generate-image

generate-image is a skill for Claude Code, Codex from magic3007/dotfiles. It costs 71 tokens per session (1,619 once invoked), scanned A, a copy of generate-image, MIT.

An image-generation and editing skill for creating photos, illustrations, artwork, concept art, and other visual assets with AI models. It can also modify an existing image.

In plain words
What is it for?
Use it to create new images or edit existing ones, including visuals for presentations, documents, websites, and creative projects.
Why use it?
It removes the need to source or manually create every general-purpose visual asset. It gives an agent a defined workflow for generating or changing images.

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

generate-image 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 today.

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

Origin

This is a copy

97% identical to generate-image — 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

Generate Image

Generate and edit high-quality images using OpenRouter's image generation models including FLUX.2 Pro and Gemini 3.1 Flash Image Preview.

When to Use This Skill

Use generate-image for:

  • Photos and photorealistic images
  • Artistic illustrations and artwork
  • Concept art and visual concepts
  • Visual assets for presentations or documents
  • Image editing and modifications
  • Any general-purpose image generation needs

Use scientific-schematics instead for:

  • Flowcharts and process diagrams
  • Circuit diagrams and electrical schematics
  • Biological pathways and signaling cascades
  • System architecture diagrams
  • CONSORT diagrams and methodology flowcharts
  • Any technical/schematic diagrams

Quick Start

Use the scripts/generate_image.py script to generate or edit images:

# Generate a new image
python scripts/generate_image.py "A beautiful sunset over mountains"

# Edit an existing image
python scripts/generate_image.py "Make the sky purple" --input photo.jpg

This generates/edits an image and saves it as generated_image.png in the current directory.

API Key Setup

CRITICAL: The script requires an OpenRouter API key. Before running, check if the user has configured their API key:

  1. Look for a .env file in the project directory or parent directories
  2. Check for OPENROUTER_API_KEY=<key> in the .env file
  3. If not found, inform the user they need to:
    • Create a .env file with OPENROUTER_API_KEY=your-api-key-here
    • Or set the environment variable: export OPENROUTER_API_KEY=your-api-key-here
    • Get an API key from: https://openrouter.ai/keys

The script will automatically detect the .env file and provide clear error messages if the API key is missing.

Model Selection

Default model: google/gemini-3.1-flash-image-preview (high quality, recommended)

Available models for generation and editing:

  • google/gemini-3.1-flash-image-preview - High quality, supports generation + editing
  • black-forest-labs/flux.2-pro - Fast, high quality, supports generation + editing

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.
