dsh-thinking-collapse
English | 中文
Codex-style live activity collapse for the DeepSeek Harness Web chat view.
Verified with @deepseek-ai/dsh@0.1.0-rc.6.
What it does
The plugin replaces the chat view's assistant-step and tool-call renderers so each assistant turn has one outer activity row.
While the turn is still running — thoughts are streaming, or ordinary tools in this turn are still running, and no visible answer has appeared yet — the outer row stays open. Inner thoughts keep the DSH Think row: Think icon, title Think, first-line preview when collapsed, and the latest line while streaming. Official tool cards appear in time order. The outer title ticks as compact elapsed time, for example 已处理 2s.
When the turn settles — the answer appears, or every tool in the turn has finished — the outer row folds to a duration title such as 耗时 2秒. Expanding it still does not preview thoughts in the outer header; each inner Think row stays collapsed until you open it.

Behavior
- One outer activity row per turn. All thoughts and ordinary tool calls in that turn go inside it.
- Inner thoughts keep the DSH Think row. They stay collapsed by default, including while streaming, and never show an inner elapsed title.
- Duration starts when thinking or the first tool in the turn starts, and continues until the last tool result or the answer appears. Time keeps counting while tools are still running.
- Ordinary tools (bash, read, search, web, todo, and similar) are drawn inside the outer activity body from the start of the stream. They do not first appear as standalone chat rows and then get absorbed.
ask_user_question and approval prompts stay in the editor or their original chat seat.- A tools-only turn still gets an activity row. When history cannot recover a duration, the title is
工具调用 / Tool calls; when there was thinking but no duration, it is 思考过程 / Thoughts.
- The outer collapsed row uses a trailing chevron and a header divider, without a thinking icon. Inner thoughts keep the DSH Think icon.
- Inner Think bodies match the upstream plain think text. Answers reuse DSH
MarkdownText. Tools reuse the official tool.call.toolview cards, including Markdown, images, unknown blocks, file mentions, and interrupted markers.
- The assistant answer stays outside the activity row.
- The trajectory view, model requests, and session log are unchanged.
