Auto-collapse finished tool activity after assistant reply

[zerolfl]

What feature would you like to see?

Would it be possible to automatically collapse a completed tool/terminal action block once the assistant has returned the next message?

Right now, long tool traces stay fully expanded and make it hard to scroll back to previous messages. A good UX might be:

• keep tool activity expanded while it is running
• once the assistant posts the next normal reply, auto-collapse that finished block
• show a compact summary like “Used 5 tools / Ran 2 terminal commands”
• allow one-click expand to inspect details again

This would improve readability a lot in long sessions without hiding any information.

Additional information

Example

Current behavior	Expected behavior
Completed tool / terminal activity stays fully expanded.	Completed activity is auto-collapsed after the next assistant reply.

Thanks for the suggestion. I checked the current web chat code, and I could not find any logic that auto-collapses a finished tool/activity block after a later assistant reply.

What I could verify:

• many tool cards are already rendered in a compact form by default, based on each tool's minimal presentation
• CLI output is already shown as a compact card with click-to-open details
• Task child details use a native <details> block, but that is static and not tied to the next assistant message
• summary text like "Used 5 tools / Ran 2 terminal commands" was not found

Relevant code:

• web/src/lib/assistant-runtime.ts:21 - converts each chat block, including tool-call and cli-output, into its own thread message; no collapse/expand metadata is attached
• web/src/components/ToolCard/ToolCard.tsx:309 - inline vs compact rendering is decided from presentation.minimal, task summary, and permission state
• web/src/components/ToolCard/knownTools.tsx:95 - common tool cards like Bash, CodexBash, Read, Edit, and Write are marked minimal: true
• web/src/components/CliOutputBlock.tsx:109 - CLI output renders as a compact card header and opens full content in a dialog
• web/src/components/AssistantChat/messages/ToolMessage.tsx:125 - nested tool children are rendered inline; Task details uses <details> but there is no later-message auto-collapse trigger

So, from the current code, this looks like a real enhancement request rather than an existing option that is just hard to find.
