Render SVG content to a PNG image so the AI can visually inspect the output. **When to use:** - render_svg already returns a preview image by default; call this tool to re-preview a stored artifact at a different width, or to preview SVG that did not come from render_svg - Stop iterating when the visual result matches the intent **Input:** pass EITHER artifact (id from render_svg, e.g. "art-1" — preferred, no SVG resend) OR content (raw SVG string). **Behavior:** - Returns a PNG image (base64) rendered from the SVG - Background is transparent by default - CSS animations and SMIL are rendered as a static snapshot (t=0) — motion is not captured **Width:** - Omit width to use the SVG's own declared width/viewBox - Pass width to scale the output (useful for small SVGs that need a larger preview)

Render animated SVG from JSON config. AI controls all design parameters. **Workflow:** render_svg returns a PNG preview of the result plus an artifact id — critique the image, revise the config, render again. Iterate at least 3 times before finalizing. The SVG text stays on the server: pass the artifact id to save (and to preview for a different width). **output options (response shape, not content):** {"svg":false,"preview":true,"previewWidth":800,"minify":false,"frames":4} — all optional. minify:true collapses whitespace in the stored/saved SVG. frames:N (2-10) replaces the static preview with one filmstrip image sampling the CSS animations at N times — use it to verify motion (rotation direction, timing, easing) since a single preview only shows t=0. SMIL is not sampled. **Element types:** rect, circle, ellipse, line, polyline, polygon, path, image, text, textPath, group, use, radial-group, arc-group, grid-group, scatter-group, path-group, parametric **Pattern groups** (use for repetitive designs): radial-group (circular: cx, cy, radius, count), arc-group (arc: cx, cy, radius, count, startAngle, endAngle), grid-group (matrix: cols, rows, colSpacing, rowSpacing), scatter-group (random: width, height, count, seed), path-group (along polyline: waypoints, count). Each takes ONE "child" element. The child is drawn at the local origin and, with rotateChildren true (the default), rotates so local +x points outward from the center: draw spokes, rays and petals long along the x axis, never the y axis, or they render as a chord ring. **Parametric curves** (fn field): rose, heart, lissajous, spiral, star, superformula, epitrochoid, hypotrochoid, wave. Size via "scale" field. Server computes coordinates. **defs:** gradients (linear/radial, SMIL animated stops), filters (presets: glow, neon, blur, drop-shadow, glitch, chromatic-aberration, noise, outline, inner-shadow, emboss + 5 more), clipPaths, masks, patterns (tile fills), markers (arrowheads: triangle, arrow, circle, square, diamond, bar; set markerStart/markerEnd:"id" on line/polyline/path, scales with strokeWidth). **Animations:** CSS @keyframes via animations array. Set cssClass on element matching animation name. For transforms add transformBox="fill-box" transformOrigin="center". SMIL via smilAnimations on elements (animate, animateTransform, animateMotion). **Design guide (what makes output look good):** Pick one spacing unit (e.g. 8) and use multiples of it for every gap and margin; keep content clear of the canvas edges by at least 5% of the smaller dimension (the bbox audit reports overflow in px). Use at most 3 font sizes per design with clear jumps (e.g. 12/16/24). Body-size text needs 4.5:1 contrast against its background, 3:1 from 24px up (the contrast audit checks plain hex pairs). Text ink boxes are measured after every render; escaping or overlapping text comes back as a named design note. Motion: ease-out for entrances, ease-in-out for back-and-forth loops, linear only for continuous rotation or travel; 0.8-3s durations read well for UI-scale loops. **Critical format rules:** - Gradient type must be "linearGradient" or "radialGradient" (not "linear"/"radial"). Each needs id, stops (array with offset 0-1, color). - Filter type must be "preset" with a "preset" field: {"type":"preset","id":"myGlow","preset":"glow","stdDeviation":8,"color":"#ff00ff"} - Keyframe offset: use "from"/"to" or percentage number 0-100 (not "0%"/"100%"). - Gradient stop and filter colors: hex only (#rrggbb or #rrggbbaa). Element fill/stroke accept '#rrggbb', 'none', or 'url(#id)' (hex is safest). - Every element needs "type" field. circle needs r, rect needs width+height, path needs d. **Field names that differ from raw SVG:** - text: string goes in "content" (not "text"): {"type":"text","x":100,"y":50,"content":"Hello","fontSize":24,"textAnchor":"middle"} - textPath: {"type":"textPath","pathId":"idFromDefsPaths","text":"..."} — here the field IS "text". - group: {"type":"group","children":[...]} — children are shapes/text/use only, no nested groups. - Pattern groups take ONE "child" element drawn at local origin (child uses cx=0/cy=0); set rotateChildren:false to keep text upright. **Output:** Pure SVG XML. No JavaScript. CSS @keyframes + SMIL only.

Save rendered content to disk. Format-aware: can save as text or render to raster image. IMPORTANT: Use this only AFTER iterating on the design with render_svg's preview images. Do not save on the first render. Preview and refine your work first. **Input:** pass EITHER artifact (id from render_svg, e.g. "art-1" — preferred, no SVG resend) OR content (raw string). **Format detection:** - 'auto' (default): infers format from file extension. .svg saves as text, .png renders to image. - 'svg': saves content as a UTF-8 text file - 'png': renders the content (assumed SVG) to a PNG image, then saves it If the file already exists, a numeric counter is appended before the extension to prevent overwriting: design.svg becomes design-1.svg, then design-2.svg. The actual saved path is returned in the response.
