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 🙏

v1.0.1

Published

colgrep — semantic code search (ColBERT multi-vector) for DeepSeek Harness. Adds a `colgrep` tool that finds code by meaning, not exact text.

Readme

@hilariouhiss/dsh-colgrep

colgrep(LightOn 的语义代码检索工具:ColBERT 多向量搜索,按“含义”而非“精确文本”找代码)接入 DeepSeek Harness。

本插件以 DSH bundle 插件形式提供一个宿主侧模型工具 colgrep,安装后对 webheadless 等任意 profile 的所有会话生效。

功能

注册一个 colgrep 工具,智能体可用自然语言检索工作区代码,例如:

  • colgrep "error handling for database connections"
  • colgrep "auth" -e "async fn" --include "*.rs"
  • colgrep command:"init" / command:"status" / command:"clear"

工具参数:

| 参数 | 类型 | 说明 | |---|---|---| | query | string(必填) | 自然语言查询 | | command | enum search(默认)/init/status/clear | 检索 / 建索引 / 查状态 / 清索引 | | path | string | 待检索/索引的文件或目录(默认工作区根) | | top_k | integer | 结果数(-k,默认 15) | | pattern | string | 正则预筛(-e,hybrid:先 grep 再语义排序) | | include | string | 只检索匹配 glob 的文件(--include,如 "*.rs") | | code_only | boolean | 只检索代码文件,跳过 md/txt/yaml/json 等 | | no_update | boolean | 跳过自动重建索引,直接检索现有索引 |

行为要点:

  • 结果以 --json 解析后折叠为紧凑可读文本(文件:行-行 [语言, 类型, 名称] (score) + 首行签名),不倾倒整段代码;模型可再 read 具体文件。解析兼容顶层数组与 {results:[...]} 两种 JSON 形状;query 为空或纯空白时返回明确错误。
  • 索引重定位:DSH 文件沙箱禁止写工作区之外,而 colgrep 检索需要写索引锁文件。插件把索引目录重定位到 <工作区>/.colgrep-data(通过 COLGREP_DATA_DIR),使全部写入落在沙箱允许范围内。ColBERT 模型与 ONNX runtime 从 ~/.cache 只读加载,无需联网。
  • 首次检索会自动建立索引(CPU 上大仓库可能需数分钟);可用 command:"init" 显式建索引,no_update:true 走现有索引。

前置要求

  • 已安装 colgrep CLI(cargo install colgrep 或官方预编译二进制),且 colgrep 在 PATH 上。
  • 首次使用前,colgrep 需已下载默认模型 lightonai/LateOn-Code-edgecolgrep "任意查询" 会自动下载;私有模型需 HF_TOKEN,可用 colgrep set-model 切换)。

安装

dsh plugin --profile web add @hilariouhiss/dsh-colgrep

web 换成你的 profile 名(例如 headless)。然后重启 dsh

dsh plugin 会把本包安装进 profile 的 node_modules;因为 package.json 声明了 dsh.bundle.patch,profile 的 bundle 列表会自动追加 @hilariouhiss/dsh-colgrep,重启后插件行自动激活。

验证

  1. 重启后在会话中让模型调用 colgrep,例如“用 colgrep 搜索 error handling 相关代码”。
  2. 或让模型执行 colgrep command:"status",应看到当前工作区的索引状态。

卸载

dsh plugin --profile web remove @hilariouhiss/dsh-colgrep

然后重启 dsh。

开发

pnpm install
pnpm test

结构:

lib/index.js        插件入口:apply(ctx) 注册 colgrep 工具(defineTool)
cordis.patch.yml    bundle patch:插入本插件的宿主行
test/               node:test 单元测试(argv 组装、渲染、execute 管道)

发布(给维护者)

cd dsh-colgrep
pnpm install
pnpm test
npm login       # 首次发布前登录 npm
npm publish     # publishConfig.access 已设为 public

prepublishOnly 会在每次发布前自动运行 npm test;发布新版本前记得递增 package.jsonversion

许可与来源

本插件为 MIT 许可。它只调用外部的 colgrep CLI,未内置 colgrep 源码;colgrep 本身来自 lightonai/next-plaid(© LightOn,其自身许可见上游仓库)。

提示:若日后升级 dsh 后 @deepseek-ai/dsh-tools 的公开 API 发生变化,需同步更新本插件的依赖版本。
