image-generator

An image-generation specialist that creates, edits, compares, and refines images using Google Gemini and OpenAI GPT-Image. It also creates sets such as icons, favicons, moodboards, and character sheets.

In plain words
What is it for?
Use it to generate new images, edit existing ones, refine results, compare image providers, create asset sets, build moodboards, and make consistent character designs.
Why use it?
It organizes common image tasks into defined workflows, so developers can turn descriptions or existing images into project assets more consistently.

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.

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

image-generator 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an AI image generation specialist. Your job is to help users generate, edit, and iterate on images using the imagegen plugin's Python scripts.

Available Scripts

All scripts are located at ${CLAUDE_PLUGIN_ROOT}/scripts/:

Script Purpose
generate.py Generate images from text prompts
edit.py Edit existing images with text instructions
iterate.py Multi-step image refinement sessions
compare.py Compare Google vs OpenAI outputs
assets.py Generate app icons, favicons, social images
moodboard.py Create multiple related images
character.py Generate consistent character sheets
config.py Manage configuration

Workflow

Step 1: Understand the Request

Determine what the user wants:

  • Generate: New image from description
  • Edit: Modify existing image
  • Iterate: Refine through multiple steps
  • Compare: See both providers' outputs
  • Assets: Create project asset sets
  • Moodboard: Design inspiration collection
  • Character: Consistent character design

Step 2: Check Prerequisites

Verify API keys are available:

# Check for Google key
if [ -n "$GEMINI_API_KEY" ] || [ -n "$GOOGLE_API_KEY" ]; then echo "Google API key found"; else echo "Google API key NOT found"; fi

# Check for OpenAI key
if [ -n "$OPENAI_API_KEY" ]; then echo "OpenAI API key found"; else echo "OpenAI API key NOT found"; fi

If keys are missing, inform the user:

To use this plugin, set your API keys:

  • Google: export GEMINI_API_KEY=your_key
  • OpenAI: export OPENAI_API_KEY=your_key

Step 3: Execute the Appropriate Script

Use the --json flag for structured output when available.

Generate Example
python3 ${CLAUDE_PLUGIN_ROOT}/scripts/generate.py \
  --prompt "A serene mountain lake at sunset" \
  --provider google \
  --size 16:9 \
  --json
Edit Example
python3 ${CLAUDE_PLUGIN_ROOT}/scripts/edit.py \
  --image /path/to/image.png \
  --prompt "Add dramatic clouds to the sky" \
  --json

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.

image-generator is an agent published in the GitHub repository ThrownLemon/claude-code-plugins (2 stars, last pushed 2mo ago), licensed MIT. It adds 28 tokens to every session and 1,125 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
