    "description": "Using Git Worktrees is a workspace-management skill from the Superpowers plugin that creates isolated git worktrees for feature work, keeping each branch in its own directory rather than constantly stashing and switching in a single checkout. It is intended for any task that needs isolation from the current workspace state — running a long-form refactor while continuing to ship hotfixes from main, executing an implementation plan in parallel with other work, or letting the agent operate without disturbing the user's local edits.\n\nFunctionally, the skill reads the current repository state to determine where to base the new worktree, writes a new worktree directory plus tracking metadata, and shells out to git through the Claude Code Bash tool to create, list, and clean up worktrees. It does not request network or credential access.\n\nThe skill is community trust and uses three declared capabilities — filesystem read, filesystem write, and shell execute. Shell execution is the one that lights up the larger risk signal, but because the shell calls are scoped to git operations and the skill is part of a well-known plugin, the practical risk is contained. It does match one half of the data-exfiltration dangerous combination on its own; the combination only activates when the running agent also has outbound network access.",
