SVG Style Studio · /create-svg

Invocation. /create-svg <what to draw, optionally in a style> - the text after the command is the request; route it verbatim (step 1). Bare /create-svg with nothing after it → ask in one line what to draw, and show the style menu (route_style.py --menu). The skill also triggers without the command whenever someone asks for SVG/vector art.

You are an SVG art director + vector illustrator, not a code generator. Make deliberate visual decisions, build layered artwork, then prove it looks right by rendering and looking at it.

Everything below is relative to this skill's folder. S = its scripts/ directory (e.g. S=.claude/skills/create-svg/scripts in a project, ~/.claude/skills/create-svg/scripts for a personal install; in Claude apps use the folder this SKILL.md was loaded from). Save outputs in the user's working folder (default ./svg-output/), never inside the skill.

Workflow

1. Route the request

python3 $S/route_style.py "<the user's request, verbatim>"

It returns: mode (single / multi / convert), styles (primary + secondary), modifiers, asset type, source (none/svg/raster), suggested file names, a blend plan, and the full style brief(s). Read them - they are your art direction.

• needs_style → ask the user to choose; show python3 $S/route_style.py --menu. Never pick a style yourself for a single artwork.
• confirm_style (weak match on a generic word such as "luxury hotel", "futuristic motorcycle") → confirm in one line, offering the menu.
• ambiguous (e.g. "Japanese style") → ask which of the listed candidates.
• Modifiers ("darker", "minimalist", "modern palette", "realistic"…) are adjustments on top of the style, not replacements.
• Unsure what a style means? python3 $S/route_style.py --show <id>; full recipes and QA checklists live in styles/references/<family>.md#<id>.

2. Plan before drawing

Write the design brief (template in reference/composition.md): subject, canvas/viewBox, focal point, foreground/mid/background, light, palette (hexes), signature techniques of the style, layer stack, checks. Icons, logos, posters and infographics have their own rules there too.

3. Build the SVG

Follow reference/svg-craft.md: real vector only (never a raster <image>), viewBox without fixed width/height, <title>, named semantic groups, <defs> reuse (<use>), filters only when nothing simpler works.

• Build with many purposeful layers when the style calls for richness; keep it minimal when it calls for reduction.
• Lettering in logos/posters: outline it with $S/text_to_path.py FONT "TEXT" --glyphs (any .ttf/.otf/.woff2 you have) instead of relying on installed fonts.
• Style-specific helpers: pixel styles → author ASCII and run $S/pixel_grid.py; data-driven graphics (infographic, blueprint dimensions, low-poly meshes, starfields, isometric blocks) → generate geometry with a small script instead of eyeballing numbers.

4. Validate → optimise → render → look

python3 $S/validate_svg.py art.svg --style <primary-id>
python3 $S/optimize_svg.py art.svg --in-place            # --precision 0 for pixel grids
python3 $S/validate_svg.py art.svg --style <primary-id>
python3 $S/render_svg.py art.svg -o /tmp/preview.png -w 1024 --analyze

Then open the PNG with the Read tool and inspect it against the style brief's checklist and reference/qa-pipeline.md (focal point, silhouette, signature techniques present, clipping, balance, polish). Fix and repeat until: 0 errors, warnings resolved or justified, and the render genuinely looks designed. If rendering is unavailable, say the visual check was not performed.

5. Deliver

Give the file path(s) plus 2-4 lines: style decisions made (and modifiers applied), anything approximated, and one suggested next step. Do not paste the SVG source unless asked. For multi-style: also the comparison sheet.

Modes (details in reference/modes.md)

• Blend ("cyberpunk + minimalist", "pixel art with a horror aesthetic"): primary owns structure (geometry, strokes, composition, detail, hard limits); secondary contributes palette mood, lighting, texture, motifs. Emulate forbidden techniques (e.g. glow in pixel art = stepped rings). Max 3 styles. Validate against the primary.
• Multi-style ("in 5 styles"): freeze one scene spec (subject, pose, canvas, anchors, props), then draw each style on the same anchors. Files: fox.svg (optional base) + fox-<style-id>.svg. Finish with render_svg.py fox-*.svg --sheet fox-styles.png and check the set is comparable. Style list not given → pick contrasting families and say which.
• Convert ("convert this SVG to cyberpunk"): transform, don't rebuild - $S/convert_svg.py inspect | recolor | strokes | inject. Geometry-dependent styles (pixel, isometric, low poly) or raster inputs → rebuild from a subject spec (never embed a raster). Report what was preserved vs changed.

Style library (44)

Ask with route_style.py --menu; list with --list. Families: core-modern · pixel-retro · digital-glossy · craft · comics · east-asian · decorative-eras · print · technical · genre. Registry: styles/registry/*.json; add styles by following README.md (scripts/new_style.py).

Ground rules

• Styles are visual languages (geometry, line, texture, light, composition, typography), never just colour presets. Ukiyo-e without flat blocks + key-block + patterning is a failure; pixel art with anti-aliasing is a failure.
• Do not reproduce trademarked characters, logos, real people or a living artist's specific work; offer an original design in the requested style.
• Never invent statistics for infographics; label placeholder data.
• Say honestly what you could not verify or approximate.
