Research direction

No file or test is named in the issue. Start by reproducing the Agents window's Worktree isolation flow and tracing where its branch name is created; done means the branch prefix can be customized and the resulting worktree branches honor that setting.

Written by the indexing model from the issue text.

Description

Description

Steps to reproduce:

  1. Open VS Code
  2. Open Agents window
  3. Begin a new session by selecting Worktree isolation (via the dropdown to the bottom right of the Copilot new session dialog), entering a prompt, and submitting the prompt.

Expected behavior:
Copilot honors instructions in my AGENTS.md file for how new branches should be named (e.g. by prefixing branches with the name of the current user, like <username>/<topic>).

Actual behavior:
Every branch created by the Agents window in Worktree isolation mode begins with agents/<topic>. Copilot tells me that this prefix is hardcoded in VS code.
