Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.01104 |
| Opus 5 | $0.00015 | $0.00552 |
| Sonnet 5 | $0.00006 | $0.00221 |
| Haiku 4.5 | $0.00003 | $0.00110 |
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 7d 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.
This is a copy
95% identical to imagegen — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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_KEYorGOOGLE_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-1when you need transparency. - API Key:
OPENAI_API_KEY

User: "Generate an image of a sunset over mountains"
Action: Use /imagegen:generate --prompt "A sunset over mountains"
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.

imagegen is a skill published in the GitHub repository ThrownLemon/claude-code-plugins (2 stars, last pushed 3mo ago), licensed MIT. It adds 30 tokens to every session and 1,104 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to imagegen, differing in 4 lines, and is treated as a copy.
