What it does
Image Gen is an agent skill from nicknisi/claude-plugins. Generate or edit images via Google Gemini (nano-banana-pro) or OpenAI gpt-image-2. Trigger on "generate image", "create diagram", "edit image", or "make illustration". Supports 1K/2K/4K resolution, masked inpainting, and text-accurate generation.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `dist/generate_image.js`, `package.json` and `scripts/generate_image.ts`).
It sits in Media & Creative, covering Image generation and Image editing. It works with Google Gemini and OpenAI. The repository describes itself as: Nick's own marketplace of Claude Plugins. The licence is MIT.
When your agent uses it
- Make illustration
- Tasks that involve Image generation
- Tasks that involve Image editing
Example prompts
- “generate image”
- “create diagram”
- “edit image”
- “/image-gen”
Requirements
- Node.js
- A credential in GEMINI_API_KEY
- A credential in GOOGLE_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 6a6decd. 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
Ships 1 file in scripts/ (JavaScript and TypeScript), which the agent can run.
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
OPENAI_API_KEYGEMINI_API_KEYGOOGLE_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Image Gen loads about 502 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 166 words of instructions outside code blocks.
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 passed
The automated check found no risky patterns in SKILL.md.
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); the scripts in this folder are not scanned.

- image-gen
- description
- Generate or edit images via Google Gemini (nano-banana-pro) or OpenAI gpt-image-2. Trigger on "generate image", "create diagram", "edit image", or "make illustration". Supports 1K/2K/4K resolution, masked inpainting, and text-accurate generation.
Image Generation & Editing
Multi-provider image generation. Default provider is Gemini (nano-banana-pro); pass --provider openai to use gpt-image-2.
Which provider to pick
- Gemini (default): general illustrations, quick diagrams, visual imagery. Accepts
--input-imagerepeatedly for multi-image composition. - OpenAI: anything where text rendering matters (infographics, slide-like images, dense-label diagrams, logos with text), or when you need masked inpainting on edits.
Usage
The skill ships a pre-bundled Node script — no tsx or dependency install needed. The script's --help is the authoritative flag reference; run it rather than guessing:
node ${CLAUDE_PLUGIN_ROOT}/skills/image-gen/dist/generate_image.js --helpGenerate:
node ${CLAUDE_PLUGIN_ROOT}/skills/image-gen/dist/generate_image.js \
--prompt "your description" --filename "output.png"Edit (image-to-image):
node ${CLAUDE_PLUGIN_ROOT}/skills/image-gen/dist/generate_image.js \
--prompt "editing instructions" --filename "output.png" \
--input-image "path/to/input.png"API keys
Read from the environment unless --api-key overrides: Gemini uses GEMINI_API_KEY or GOOGLE_API_KEY; OpenAI uses OPENAI_API_KEY. If only OPENAI_API_KEY is set, the provider defaults to OpenAI.
Conventions
- Name files
YYYY-MM-DD-HH-MM-SS-descriptive-name.png. - For blog diagrams, use OpenAI at
2K— anything with readable labels or callouts needs its text fidelity. Save to the post's content dir (e.g.src/content/blog/post-name/) and prefer clean, minimalist styles. - The script prints the saved path. Report that path to the user; do not read the image back.
