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 🙏

v0.1.4

Published

Configurable subagent profiles with web UI settings, real-time toolcall/token display, and click-to-navigate child sessions.

Readme

yet-another-subagent

npm version

可配置的子代理(subagent)profile 系统,提供单一 subagent 工具 + profile 参数选择,支持 Web UI 设置、实时进度展示(工具调用/token/活动)、子代理树标签页、点击跳转子会话。

架构

单 bundle,三入口(host . + invariant ./invariant + client ./client)。

  • Host 半src/index.ts):
    • 单一 subagent 工具,通过 profile 枚举参数选择 profile(非每 profile 一个工具)
    • 复用官方 spawn provider,支持前台(foreground)和后台(continuable / one-shot)两种模式
    • Profile 状态通过 settings seam 持久化到 $DSH_HOME/settings.yaml
    • RPC CRUD:profiles.list / .add / .update / .remove(专用 /ya-subagent 通道,不共享 /api
    • 两个 session projection:subagentProfile(父会话 childId→profileId 映射 + callId→childId)+ yaSubagentProgress(子会话实时 toolcall/token/活动状态)
  • Client 半src/client/index.ts):
    • settings.section — Profile 编辑页
    • tool.call.toolview(key subagent)— SubagentCard 工具调用卡片
    • conversation.view(id subagent-tree)— SubagentTreeView 子代理树标签页

cordis.patch.yml 只禁用官方 tool-subagent(spawn 路径),保留 tool-subagent-fork(无名称冲突)。

配置

# cordis.patch.yml
- id: tool-subagent
  disabled: true

- insert:
    - id: yet-another-subagent
      name: '@huanlin/dsh-plugin-yet-another-subagent'
      config:
        profiles:
          - id: general
            label: General
            model: { kind: 'auto' }
            persona: { kind: 'inherit' }
            toolFilter: { kind: 'none' }
            maxDepth: 3
            backgroundMode: continuable
            builtin: true
        generalFixed: true

Profile 字段

| 字段 | 类型 | 默认值 | 说明 | |------|------|--------|------| | id | string(小写字母/数字/连字符,1-32 字符) | — | Profile 唯一标识 | | label | string | — | 显示名 | | model.kind | 'auto' | 'manual' | — | auto 继承父代理模型;manual 指定 | | model.provider | string | '' | Provider(仅 manual 时使用) | | model.model | string | '' | 模型 ID(仅 manual 时使用) | | persona.kind | 'inherit' | 'custom' | 'inherit' | inherit 跟随部署人设;custom 自定义 | | persona.text | string | '' | 自定义人设文本(仅 custom 时使用) | | toolFilter.kind | 'none' | 'allow' | 'deny' | 'none' | 工具过滤策略 | | toolFilter.tools | string[] | [] | 过滤工具列表 | | maxDepth | number | 3 | 最大递归深度 | | backgroundMode | 'continuable' | 'one-shot' | 'continuable' | run_in_background: true 时的后台策略 | | builtin | boolean | false | 是否为内置 profile(仅展示用) |

开发

pnpm install          # 安装开发依赖 + zod(唯一运行时 npm 依赖)
pnpm run typecheck    # tsc --noEmit(通过 ../dsh 解析 DSH 源码)
pnpm test             # vitest run
pnpm run build        # tsc + tsdown → lib/index.js, lib/invariant.js, lib/client.js

类型检查

tsconfig.json 继承 ../dsh/tsconfig.base.client.json,通过 pnpm-workspace.yamlpackages/*/* glob 解析 DSH checkout 的源码。需在 ../dsh 存在 DSH checkout 的同级目录下运行。

运行

# 从 npm 安装(推荐):
dsh plugin --profile web add @huanlin/dsh-plugin-yet-another-subagent

# 本地引用(开发热更新)
dsh plugin --profile web add "link:D:/Projects/deepseek-harness/yet-another-subagent"

安装后重启 dsh web 进程,浏览器硬刷新(Ctrl+Shift+R)。

检查

pnpm run typecheck    # 0 errors
pnpm test             # 55 tests passing
pnpm run build        # lib/index.js + lib/invariant.js + lib/client.js

产物验证

  • lib/index.js — Host bundle
  • lib/invariant.js — Invariant companion
  • lib/client.js — Client bundle(CSS-modules inline,d 前缀 hash 防 CSS 类名数字开头)
  • cordis.patch.yml — Bundle patch layer

持久化

Profile 状态通过 DSH settings seam 持久化到 $DSH_HOME/settings.yamlya-subagent 命名空间。cordis.yml 的 profiles 字段是组合 base(首次启动种子),运行时变更通过 scope.replace() 写入用户层。外部 yaml 编辑通过 scope.watch 热重载。

无 settings provider 的无头组装回退到内存状态(仅 cordis.yml 种子,不持久化)。

RPC API

Profile CRUD 走 host 的专用 /ya-subagent 通道(不共享 /api,避免与 Typert gateway 的单拦截器冲突):

| endpoint | payload | result (ok) | |----------|---------|-------------| | profiles.list | {} | { profiles: SubagentProfile[] } | | profiles.add | { profile: SubagentProfile } | { profiles: SubagentProfile[] } | | profiles.update | { profile: SubagentProfile } | { profiles: SubagentProfile[] } | | profiles.remove | { id: string } | { profiles: SubagentProfile[] } | | tools.list | {} | { tools: { name, description }[] } |

URL 形如 POST /ya-subagent/profiles.list。业务错误返回 { ok: false, error: { code: 'internal', message } }

已知限制

  • 旧会话不兼容completed <label> subagent <id> render 格式变更后,旧会话的结果文本无法被 parseResult 匹配,卡片不可点击。仅新会话(host 重启后)正常。
  • yaSubagentProgress stateVersion 2:projection schema 变更(activity 字段 + assistant/chunk fold)需要 host 重启才能生效。
