What it does

Generate Image is an agent skill from tsingyuai/growth-lab. Generate, edit, or batch-create SEO, marketing, social, and document images with Gemini or OpenAI through the repository-owned Growth Lab image client. Use when a page or content loop needs illustrations, diagrams, covers, reference-image edits, multiple candidates, or verified image text and composition. This is the only AI image-generation Executor in Growth Lab.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `agents/openai.yaml`).

It sits in Media & Creative, covering Image generation. It works with OpenAI and Google Gemini. The repository describes itself as: An end-to-end growth tool that understands the product, fetch the data it needs, researches the market, executes campaigns, and reviews results to improve the next round of… The licence is Apache-2.0.

Requirements

A credential in OPENAI_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 2d0807c. 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 script files (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
- node
- python
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:
- GEMINI_API_KEY
- OPENAI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Generate Image loads about 1k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 441 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~96
When it runs · the whole SKILL.md, loaded when a task matches: ~1k

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.

name: generate-image
description: Generate, edit, or batch-create SEO, marketing, social, and document images with Gemini or OpenAI through the repository-owned Growth Lab image client. Use when a page or content loop needs illustrations, diagrams, covers, reference-image edits, multiple candidates, or verified image text and composition. This is the only AI image-generation Executor in Growth Lab.

Generate images

Use executors/generate-image/generate-image.mjs for text-to-image and reference-image editing. It is a repository-owned, zero-dependency Node.js client. Do not call Codex system Skills, private scripts, or files under ~/.codex.

Define the asset

Specify:

placement and purpose;
subject and visible action;
composition and aspect ratio;
visual style and brand palette;
exact text when text is essential;
details that must appear;
artifacts, logos, watermarks, and unrelated text to exclude.

Prefer real product screenshots when the image explains product behavior. Use generated visuals for concepts, scenes, covers, illustrations, diagrams, and supporting examples.

Generate

Use a prompt file for long or multilingual prompts:

bash

node executors/generate-image/generate-image.mjs \
  --out <output.png> --prompt-file <prompt.txt>

Choose OpenAI explicitly when appropriate:

bash

node executors/generate-image/generate-image.mjs \
  --model gpt-image-2 --out <output.png> \
  --prompt-file <prompt.txt>

--model accepts any gpt-image-* ID (sent to the OpenAI Images API at OPENAI_BASE_URL) or any gemini-*image* / nano-banana* ID (sent to the Gemini API at GOOGLE_GEMINI_BASE_URL). Compatible gateways may expose suffixed or tiered model IDs; list them with the gateway's /v1/models before choosing.

Add one --ref <image> argument for each reference image used in an edit.

For JSONL batch generation, put one job per line with prompt or prompt_file, out, and optional model, refs, size, or quality:

bash

node executors/generate-image/generate-image.mjs \
  --batch <jobs.jsonl> --out-dir <directory> --concurrency 3

Read GEMINI_API_KEY or OPENAI_API_KEY from the process environment, root .env.local, or root .env, in that precedence order. Use GOOGLE_GEMINI_BASE_URL or OPENAI_BASE_URL only for a compatible HTTPS endpoint. Keep credentials out of prompts, files, logs, and commits. Do not read credentials from another application's private authentication files.

Before the first provider call, run python models/onboard-growth-lab/scripts/check_configuration.py. If image generation is optional-missing, tell the user that collection, copywriting, review, and deterministic rendering can continue without an image API. When generated assets are requested, point to CONFIGURATION.md, name the OpenAI and Gemini field options, and wait for the user to configure or skip. Never ask them to paste a key into the conversation. A paid verification call requires separate approval.

Show full SKILL.md (146 more words)Show less

Control text and structure

List every required label verbatim in the prompt. State that all rendered text must match those strings exactly and that the image may contain no other text or watermark.

For a structured diagram, enumerate nodes, arrows, order, grouping, and direction explicitly. For edits, state what must remain unchanged.

Inspect every result

Use the Runtime's image viewer at full size. Check:

relevance to the adjacent page content;
every rendered character;
subject and factual details;
arrow direction, order, and grouping;
visual artifacts and unintended objects;
crop, aspect ratio, and mobile readability;
consistency with the product's visual language.

Regenerate with one targeted correction when the result fails. Use a deterministic code-native graphic when repeated attempts cannot render exact dense text or structure.

Store the selected asset in the product's normal public directory with a stable descriptive filename, suitable compression, explicit dimensions, and descriptive alt text.

When should I use Generate Image?

Generate Image fits situations like: content loop needs illustrations; reference-image edits; multiple candidates; verified image text and composition.

How do I install Generate Image in Claude Code?

Run `npx skills add tsingyuai/growth-lab --skill generate-image -a claude-code`. Or copy the skill folder (executors/generate-image in tsingyuai/growth-lab) into .claude/skills/generate-image in your project. Claude Code loads it when a task matches its description.

Can I use Generate Image in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tsingyuai/growth-lab --skill generate-image -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/generate-image, .gemini/skills/generate-image, .github/skills/generate-image and .opencode/skills/generate-image in your project.

What does Generate Image need to run?

Going by SKILL.md and its folder, Generate Image needs JavaScript for the scripts in its folder, the command-line tools its instructions call (node and python) and credentials named GEMINI_API_KEY and OPENAI_API_KEY. Our summary lists: Python 3; Node.js; A credential in GEMINI_API_KEY; A credential in OPENAI_API_KEY.

Does Generate Image access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Generate Image safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
