Logo Generation

Generate SVG logo alternatives for a project, then present them in a side-by-side comparison page for review.

Arguments

• $ARGUMENTS - Description of the logo concept, style direction, or project name

Instructions

You are generating SVG logo alternatives and a visual comparison page. Your goal is to produce 6 distinct design directions so the user can pick and refine.

Step 1: Understand the Brief

Determine what the logo should communicate:

1. Project name — What is the logo for?
2. Core concept — What metaphor or visual idea? (e.g., "forge + AI agents", "speed + reliability")
3. Style direction — Modern/minimal, geometric, organic, playful, corporate?
4. Color palette — Dark background? Brand colors? Warm/cool?
5. Shape — Circle, rounded rect, hexagon, freeform?
6. Existing logo — Is there a current logo to improve on? Read it first.

If unclear, ask the user before generating.

Step 2: Design 6 Alternatives

Create 6 meaningfully different SVG logo files. Each should explore a distinct visual direction:

#	Direction	Color	What to Try
1	Minimal	Amber/Gold	Strip to the essential mark. One shape, one gradient. App icon clean.
2	Geometric	Cyan/Teal	Low-poly, faceted, angular. Crystal/tech aesthetic.
3	Organic	Violet/Purple	Flowing curves, natural forms. Warmth and craft.
4	Typographic	Emerald/Green	Lettermark or monogram. The initial letter as hero.
5	Conceptual	Rose/Pink	Symbolic/metaphorical. Combine two ideas into one mark (e.g., flame + orbits).
6	Sci-fi	Blue/Indigo	Orbital, atomic, or space-inspired. Tech gravitas.

CRITICAL: No text in logos. Never use <text> elements, letters, words, or typographic marks in the SVG logos. Every logo must be purely symbolic — shapes, icons, and abstract marks only. Text/wordmarks are added separately by the user if needed.

SVG quality standards:

• Always include explicit width="200" height="200" on the <svg> element (so the standalone file opens at full size in a browser — without it, a bare SVG defaults to 300×150)
• Namespace all id attributes per logo (gradients, filters, clip paths): use halo-1, core-grad-1 in logo-alt-1.svg, halo-2 in logo-alt-2.svg, and so on. Rename both the id AND every url(#id) reference that points to it — renaming one but not the other breaks the fill. When the comparison page inlines every SVG into one document (Step 3), duplicate ids across files collide and marks render with the wrong fills.
• Style marks with presentation attributes or inline styles, not document CSS classes. When inlined via <use> (Step 3), the symbol is cloned into a shadow tree that host-document CSS rules do not reach, so a mark relying on a <style> block with class selectors renders differently inline than standalone. Inline fill/stroke (or the currentColor trick) always render correctly in both contexts.
• Transparent background — do not include a background <rect>. The comparison page provides the dark background via the .well container. Logos must work on any background.
• Use <defs> for gradients, filters, and reusable elements
• For circular glow halos, use radialGradient fills (not blur filters). Blur filters (feGaussianBlur) clip to a rectangular region and render as squares at small sizes. Use a radialGradient with opacity tapering to 0 at the edge, applied to a circle larger than the core element. Example:

  <radialGradient id="halo" cx="50%" cy="50%" r="50%">
    <stop offset="0%" stop-color="#COLOR" stop-opacity="0.6"/>
    <stop offset="40%" stop-color="#COLOR" stop-opacity="0.15"/>
    <stop offset="100%" stop-color="#COLOR" stop-opacity="0"/>
  </radialGradient>
  <circle cx="X" cy="Y" r="20" fill="url(#halo)"/>
  <circle cx="X" cy="Y" r="5" fill="#COLOR" opacity="0.9"/>
  

• Reserve feGaussianBlur for trail/path effects where rectangular clipping is less visible
• Use linearGradient for directional surfaces, radialGradient for point-light and glow
• Layer elements: ambient light → structure → hero element → accents
• Keep the viewBox at 0 0 200 200 for the main logo
• Center precisely: Calculate the bounding box of all visible elements and ensure its center is at (100, 100). For asymmetric layouts (e.g., 3 nodes around a hub), offset the composition so the bounding box center — not just the primary element — sits at (100, 100). Verify: (minX + maxX) / 2 ≈ 100, (minY + maxY) / 2 ≈ 100.

Save to the project's assets/ directory:

• assets/logo-alt-1.svg through assets/logo-alt-6.svg
• If there's an existing logo, include it as the "Current" option

Step 3: Generate Comparison Page

Create assets/logo-compare.html — a dark-themed grid page showing all options side-by-side.

CRITICAL: Inline the SVGs — do not use <img src="logo-alt-N.svg">. A relative <img src> renders on the local filesystem but breaks when the page is registered as an Argus artifact (Step 4b): the artifact viewer runs under a strict CSP with no network and no relative-path resolution, so every logo shows as a broken image. Inline each SVG instead so one page works in both contexts.

How to inline: Define each logo once as a hidden <symbol>, then render it with <use> at two sizes — the full-size well AND a small avatar (~36px round). The avatar is the real selection test: these marks become bot/GitHub/Linear avatars, and small-size legibility is what matters.

To turn a logo-alt-N.svg file into a symbol: copy everything inside its <svg> element into a <symbol id="logo-N" viewBox="0 0 200 200">…</symbol>. Keep the same viewBox the file uses (0 0 200 200). Ensure ids inside each file are namespaced per logo (see Step 2) so inlined gradients/filters do not collide.

<symbol>/<use> is preferred over data-URIs: one definition per mark, small file, readable markup, and it renders both locally and in the artifact viewer.

Step 4: Open and Present

1. Open the comparison HTML in the browser: open assets/logo-compare.html
2. Present a summary table of all options with name and concept
3. Offer to refine, mix elements, or apply the chosen design

Optional — register for mobile review (Argus): If the mcp__argus__artifact_register tool is available, offer to register assets/logo-compare.html as an Argus artifact so the user can review the options on their phone. Pass the absolute path to the HTML file. This works only because Step 3 inlines the SVGs — a page using relative <img src> renders as broken images in the artifact viewer. If the tool is not available, skip silently.

Step 4b: Refine the Winner (if requested)

When the user wants to vary a single element (e.g., center color, accent style):

1. Create 4-5 variants that ONLY change the requested element
2. Name each variant file descriptively (e.g., center-1-white.svg, center-2-gold.svg), namespacing ids per variant (see Step 2)
3. Generate a comparison page (assets/<element>-compare.html) using the same inlined <symbol>/<use> template as Step 3 — do NOT use <img src>, so the page renders if registered as an Argus artifact
4. Open it for the user to pick
5. Apply the chosen variant to the main logo and clean up variant files

Step 5: Apply the Winner

When the user picks a logo:

1. Copy it to favicon.svg in the project root
2. Add the logo to the top of the project's README, centered at 120px width:

   <p align="center"><img src="favicon.svg" width="120"></p>
   

   Insert this as the very first line, before any existing heading or content.
3. If raster avatars are needed (GitHub org/Linear/bot avatars often require PNG), export a size set (512, 256, 64) from favicon.svg. sips cannot convert SVG to PNG — it only handles raster formats. Use whichever of these is installed:

   rsvg-convert -w 512 -h 512 favicon.svg -o favicon-512.png   # librsvg, preferred
   resvg favicon.svg favicon-512.png --width 512 --height 512   # resvg
   convert -density 384 -background none favicon.svg -resize 512x512 favicon-512.png   # ImageMagick (high -density rasterizes with headroom before -resize downscales)
   

   Use a transparent background (-background none / default for the others) so the mark drops onto any avatar background. Repeat per size, or export 512 once and downscale.
4. Clean up the logo-alt-*.svg files and logo-compare.html (and any *-compare.html from Step 4b)

Design Principles

1. Distinct directions — Each alternative should be recognizably different at a glance, not minor tweaks
2. SVG-native — Use gradients, filters, and transforms. No raster effects.
3. Scale well — Design should read clearly at 32px (favicon) and 200px (logo)
4. Dark-first — Assume dark backgrounds. Light elements should glow.
5. Layered depth — Background → ambient glow → structure → hero → sparkle/accent
6. Name each option — Short, memorable names make discussion easier ("Orbital Forge" vs "Alt 5")
7. Unique palettes — Each alternative MUST use a different color scheme. Never repeat the same palette across options.
