Treat the output as a **static poster in a fixed, no-scroll frame** — not a live web page, and not interactive.\n\n## What triggers a render\n\n- A render only happens when you call **`fetch_val_endpoint`**. The `run: { kind: \"fetch_val_endpoint\" }` option on `update_file` / `replace_in_file` counts, because it calls the same thing.\n- `create_file`, `update_file`, `list_files`, etc. show a *file / diff* widget, **not** the rendered HTML. Don't expect them to preview a page.\n- `fetch_val_endpoint` also returns the response (status + headers + body) to you as text, so it doubles as your inspect/debug tool. The endpoint is public.\n\n## The frame (measured)\n\n- Fixed size **≈ 885 × 386 px** — wide and short, aspect ≈ 2.3:1. It can vary slightly with client width, so design with a little margin.\n- **No scroll.** The iframe is sized to the document's *content height* and then clipped inside the fixed frame. Anything past ~386px tall is **cut off at the bottom** — there is no scrollbar.\n- You don't control the frame height from inside it, so you can't vertically center to it. Top-aligned content with empty space below is fine; overflow is not.\n\n## Hard rules (break these and the render fails)\n\n- **Never use `height:100vh`, `height:100%` on html/body, or `position:fixed` for layout.** Because the iframe is content-sized, viewport-relative heights resolve to ~0 and the whole thing renders **blank**. Use **normal document flow** with `auto` / explicit `px` heights.\n- **It is not interactive.** Clicks do not toggle CSS `:checked`, fire handlers, or submit forms — a click appears to **open / navigate to the val** instead. So:\n - No tabs, accordions, modals, hover-to-reveal, or anything that needs a click or tap.\n - Don't rely on `\n```\n\nThen use Tailwind classes directly in JSX:\n\n```tsx\n

Hello

\n```\n\nAvoid inline `\n\n\n

\n \n

\n \n\n\n```\n\n**CRITICAL**: This is a single artifact. No external files, no imports (except p5.js CDN). Everything inline.\n\n**4. Implementation Details - BUILD THE SIDEBAR**\n\nThe sidebar structure:\n\n**1. Seed (FIXED)** - Always include exactly as shown:\n- Seed display\n- Prev/Next/Random/Jump buttons\n\n**2. Parameters (VARIABLE)** - Create controls for the art:\n```html\n

\n Parameter Name\n \n ...\n

\n```\nAdd as many control-group divs as there are parameters.\n\n**3. Colors (OPTIONAL/VARIABLE)** - Include if the art needs adjustable colors:\n- Add color pickers if users should control palette\n- Skip this section if the art uses fixed colors\n- Skip if the art is monochrome\n\n**4. Actions (FIXED)** - Always include exactly as shown:\n- Regenerate button\n- Reset button\n- Download PNG button\n\n**Requirements**:\n- Seed controls must work (prev/next/random/jump/display)\n- All parameters must have UI controls\n- Regenerate, Reset, Download buttons must work\n- Keep Anthropic branding (UI styling, not art colors)\n\n### USING THE ARTIFACT\n\nThe HTML artifact works immediately:\n1. **In claude.ai**: Displayed as an interactive artifact - runs instantly\n2. **As a file**: Save and open in any browser - no server needed\n3. **Sharing**: Send the HTML file - it's completely self-contained\n\n---\n\n## VARIATIONS & EXPLORATION\n\nThe artifact includes seed navigation by default (prev/next/random buttons), allowing users to explore variations without creating multiple files. If the user wants specific variations highlighted:\n\n- Include seed presets (buttons for \"Variation 1: Seed 42\", \"Variation 2: Seed 127\", etc.)\n- Add a \"Gallery Mode\" that shows thumbnails of multiple seeds side-by-side\n- All within the same single artifact\n\nThis is like creating a series of prints from the same plate - the algorithm is consistent, but each seed reveals different facets of its potential. The interactive nature means users discover their own favorites by exploring the seed space.\n\n---\n\n## THE CREATIVE PROCESS\n\n**User request** → **Algorithmic philosophy** → **Implementation**\n\nEach request is unique. The process involves:\n\n1. **Interpret the user's intent** - What aesthetic is being sought?\n2. **Create an algorithmic philosophy** (4-6 paragraphs) describing the computational approach\n3. **Implement it in code** - Build the algorithm that expresses this philosophy\n4. **Design appropriate parameters** - What should be tunable?\n5. **Build matching UI controls** - Sliders/inputs for those parameters\n\n**The constants**:\n- Anthropic branding (colors, fonts, layout)\n- Seed navigation (always present)\n- Self-contained HTML artifact\n\n**Everything else is variable**:\n- The algorithm itself\n- The parameters\n- The UI controls\n- The visual outcome\n\nTo achieve the best results, trust creativity and let the philosophy guide the implementation.\n\n---\n\n## RESOURCES\n\nThis skill includes helpful templates and documentation:\n\n- **templates/viewer.html**: REQUIRED STARTING POINT for all HTML artifacts.\n - This is the foundation - contains the exact structure and Anthropic branding\n - **Keep unchanged**: Layout structure, sidebar organization, Anthropic colors/fonts, seed controls, action buttons\n - **Replace**: The p5.js algorithm, parameter definitions, and UI controls in Parameters section\n - The extensive comments in the file mark exactly what to keep vs replace\n\n- **templates/generator_template.js**: Reference for p5.js best practices and code structure principles.\n - Shows how to organize parameters, use seeded randomness, structure classes\n - NOT a pattern menu - use these principles to build unique algorithms\n - Embed algorithms inline in the HTML artifact (don't create separate .js files)\n\n**Critical reminder**:\n- The **template is the STARTING POINT**, not inspiration\n- The **algorithm is where to create** something unique\n- Don't copy the flow field example - build what the philosophy demands\n- But DO keep the exact UI structure and Anthropic branding from the template",[],[167,975,1201,388],"algorithmic-art","043c08ea-2631-4f1e-b7ff-131a95ef7924",207,["D",1781279544411],[202],[167,975,1201],"50da6a59-8690-4e72-8c1c-de2b4f8ffc12",204,["D",1781279526503],[201,203,205,207,209,211,213,215,217,219,221,223,225,227,229,231,233],[167,975],["D",1779816059463],[200,235,244,252,261,263,272,274,276,288,297,299,318,320],[167],"8339cde9-ab09-41e2-9bf1-26f705c2a3a0","generate-missing-art.ts","58daf112-64f8-11f1-b95b-1607ee4eb77e",199,["D",1781279020552],"// Generate card art for every skill that has none cached (the cards that fall\n// back to the generic SVG placeholder).
