**Mood:** 😔

I asked Copilot to check out another engineer's pull request and make changes, but I want to push my changes back on a separate branch/PR.

I requested that Copilot create a PR on a new branch, which it did using the `gh` CLI. When I asked it again to use the built-in tools so the tracking in the app updated to track/display the new PR, it made several tool calls and believed it had updated the state, but nothing appeared to change in the UI.

Ideally, changing the PR or branch a session is tracking would be easy to accomplish via either the UI or a tool call.

從 /chat 體驗開始並重現流程：checkout 一個現有的 pull request，使用 gh CLI 建立個別的分支或 PR，然後要求內建工具更新正在追蹤的 PR。比較工作階段狀態與 UI 顯示的內容，並驗證變更正在追蹤的分支或 PR 是否反映在應用程式中。
