Logo Design Skill Claude skill

A deep skill that runs a full logo design process (brief, concepts, SVG construction, testing, kit) backed by a 1,400+ logo reference library and Python tools.

Our verdict Recommended

A deep, well-tested single skill with a large, properly licensed reference library and a sensible checkpoint before heavy output; actively maintained.

What Logo Design Skill does

This is one skill, logo-design, but it is large: about 17.6 KB of instructions, 14 reference files and nine Python scripts, built around a reference library of over 1,400 real SVG logos classified by mark type, technique, geometry, subject, typography, mood and industry. The workflow runs discovery, word mapping, choosing a mark type (wordmark, monogram, letterform, pictorial, abstract, emblem, mascot, combination), concepting, geometric SVG construction, optical corrections, color and typography, then testing.

The skill always stops at a checkpoint after building and testing 3 concepts, shown as one overview image with a recommendation; nothing further (color systems, lockups, presentation boards, icon exports) happens until you pick a direction. Its Python tools (standard library only, PNG export falling back across available renderers) audit an SVG against logo principles, build concept overview sheets and test sheets (16px pixel test, one-color, reversed, mirror, shelf test against competitors), generate client presentation boards with industry mockups, and export a full favicon and web-manifest set. The library is explicitly for studying construction and avoiding look-alikes, not for copying. It also has a critique mode, a redesign mode and an identity-system mode for guidelines and sub-brands. The repo has CI tests and a lite zip without the SVG library for size-limited uploads.

Good for

  • Designing a new logo from a brief to production SVG and icon files
  • Critiquing or redesigning an existing logo
  • Agents that can view images, since the skill renders and checks its own drafts

Not for

  • Agents without image viewing (the skill explicitly works best with one)
  • Full brand-identity systems beyond logo and basic lockups (though an identity-system mode is included)

What's inside depth 5/5

One skill with 14 reference files, 9 scripts, a 1,400+ file SVG library, and CI tests — references, scripts and tests together, the top of the depth scale.

Security review

Review before installing

A logo-design skill with reference guides and nine local Python scripts that build, audit and render SVG logos and preview sheets. The one script that starts other programs launches a local image renderer or a headless browser on a temporary profile; none of the scripts we looked at use the network or credentials. SKILL.md sets no allowed-tools. Only render_png.py was read in full; the large icon library was not available.

What we checked

The repository (1560 files) on Oct 29, 2026. Not a full review: 1445 of 1560 files were not downloaded (large repository; we reviewed the skill folders); we read 1 of 9 code files; it relies on code outside the repository: 1445 of 1560 repository files were not available to us (the bundled SVG icon library, plugin manifests, workflows); optional renderers cairosvg, rsvg-convert, inkscape or a browser are used if present.

NVIDIA SkillSpector static scan: 13 pattern hits (Dangerous Code Execution 7, Anti-Refusal 2, Data Flow 2, Privilege Escalation 1, Excessive Agency 1). All 13 SkillSpector hits are in render_png.py: subprocess calls to image renderers and a browser with a temporary profile (the 'keychain' hit is Chrome's --use-mock-keychain flag), a taskkill of that browser process, plus 'never judge' wording in design guidance.

A review, not a certification. Skills change after we check them — read the files before installing.

License

MIT for skill text, scripts, templates and catalog data; the bundled SVG logo files in assets/library/svg/ carry their own license noted in TRADEMARKS.md, and the example brands are fictional.

Can it run unattended?

Not really. It deliberately pauses at a checkpoint for human sign-off before producing the full kit; it is not meant to run unattended.

FAQ

What is the Logo Design Skill?

It is a single comprehensive Claude/Codex/Gemini CLI skill that runs a full logo design process from brief to production SVG files, backed by a library of over 1,400 classified real-world logos and Python tools that audit and test designs.

How do I install it?

In Claude Code, run /plugin marketplace add kaankiziltug/logo-design-skill then /plugin install logo-design@logo-design-skill, or clone the repo and copy skills/logo-design into your agent's skills directory. A size-limited lite zip without the SVG library is also provided.

Does it copy existing logos?

No. The README says the reference library is used to study construction and category conventions and to avoid look-alikes, never to copy. It builds new SVG geometry for each concept.

Is it safe to use?

The tools are standard-library Python with no network calls described, and the repo has CI tests. The bundled logo library has its own license terms separate from the MIT-licensed skill code.
