Logo Design Skill for Claude & AI Agents

A comprehensive logo-design skill that turns Claude — or any agent that supports Agent Skills, such as Gemini CLI, Codex CLI, Cursor or GitHub Copilot — into a disciplined identity designer, from the first brief to production-ready SVG files and brand guidelines.

• Principles & process — discovery and briefs, word mapping, choosing the right mark type, concepting, geometric construction, optical corrections (overshoot, bone effect, irradiation…), colour, typography, lockups, testing, presentation, delivery, redesigns and identity systems.
• A reference library of 1,400+ real-world SVG logos, each visually classified by mark type, technique, geometry, subject, typography, mood and industry — searchable from the command line and browsable in a local gallery. Used to study construction, map category conventions and avoid look-alikes (never to copy).
• Dependency-free Python tools — audit an SVG against logo principles, build concept overview sheets and test sheets (16 px pixel test, one-colour, reversed, squint, mirror, contexts, competitor shelf test), create client presentation boards with industry-specific mockups, render PNGs, and export a complete favicon / app-icon / web-manifest set.

How it works

flowchart LR
    A[Briefquestions or stated assumptions] --> B[Researchcategory conventions in the library]
    B --> C[Concepts8–12 one-liners → build 3 in SVG]
    C --> D[Test & refineaudit · 16 px · one-colour · shelf test]
    D --> E{{Checkpointshow concepts, recommend, stop}}
    E -- "you pick a directionand ask for the kit" --> F[Kitcolour · lockups · board · icons · guidelines]
    E -- "you want changes" --> C

The skill always stops at the checkpoint: it shows the concepts as one overview image with a recommendation and offers the full kit. Nothing else is produced until you choose a direction — the kit is most of the work and only makes sense for an approved idea.

Claude Code — manual

Copy the skill folder into your personal (all projects) or project skills directory:

git clone https://github.com/kaankiziltug/logo-design-skill.git
cp -r logo-design-skill/skills/logo-design ~/.claude/skills/logo-design          # personal
# or: cp -r logo-design-skill/skills/logo-design .claude/skills/logo-design     # per project

Claude.ai / Claude Desktop

Download logo-design.zip from the Releases page (or run python3 tools/package_skill.py) and upload it under Settings → Capabilities → Skills. If your upload has a size limit, use logo-design-lite.zip (everything except the SVG files themselves).

Gemini CLI, Codex CLI and other agents

The skill uses the open Agent Skills format (a folder with a SKILL.md), so it works in any agent that supports skills — the instructions are plain Markdown and the tools are plain Python. Clone once, then copy the folder into your agent's skills directory:

git clone https://github.com/kaankiziltug/logo-design-skill.git
