gemini-image-generator

gemini-image-generator is a skill for Claude Code, Codex from mkdev-me/agent-skills. It costs 13 tokens per session (356 once invoked), scanned A, original, MIT.

A skill for generating images with Google Gemini from written descriptions, or changing an existing image using a reference. It supports 1K, 2K, and 4K output sizes.

In plain words
What is it for?
Use it to create illustrations, scenes, or visual variants and save them to chosen output paths.
Why use it?
It provides a repeatable command-line process for creating image assets without manually operating an image editor. Existing images can guide the generated result.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is cd scripts && python3 -m venv venv && ./venv/bin/pip install -r requirements.txt.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

gemini-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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate.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.

What it actually says

gemini-image-generator

Instructions

Use this skill to generate images using Google Gemini's image generation model. The skill supports:

  • Text-to-image generation from prompts
  • Image-to-image generation with a reference image
  • Multiple output sizes (1K, 2K, 4K)
  • Custom output paths

The API key must be set via the GEMINI_API_KEY environment variable.

Parameters

  • --prompt (required): The text prompt describing the image to generate
  • --output (required): Output file path for the generated image
  • --reference: Optional reference image for style/content guidance
  • --size: Image size - "1K", "2K", or "4K" (default: 4K)

Examples

Basic text-to-image generation

./scripts/generate.py --prompt "A serene mountain landscape at sunset" --output images/landscape.png

With reference image for style guidance

./scripts/generate.py --prompt "Same character but wearing a party hat" --reference images/character.png --output images/party.png

Different output size

./scripts/generate.py --prompt "Abstract art" --output art.png --size 2K

Setup

Before first use, set up the virtual environment:

cd scripts && python3 -m venv venv && ./venv/bin/pip install -r requirements.txt

Set your API key:

export GEMINI_API_KEY="your-api-key-here"
Files

What ships with it

2 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.
