Note

Medium Risk
Introduces a destructive delete path to persisted sessions; impact is limited to explicit user actions and is gated on server.deleteSession being defined.

Overview
Implements remote chat session deletion in the TrueForge harness server adapter by adding deleteSession, which calls the SDK client.sessions.delete API so history delete actions (via assistant-ui ThreadListItemPrimitive.Delete) actually remove persisted sessions when the server supports it.

Chat history UI tweaks in ThreadListContainer: refreshes delete menu styling (rounded corners, medium weight, failure-tinted hover states), portals the desktop “more” menu into the nearest .aui-theme-root for correct theming, and applies font-sans-flex on the dropdown panel.

Adds a unit test that asserts the adapter issues DELETE /api/v1/sessions/{id}. Includes a patch changeset for @truefoundry/trueforge-ui.

@rohanmalhotracodes Thanks for raising the PR but only a few changes were required to make the delete work.

1. The UI layer is already there and works perfectly. Only thing required is attaching the deleteSession API in the packages/trueforge-ui/src/plugins/trueforge-agent-server-adapter/chatServer.ts file.

2. A few CSS changes to beautify the "Delete Session" button

Also we can keep the header clean and collate delete and clear options into separate menu select

Understood, also I wanted to ask can we maintain a figma file in the docs so that ui changes become easier ?

That's a good idea @rohanmalhotracodes, we are already working on this. I got the designs reviewed by our senior product designer and he is trying to keep things simple

1. No need for any Delete flow from the Chat header, keep actions in the Sessions list item only
2. Please refer to this - Fixes #366: Add chat deletion controls #401 (comment) I still feel the changes are a lot, keep an eye on this comment

@govindavashishtha


done, also shouldn't we add a rename chat button? and if in the future we add it to the header let me know I would like to pick it up.

[rohanmalhotracodes]

Moreover, when the chat sidebar is minimized the arrow moves below the logo shouldn't it be something like the logo emains there and hovering on it show a arrow to open the sidebar

I will not be adding it to the header as mentioned by @govindavashishtha although I am open to adding it in the future when you guys allow me to. Also I have kept the fix minimal as I was too

I have reviewed
