Your logo lives in a screenshot a designer friend once sent you, or in a blurry image that becomes a smudge the moment it shrinks to a browser-tab icon. The result: no clean favicon, no light version for dark backgrounds, no file to hand to the printer. This skill asks the AI to follow a real designer's process and give you vector files (SVG: a format that stays sharp at every size, from favicon to shop sign).
What does the Logo Design skill do, and who is it for?
A skill is a folder of instructions and small tools that Claude loads when the task calls for it. This one, published on GitHub by the account kaankiziltug, has Claude follow an identity designer's process, from the first brief to production-ready SVG files and brand guidelines. The repository describes it as working with Claude, Gemini CLI, Codex and other AI agents.
It ships with a reference library of more than 1,400 real-world SVG logos, classified by mark type, technique, geometry, typography, mood and industry. It is not there for copying: the skill uses it to study how logos are built, map the conventions of a sector and avoid producing a look-alike.
It is useful if you are a freelancer or run a small business, have no budget for a designer yet, and want a working base rather than a logo generated as a single image. The result depends on your brief and does not replace a designer's eye.
How do you install the Logo Design skill?
- In Claude Code: add the repository as a marketplaceType this command in Claude Code.
/plugin marketplace add kaankiziltug/logo-design-skill - Install the pluginThen the second command.
/plugin install logo-design@logo-design-skill - Manual optionIf you have downloaded the repository from GitHub, just copy the skill folder into your personal skills.
cp -r logo-design-skill/skills/logo-design ~/.claude/skills/logo-design - In Claude.aiA skill is uploaded as a zip file. Claude's help centre points to Customize > Skills, then “Upload a skill”; the project README mentions Settings > Capabilities > Skills. Menus can change, so go by what you see on screen.

The tools bundled with the skill need Python 3.8 or later, with no extra libraries. To export PNG or ICO files (the favicon format), it uses whatever renderer your machine has: cairosvg, rsvg-convert, Inkscape, a Chromium-based browser (Chrome, Edge, Brave) or macOS Quick Look.
How does the skill work, step by step?
The SKILL.md file splits the work into seven phases. The first three: questions to build the brief (in quick mode, five at most, in a single message), a research and strategy phase, then concepts.
Next comes the most useful rule: the concept checkpoint. Claude shows you the directions as one overview image, with its recommendation, and produces nothing else until you choose a direction.
Phase 5 is a test-and-refine loop, run at least twice. Phase 7, building the kit, only starts once you say yes.
What should you ask for a small business logo?
The README gives a plain-language request: three wordmark directions for a coffee roaster. Here is a prompt to copy and adapt to your business:
Use the logo-design skill.
I run [company name], [business] in [city].
Customers: [who they are]. Direct competitors: [2 or 3 names].
What the logo should convey: [3 words]. Avoid: [colours, sector clichés].
Propose three logo directions, at least one of which works in a single colour.
Stop after the concepts: I choose before you build the kit.The sharper the brief (your customers, your competitors, what you refuse), the less generic the directions. To find the words that describe the style you want, see 50 designer words for your image prompts.
What tests does every logo go through?
The README lists, among others:
- a 16 pixel legibility test;
- a one-colour version;
- a reversed version (light on dark);
- the squint test and the mirror test;
- a comparison against competitors' logos.
The skill requires a logo to work tiny as well as huge, and its one-colour and greyscale versions to still hold up. If the idea does not survive being shrunk to 16–24 pixels, it simplifies the drawing or adds a small-size version.
For you, this is what separates a nice drawing from a usable logo: the browser-tab icon, the stamp on an invoice, the embroidery on a polo shirt.
What does the final kit contain?
- horizontal, stacked, symbol-only and wordmark-only lockups, plus a small-size cut;
- colours, a presentation board and brand guidelines;
- a favicon, app-icon and web-icon set, with the web manifest, produced by a bundled export script.
The repository also provides a script to audit an SVG file yourself. The README shows this command:
python3 scripts/svg_audit.py my-logo.svgWhich settings give better results?
- Set the language: the skill's sources (README and SKILL.md) are in English. If you work in another language, say so in your request, or once and for all in your CLAUDE.md file.
- Pick a model that can see images: the project says the skill works best that way, because it renders and checks its own drafts.
- For other visuals (banners, slides), see our Claude Design guide instead.
What are the limits and precautions?
- The skill is free, under the MIT licence. The logos in the library remain the property of their owners: they are included for reference and education, outside the MIT licence.
- The brands in the repository's examples are fictional. The project is young: repository created on 26 September 2026, last push on 30 September 2026 at the time of writing.
- SKILL.md tells Claude not to recreate an existing mark, but nothing says this replaces a proper search. Before you file or print, check the INPI trademark database (France); the INPI also offers a similarity search (spelling, sound and meaning), and its availability check for a trademark or logo starts at €50.
Read before you install. This skill contains Python scripts that run on your computer. Anthropic recommends using only skills from trusted sources, meaning ones you created yourself or obtained from Anthropic; this skill comes from a third party, so review it: all its files (SKILL.md, scripts, resources), looking for any network call or file access unrelated to its purpose. My advice: install from github.com/kaankiziltug/logo-design-skill, not from a copy. My method for reviewing a skill is in install a skill safely.

Once the logo is ready, you still need a website that shows it off, from the favicon to the brand colours. That is what we build in our websites work.
