dsh-subagent-max

English | 中文

Multi-panel live subagent viewer for DeepSeek Harness (DSH), plus a subagent_with_model tool for per-call model/provider override.

Screenshots

Subagents tab — a card grid grouped into active / inactive and sorted by last activity.

Floating viewer panel — a draggable panel streaming a subagent's live output: task, reasoning, tool calls, and text.

A two-face DSH plugin:

• Host face (lib/index.js) — a Cordis plugin that registers the subagent_with_model tool, a thin wrapper over ctx.subagents that forwards model / provider into the child's agentOptions.
• Client face (lib/client.js) — a Web UI that renders every subagent as a draggable, resizable floating panel with live token-by-token output, plus a Subagents tab with a card grid.

Features

• Per-call model / provider override — delegate to a subagent and pick its model explicitly.
• Multi-panel live viewer — open several subagent panels at once; each streams output in real time.
• Rich block rendering — prompt block, reasoning (think) blocks, tool-call cards with input/output, streaming shimmer, markdown.
• Subagents tab — card grid grouped into active / inactive and sorted by last activity; shows model, tokens, steps, context % and relative update time.
• Drag to pop out — drag a card onto the canvas to open its panel exactly where you drop it (with a ghost preview).
• Notifications — side-top toasts when a subagent starts or receives a message.
• i18n — zh / en, switchable from DSH settings.

Known Limitations

• Model display is derived from the session's request/header; it can be absent for some children.
• Last-activity time is tracked client-side and cached in localStorage; the first open after a fresh load may fall back to the session's updatedAt.
• Client UI targets the web platform only.

Development

pnpm install
node --check lib/index.js lib/client.js
