Feature: Git Worktree Awareness for Claude Code Desktop

Problem

Claude Code Desktop sessions operating in git worktrees lack awareness of their current worktree context. This causes Edit/Write tools to resolve absolute paths against the main repository directory, not the current worktree.

Example:

• Worktree path: D:/repo/.claude/worktrees/feature-branch/
• Main repo path: D:/repo/
• Session cwd correctly shows worktree
• But Edit/Write resolves D:/repo/file.md → main directory, not worktree

Impact

1. AI agents in worktree sessions accidentally modify main branch files
2. Changes appear "staged" on main but are actually 0-byte placeholder files
3. Worktree isolation guarantee is violated

Expected Behavior

Claude Code should:

1. Detect when session is inside a git worktree
2. Use worktree's root as the base for all file operations
3. Optionally respect a git.worktreeStrategy setting in settings.json

Proposed Solution

Add a git.worktreeStrategy option to settings.json:

{
  "git": {
    "worktreeStrategy": "current-branch"
  }
}

Behavior options:

• "current-branch" (recommended): Edit operations target current worktree
• "main-only": Edit operations always target main repository
• "prompt": Prompt user when path ambiguity detected

Environment

• Claude Code Desktop
• Windows 10/11
• Git worktrees
