Creating Git worktrees enables parallel development by establishing isolated environments where multiple branches run simultaneously with independent ports and configurations. This skill automates worktree creation under trees/<branch-name>, configures auto-incremented ports, installs dependencies, and starts services—eliminating manual Git commands and port setup.

Yes. Worktrees support parallel environments with automated port allocation and isolated configurations. Each worktree gets its own auto-incremented port, database, and environment files, so multiple branches run concurrently without conflicts or manual port management.

Worktrees eliminate context-switching overhead by maintaining fully configured, independent environments for each branch. Instead of checking out and reconfiguring, you keep multiple branches running simultaneously with separate ports and services, then access them via dedicated URLs.

No. This skill handles all configuration automatically: it allocates ports incrementally, generates environment files, installs dependencies, and starts both server and client services. You only provide the branch name and optional port offset.

Use worktrees when you need to work on multiple branches concurrently—testing a feature while keeping main clean, running isolated testing environments, or maintaining separate parallel development setups. Worktrees preserve your current environment while adding new isolated ones.

After creation, you receive access URLs for the running services plus management instructions for the new worktree, enabling immediate use of the isolated development environment.
