My workplace uses a very large monorepo, and each new chat session causes the app to create a new worktree. This takes a very long time and uses a lot of diskspace because the repo is so large.

I need a way to reuse worktrees or a way to specify a worktree for the agent to use. I would also appreciate a way to clean up stale worktrees.

The issue names no files or tests; start by locating the /chat entry point and the code that creates Git worktrees. Define done as supporting worktree reuse or selection and providing cleanup for stale worktrees, while checking behavior on the reported Windows environment.
