claude -w hangs indefinitely

Description

Running claude -w <worktree-name> causes a complete hang with no output. The CLI never responds or produces any error message.

Environment

• Claude Code version: 2.1.69
• OS: macOS (Darwin 25.3.0)
• Shell: zsh

Steps to reproduce

1. Run claude -w some-worktree-name
2. Observe complete hang — no output, no error

Expected behavior

Claude Code should either enter the worktree and start a session, or produce an error message if the worktree doesn't exist.

Workaround

Manually creating a worktree and running claude from within it works fine:

git worktree add ../some-worktree-name some-branch
cd ../some-worktree-name
claude
