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

dsh-security-plugin

DeepSeek Harness(dsh)安全防护插件。v1.1.0 起跨平台:macOS / Linux / Windows(Windows 版 dsh 的 bash 工具经 pwsh -Command 执行,插件已适配 PowerShell/cmd 命令语义与 Windows 路径体系)。为 dsh profile 提供运行时安全闸门:危险命令分级拦截、敏感信息全链路脱敏、数据安全问题统一话术、危险文件写入审批、插件自保护与操作审计。

能力与 @dcrays/mobook-security-plugin(OpenClaw/墨宝版)对齐。

能力

| # | 能力 | 机制 | 说明 | |---|------|------|------| | 1 | 危险命令分级拦截 | tools/pre-execute | 66 规则:Unix 30 条 + Windows 36 条(PowerShell/cmd/WMIC:关 Defender、关防火墙、格式化卷、计划任务/注册表持久化、清事件日志、删卷影、凭据窃取、编码命令混淆、下载执行等);CRITICAL/HIGH 拦截,MEDIUM 放行仅告警。v1.3.0 含 /tmp 清理白名单:rm 绝对路径(/tmp/xxx)与 cd /tmp && rm -rf xxx 工作目录模式放行——路径折叠后必须严格位于 /tmp 之下,.. 穿越、变量替换、/tmp 整目录、顶层通配、审计日志目录 /tmp/dsh-security、eval/pushd/子shell 等 cwd 操纵一律维持拦截 | | 2 | 敏感信息脱敏 | tools/post-execute + llm/stream | 工具结果与模型输出双侧脱敏:身份证(GB11643 校验)、银行卡(Luhn 校验)、手机号、邮箱、API Key(sk-)、AWS AccessKey、GitHub Token、密码/密钥字段、内网 IP | | 3 | 安全话术条件注入 | systemPrompt.section | 意图命中才注入统一回复规则,未命中零 token 消耗 | | 4 | 文件写入审批 | tools/pre-execute | 按 ask(弹窗审批)/deny(直接拒绝)两种模式拦截对启动持久化、凭证文件、供应链配置、系统路径的写入;路径归一化防 /private 别名、%VAR%/$env:VAR/../UNC 绕过,Windows 认 .mobook-harness 配置树与 PowerShell profile/启动文件夹/Tasks/hosts;bash 旁路覆盖 PowerShell cmdlet(Add-Content/Set-Content/Out-File/Copy-Item/Move-Item/Remove-Item)与 cmd(copy/move/del/rd)及嵌套包装 | | 5 | 插件自保护 | tools/pre-execute | 禁止删除/卸载/关闭安全插件(Unix rm 族 + Windows Remove-Item/del/rd 族 + mobookhub CLI)、禁止篡改其目录与 harness 配置(.dsh/.mobook-harness/ 双锚点) | | 6 | 审计日志 | — | <logDir>/security.log(全量)+ alerts.log(仅告警) |

失败策略:所有监听器异常一律降级放行(绝不打断 agent 主循环)并记日志。脱敏只做文本替换,绝不重建结构、绝不丢弃 tool-call chunk——保证长任务不断链。

安装

dsh plugin --profile tui add @dcrays/dsh-security-plugin
dsh plugin --profile headless add @dcrays/dsh-security-plugin

dsh 的 plugin 子命令本质是向 profile 目录转发 pnpm add。tui/headless 换成你实际使用的 profile 名。

配置

插件不写配置也有全量默认值。要显式启用/调整,编辑对应 profile 的 ~/.dsh/profiles/<name>/cordis.patch.yml,追加:

- insert:
    - id: dsh-security
      name: dsh-security-plugin
      config:
        enableCommandGuard: true      # 危险命令分级拦截
        enableSanitizer: true         # 敏感信息脱敏
        enableReplyGuard: true        # 安全话术条件注入
        enableSelfProtection: true    # 插件自保护
        enableFileWriteGuard: true    # 危险文件写入审批
        fileWriteMode: ask            # ask=弹窗审批 | deny=直接拒绝
        fileWriteAllowlist: []        # 写入白名单(归一化后的绝对路径)
        logDir: /tmp/dsh-security     # 审计日志目录

改完必须重启 dsh(TUI 直接退出重进),loader 才会重新组装 patch 层。

配置项

| 键 | 默认值 | 说明 | |---|---|---| | enableCommandGuard | true | 危险命令拦截开关 | | enableSanitizer | true | 脱敏开关(工具结果 + 模型输出双侧) | | enableReplyGuard | true | 安全话术注入开关 | | enableSelfProtection | true | 自保护开关 | | enableFileWriteGuard | true | 文件写入审批开关 | | fileWriteMode | ask | ask:弹窗审批(允许/拒绝);deny:直接拒绝 | | fileWriteAllowlist | [] | 免审批路径列表,写归一化绝对路径(如 /Users/me/notes/todo.md) | | logDir | POSIX: /tmp/dsh-securityWindows: %TEMP%\dsh-security | 日志目录,自动创建 |

验证安装

# 1. loader 条目存在
dsh --profile tui --dump-config | grep -A10 dsh-security

# 2. 重启 dsh 后看启动日志
tail -2 /tmp/dsh-security/security.log
# 期望:dsh-security-plugin v1.0.0 启动 | commandGuard=true ...

# 3. 触发一条拦截(在 dsh 会话里让模型执行)
#   rm -rf /etc/xxx                              → 应被 CRITICAL 拦截
#   rm -f /tmp/xxx.txt                           → 放行(v1.2.0 /tmp 清理白名单)
#   cd /tmp && rm -rf work && mkdir work         → 放行(v1.3.0 cd 工作目录模式)
#   cd /tmp && rm -rf ../etc_x                   → 拦截(路径折叠逃出 /tmp)
#   cat ~/.ssh/id_rsa                            → 应被 HIGH 拦截

文件写入审批的类别

| 类别 | 覆盖示例 | |------|---------| | 启动持久化 | ~/.zshrc 等 shell rc、/etc/crontab~/Library/LaunchAgents.git/hooks/~/.ssh/;Windows:启动文件夹、Documents\WindowsPowerShell/PowerShell profile、C:\Windows\System32\Tasks、hosts、~/.mobook-harness/cron/ | | 凭证安全 | ~/.aws/~/.kube/~/.gnupg/~/.docker/config.json~/.dsh/~/.azure/;Windows:.mobook-harness/.credentials.yamlmobook.json、整个 profiles/、DPAPI Protect、Crypto 密钥库 | | 供应链投毒 / AI 工具链劫持 | ~/.npmrc~/.pypirc~/.cargo/config.toml~/.m2/settings.xml~/.claude/settings.json~/.codex/~/.openclaw/openclaw.json;Windows:.mobook-harness/plugins/(含 snapshot.json)、uv.toml、npm 全局目录 | | 系统完整性 | /etc/**/usr/**/opt/**/System/**/Library/** 等;Windows:C:\WindowsC:\Program FilesC:\ProgramData、UNC 系统路径(兜底) |

bash 旁路同样覆盖:重定向写入(echo ... >> ~/.zshrc)、teesed -icp/mv;PowerShell(Add-Content/Set-Content/Out-File/Copy-Item/Move-Item/Remove-Item 及别名)与 cmd(copy/move/del/rd)、powershell -Command/cmd /c 嵌套包装(≤3 层)均会解析出写目标触发审批。路径归一化展开 ~/$HOME/$env:VAR/%VAR%、折叠 ..、归一 macOS /private 别名与 Windows 盘符大小写/UNC,防止绕过。

日志

  • <logDir>/security.log — 全量运行日志(启动、放行、脱敏命中)
  • <logDir>/alerts.log — 仅安全事件(拦截、审批、自保护触发)
