230230List directories in `sparsePaths`, not individual files. Root-level files like `package.json`, `tsconfig.base.json`, and lock files are always checked out alongside the directories you list. Root-level directories are not, so include `.claude` in the list if you want the repository root's `.claude/settings.json` or `.claude/rules/` available inside the worktree. For project skills, agents, and commands, see [What worktrees share with the main checkout](/docs/en/worktrees#what-worktrees-share-with-the-main-checkout).

232Sparse checkout requires git to enable `extensions.worktreeConfig` in the repository's shared `.git/config` while a sparse worktree exists. Claude Code removes that entry after the last worktree is removed, but only if Claude Code added it. It never removes a value you set yourself. Before v2.1.207, the entry remained after the last worktree was removed, and go-git-based tools such as `tea` failed to open the repository until you ran `git config --unset extensions.worktreeConfig`.
