logo-design

logo-design is a skill for Claude Code from sean-sunagaku/claude-code-plugin. It costs 198 tokens per session (7,413 once invoked), scanned A, original, MIT.

A logo-design workflow that uses repeated plan, create, review, and improvement rounds to produce SVG logo options. SVG is a scalable image format that works well for logos and icons.

In plain words
What is it for?
Use it to create or revise brand logos, symbols, wordmarks, and app icons, with discussions, drafts, notes, and final files saved as project history.
Why use it?
It keeps user feedback and earlier decisions across rounds, so the logo can be refined instead of recreated from scratch each time.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

logo-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/finalize.sh, scripts/init.sh, scripts/new-step.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
