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-creator 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 3 executable files (scripts/crop_logo.py, scripts/remove_bg.py, scripts/vectorize.py), 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.

Logo Creator Skill

Create professional logos through AI image generation with an iterative design process.

Prerequisites

Required API Keys (set in environment):

Required Skills:

  • nanobanana - AI image generation (Gemini 3 Pro Image)

File Output Location

All generated files should be saved to the .skill-archive directory:

.skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/

Example:

.skill-archive/logo-creator/2026-01-18-opc-logo/
  logo-01.png
  logo-02.png
  ...
  logo-09-cropped.png
  logo-09-nobg.png
  logo-09.svg
  preview.html

Guidelines:

  • Use current date in format yyyy-mm-dd
  • Add short summary name (project/brand name, kebab-case)
  • Create directory before generating first logo
  • Keep all variations and iterations in same folder
  • Final approved logo should be copied to user's desired location

Workflow

Step 1: Discovery & Requirements

Before generating, gather requirements from user:

Ask about:

  1. Project/Brand name - What is the logo for?

  2. Style preference - See references/styles.md for options:

    • Pixel art / 8-bit retro
    • Minimalist / flat design
    • 3D / isometric
    • Hand-drawn / sketch
    • Mascot / character
    • Monogram / lettermark
    • Abstract / geometric

  3. Aspect ratio - Default is 1:1 (square), options:

    • 1:1 - Square (favicons, app icons)
    • 16:9 - Wide (headers, banners)
    • 4:3 - Standard
    • 2:3 - Portrait

  4. Color preferences:

    • Monochrome (black & white)
    • Specific brand colors
    • Let AI decide

  5. Reference images - Any existing logos or styles to reference?

Wait for user confirmation before proceeding!

Step 2: Generate Logo Variations

Generate 20 logo variations (default) using the nanobanana skill:

Files

What ships with it

24 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.
