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 🙏

Readme

Tencent Cloud Service CLS observability for DeepSeek Harness

English | 简体中文

tencentcloud-agentobs-sdk-dsh 是一个 DeepSeek Harness (DSH) 可观测插件,直接将 GenAI trace 数据上报到腾讯云日志服务 (CLS)。

它观察 DSH 原生的 session、agent loop、LLM stream 和 tool 生命周期,将其转换为腾讯云AI Agent可观测规范的 5 层 span 层级模型(entry → agent → step → chat → tool),并通过 tencentcloud-cls-sdk-js 直接上报到 CLS,无需额外部署 OTLP 收集器或 sidecar。

数据模型

DSH session/event + llm/stream
                │
                ▼
      CLS Trace Coordinator
                │
                ▼
    CLS 5-layer span model
    (entry/agent/step/chat/tool)
                │
                ▼
    tencentcloud-cls-sdk-js
                │  Protobuf upload
                ▼
    Tencent Cloud CLS

一次 DSH turn 产生的 trace 结构:

ENTRY
└── AGENT (invoke_agent)
    └── STEP (react round_N)
        ├── CHAT (chat model_name)
        └── TOOL (execute_tool tool_name)

安装

前置依赖

全局安装 DeepSeek Harness CLI:

npm install -g @deepseek-ai/dsh

安装插件

dsh plugin --profile web add tencentcloud-agentobs-sdk-dsh
dsh plugin --profile headless add tencentcloud-agentobs-sdk-dsh
dsh plugin --profile harness add tencentcloud-agentobs-sdk-dsh

注意:安装或更新插件后,需要重启 DSH 服务才能生效。

pnpm 构建脚本问题

pnpm v9+ 默认禁止依赖包运行 install 脚本。如果安装时遇到以下错误:

[ERR_PNPM_IGNORED_BUILDS] Ignored build scripts: [email protected]
Run "pnpm approve-builds" to pick which dependencies should be allowed to run scripts.

在对应 profile 目录执行一次即可(后续安装/更新不再需要):

cd ~/.dsh/profiles/web
echo "enable-scripts=true" >> .npmrc
pnpm install

headless / harness profile 同理,将路径改为 ~/.dsh/profiles/headless 或 ~/.dsh/profiles/harness。

卸载插件

dsh plugin --profile web remove tencentcloud-agentobs-sdk-dsh
dsh plugin --profile headless remove tencentcloud-agentobs-sdk-dsh
dsh plugin --profile harness remove tencentcloud-agentobs-sdk-dsh

配置

环境变量(推荐)

export CLS_ENDPOINT=ap-guangzhou.cls.tencentcs.com
export CLS_TOPIC_ID=your-topic-id
export CLS_SERVICE_NAME=dsh-agent

# 鉴权方式二选一:
# 方式 1(强鉴权):SecretId + SecretKey
export CLS_SECRET_ID=your-secret-id
export CLS_SECRET_KEY=your-secret-key
# 方式 2(免鉴权/弱鉴权):仅提供纯数字 UIN
# export CLS_UIN=your-uin

dsh --profile web

插件配置文件

编辑 $DSH_HOME/profiles/<profile>/cordis.patch.yml:

- id: cls-observability
  config:
    endpoint: ap-guangzhou.cls.tencentcs.com
    topicId: your-topic-id
    # 强鉴权:SecretId + SecretKey
    secretId: your-secret-id
    secretKey: your-secret-key
    # 或免鉴权(弱鉴权):仅提供纯数字 UIN(与 SecretId/SecretKey 二选一)
    # uin: "100000000000"
    serviceName: dsh-agent
    captureContent: true
    batchMaxSize: 32
    flushIntervalMs: 5000
    debug: false

显式插件配置优先于环境变量。

关闭内容捕获

默认情况下,prompts、responses、tool arguments/results 会附加到 span。如需关闭:

export OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=false
dsh --profile web

或在插件配置中设置 captureContent: false。

配置项

| 设置 | 默认值 | 说明 | | --- | --- | --- | | enabled | true | 禁用采集但不卸载插件 | | endpoint | CLS_ENDPOINT | CLS API 接入点 | | topicId | CLS_TOPIC_ID | CLS 日志主题 ID | | secretId | CLS_SECRET_ID | 腾讯云 SecretId(强鉴权,与 uin 二选一) | | secretKey | CLS_SECRET_KEY | 腾讯云 SecretKey(强鉴权,与 uin 二选一) | | uin | CLS_UIN | 免鉴权(弱鉴权)上报的腾讯云 UIN(纯数字,与 SecretId/SecretKey 二选一) | | serviceName | deepseek-harness | 服务名 | | captureContent | true | 捕获 prompts/responses/tool 内容(设为 false 关闭) | | contentMaxChars | 128000 | 单个内容属性最大字符数 | | batchMaxSize | 32 | 每批上报最大 span 数 | | maxBatchBytes | 10485760 | 每批上报最大字节数(10MB)。必须小于 SDK 的 19MB 硬限制,否则整批会在本地被拒 | | maxQueueSize | 2048 | 队列上限,超限丢弃最旧 span | | flushIntervalMs | 5000 | 定时刷新间隔(毫秒) | | retryTimes | 3 | 上报重试次数 | | debug | false | 启用调试日志 |

隐私说明

内容捕获默认开启。源代码、凭证、个人数据等敏感内容可能被发送到 CLS。如需关闭,设置 captureContent: false 或环境变量 OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=false。请确保 CLS 的数据保留和访问控制策略符合安全要求。

兼容性

| 组件 | 支持范围 | | --- | --- | | DeepSeek Harness | >=0.1.0-rc.6 <0.2.0 | | Node.js | >=18.0.0 |
