dsh-global-task-list

A global task library for the DeepSeek Harness: five model-facing CRUD tools, a persistent browser panel, subagent job status synchronization, and a generative-UI surface renderer. Tasks persist across sessions in a storageDomain unit and survive restarts.

> 全局任务列表插件：为 DeepSeek Harness 提供一个跨会话持久化的任务库，附右下角常驻面板（轨迹等非对话界面自动隐藏）。主 agent 用 task_add 创建任务（带描述与进度），spawn 子 agent 后关联 jobId 自动同步终态；面板支持手动改状态、删除、拆分，并实时（SSE）刷新。任务可携带 surface 结构化文档渲染生成式 UI（进度条、时间线、表格、DAG 等）。

What it does

• Global task library — task_add / task_list / task_update / task_delete model tools over a cross-session storageDomain unit (task_ui). Tasks carry a title, status (pending / running / done / blocked / failed), description, parentId, dependsOn, an optional progress ({ text, percent? }), and an optional surface document.
• Persistent panel — a bottom-right floating panel (mounted in the session-scoped conversation.input.dock slot) subscribes to a Server-Sent Events channel (/task-ui/events) and refreshes on every task change, letting the user change status, delete (with confirmation), and trigger a generative split loop. Styled with --dsw-* theme tokens and localized zh/en. It disappears on non-conversation views (e.g. trajectory).
• Subagent job sync — a task linked to a background job via task_update(id, { jobId }) auto-advances its terminal status through the JOB_STATUS_MAP (completed→done, failed→failed, killed→blocked). Tasks are created explicitly by the master agent, never auto-registered from arbitrary background jobs.
• Generative UI surface — a task's surface field renders a whitelisted, recursive component tree: section, metric, statusBadge, progress, table, list, timeline, dag, disclosure.

Install

Installing from npm is the recommended path — the package ships prebuilt lib/, so no build step runs at install time. The GitHub alternative pulls source and builds on install (see below).

# npm (recommended, prebuilt — no build step at install)
dsh plugin --profile web add dsh-global-task-list

# GitHub (alternative: source + prepare build)
dsh plugin --profile web add github:sgzxs/dsh-global-task-list#v0.1.4

The package declares dsh.bundle, so dsh adds it to the profile's bundles automatically. Requires a DSH installation with @deepseek-ai/dsh-base and the client surface (dsh-web-app) present.

GitHub install: allowBuilds

Installing from GitHub pulls source, so pnpm must run the package's prepare script to build lib/. pnpm blocks that by default for git-hosted packages, and its allowBuilds key matches the exact commit (a package-name-only entry does not match — see pnpm#12367). The first add therefore fails with an ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED message that prints the exact key to allow. Copy that exact key into the profile's pnpm-workspace.yaml, then re-run:

allowBuilds:
  dsh-global-task-list@git+https://github.com/sgzxs/dsh-global-task-list.git#<commit>: true

Pin a tag (e.g. #v0.1.4) in the install command so the commit hash — and therefore the allowBuilds key — stays stable.

Requirements

• DeepSeek Harness (@deepseek-ai/dsh), version compatible with 0.1.0-rc.6.
• The Host half resolves @deepseek-ai/dsh-tools, @deepseek-ai/dsh-llm, @deepseek-ai/dsh-storage-domain, and zod from the profile's node_modules.
• The client bundle is prebuilt (lib/client.js) and ships with the package; no build step runs at install time.

Build (development)

npm install
npm run build:host    # tsdown bundles src/index.ts → lib/index.js
npm run build:client  # tsdown bundles src/client → lib/client.js

Both halves are TypeScript: the Host half (src/index.ts) compiles to plain ESM, and the client half (TSX) compiles with CSS Modules (lightningcss) into a __ModuleLoader__ closure-factory bundle.

Model Experience

Request context and condition

The package contributes five model-facing tools to the agent's tool catalog.

#### What the model sees

• taskui_probe — reports the plugin's host-alive status and current task count.
• task_list — lists every task as - [status] title (id, job=...).
• task_add(title, description?, parentId?, dependsOn?, surface?, progress?) — creates a task (initial pending).
• task_update(id, title?/status?/description?/parentId?/dependsOn?/surface?/progress?/jobId?) — patches one task; progress is { text, percent? }, surface accepts a structured generative-UI document, and jobId links the task to a background job for terminal-status sync.
• task_delete(id) — deletes one task.

The surface document is a recursive, whitelisted component tree (section / metric / statusBadge / progress / table / list / timeline / dag / disclosure) rendered by the browser panel. Unknown kinds are ignored by the renderer; the Host stores the document as opaque JSON.

#### Token effect

Five tool schemas plus their descriptions are injected into the system-prompt tool catalog. Fixed cost; no per-task or data-dependent prompt growth.

#### KV Cache effect

Independent of the agent's request-context assembly. The tool schemas are static, so the prompt prefix is stable across requests; task-list content does not enter the prompt. A plugin version change replaces the tool schemas and invalidates reuse.

Known Limitations and Deferred Work

• No graph layout — the dag surface renders nodes as chips plus an edges list, not a positioned graph.
• Surface is opaque — the Host stores surface as unvalidated JSON (z.record); malformed kinds fall back to "ignored" in the renderer rather than a load-time error.
• sync-profile.mjs is a local dev helper — it is not published (excluded via files); use dsh plugin add for installation.

Acknowledgements

Inspired by HomeRail — its generative-UI (A2UI) idea of "the agent emits a bounded, whitelisted component tree that a host renders into a glanceable view" shaped this plugin's surface document and component catalog (section / metric / statusBadge / progress / table / list / timeline / dag / disclosure), as well as the principle of preferring built-in rendering over dumping raw logs.
