  • 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.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by xerrors on GitHub. Read the source before you install it.

Installation

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

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. 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.
2

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/xerrors/Yuxi.git /tmp/Yuxi
mkdir -p .claude/skills
cp -r /tmp/Yuxi/backend/package/yuxi/agents/skills/buildin/image-gen .claude/skills/image-gen
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Image Gen 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 Image Gen 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 Image Gen 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.

图片生成技能

当用户要求生成图片、海报、插画、文生图,或明确提到 Qwen-Image 时,使用此技能组织图片生成流程。

默认生成接口

默认使用 SiliconFlow 的 Qwen-Image 接口:

  • Endpoint: POST https://api.siliconflow.cn/v1/images/generations
  • Model: Qwen/Qwen-Image
  • 默认参数:
    • negative_prompt: ""
    • num_inference_steps: 20
    • guidance_scale: 7.5

调用外部接口时,必须在 Agent 沙盒执行环境中读取 SILICONFLOW_API_KEY。不要依赖后端进程环境变量。

操作流程

  1. 明确用户要生成的图片内容、风格、尺寸或约束;信息不足但不影响生成时,使用合理默认值,不要反复追问。
  2. 使用可用的执行工具在沙盒中运行脚本,调用图片生成接口,传入用户需求整理后的 prompt,并按需传入 negative_promptnum_inference_stepsguidance_scale
  3. 从生成接口响应中读取图片地址,默认路径为 images[0].url
  4. 在同一个沙盒脚本中用 Authorization: Bearer $SILICONFLOW_API_KEY 下载该图片地址;如果接口直接返回 base64,则直接解码保存。
  5. 将最终图片保存到当前 Workdir 的 outputs/ 下,例如 outputs/generated-image.png
  6. 调用 present_artifacts,传入保存后的 outputs 虚拟路径,让前端展示图片产物。
  7. 最终回复简要说明图片已生成,不要把外部临时 URL 当作最终结果展示。

脚本示例

可根据用户需求调整 prompt 和输出文件名:

python
import os
import requests
from pathlib import Path

api_key = os.environ["SILICONFLOW_API_KEY"]
prompt = "根据用户需求整理后的图片提示词"

response = requests.post(
    "https://api.siliconflow.cn/v1/images/generations",
    headers={"Authorization": f"Bearer {api_key}", "Content-Type": "application/json"},
    json={
        "model": "Qwen/Qwen-Image",
        "prompt": prompt,
        "negative_prompt": "",
        "num_inference_steps": 20,
        "guidance_scale": 7.5,
    },
    timeout=120,
)
response.raise_for_status()
image_url = response.json()["images"][0]["url"]

image_response = requests.get(
    image_url,
    headers={"Authorization": f"Bearer {api_key}"},
    timeout=120,
)
image_response.raise_for_status()

output_path = Path("outputs/generated-image.png")
output_path.parent.mkdir(parents=True, exist_ok=True)
output_path.write_bytes(image_response.content)
print(output_path.as_posix())

多模型扩展

如果用户指定其它图片生成模型或兼容接口,可以按该接口的协议先生成图片。只要最终拿到图片 bytes 或 base64,就保存到当前 Workdir 的 outputs/,再调用 present_artifacts 展示。

关键约束

  • 不要把外部生成接口返回的临时 URL 当作最终结果直接展示给用户。
  • 不要调用后端 MinIO 上传工具;图片生成和下载都应在沙盒内完成。
  • 如果 SILICONFLOW_API_KEY 缺失,应明确提示用户需要在 Agent 沙盒环境变量中配置。
  • 保存到 outputs 后必须调用 present_artifacts,否则前端不会自动展示生成图片。

Frequently asked questions

What does the Image Gen AI skill do?

在 Agent 沙盒中生成图片并保存到 outputs。当用户要求生成图片、海报、插画、文生图,或指定 Qwen-Image、其它兼容图片生成接口时使用此技能。

Why use Image Gen on TypingMind?

Because you install it once and use it with any model. Image Gen 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 Image Gen in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/xerrors/Yuxi/tree/main/backend/package/yuxi/agents/skills/buildin/image-gen. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Image Gen?

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 Image Gen?

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

Is the Image Gen AI skill free?

Yes. It is published on GitHub by xerrors 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.
