Claude Code adds worktree baseRef setting

This is a real quality-of-life fix for agentic coding, but it’s still opinionated toward trunk-based workflows. Teams running a long-lived integration branch get a partial answer, not the branch-aware worktree control they actually want.

• –`fresh` restores the old default of branching from `origin/<default>`, while `head` preserves local unpushed commits in new worktrees
• –That makes Claude Code safer for multi-step refactors where the current branch already contains important work
• –The gap is obvious for orgs that treat `dev` as the integration branch; there’s still no explicit `origin/dev` option
• –This looks like Anthropic tightening workflow ergonomics around worktrees rather than rethinking the underlying branch model
• –Net effect: better for solo devs and trunk-based teams, still awkward for larger branch-heavy setups
