+folder open, edit and preview like any other; chat links to them use absolute paths, and agents
+are told about every listed folder, including the ones that are not repositories. In a new
+worktree, listed folders that are not repositories stay the original folders, shared with the
+project's other threads. Folders the file does not list, and files the project folder holds
+beside the listed folders, are not shown; add the folder to the workspace file to include it.

+The project's setup script runs once in each repository's copy, with `T3CODE_REPO_ROOT` set to the
+checkout the copy came from, so a script can copy files such as `.env` from the original. Each
+copy gets its own terminal. Lines on the setup card say which repository they came from, and the
+card names any repository whose run failed. A script that runs when the thread settles runs the
+same way.

const PULL_REQUEST_LINKING_INSTRUCTIONS = `
When the t3-code MCP server exposes link_pull_request, you must use it to register every pull request you create or work on for this thread. Call link_pull_request with the full PR URL immediately after creating a PR or starting work on an existing PR. For a stack, call it for every layer, not just the current branch or the top PR. This applies when creating or updating PRs through gh, gh stack, another CLI, or the host API: those operations do not register the PRs with this thread. Linking an already-linked PR is safe. Before finishing PR work, call list_thread_pull_requests and link any PR from your work that is missing. Do not link unrelated PRs mentioned only as background. If a linking call fails, report that failure instead of claiming the PR is linked. When asked to monitor, watch, or babysit a PR and watch_pull_request is available, call it and end your turn: T3 Code wakes you when checks finish, someone else comments, or the branch conflicts, so do not poll or run your own watcher. When you hand the work back to the user, call unwatch_pull_request first so the thread returns to their inbox.
