Image2 Prompt Pack

image2-prompt-pack

This skill should be used when the user asks to convert a PRD, OpenSpec change, or product idea into a structured GPT Image 2 UI prompt pack for generating high-fidelity flat UI reference images. It produces prompt materials, UI type decisions, variants, negative prompts, and reference selection checklists, not frontend code.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
14 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by Jason904 on GitHub. Read the source before you install it.

Installation

Install the Image2 Prompt Pack AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/Jason904/ui-skill-lab/tree/main/.codex/skills/image2-prompt-pack
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Jason904/ui-skill-lab.git /tmp/ui-skill-lab
mkdir -p .claude/skills
cp -r /tmp/ui-skill-lab/.codex/skills/image2-prompt-pack .claude/skills/image2-prompt-pack

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Image2 Prompt Pack in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Image2 Prompt Pack on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Image2 Prompt Pack is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Version: 2.0.0

image2-prompt-pack

Create a structured GPT Image 2 prompt pack from PRD or OpenSpec inputs.

This skill prepares materials for generating a UI reference image. It does not implement UI, extract visual specs from screenshots, or build the final design system.

Trigger Conditions

Use this skill when the user asks to:

generate GPT Image 2 prompts from a PRD
create UI image prompt materials
convert OpenSpec change into reference image prompts
prepare prompt pack for UI screenshot generation
generate variants for a UI reference image
standardize image generation inputs before visual-to-spec

Required Input

text
prd.md

Optional Inputs

text
openspec/changes/<change>/proposal.md
openspec/changes/<change>/specs/**/spec.md
openspec/changes/<change>/design.md
openspec/changes/<change>/tasks.md
brand.md
visual-preferences.md
technical-constraints.md
ui-ux-pro-max output
frontend-design output

Source of Truth

PRD / OpenSpec spec — product goal and user-visible behavior
User visual preference — explicit direction from the user
Technical constraints — frontend feasibility and platform constraints
ui-ux-pro-max — weak design/UX reference only
frontend-design — anti-generic reference only
Skill inference — fallback, must be labeled

Main Workflow

Read PRD and optional OpenSpec files.
Extract product context.
Extract page objective.
Decide UI Type and Layout Paradigm.
Identify required business modules.
Generate visual direction.
Generate layout requirements.
Generate component requirements.
Generate style token seed.
Generate main GPT Image 2 prompt.
Generate negative prompt.
Generate 3-4 variant briefs.
Generate reference selection checklist.
Generate prompt pack summary.

Hard Rules

Do not write frontend code.
Do not generate final tokens.json.
Do not replace visual-to-spec.
Do not default every product to dashboard.
Always create ui-type-decision.md.
Always create reference-selection-checklist.md.
Always create image2-negative-prompt.md.
Always make the UI image frontend-implementable.
Always specify flat UI screenshot unless the chosen UI type explicitly requires scene-led image generation.
Do not produce marketing poster prompts unless the PRD is truly for a landing/marketing page.
Do not produce 3D device mockups.
Do not allow ui-ux-pro-max to override PRD or user constraints.
If UI type is uncertain, mark it review-required.

Frequently asked questions

What does the Image2 Prompt Pack AI skill do?

Why use Image2 Prompt Pack on TypingMind?

Because you install it once and use it with any model. Image2 Prompt Pack is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Image2 Prompt Pack in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Jason904/ui-skill-lab/tree/main/.codex/skills/image2-prompt-pack. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Image2 Prompt Pack?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Image2 Prompt Pack?

As many as you like. As long as a model supports skills, you can use Image2 Prompt Pack with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Image2 Prompt Pack AI skill free?

Yes. It is published on GitHub by Jason904 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
