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 plugin: first-class Git workflow tools for the model — repo status, diffs, commit creation with validated messages, recent history, and branches. No bare-shell git calls; every invocation runs through the harness shell executor (sandbox +

Readme

dsh-plugin-git-workflow

DeepSeek Harness 插件:给模型提供一等公民的 Git 工作流工具 —— 仓库状态、diff、规范 commit、历史、分支,不再需要裸 bash/pwsh 手搓 git。

背景

DSH 内置没有任何 git 工具。模型只能通过 bash/pwsh 调用 git,输出原始、易错、难解析,还容易把用户输入拼进 shell 命令(注入风险)。这个插件把 Git 变成结构化、安全、可解析的工具集。

工具

| 工具 | 作用 | |---|---| | git_status | 分支、upstream、ahead/behind、staged / unstaged / untracked / conflicts 清单(porcelain 解析) | | git_diff | 工作区 diff 或 staged diff(--cached),支持 --stat 摘要、路径过滤、行数截断 | | git_log | 最近提交(hash/日期/subject),可选 files 列出每个提交改动的文件 | | git_commit | 校验 message 后 git add(可选路径)+ git commit -m;清晰报出 "nothing to commit" | | git_branch | 本地分支列表,标记当前分支 |

安装

dsh plugin --profile web add dsh-plugin-git-workflow

挂载(profile cordis.patch.yml 或 agent preset):

- insert:
    - id: git-workflow
      name: dsh-plugin-git-workflow

使用

git_status                        # 看当前仓库状态
git_diff                          # 看未暂存改动
git_diff staged: true             # 看已暂存改动
git_commit message: "fix: ..."    # 提交(全部已暂存内容)
git_commit message: "feat: ..." paths: ["src/a.js"]   # 先 add 再提交
git_log count: 20 files: true     # 最近 20 条 + 改动文件
git_branch                        # 分支列表

所有工具都接受 workdir(默认会话工作目录,相对路径按会话目录解析)。

设计说明

  • 零 shell 注入:所有 git 调用经 harness 的 shell 执行器(ctx.shell)运行,参数逐个引号转义,用户输入不可能被解释为 shell 语法——同时继承沙箱与审批语义(read-only 会话无法 commit)。
  • 输入校验:commit message 非空、≤2000 字符、无 NUL;路径拒绝绝对路径与 .. 穿越(反斜杠归一化后检查),保证不越出仓库。
  • 纯逻辑可单测:解析(porcelain / diff-stat / log / branch)与校验全部在 lib/git.js 纯函数里,npm test 零依赖。
  • 结构化输出:每个工具返回带 schema 的 JSON,render 输出可读文本;失败返回 { ok:false, exitCode, message } 而非裸报错。

诚实边界

  • git 调用经 harness 的 shell 执行器(ctx.shell)运行,继承沙箱与审批语义;路径校验是词法级的,符号链接/工作树外路径依赖 git 自身约束。read-only 模式下写操作(git add / commit)会被沙箱拒绝。
  • commit 需要仓库已配置 user.name/user.email(git 自身报错会透传)。
  • git_logfiles 解析假设 --name-status 输出格式;非常规编码的路径可能显示不完整。
  • 不含 push / pull / rebase 等网络操作(后续版本可加,需审批语义配合)。

本地开发

cd plugins/dsh-plugin-git-workflow
npm test          # node --test,零依赖
