Branch Name

Derive from user input (ask if missing). Default format: <type>/<kebab-description> using conventional commit types (feat when ambiguous). Check git branch first — if the repo uses a different convention (e.g., feature/JIRA-123-desc), match it.

Show the derived name before proceeding.

Worktree Location

{repo_root}/.claude/worktrees/{branch_slug} where branch_slug replaces / with -
repo_root = git rev-parse --show-toplevel
Ensure .claude/worktrees/ exists and is in .gitignore

Base Branch

Branch from the latest remote default, not from HEAD — HEAD can be stale or on an unrelated branch, silently seeding the worktree with the wrong history.
