Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

DeepSeek Harness 视觉能力全家桶:vision_understand 工具(OpenAI 兼容视觉 API,默认免费智谱 GLM-4.6V-Flash,限流自动降级 GLM-4V)+ 粘贴/拖拽/按钮三入口识图

Readme

dsh-vision-tools

DeepSeek Harness(DSH)视觉能力全家桶 —— 让 DeepSeek 纯文本模型"看得见"。

  • vision_understand 工具:调用 OpenAI 兼容视觉大模型 API 理解本地图片(描述画面、识别文字、回答问题),注册为全局工具,所有会话可用。
  • 三入口识图Cmd/Ctrl+V 粘贴截图、拖图到按钮、点按钮选文件 → 图片自动落盘到 $DSH_HOME/pasted-images/ → 输入框填入 请识别这张图片:<路径> → 发送后模型自动调用识图工具。

默认使用智谱 GLM-4.6V-Flash(免费),支持 4 家 provider 切换。被限流时**自动降级到 GLM-4V(glm-4v-flash)**重试,免费模型高峰期也不容易失败。

安装

# 方式一:npm 安装(推荐)
dsh plugin --profile web add dsh-vision-tools

# 方式二:GitHub 安装
dsh plugin --profile web add "github:moon09300731/dsh-vision-tools#main"

重启 dsh web 后生效。

配置(vision_understand 工具需要)

创建 ~/.dsh/vision.env(全局生效,推荐):

VISION_PROVIDER=zhipu        # zhipu | dashscope | siliconflow | openai
VISION_API_KEY=你的APIKey

可选覆盖:

VISION_BASE_URL=https://open.bigmodel.cn/api/paas/v4/chat/completions
VISION_MODEL=glm-4.6v-flash

限流自动降级(可选):

VISION_FALLBACK_MODEL=glm-4v-flash
  • 主模型 VISION_MODEL 被限流(HTTP 429 / 负载过高 / 频率限制等)时,自动降级到 VISION_FALLBACK_MODEL 重试一次
  • 缺省降级模型 = provider 预设模型(zhipuglm-4v-flash,即 v4 版本);主模型与降级模型相同时不会重复请求
  • 仅限流类错误触发降级;密钥无效、参数错误等业务错误不降级,直接报错

| provider | 默认模型 | 说明 | |---|---|---| | zhipu | glm-4.6v-flash | 智谱,免费(128K 上下文,支持思考模式) | | dashscope | qwen-vl-plus | 阿里百炼 | | siliconflow | Qwen/Qwen2.5-VL-7B-Instruct | 硅基流动 | | openai | gpt-4o-mini | OpenAI |

工作区回退:在项目目录放 .dsh-vision.env(同格式),仅该项目生效。配置每次调用实时读取,改完无需重启。

使用

  1. 粘贴:直接 Cmd/Ctrl+V 粘贴剪贴板截图(捕获阶段拦截,优先于 GUI 自身附件处理)
  2. 拖拽:拖图片到输入框左侧的「📷 识图」按钮
  3. 选择:点「📷 识图」按钮选文件

发送后 agent 会自动调用 vision_understand 识别图片。

安全边界

  • 图片会经外部视觉 API 出网(base64 传输),敏感数据请改用本地 OCR(tesseract/paddleocr),或自建内网视觉服务用 VISION_BASE_URL 指向
  • vision.env 含 API Key,不要提交到 git(本仓库 .gitignore 已忽略)
  • 粘贴路由仅监听 DSH 本机端口,图片保存于 $DSH_HOME/pasted-images/

技术说明

⚠️ 依赖约定@deepseek-ai/dsh-tools 是 DSH 宿主运行时自带(bundle 机制提供),本插件不声明为 dependencies。若声明,dsh plugin add 触发 npm install 会在 profile 里装出第二份 dsh-tools,与宿主全局那份形成模块双实例,导致工具执行层 scheduler.prepare 崩溃(Cannot read properties of undefined (reading 'prepare'))。安装后建议确认 profile 的 node_modules/@deepseek-ai/dsh-tools 是符号链接或单实例。

  • 宿主半区:src/index.mjs(Cordis 插件,inject: ['tools', 'webServer']
    • vision_understand 工具经 defineTool 注册(@deepseek-ai/dsh-tools
    • POST /api/vision-paste 路由落盘粘贴图片
  • 浏览器半区:lib/client.bundle.js(手写 __ModuleLoader__ bundle,零构建依赖)
    • conversation.input.left slot 注册「📷 识图」按钮
    • 捕获阶段 paste 监听拦截剪贴板图片
