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

imagegen 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 1mo ago.

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.

Origin

Image Generation Skill

This skill enables AI-powered image generation, editing, and asset creation using Google Gemini (Gemini) and OpenAI GPT-Image.

When to Use

Activate this skill when the user wants to:

  • Generate images from text descriptions
  • Edit or modify existing images
  • Create project assets (icons, favicons, social images)
  • Generate design inspiration (moodboards)
  • Create consistent character designs
  • Compare different AI image providers

Available Commands

Command Use For
/imagegen:generate Generate images from prompts
/imagegen:edit Edit existing images
/imagegen:iterate Refine images through multiple steps
/imagegen:compare Compare Google vs OpenAI
/imagegen:assets Generate project assets
/imagegen:moodboard Create design inspiration sets
/imagegen:character Create consistent character sheets
/imagegen:config Configure defaults

Delegation

For complex image generation tasks, delegate to the image-generator subagent which has access to all generation scripts and can handle multi-step workflows.

Quick Reference

Providers

Google Gemini (Gemini)

  • Models: gemini-2.5-flash-image, gemini-3-pro-image-preview
  • Best for: Character consistency, multi-turn iteration, style variety
  • API Key: GEMINI_API_KEY or GOOGLE_API_KEY

OpenAI GPT-Image

  • Models: gpt-image-2 (default), gpt-image-1.5, gpt-image-1 (the only one supporting transparent backgrounds), gpt-image-1-mini
  • Best for: Text in images, precise edits. gpt-image-2 has built-in reasoning ("thinking mode") and is state-of-the-art. Use gpt-image-1 when you need transparency.
  • API Key: OPENAI_API_KEY
