dsh-turn-collapse

In a multi-turn DSH web chat, every assistant turn renders its reasoning chain and each tool call as separate collapsible rows. When a single turn involves several tool invocations, the interface quickly becomes a wall of tiny panels. dsh-turn-collapse borrows the Codex approach: it groups everything that sits between two visible outputs—the thinking rows and the tool-call nodes—into a single disclosure bar with a triangle toggle. The bar is collapsed by default; one click expands the whole group, while the individual Think rows and ToolRows inside remain independently usable.

The plugin is entirely client-side. It watches the conversation scroll container with a MutationObserver, detects where a node counts as a visible output (text that survives stripping think rows and tool chains), and rebuilds fold groups on every DOM change. Open and close state is persisted per session in localStorage, so it survives re-renders and page reloads. There is no host-side code, no server, and no API surface; the visual style reuses DSH design tokens and matches the native header rows.

It is well suited for anyone running long conversations in DSH and frequently scrolling through dozens of reasoning and tool-call rows. If you prefer the chat stream to show only key outputs and reveal the rest on demand, it cuts visual noise considerably.
