branch-setup

What problem does it solve?

Creates an isolated git worktree for a story before implementation begins, protecting the main branch from in-progress work and enabling reproducible testing environments.

Core Features & Use Cases

• Isolated worktree creation on feature/[story-slug] branch to keep work separate from the main line.
• Verifies that the worktree directory is git-ignored and updates .gitignore if needed.
• Installs dependencies appropriate to the project's tech stack (npm, cargo, pip, poetry, etc.).
• Runs a clean baseline test suite to ensure a ready state before coding begins.
• Aligns with DoR sign-off and provides a smooth handoff to the implementation plan.

Quick Start

Invoke the branch-setup skill after DoR sign-off to create a new feature worktree, install dependencies, and verify a clean baseline.
