What problem does it solve? When multiple agents or developers work on the same repository simultaneously, they risk branch conflicts, duplicated work, and clobbering each other's changes. This Skill enforces a disciplined workflow where every task gets its own Git worktree and branch created from the latest origin/main, so parallel work never collides. ## Core Features & Use Cases - Isolated Worktree Creation: Creates a dedicated worktree and uniquely named branch from origin/main for every new task, with naming conventions and collision handling. - Scope Conflict Detection: Checks open PRs via gh pr list and their changed files before starting, stopping work if another PR touches the same files. - Harness-Aware Behavior: Adapts steps for Claude Code and Cursor-managed worktrees, skipping manual worktree commands when the harness manages them. - Use Case: An agent assigned to add user authentication runs this Skill first, gets a fresh worktree on branch agent/user-auth-0816a, verifies no open PR touches auth files, installs dependencies, and begins coding without interfering with other agents. ## Quick Start Start a new task by creating an isolated Git worktree branched from origin/main before writing any code.
