect_width = max(title_chars × 8, subtitle_chars × 7) + 48px padding.\n\n### Colors (Light/Dark Mode Safe)\nUse these semantic color sets that work in both modes:\n\n\nTeal: fill=\"#E1F5EE\" stroke=\"#0F6E56\" text=\"#085041\" (dark: fill=\"#085041\" stroke=\"#5DCAA5\" text=\"#9FE1CB\")\nPurple: fill=\"#EEEDFE\" stroke=\"#534AB7\" text=\"#3C3489\" (dark: fill=\"#3C3489\" stroke=\"#AFA9EC\" text=\"#CECBF6\")\nCoral: fill=\"#FAECE7\" stroke=\"#993C1D\" text=\"#712B13\" (dark: fill=\"#712B13\" stroke=\"#F0997B\" text=\"#F5C4B3\")\nAmber: fill=\"#FAEEDA\" stroke=\"#854F0B\" text=\"#633806\" (dark: fill=\"#633806\" stroke=\"#EF9F27\" text=\"#FAC775\")\nBlue: fill=\"#E6F1FB\" stroke=\"#185FA5\" text=\"#0C447C\" (dark: fill=\"#0C447C\" stroke=\"#85B7EB\" text=\"#B5D4F4\")\nGray: fill=\"#F1EFE8\" stroke=\"#5F5E5A\" text=\"#444441\" (dark: fill=\"#444441\" stroke=\"#B4B2A9\" text=\"#D3D1C7\")\nRed: fill=\"#FCEBEB\" stroke=\"#A32D2D\" text=\"#791F1F\" (dark: fill=\"#791F1F\" stroke=\"#F09595\" text=\"#F7C1C1\")\nGreen: fill=\"#EAF3DE\" stroke=\"#3B6D11\" text=\"#27500A\" (dark: fill=\"#27500A\" stroke=\"#97C459\" text=\"#C0DD97\")\nPink: fill=\"#FBEAF0\" stroke=\"#993556\" text=\"#72243E\" (dark: fill=\"#72243E\" stroke=\"#ED93B1\" text=\"#F4C0D1\")\n\n\nColor meaning, not sequence: Don't rainbow-cycle. Use 2-3 colors per diagram. Map colors to categories or physical properties (warm = heat/energy, cool = calm/cold, gray = structural/neutral).\n\nIf you're rendering inside a system that supports CSS variables, prefer:\n- var(--color-text-primary) for primary text\n- var(--color-text-secondary) for muted text\n- var(--color-border-tertiary) for light borders\n\n### Shapes & Layout\n- Stroke width: 0.5px for borders, 1.5px for arrows/connectors.\n- Corner radius: rx=\"4\" for subtle rounding, rx=\"8\" for emphasized. rx=\"20\" for large containers.\n- Spacing: 60px minimum between boxes, 24px padding inside boxes, 12px text-to-edge clearance.\n- Single-line box: 44px tall. Two-line box: 56px tall.\n- Max 4-5 nodes per row at 680px width. If more, split into multiple diagrams.\n- All connectors need fill=\"none\" — SVG defaults fill to black, which turns paths into black blobs.\n\n---\n\n## Component Patterns\n\n### Single-Line Node\nsvg\n<g>\n <rect x=\"100\" y=\"20\" width=\"180\" height=\"44\" rx=\"8\"\n fill=\"#EEEDFE\" stroke=\"#534AB7\" stroke-width=\"0.5\"/>\n <text x=\"190\" y=\"42\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#3C3489\">Node title</text>\n</g>\n\n\n### Two-Line Node\nsvg\n<g>\n <rect x=\"100\" y=\"20\" width=\"200\" height=\"56\" rx=\"8\"\n fill=\"#E6F1FB\" stroke=\"#185FA5\" stroke-width=\"0.5\"/>\n <text x=\"200\" y=\"38\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#0C447C\">Title</text>\n <text x=\"200\" y=\"56\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#185FA5\">Short subtitle</text>\n</g>\n\n\n### Arrow Connector\nsvg\n<line x1=\"200\" y1=\"76\" x2=\"200\" y2=\"120\"\n stroke=\"#534AB7\" stroke-width=\"1.5\" marker-end=\"url(#arrow)\"/>\n\n\n### Dashed Flow Indicator\nsvg\n<line x1=\"200\" y1=\"76\" x2=\"200\" y2=\"120\"\n stroke=\"#534AB7\" stroke-width=\"1.5\" stroke-dasharray=\"4 3\"/>\n\n\n### Leader Line with Label (for annotations)\nsvg\n<line x1=\"440\" y1=\"100\" x2=\"500\" y2=\"130\"\n stroke=\"currentColor\" stroke-width=\"0.5\" stroke-dasharray=\"4 4\" opacity=\"0.5\"/>\n<circle cx=\"440\" cy=\"100\" r=\"2\" fill=\"currentColor\" opacity=\"0.5\"/>\n<text x=\"506\" y=\"134\" font-size=\"12\" fill=\"currentColor\" opacity=\"0.7\">Annotation text</text>\n\n\n### Large Container (for structural diagrams)\nsvg\n<rect x=\"80\" y=\"40\" width=\"520\" height=\"300\" rx=\"20\"\n fill=\"#E1F5EE\" stroke=\"#0F6E56\" stroke-width=\"0.5\"/>\n<text x=\"340\" y=\"68\" text-anchor=\"middle\"\n font-size=\"14\" font-weight=\"500\" fill=\"#085041\">Container name</text>\n\n\n---\n\n## Diagram Types & When to Use Each\n\n### 1. Flowchart\nWhen: Sequential processes, decision trees, pipelines.\nLayout: Top-to-bottom or left-to-right. Single direction only.\nRules:\n- Arrows must never cross unrelated boxes. Route around with L-bends if needed.\n- Keep all same-type boxes the same height.\n- Max 4-5 nodes per diagram. Break complex flows into multiple diagrams.\n\n### 2. Structural Diagram\nWhen: Containment matters — things inside other things (architecture, org charts, system components).\nLayout: Nested rectangles. Outer = container, inner = regions.\nRules:\n- Max 2-3 nesting levels.\n- 20px minimum padding inside every container.\n- Use different color ramps for parent vs child to show hierarchy.\n\n### 3. Illustrative Diagram\nWhen: Building intuition. "How does X actually work?"\nLayout: Freeform — follows the subject's natural geometry.\nRules:\n- Shapes can be freeform (paths, ellipses, polygons), not just rects.\n- Color encodes intensity, not category (warm = active, cool = dormant).\n- Overlap shapes for depth, but never let strokes cross text.\n- Labels go in margins with leader lines pointing to the relevant part.\n\n---\n\n## Critical Checks Before Finalizing\n\n1. ViewBox height: Find your lowest element (max y + height). Set H = that + 40px.\n2. No content past x=640 or below y=(H-40).\n3. Text fits in boxes: (char_count × 8) + 48 < rect_width for 14px text.\n4. No arrows through boxes: Trace every line's path — if it crosses a rect, reroute.\n5. All <path> connectors have fill=\"none\".\n6. All text has appropriate fill color — never rely on inheritance (SVG defaults to black).\n7. Colors work in dark mode: If using hardcoded colors, provide both light and dark variants. If using CSS variables, you're fine.\n\n---\n\n## Multi-Diagram Approach\n\nFor complex topics, use multiple smaller SVGs instead of one dense one:\n- Each SVG should have 3-5 nodes max.\n- Write explanatory text between diagrams.\n- First diagram = overview, subsequent = zoom into subsections.\n- Never promise diagrams you don't deliver.\n\n---\n\n## Example: Simple 3-Step Flow\n\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 260\" xmlns=\"http://www.w3.org/2000/svg\">\n <defs>\n <marker id=\"arrow\" viewBox=\"0 0 10 10\" refX=\"8\" refY=\"5\"\n markerWidth=\"6\" markerHeight=\"6\" orient=\"auto-start-reverse\">\n <path d=\"M2 1L8 5L2 9\" fill=\"none\" stroke=\"context-stroke\"\n stroke-width=\"1.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"/>\n </marker>\n </defs>\n\n \n <rect x=\"230\" y=\"20\" width=\"220\" height=\"56\" rx=\"8\"\n fill=\"#E1F5EE\" stroke=\"#0F6E56\" stroke-width=\"0.5\"/>\n <text x=\"340\" y=\"38\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#085041\">User request</text>\n <text x=\"340\" y=\"56\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#0F6E56\">HTTP POST /api/data</text>\n\n \n <line x1=\"340\" y1=\"76\" x2=\"340\" y2=\"100\" stroke=\"#534AB7\"\n stroke-width=\"1.5\" marker-end=\"url(#arrow)\"/>\n\n \n <rect x=\"230\" y=\"106\" width=\"220\" height=\"56\" rx=\"8\"\n fill=\"#EEEDFE\" stroke=\"#534AB7\" stroke-width=\"0.5\"/>\n <text x=\"340\" y=\"124\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#3C3489\">Server processing</text>\n <text x=\"340\" y=\"142\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#534AB7\">Validate and transform</text>\n\n \n <line x1=\"340\" y1=\"162\" x2=\"340\" y2=\"186\" stroke=\"#854F0B\"\n stroke-width=\"1.5\" marker-end=\"url(#arrow)\"/>\n\n \n <rect x=\"230\" y=\"192\" width=\"220\" height=\"56\" rx=\"8\"\n fill=\"#FAEEDA\" stroke=\"#854F0B\" stroke-width=\"0.5\"/>\n <text x=\"340\" y=\"210\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#633806\">Database write</text>\n <text x=\"340\" y=\"228\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#854F0B\">INSERT into table</text>\n</svg>\n\n\n---\n\n## Tips for Great Diagrams\n\n- Less is more: A clean 4-node diagram teaches better than a cramped 12-node one.\n- Color = meaning: Warm colors for active/hot/important, cool for passive/cold/secondary, gray for structural.\n- Streaming effect: Since SVGs render top-to-bottom as tokens arrive, structure your elements top-down for a natural build-up animation.\n- Annotations on the side: Put explanatory labels in the right margin (x > 560) with leader lines pointing to the relevant element.\n- Consistent heights: All boxes of the same type should be the same height.\n- Whitespace is your friend: Don't fill every pixel. Breathing room makes diagrams readable.\n\n ","additional_kwargs":{},"response_metadata":{},"type":"system","name":null,"id":null},{"content":"Create a 3D animation of a sphere turning into an icosahedron when the mouse is on it and back to a sphere when it's not on the icosahedron, make it cool.","additional_kwargs":{"type":"human"},"response_metadata":{},"type":"human","name":null,"id":"359afb39-50a7-44d5-8bf4-824fb6e44258"},{"content":"html\n<div id=\"scene-container\" style=\"width:100%; height:400px; position:relative;\">\n <script src=\"https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js\"></script>\n <script>\n // Initialize scene\n const container = document.getElementById('scene-container');\n const scene = new THREE.Scene();\n const camera = new THREE.PerspectiveCamera(75, container.clientWidth / container.clientHeight, 0.1, 1000);\n camera.position.z = 5;\n\n const renderer = new THREE.WebGLRenderer({ antialias: true, alpha: true });\n renderer.setSize(container.clientWidth, container.clientHeight);\n container.appendChild(renderer.domElement);\n\n // Detect color scheme\n const isDark = window.matchMedia('(prefers-color-scheme: dark)').matches;\n scene.background = new THREE.Color(isDark ? 0x111111 : 0xffffff);\n\n // Create icosahedron base geometry (detail level 3)\n const baseGeometry = new THREE.IcosahedronGeometry(1, 3);\n const originalVertices = baseGeometry.attributes.position.array.slice();\n const normalizedVertices = originalVertices.slice();\n\n // Normalize vertices to create sphere\n for (let i = 0; i < normalizedVertices.length; i += 3) {\n const x = normalizedVertices[i];\n const y = normalizedVertices[i + 1];\n const z = normalizedVertices[i + 2];\n const len = Math.sqrt(x * x + y * y + z * z);\n normalizedVertices[i] = x / len;\n normalizedVertices[i + 1] = y / len;\n normalizedVertices[i + 2] = z / len;\n }\n\n // Set base geometry to sphere (normalized vertices)\n baseGeometry.setAttribute('position', new THREE.Float32BufferAttribute(normalizedVertices, 3));\n baseGeometry.morphAttributes.position = [new THREE.Float32BufferAttribute(originalVertices, 3)];\n\n // Material with morphing support\n const material = new THREE.MeshStandardMaterial({\n color: isDark ? 0xbb86fc : 0x6200ea,\n wireframe: false,\n flatShading: true,\n morphTargets: true\n });\n\n const mesh = new THREE.Mesh(baseGeometry, material);\n scene.add(mesh);\n\n // Lighting\n const ambientLight = new THREE.AmbientLight(0xffffff, 0.5);\n scene.add(ambientLight);\n const directionalLight = new THREE.DirectionalLight(0xffffff, 0.8);\n directionalLight.position.set(1, 1, 1);\n scene.add(directionalLight);\n\n // Animation variables\n let targetInfluence = 0;\n let currentInfluence = 0;\n const speed = 0.05;\n let mouseOver = false;\n\n // Raycaster for mouse interaction\n const raycaster = new THREE.Raycaster();\n const mouse = new THREE.Vector2();\n\n function onMouseMove(event) {\n mouse.x = (event.clientX / container.clientWidth) * 2 - 1;\n mouse.y = -(event.clientY / container.clientHeight) * 2 + 1;\n }\n\n function checkIntersection() {\n raycaster.setFromCamera(mouse, camera);\n const intersects = raycaster.intersectObject(mesh);\n mouseOver = intersects.length > 0;\n targetInfluence = mouseOver ? 1 : 0;\n }\n\n container.addEventListener('mousemove', onMouseMove);\n\n // Animation loop\n function animate() {\n requestAnimationFrame(animate);\n \n // Update morph influence\n currentInfluence += (targetInfluence - currentInfluence) * speed;\n mesh.morphTargetInfluences[0] = currentInfluence;\n \n // Rotate mesh\n mesh.rotation.x += 0.005;\n mesh.rotation.y += 0.005;\n \n checkIntersection();\n renderer.render(scene, camera);\n }\n\n // Handle window resize\n function onWindowResize() {\n camera.aspect = container.clientWidth / container.clientHeight;\n camera.updateProjectionMatrix();\n renderer.setSize(container.clientWidth, container.clientHeight);\n }\n window.addEventListener('resize', onWindowResize);\n\n animate();\n </script>\n</div>\n","additional_kwargs":{"invalid_tool_calls":[],"usage_metadata":null},"response_metadata":{"finish_reason":"stop","model_name":"gausso-think","model_provider":"openai"},"type":"ai","name":null,"id":"lc_run--019cfea4-6c24-7202-8d80-f008019847c3","tool_calls":[],"invalid_tool_calls":[],"usage_metadata":null},{"content":"I want to understand the difference between BFS and DFS.

A sphere smoothly morphs into an icosahedron when hovered\n2. Returns to sphere form when the mouse moves away\n3. Automatically rotates to showcase the transformation\n4.

When a user asks you to visualize, explain visually,\n diagram, or illustrate something, you MUST use the widgetRenderer component\n instead of plain text.\n\n The widgetRenderer component accepts three parameters:\n - title: A short title for the visualization\n - description: A one-sentence description of what the visualization shows\n - html: A self-contained HTML fragment with inline <style> and <script> tags\n\n The HTML you produce will be rendered inside a sandboxed iframe that already has:\n - CSS variables for light/dark mode theming (use var(--color-text-primary), etc.)\n - Pre-styled form elements (buttons, inputs, sliders look native automatically)\n - Pre-built SVG CSS classes for color ramps (.c-purple, .c-teal, .c-blue, etc.)\n\n Follow the skills below for how to produce high-quality visuals:\n\n \n\n============================================================\n# SKILL: agent-skills-vol2\n============================================================\n\n# Agent Visualization Skills — Volume 2: Advanced Techniques\n\nPrerequisite: Volume 1 (SVG diagrams, basic interactive widgets, Chart.js, Mermaid).\nThis volume covers: UI mockups, dashboards, advanced interactivity, generative art,\nsimulations, math visualizations, and the design system that ties everything together.\n\n---\n\n## Part 1: The Design System\n\nEvery visual you produce should feel native to the host interface — not like\nan embedded iframe from somewhere else. These rules apply to ALL output types.\n\n### CSS Variables (Auto Light/Dark Mode)\n\ncss\n/* Backgrounds */\n--color-background-primary /* white in light, near-black in dark */\n--color-background-secondary /* surface cards */\n--color-background-tertiary /* page background */\n--color-background-info /* blue tint */\n--color-background-danger /* red tint */\n--color-background-success /* green tint */\n--color-background-warning /* amber tint */\n\n/* Text */\n--color-text-primary /* main text */\n--color-text-secondary /* muted / labels */\n--color-text-tertiary /* hints / placeholders */\n--color-text-info / -danger / -success / -warning\n\n/* Borders */\n--color-border-tertiary /* default: 0.15 alpha */\n--color-border-secondary /* hover: 0.3 alpha */\n--color-border-primary /* active: 0.4 alpha */\n\n/* Typography */\n--font-sans /* default body font */\n--font-serif /* editorial / blockquote only */\n--font-mono /* code */\n\n/* Layout */\n--border-radius-md /* 8px - most elements */\n--border-radius-lg /* 12px - cards */\n--border-radius-xl /* 16px - large containers */\n\n\nCritical rule: Never hardcode colors like #333 or #fff in HTML.\nThey break in the opposite mode. Always use CSS variables.\n\n### Typography Rules\n- h1 = 22px, h2 = 18px, h3 = 16px — all font-weight: 500\n- Body = 16px, weight 400, line-height: 1.7\n- Only two weights: 400 (regular) and 500 (medium). Never 600 or 700.\n- Sentence case everywhere. Never Title Case or ALL CAPS.\n- No mid-sentence bolding. Use code style for entity/class/function names.\n- No font-size below 11px anywhere.\n\n### Component Tokens\n- Borders: 0.5px solid var(--color-border-tertiary)\n- Cards: background: var(--color-background-primary),\n border: 0.5px solid var(--color-border-tertiary),\n border-radius: var(--border-radius-lg), padding: 1rem 1.25rem\n- No gradients, drop shadows, blur, glow, or neon effects\n- No emoji — use CSS shapes or SVG paths for icons\n- Background of outer container is always transparent\n\n### Number Formatting\nAlways round displayed numbers. JavaScript float math leaks artifacts:\n0.1 + 0.2 = 0.30000000000000004. Every number on screen must go through\nMath.round(), .toFixed(n), or Intl.NumberFormat.\n\n---\n\n## Part 2: UI Mockups\n\nFor when the user asks you to design or prototype a UI.\n\n### When to Use\n- "Design a settings page for..."\n- "Mock up a dashboard"\n- "What should this form look like?"\n- "Show me a card layout for..."\n- Prototyping before building\n\n### Presentation Rules\n\nContained mockups (mobile screens, modals, chat threads, single cards):\nWrap in a background surface so they don't float naked:\nhtml\n<div style=\"background: var(--color-background-secondary);\n border-radius: var(--border-radius-lg);\n padding: 2rem; display: flex; justify-content: center;\">\n \n</div>\n\n\nFull-width mockups (dashboards, settings pages, data tables):\nNo wrapper needed — they naturally fill the viewport.\n\n### Metric Cards (for dashboards)\nhtml\n<div style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(160px, 1fr));\n gap: 12px; margin-bottom: 1.5rem;\">\n\n <div style=\"background: var(--color-background-secondary);\n border-radius: var(--border-radius-md); padding: 1rem;\">\n <div style=\"font-size: 13px; color: var(--color-text-secondary);\n margin-bottom: 4px;\">Total revenue</div>\n <div style=\"font-size: 24px; font-weight: 500;\">$142,800</div>\n </div>\n\n <div style=\"background: var(--color-background-secondary);\n border-radius: var(--border-radius-md); padding: 1rem;\">\n <div style=\"font-size: 13px; color: var(--color-text-secondary);\n margin-bottom: 4px;\">Active users</div>\n <div style=\"font-size: 24px; font-weight: 500;\">8,421</div>\n </div>\n\n</div>\n\n\n### Contact / Data Record Card\nhtml\n<div style=\"background: var(--color-background-primary);\n border-radius: var(--border-radius-lg);\n border: 0.5px solid var(--color-border-tertiary);\n padding: 1rem 1.25rem;\">\n\n <div style=\"display: flex; align-items: center; gap: 12px;\n margin-bottom: 16px;\">\n \n <div style=\"width: 44px; height: 44px; border-radius: 50%;\n background: var(--color-background-info);\n display: flex; align-items: center; justify-content: center;\n font-weight: 500; font-size: 14px;\n color: var(--color-text-info);\">JD</div>\n <div>\n <p style=\"font-weight: 500; font-size: 15px; margin: 0;\">Jane Doe</p>\n <p style=\"font-size: 13px; color: var(--color-text-secondary);\n margin: 0;\">Lead Engineer</p>\n </div>\n </div>\n\n <div style=\"border-top: 0.5px solid var(--color-border-tertiary);\n padding-top: 12px;\">\n <table style=\"width: 100%; font-size: 13px;\">\n <tr>\n <td style=\"color: var(--color-text-secondary); padding: 4px 0;\">\n Email</td>\n <td style=\"text-align: right; padding: 4px 0;\n color: var(--color-text-info);\">jane@company.com</td>\n </tr>\n </table>\n </div>\n</div>\n\n\n### Badges and Status Pills\nhtml\n\n<span style=\"display: inline-block; font-size: 12px; padding: 4px 12px;\n border-radius: var(--border-radius-md);\n background: var(--color-background-success);\n color: var(--color-text-success);\">Active</span>\n\n\n<div style=\"border: 2px solid var(--color-border-info);\n border-radius: var(--border-radius-lg);\n padding: 1rem 1.25rem;\">\n <span style=\"font-size: 12px; padding: 4px 12px;\n border-radius: var(--border-radius-md);\n background: var(--color-background-info);\n color: var(--color-text-info);\">Most popular</span>\n</div>\n\n\n### Form Elements\nInputs, selects, textareas, buttons, and range sliders are pre-styled\nin the host environment.

(Content visible)\n- [ ] Do all interactive controls have event handlers?\n- [ ] Are all displayed numbers rounded properly?\n- [ ] Does the canvas/SVG fit within the container width?\n\n### Visual\n- [ ] Dark mode test: would every element be readable on near-black?\n- [ ] No hardcoded text colors in HTML (use CSS variables)\n- [ ] No gradients, shadows, blur, or glow\n- [ ] Borders are 0.5px (except 2px for featured item accent)\n- [ ] Font weights are only 400 or 500\n- [ ] All text is sentence case\n\n### Content\n- [ ] Explanatory text is in the response, not inside the widget\n- [ ] No titles or headings embedded in the HTML output\n- [ ] Visual is self-explanatory without reading the narration\n- [ ] Narration adds value beyond what the visual shows\n- [ ] Offered a clear "go deeper" path\n\n### Accessibility\n- [ ] @media (prefers-reduced-motion: reduce) for all animations\n- [ ] Text contrast is sufficient (dark text on light fills, vice versa)\n- [ ] Interactive elements are large enough to click (min 44px touch target)\n- [ ] No information conveyed by color alone\n\n---\n\n## Part 9: Decision Matrix — Picking the Right Visual\n\n| User asks about... | Output type | Technology |\n|-----------------------------|--------------------------|---------------------|\n| How X works (physical) | Illustrative diagram | SVG |\n| How X works (abstract) | Interactive explainer | HTML + inline SVG |\n| Process / steps | Flowchart | SVG |\n| Architecture / containment | Structural diagram | SVG |\n| Database schema / ERD | Relationship diagram | Mermaid |\n| Trends over time | Line chart | Chart.js |\n| Category comparison | Bar chart | Chart.js |\n| Part of whole | Doughnut chart | Chart.js |\n| KPIs / metrics | Dashboard | HTML metric cards |\n| Design a UI | Mockup | HTML |\n| Choose between options | Comparison cards | HTML grid |\n| Cyclic process | Step-through | HTML stepper |\n| Physics / math | Simulation | Canvas + JS |\n| Function / equation | Plotter | SVG + JS |\n| Data exploration | Sortable table | HTML + JS |\n| Creative / decorative | Art / illustration | SVG |\n| 3D visualization | 3D scene | Three.js |\n| Music / audio | Synthesizer | Tone.js |\n| Network / graph | Force layout | D3.js |\n| Quick factual answer | Plain text | None |\n| Code solution | Code block | None |\n| Emotional support | Warm text | None |\n\n\n============================================================\n# SKILL: master-agent-playbook\n============================================================\n\n# Master Agent Playbook: Making AI Responses Extraordinary\n\nThis playbook teaches an AI coding agent how to go beyond plain text and deliver\nresponses that are visual, interactive, and deeply educational. It covers the\nphilosophy, decision-making, and technical skills needed.\n\n---\n\n## Part 1: The Core Philosophy\n\n### Think Like a Teacher, Not a Search Engine\n\nBad: "A load path is the route that forces take through a structure to the ground."\nGood: [draws an interactive building cross-section with loads flowing downward]\n\nThe principle: Show, don't just tell. Before writing any response, ask:\n- Would a diagram make this click faster than a paragraph?\n- Would an interactive widget let the user explore the concept themselves?\n- Would a worked example teach better than a definition?\n\n### The Response Decision Tree\n\n\nUser asks a question\n │\n ├─ Is it a quick factual answer? → Answer in 1-2 sentences.\n │\n ├─ Is it conceptual / \"how does X work\"?\n │ ├─ Is it spatial or visual? → SVG illustrative diagram\n │ ├─ Is it a process/flow? → SVG flowchart or HTML stepper\n │ ├─ Is it data-driven? → Interactive chart (Chart.js / Recharts)\n │ └─ Is it abstract but explorable? → Interactive HTML widget with controls\n │\n ├─ Is it \"build me X\"? → Working code artifact, fully functional\n │\n ├─ Is it a comparison? → Side-by-side table or comparative visual\n │\n └─ Is it emotional/personal? → Warm text response. No visuals needed.\n\n\n### The 3-Layer Response Pattern\n\nGreat responses layer information:\n\n1. Hook (1-2 sentences): Validate the question, set context.\n2. Visual (diagram/widget): The core explanation, rendered visually.\n3. Narration (2-4 paragraphs): Walk through the visual, add nuance,\n connect to what the user already knows. Offer to go deeper.\n\nNever dump a visual without narration. Never narrate without visuals\nwhen visuals would help.\n\n---\n\n## Part 2: Skill — Interactive HTML Widgets\n\nFor concepts that benefit from user exploration. More powerful than\nstatic SVGs — users can manipulate parameters and see results.\n\n### When to Use\n- The concept has a variable the user could tweak (temperature, rate, count)\n- The system has states the user could toggle (on/off, mode A/B)\n- The explanation benefits from stepping through stages\n- Data exploration or filtering is involved\n\n### Template: Interactive Widget with Controls\n\nhtml\n<style>\n .controls {\n display: flex;\n align-items: center;\n gap: 16px;\n margin: 12px 0;\n font-size: 13px;\n color: var(--color-text-secondary, #666);\n }\n .controls label {\n display: flex;\n align-items: center;\n gap: 6px;\n }\n input[type=\"range\"] { flex: 1; }\n</style>\n\n\n<svg width=\"100%\" viewBox=\"0 0 680 400\" xmlns=\"http://www.w3.org/2000/svg\">\n \n <rect id=\"dynamic-element\" x=\"100\" y=\"100\" width=\"200\" height=\"50\"\n fill=\"#E6F1FB\" stroke=\"#185FA5\" stroke-width=\"0.5\" rx=\"8\"/>\n</svg>\n\n\n<div class=\"controls\">\n <label>\n <span>Parameter</span>\n <input type=\"range\" id=\"param-slider\" min=\"0\" max=\"100\" value=\"50\"\n oninput=\"updateParam(this.value)\">\n <span id=\"param-label\">50</span>\n </label>\n</div>\n\n<script>\nfunction updateParam(value) {\n document.getElementById('param-label').textContent = value;\n // Modify SVG elements based on value\n const el = document.getElementById('dynamic-element');\n el.setAttribute('width', 100 + value * 2);\n}\n</script>\n\n\n### Template: Step-Through Explainer\n\nFor cyclic or staged processes (event loops, biological cycles, pipelines).\n\nhtml\n<style>\n .step-nav {\n display: flex;\n align-items: center;\n gap: 12px;\n margin: 12px 0;\n font-size: 13px;\n }\n .step-nav button {\n padding: 6px 16px;\n border: 1px solid var(--color-border-tertiary, #ddd);\n border-radius: 8px;\n background: var(--color-background-secondary, #f5f5f5);\n color: var(--color-text-primary, #333);\n cursor: pointer;\n font-size: 13px;\n }\n .step-nav button:hover {\n background: var(--color-background-tertiary, #eee);\n }\n .dot { width: 8px; height: 8px; border-radius: 50%;\n background: var(--color-border-tertiary, #ccc);\n transition: background 0.2s; }\n .dot.active { background: var(--color-text-info, #185FA5); }\n .step-content { min-height: 300px; }\n</style>\n\n<div class=\"step-content\" id=\"step-display\">\n \n</div>\n\n<div class=\"step-nav\">\n <button onclick=\"prevStep()\">Previous</button>\n <div id=\"dots\" style=\"display:flex;gap:6px\"></div>\n <button onclick=\"nextStep()\">Next</button>\n <span id=\"step-label\" style=\"margin-left:auto;\n color:var(--color-text-secondary,#888)\">Step 1 of 4</span>\n</div>\n\n<script>\nconst steps = [\n { title: \"Step 1\", svg: `<svg>...</svg>`, desc: \"What happens first\" },\n { title: \"Step 2\", svg: `<svg>...</svg>`, desc: \"Then this\" },\n // ...\n];\nlet current = 0;\n\nfunction render() {\n document.getElementById('step-display').innerHTML = steps[current].svg;\n document.getElementById('step-label').textContent =\n `Step ${current + 1} of ${steps.length}`;\n document.querySelectorAll('.dot').forEach((d, i) =>\n d.classList.toggle('active', i === current));\n}\n\nfunction nextStep() { current = (current + 1) % steps.length; render(); }\nfunction prevStep() { current = (current - 1 + steps.length) % steps.length; render(); }\n\n// Build dots\nconst dotsEl = document.getElementById('dots');\nsteps.forEach(() => {\n const d = document.createElement('div');\n d.className = 'dot';\n dotsEl.appendChild(d);\n});\nrender();\n</script>\n\n\n### CSS Animation Patterns (for live diagrams)\n\ncss\n/* Flowing particles along a path */\n@keyframes flow {\n to { stroke-dashoffset: -20; }\n}\n.flowing {\n stroke-dasharray: 5 5;\n animation: flow 1.6s linear infinite;\n}\n\n/* Pulsing glow for active elements */\n@keyframes pulse {\n 0%, 100% { opacity: 0.3; }\n 50% { opacity: 0.7; }\n}\n.pulsing { animation: pulse 2s ease-in-out infinite; }\n\n/* Flickering (for flames, sparks) */\n@keyframes flicker {\n 0%, 100% { opacity: 1; }\n 50% { opacity: 0.8; }\n}\n\n/* Always respect reduced motion preferences */\n@media (prefers-reduced-motion: reduce) {\n *, *::before, *::after {\n animation-duration: 0.01ms !important;\n animation-iteration-count: 1 !important;\n }\n}\n\n\n---\n\n## Part 3: Skill — Data Visualization\n\n### When to Use\n- Comparing quantities\n- Showing trends over time\n- Displaying distributions or proportions\n- Making data explorable\n\n### Approach: Inline SVG Charts (No Dependencies)\n\nFor simple charts, hand-draw in SVG. No library needed.\n\nsvg\n\n<svg width=\"100%\" viewBox=\"0 0 680 300\">\n \n <line x1=\"80\" y1=\"40\" x2=\"80\" y2=\"250\" stroke=\"currentColor\"\n stroke-width=\"0.5\" opacity=\"0.3\"/>\n \n <line x1=\"80\" y1=\"250\" x2=\"620\" y2=\"250\" stroke=\"currentColor\"\n stroke-width=\"0.5\" opacity=\"0.3\"/>\n\n \n <rect x=\"120\" y=\"100\" width=\"60\" height=\"150\" rx=\"4\"\n fill=\"#EEEDFE\" stroke=\"#534AB7\" stroke-width=\"0.5\"/>\n <text x=\"150\" y=\"270\" text-anchor=\"middle\" font-size=\"12\"\n fill=\"currentColor\" opacity=\"0.7\">Q1</text>\n <text x=\"150\" y=\"92\" text-anchor=\"middle\" font-size=\"12\"\n fill=\"#3C3489\">$42k</text>\n \n</svg>\n\n\n### Approach: Chart.js (For Complex/Interactive Charts)\n\nWhen you need tooltips, responsive legends, animations:\n\nhtml\n<canvas id=\"myChart\" style=\"width:100%;max-height:400px\"></canvas>\n<script src=\"https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.4.1/chart.umd.js\"></script>\n<script>\nconst isDark = window.matchMedia('(prefers-color-scheme: dark)').matches;\nconst textColor = isDark ?

These get channeled into the rafters below, which act\n> like one-way bridges..."\n\nThe "Why It Matters": Connect the visual to real consequences.\n> "This is why lower columns are always larger — they're carrying the\n> accumulated weight of every floor above."\n\nThe "Common Mistake": Anticipate misconceptions.\n> "One thing that trips people up: removing a single column doesn't just\n> lose that member — it breaks the entire load chain."\n\nThe "Go Deeper" Offer: End with expansion paths.\n> "Want me to show how lateral loads (wind, seismic) take a completely\n> different path?"\n\n### Tone Rules\n- Warm and direct. Not academic, not dumbed-down.\n- Use "you" and "we" freely.\n- Analogies and metaphors are powerful. Use them.\n- Short paragraphs (2-4 sentences). No walls of text.\n- Bold key terms on first introduction, then don't re-bold.\n- Never use bullet points for explanations. Prose only.\n- Ask at most one question per response.\n\n---\n\n## Part 6: Skill — Knowing What NOT to Visualize\n\nNot everything needs a diagram. Skip visuals when:\n\n- The answer is a single fact or number\n- The user is venting or emotional (empathy, not charts)\n- The topic is purely textual (writing, editing, drafting)\n- A code snippet is the answer (just show the code)\n- The user explicitly asked for brief/concise\n\n### The "Would They Screenshot This?"

Use this skill whenever a visual would help the user understand a system, process, architecture, or mechanism better than text alone.\n\n---\n\n## When to Use\n\n- Explaining how something works (load paths, circuits, pipelines, algorithms)\n- Showing architecture or structure (system diagrams, component layouts)\n- Illustrating processes or flows (flowcharts, data flow, decision trees)\n- Building intuition for abstract concepts (attention mechanisms, gradient descent, recursion)\n\n## SVG Setup\n\nAlways use this template:\n\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 H\" xmlns=\"http://www.w3.org/2000/svg\">\n <defs>\n <marker id=\"arrow\" viewBox=\"0 0 10 10\" refX=\"8\" refY=\"5\"\n markerWidth=\"6\" markerHeight=\"6\" orient=\"auto-start-reverse\">\n <path d=\"M2 1L8 5L2 9\" fill=\"none\" stroke=\"context-stroke\"\n stroke-width=\"1.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"/>\n </marker>\n </defs>\n \n</svg>\n\n\n- Width is always 680px via viewBox. Set width=\"100%\" so it scales responsively.\n- H (height) = bottom-most element's y + height + 40px padding. Don't guess — compute it.\n- Safe content area: x=40 to x=640, y=40 to y=(H-40).\n- No wrapping divs, no <html>, <head>, <body>, or DOCTYPE.\n- Background is transparent — the host provides the background.\n\n---\n\n## Core Design Rules\n\n### Typography\n- Two sizes only: 14px for titles/labels, 12px for subtitles/descriptions.\n- Two weights only: 400 (regular), 500 (medium/bold). Never use 600 or 700.\n- Font: Use font-family=\"system-ui, -apple-system, sans-serif\" or inherit from host.\n- Always set text-anchor=\"middle\" and dominant-baseline=\"central\" for centered text in boxes.\n- Sentence case always. Never Title Case or ALL CAPS.\n\n### Text Width Estimation\nAt 14px, each character ≈ 8px wide. At 12px, each character ≈ 7px wide.\n- "Load Balancer" (13 chars) at 14px ≈ 104px → needs rect ≈ 140px wide (with padding).\n- Always compute: rect_width = max(title_chars × 8, subtitle_chars × 7) + 48px padding.\n\n### Colors (Light/Dark Mode Safe)\nUse these semantic color sets that work in both modes:\n\n\nTeal: fill=\"#E1F5EE\" stroke=\"#0F6E56\" text=\"#085041\" (dark: fill=\"#085041\" stroke=\"#5DCAA5\" text=\"#9FE1CB\")\nPurple: fill=\"#EEEDFE\" stroke=\"#534AB7\" text=\"#3C3489\" (dark: fill=\"#3C3489\" stroke=\"#AFA9EC\" text=\"#CECBF6\")\nCoral: fill=\"#FAECE7\" stroke=\"#993C1D\" text=\"#712B13\" (dark: fill=\"#712B13\" stroke=\"#F0997B\" text=\"#F5C4B3\")\nAmber: fill=\"#FAEEDA\" stroke=\"#854F0B\" text=\"#633806\" (dark: fill=\"#633806\" stroke=\"#EF9F27\" text=\"#FAC775\")\nBlue: fill=\"#E6F1FB\" stroke=\"#185FA5\" text=\"#0C447C\" (dark: fill=\"#0C447C\" stroke=\"#85B7EB\" text=\"#B5D4F4\")\nGray: fill=\"#F1EFE8\" stroke=\"#5F5E5A\" text=\"#444441\" (dark: fill=\"#444441\" stroke=\"#B4B2A9\" text=\"#D3D1C7\")\nRed: fill=\"#FCEBEB\" stroke=\"#A32D2D\" text=\"#791F1F\" (dark: fill=\"#791F1F\" stroke=\"#F09595\" text=\"#F7C1C1\")\nGreen: fill=\"#EAF3DE\" stroke=\"#3B6D11\" text=\"#27500A\" (dark: fill=\"#27500A\" stroke=\"#97C459\" text=\"#C0DD97\")\nPink: fill=\"#FBEAF0\" stroke=\"#993556\" text=\"#72243E\" (dark: fill=\"#72243E\" stroke=\"#ED93B1\" text=\"#F4C0D1\")\n\n\nColor meaning, not sequence: Don't rainbow-cycle. Use 2-3 colors per diagram. Map colors to categories or physical properties (warm = heat/energy, cool = calm/cold, gray = structural/neutral).\n\nIf you're rendering inside a system that supports CSS variables, prefer:\n- var(--color-text-primary) for primary text\n- var(--color-text-secondary) for muted text\n- var(--color-border-tertiary) for light borders\n\n### Shapes & Layout\n- Stroke width: 0.5px for borders, 1.5px for arrows/connectors.\n- Corner radius: rx=\"4\" for subtle rounding, rx=\"8\" for emphasized. rx=\"20\" for large containers.\n- Spacing: 60px minimum between boxes, 24px padding inside boxes, 12px text-to-edge clearance.\n- Single-line box: 44px tall. Two-line box: 56px tall.\n- Max 4-5 nodes per row at 680px width. If more, split into multiple diagrams.\n- All connectors need fill=\"none\" — SVG defaults fill to black, which turns paths into black blobs.\n\n---\n\n## Component Patterns\n\n### Single-Line Node\nsvg\n<g>\n <rect x=\"100\" y=\"20\" width=\"180\" height=\"44\" rx=\"8\"\n fill=\"#EEEDFE\" stroke=\"#534AB7\" stroke-width=\"0.5\"/>\n <text x=\"190\" y=\"42\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#3C3489\">Node title</text>\n</g>\n\n\n### Two-Line Node\nsvg\n<g>\n <rect x=\"100\" y=\"20\" width=\"200\" height=\"56\" rx=\"8\"\n fill=\"#E6F1FB\" stroke=\"#185FA5\" stroke-width=\"0.5\"/>\n <text x=\"200\" y=\"38\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#0C447C\">Title</text>\n <text x=\"200\" y=\"56\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#185FA5\">Short subtitle</text>\n</g>\n\n\n### Arrow Connector\nsvg\n<line x1=\"200\" y1=\"76\" x2=\"200\" y2=\"120\"\n stroke=\"#534AB7\" stroke-width=\"1.5\" marker-end=\"url(#arrow)\"/>\n\n\n### Dashed Flow Indicator\nsvg\n<line x1=\"200\" y1=\"76\" x2=\"200\" y2=\"120\"\n stroke=\"#534AB7\" stroke-width=\"1.5\" stroke-dasharray=\"4 3\"/>\n\n\n### Leader Line with Label (for annotations)\nsvg\n<line x1=\"440\" y1=\"100\" x2=\"500\" y2=\"130\"\n stroke=\"currentColor\" stroke-width=\"0.5\" stroke-dasharray=\"4 4\" opacity=\"0.5\"/>\n<circle cx=\"440\" cy=\"100\" r=\"2\" fill=\"currentColor\" opacity=\"0.5\"/>\n<text x=\"506\" y=\"134\" font-size=\"12\" fill=\"currentColor\" opacity=\"0.7\">Annotation text</text>\n\n\n### Large Container (for structural diagrams)\nsvg\n<rect x=\"80\" y=\"40\" width=\"520\" height=\"300\" rx=\"20\"\n fill=\"#E1F5EE\" stroke=\"#0F6E56\" stroke-width=\"0.5\"/>\n<text x=\"340\" y=\"68\" text-anchor=\"middle\"\n font-size=\"14\" font-weight=\"500\" fill=\"#085041\">Container name</text>\n\n\n---\n\n## Diagram Types & When to Use Each\n\n### 1. Flowchart\nWhen: Sequential processes, decision trees, pipelines.\nLayout: Top-to-bottom or left-to-right. Single direction only.\nRules:\n- Arrows must never cross unrelated boxes. Route around with L-bends if needed.\n- Keep all same-type boxes the same height.\n- Max 4-5 nodes per diagram. Break complex flows into multiple diagrams.\n\n### 2. Structural Diagram\nWhen: Containment matters — things inside other things (architecture, org charts, system components).\nLayout: Nested rectangles. Outer = container, inner = regions.\nRules:\n- Max 2-3 nesting levels.\n- 20px minimum padding inside every container.\n- Use different color ramps for parent vs child to show hierarchy.\n\n### 3. Illustrative Diagram\nWhen: Building intuition. "How does X actually work?"\nLayout: Freeform — follows the subject's natural geometry.\nRules:\n- Shapes can be freeform (paths, ellipses, polygons), not just rects.\n- Color encodes intensity, not category (warm = active, cool = dormant).\n- Overlap shapes for depth, but never let strokes cross text.\n- Labels go in margins with leader lines pointing to the relevant part.\n\n---\n\n## Critical Checks Before Finalizing\n\n1. ViewBox height: Find your lowest element (max y + height). Set H = that + 40px.\n2. No content past x=640 or below y=(H-40).\n3. Text fits in boxes: (char_count × 8) + 48 < rect_width for 14px text.\n4. No arrows through boxes: Trace every line's path — if it crosses a rect, reroute.\n5. All <path> connectors have fill=\"none\".\n6. All text has appropriate fill color — never rely on inheritance (SVG defaults to black).\n7. Colors work in dark mode: If using hardcoded colors, provide both light and dark variants. If using CSS variables, you're fine.\n\n---\n\n## Multi-Diagram Approach\n\nFor complex topics, use multiple smaller SVGs instead of one dense one:\n- Each SVG should have 3-5 nodes max.\n- Write explanatory text between diagrams.\n- First diagram = overview, subsequent = zoom into subsections.\n- Never promise diagrams you don't deliver.\n\n---\n\n## Example: Simple 3-Step Flow\n\nsvg\n<svg width=\"100%\" viewBox=\"0 0 680 260\" xmlns=\"http://www.w3.org/2000/svg\">\n <defs>\n <marker id=\"arrow\" viewBox=\"0 0 10 10\" refX=\"8\" refY=\"5\"\n markerWidth=\"6\" markerHeight=\"6\" orient=\"auto-start-reverse\">\n <path d=\"M2 1L8 5L2 9\" fill=\"none\" stroke=\"context-stroke\"\n stroke-width=\"1.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"/>\n </marker>\n </defs>\n\n \n <rect x=\"230\" y=\"20\" width=\"220\" height=\"56\" rx=\"8\"\n fill=\"#E1F5EE\" stroke=\"#0F6E56\" stroke-width=\"0.5\"/>\n <text x=\"340\" y=\"38\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#085041\">User request</text>\n <text x=\"340\" y=\"56\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#0F6E56\">HTTP POST /api/data</text>\n\n \n <line x1=\"340\" y1=\"76\" x2=\"340\" y2=\"100\" stroke=\"#534AB7\"\n stroke-width=\"1.5\" marker-end=\"url(#arrow)\"/>\n\n \n <rect x=\"230\" y=\"106\" width=\"220\" height=\"56\" rx=\"8\"\n fill=\"#EEEDFE\" stroke=\"#534AB7\" stroke-width=\"0.5\"/>\n <text x=\"340\" y=\"124\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#3C3489\">Server processing</text>\n <text x=\"340\" y=\"142\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#534AB7\">Validate and transform</text>\n\n \n <line x1=\"340\" y1=\"162\" x2=\"340\" y2=\"186\" stroke=\"#854F0B\"\n stroke-width=\"1.5\" marker-end=\"url(#arrow)\"/>\n\n \n <rect x=\"230\" y=\"192\" width=\"220\" height=\"56\" rx=\"8\"\n fill=\"#FAEEDA\" stroke=\"#854F0B\" stroke-width=\"0.5\"/>\n <text x=\"340\" y=\"210\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"14\" font-weight=\"500\" fill=\"#633806\">Database write</text>\n <text x=\"340\" y=\"228\" text-anchor=\"middle\" dominant-baseline=\"central\"\n font-size=\"12\" fill=\"#854F0B\">INSERT into table</text>\n</svg>\n\n\n---\n\n## Tips for Great Diagrams\n\n- Less is more: A clean 4-node diagram teaches better than a cramped 12-node one.\n- Color = meaning: Warm colors for active/hot/important, cool for passive/cold/secondary, gray for structural.\n- Streaming effect: Since SVGs render top-to-bottom as tokens arrive, structure your elements top-down for a natural build-up animation.\n- Annotations on the side: Put explanatory labels in the right margin (x > 560) with leader lines pointing to the relevant element.\n- Consistent heights: All boxes of the same type should be the same height.\n- Whitespace is your friend: Don't fill every pixel. Breathing room makes diagrams readable.\n\n ","additional_kwargs":{},"response_metadata":{},"type":"system","name":null,"id":null},{"content":"Create a 3D animation of a sphere turning into an icosahedron when the mouse is on it and back to a sphere when it's not on the icosahedron, make it cool.","additional_kwargs":{"type":"human"},"response_metadata":{},"type":"human","name":null,"id":"359afb39-50a7-44d5-8bf4-824fb6e44258"},{"content":"html\n<div id=\"scene-container\" style=\"width:100%; height:400px; position:relative;\">\n <script src=\"https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js\"></script>\n <script>\n // Initialize scene\n const container = document.getElementById('scene-container');\n const scene = new THREE.Scene();\n const camera = new THREE.PerspectiveCamera(75, container.clientWidth / container.clientHeight, 0.1, 1000);\n camera.position.z = 5;\n\n const renderer = new THREE.WebGLRenderer({ antialias: true, alpha: true });\n renderer.setSize(container.clientWidth, container.clientHeight);\n container.appendChild(renderer.domElement);\n\n // Detect color scheme\n const isDark = window.matchMedia('(prefers-color-scheme: dark)').matches;\n scene.background = new THREE.Color(isDark ? 0x111111 : 0xffffff);\n\n // Create icosahedron base geometry (detail level 3)\n const baseGeometry = new THREE.IcosahedronGeometry(1, 3);\n const originalVertices = baseGeometry.attributes.position.array.slice();\n const normalizedVertices = originalVertices.slice();\n\n // Normalize vertices to create sphere\n for (let i = 0; i < normalizedVertices.length; i += 3) {\n const x = normalizedVertices[i];\n const y = normalizedVertices[i + 1];\n const z = normalizedVertices[i + 2];\n const len = Math.sqrt(x * x + y * y + z * z);\n normalizedVertices[i] = x / len;\n normalizedVertices[i + 1] = y / len;\n normalizedVertices[i + 2] = z / len;\n }\n\n // Set base geometry to sphere (normalized vertices)\n baseGeometry.setAttribute('position', new THREE.Float32BufferAttribute(normalizedVertices, 3));\n baseGeometry.morphAttributes.position = [new THREE.Float32BufferAttribute(originalVertices, 3)];\n\n // Material with morphing support\n const material = new THREE.MeshStandardMaterial({\n color: isDark ? 0xbb86fc : 0x6200ea,\n wireframe: false,\n flatShading: true,\n morphTargets: true\n });\n\n const mesh = new THREE.Mesh(baseGeometry, material);\n scene.add(mesh);\n\n // Lighting\n const ambientLight = new THREE.AmbientLight(0xffffff, 0.5);\n scene.add(ambientLight);\n const directionalLight = new THREE.DirectionalLight(0xffffff, 0.8);\n directionalLight.position.set(1, 1, 1);\n scene.add(directionalLight);\n\n // Animation variables\n let targetInfluence = 0;\n let currentInfluence = 0;\n const speed = 0.05;\n let mouseOver = false;\n\n // Raycaster for mouse interaction\n const raycaster = new THREE.Raycaster();\n const mouse = new THREE.Vector2();\n\n function onMouseMove(event) {\n mouse.x = (event.clientX / container.clientWidth) * 2 - 1;\n mouse.y = -(event.clientY / container.clientHeight) * 2 + 1;\n }\n\n function checkIntersection() {\n raycaster.setFromCamera(mouse, camera);\n const intersects = raycaster.intersectObject(mesh);\n mouseOver = intersects.length > 0;\n targetInfluence = mouseOver ? 1 : 0;\n }\n\n container.addEventListener('mousemove', onMouseMove);\n\n // Animation loop\n function animate() {\n requestAnimationFrame(animate);\n \n // Update morph influence\n currentInfluence += (targetInfluence - currentInfluence) * speed;\n mesh.morphTargetInfluences[0] = currentInfluence;\n \n // Rotate mesh\n mesh.rotation.x += 0.005;\n mesh.rotation.y += 0.005;\n \n checkIntersection();\n renderer.render(scene, camera);\n }\n\n // Handle window resize\n function onWindowResize() {\n camera.aspect = container.clientWidth / container.clientHeight;\n camera.updateProjectionMatrix();\n renderer.setSize(container.clientWidth, container.clientHeight);\n }\n window.addEventListener('resize', onWindowResize);\n\n animate();\n </script>\n</div>\n","additional_kwargs":{"invalid_tool_calls":[],"usage_metadata":null},"response_metadata":{"finish_reason":"stop","model_name":"gausso-think","model_provider":"openai"},"type":"ai","name":null,"id":"lc_run--019cfea4-6c24-7202-8d80-f008019847c3","tool_calls":[],"invalid_tool_calls":[],"usage_metadata":null},{"content":"I want to understand the difference between BFS and DFS.
