dsh-interrupt-button

dsh-interrupt-button

A green interrupt button beside the DeepSeek Harness send box. While the
agent is running, one click silently interrupts it in the background —
no simulated user message appears in the transcript. The agent then stops its
current work, summarizes what it has done as an assistant message, and asks
you: "Do you have any new requirements or suggestions?" — waits for your
reply, and merges your new requirements with the old ones before continuing.

When the agent is idle, clicking the button opens a dialog where you can
customize the interrupt prompt (the model-facing instruction sent on the
next interrupt), save it, or send it immediately.

Features

• 🟢 Green button in the composer tool row, right beside the send button
• ⏸ Strong pause: aborts the active turn (model request / tool calls),
  kills background jobs and terminals owned by the agent, interrupts child
  agents, and disarms an armed goal so automatic continuation stops; queued
  messages are preserved (keepInbox)
• 💬 The agent replies as an assistant message: stops, summarizes its
  progress in a few sentences, and asks for your new requirements
• ✎ Customizable interrupt prompt: edit the model-facing instruction in a
  dialog (available when nothing is active); save it, or save & send
  immediately
• 🌗 Theme-aware dialog (light/dark via DSH theme tokens)

Install

dsh plugin --profile web add guo-ziao/dsh-interrupt-button

Or via npm:

dsh plugin --profile web add dsh-interrupt-button

How it works

The host half registers one loopback HTTP route (POST /dsh-interrupt-button/interrupt).
On press it performs a strong pause — agent.cancel({ kind: 'user' }, { keepInbox: true })
to abort the active turn, jobs.kill / terminals.kill for background work,
subagents.interrupt for child agents, and goals.disarm for an armed goal —
then agent.steer(...) with a plugin-source (notice form) message, so the
transcript shows a system-style context row instead of a fake user message and
the model produces the short summary and the question itself. When nothing is
active, the handler returns nothingActive and the browser half opens the
prompt editor instead.

Default interrupt prompt

The following instruction is sent to the agent when you have not customized
it (short thinking, brief summary, and the exact closing question):

【用户按下了“打断”按钮】
用户刚刚按下了打断按钮，立即执行以下操作，不得继续当前任务：

1. 立即停止并结束当前一切工作：停止思考、停止工具调用、停止后台任务。
2. 用不超过三句话简短总结你到目前为止的进展，只讲结果，不展开过程。
3. 回复的最后一句必须原样是：“你有什么新的要求和建议吗？”
4. 然后停下等待用户回复；用户给出新要求或建议后，将新要求与旧要求融合，再继续工作。
   不要长篇分析，直接简洁回复。
