What Is the GPT-Image2 Agent Skill Library?

The GPT-Image2 agent skill library is a reusable skill package that equips AI agents with a structured, repository-backed knowledge base for generating high-quality image-generation prompts.

The GPT-Image2 agent skill library lives in the freestylefly/awesome-gpt-image-2 repository and serves as a bridge between static style definitions and dynamic agent reasoning. This library transforms the centralized data/style-library.json catalog into an actionable tool that agents like Claude Code, Codex, or any .agents-compatible runtime can invoke to produce production-ready prompts instantly.

Architectural Components

Centralized Data Source

At the foundation lies data/style-library.json, the single source of truth containing visual-style definitions, template categories, scene tags, pitfalls, and concrete example cases. This JSON file drives both the website UI and the agent skill, ensuring agents always access the latest community-curated styles without version drift.

Skill Definition

The agents/skills/gpt-image-2-style-library/SKILL.md file declares the skill's purpose, workflow, and output defaults. According to this specification, the agent executes a four-step pipeline:

1. Detect the input language automatically
2. Identify the target output type requested by the user
3. Match the request against template categories → visual-style tags → scene tags → example cases
4. Compose a production-ready GPT-Image2 prompt including composition details, materials, aspect ratios, and negative constraints

Generation Pipeline

The scripts/generate-style-skill.mjs script reads data/style-library.json and produces a ready-to-publish skill package containing SKILL.md, assets, and generated reference files. Invoke this build process via:

npm run generate:style-skill

Installation Infrastructure

Two scripts handle deployment to local agent runtimes:

• scripts/install-style-skill.mjs copies the generated skill into local agent directories (~/.codex/skills, ~/.claude/skills, ~/.agents/skills)
• agents/skills/gpt-image-2-style-library/bin/install.mjs provides a CLI wrapper (gpt-image-2-style-library install [all|codex|claude-code|agents]) that validates targets and triggers the copy operation

Run the installation via:

npm run install:skill

Or use the CLI directly after the skill is built:

gpt-image-2-style-library install all

Package Distribution

The agents/skills/gpt-image-2-style-library/package.json declares the skill as a distributable npm package, enabling installation via npx skills add … or direct publishing to npm registries.

Installation Methods

You can deploy the GPT-Image2 agent skill library using three distinct approaches depending on your environment.

Global npx installation (recommended for immediate use across multiple agents):

npx skills add freestylefly/awesome-gpt-image-2 \
    --skill gpt-image-2-style-library \
    --agent claude-code codex \
    --global --yes --copy

Local npm workflow (for development or customization):

npm run generate:style-skill   # Creates skill bundle from data/style-library.json

npm run install:skill          # Copies to ~/.codex/skills, ~/.claude/skills, etc.

Direct CLI invocation (after local installation):

gpt-image-2-style-library install all

Runtime Usage

Once installed, agents invoke the skill programmatically. According to the source implementation in agents/skills/gpt-image-2-style-library/SKILL.md, the workflow enables language-aware prompt generation:

await agent.runSkill('gpt-image-2-style-library', {
  request: '生成一个未来城市的概念海报',
  language: 'zh'
});

The skill processes the request through its four-step reasoning pipeline, matching the input against the centralized JSON catalog to emit a complete GPT-Image2 prompt with specific composition guidance, material specifications, aspect ratio constraints, and negative prompts to avoid.

Summary

• The GPT-Image2 agent skill library transforms static JSON style definitions into dynamic agent capabilities for automated prompt engineering.
• The architecture centers on data/style-library.json as the single source of truth, consumed by both human-facing UIs and machine agents to ensure consistency.
• Installation scripts (scripts/install-style-skill.mjs and bin/install.mjs) deploy the skill to local agent runtimes including Claude Code, Codex, and generic .agents directories.
• The generation pipeline (scripts/generate-style-skill.mjs) ensures the skill package always reflects the latest community-curated styles without manual synchronization.
• Agents invoke the skill via standardized APIs to produce production-ready image-generation prompts structured with composition details, materials, aspect ratios, and negative constraints.

Frequently Asked Questions

What is the primary purpose of the GPT-Image2 agent skill library?

The library provides AI agents with a structured, repository-backed knowledge base for generating high-quality image-generation prompts. It bridges the static data/style-library.json catalog with dynamic agent reasoning, enabling Claude Code, Codex, and compatible runtimes to understand user intent, select appropriate visual styles, and emit production-ready GPT-Image2 prompts complete with composition and constraint specifications.

Which file contains the master catalog of styles and templates?

The data/style-library.json file serves as the canonical source for all visual-style definitions, template categories, scene tags, and example cases. This JSON file drives both the website UI and the agent skill, guaranteeing that agents always reference the latest community-curated content without requiring manual updates to the skill package itself.

How do I install the skill for local AI agents?

You have three installation options: use npx skills add freestylefly/awesome-gpt-image-2 for immediate global installation across multiple agent types, run npm run generate:style-skill followed by npm run install:skill to build and deploy locally from source, or execute gpt-image-2-style-library install all via the CLI wrapper after initial setup. These commands write files to ~/.codex/skills, ~/.claude/skills, and ~/.agents/skills.

Can I use this skill with any AI agent runtime?

Yes, the skill supports any runtime compatible with the .agents skill specification, including Claude Code and Codex. The agents/skills/gpt-image-2-style-library/SKILL.md definition follows standard agent-skill conventions, and the installation script targets multiple agent directories simultaneously, making the skill portable across different AI agent frameworks that support the skill manifest format.
