imagegen

imagegen is a skill for Claude Code, Codex from int2t05/engineering-skills. It costs 120 tokens per session (1,224 once invoked), scanned A, original, MIT.

A skill for generating design-reference images for brand identity, website sections, or mobile-app screens. It produces images only, not frontend code.

In plain words
What is it for?
Use it for brand boards and logo concepts, one horizontal reference image per website section, or mobile screen and multi-screen flow concepts.
Why use it?
It helps turn a visual brief into concrete references before implementation, while keeping brand, web, and mobile concepts in separate workflows.

Skill for Claude CodeCodex

Written for Claude Code and Codex: ${CLAUDE_PLUGIN_ROOT} variable, but also agents/openai.yaml present.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

imagegen 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Imagegen

Generate premium design reference images across three modes — brand identity, web sections, mobile screens — that feel art-directed and implementation-friendly, not generic AI slop. Output is images only, never code.

When to use

  • Brand identity boards, logo concepts, identity systems → brand mode
  • Website section reference images (one horizontal image per section) → web mode
  • Mobile app screen concepts and multi-screen flows → mobile mode
  • Triggers on "brand kit", "logo 设计", "品牌系统", "web design image", "landing page image", "网站设计图", "mobile design image", "app screen image", "移动端设计图", "手机界面图"

Not for: frontend code (use frontend-design); image-to-code pipeline (use image-to-code).

Tool note: use an available image-generation tool — do not bind to a specific product.

Steps

1. Pick the mode and load its workflow

Infer from the brief which mode fits, then load that mode's reference for the full workflow. Each mode has its own section-count rule, composition logic, and anti-slop list.

If the brief spans modes (e.g. a brand system plus web mockups), lead with the primary mode and note the secondary. Do not mash modes into one frame.

2. Hold one art direction across the set

Whatever the mode, lock one visual direction — palette, typography, imagery treatment, corner radius, density — and keep it consistent across every image in the set. Screen 3 must not drift into a different product world than screen 1. The mode reference defines the mode-specific bible; this step is the shared consistency spine across the whole set.

3. Ban AI slop (all modes)

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.
