Generate or edit images using AI models (FLUX, Gemini). An agent skill from Microck/ordinary-claude-skills.

  • Works in 3 steps: Look for a .env file in the project… → Check for OPENROUTER_API_KEY= in the… → If not found, inform the user they need to
  • Scientific illustrations
  • SKILL.md covers Quick Start, API Key Setup, Model Selection and Common Usage Patterns, plus 4 more sections
  • Calls python; needs OPENROUTER_API_KEY

What it does

Generate Image is an agent skill from Microck/ordinary-claude-skills. Generate or edit images using AI models (FLUX, Gemini). Use for scientific illustrations, diagrams, schematics, infographics, concept visualizations, and artistic images. Supports image editing to modify existing images (change colors, add/remove elements, style transfer). Useful for figures, posters, and visual explanations.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Media & Creative, covering Image editing, Image generation and Infographics. It works with Google Gemini and OpenRouter. The repository describes itself as: An unappealing collection of Claude Skills and resources.

When your agent uses it

  • Scientific illustrations
  • Concept visualizations
  • Artistic images

Example prompts

  • “/generate-image”

Requirements

  • Python 3
  • A credential in OPENROUTER_API_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Look for a .env file in the project directory or parent directories
  2. Check for OPENROUTER_API_KEY= in the .env file
  3. If not found, inform the user they need to

What it can do on your machine

Read from SKILL.md and the folder at commit 1056d29. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • openrouter.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENROUTER_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Generate Image loads about 1.2k tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 434 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 434 words (~1,168 tokens).

“Generate and edit high-quality images using OpenRouter's image generation models including FLUX.2 Pro and Nano Banana Pro (Gemini 3 Pro).”
