My/AI/Rule/Work in ghq repos

• Coding agents sometimes start in the wrong working directory. Before writing to a file, creating a branch, or creating a worktree, confirm that the checkout belongs to the repository registered under ghq/root.
• 1. Resolve the current repository root with git rev-parse --show-toplevel.
• 2. Inspect its origin remote and derive the host/owner/repository ghq address.
• 3. Resolve the registered copy with ghq list --full-path --exact <ghq-address>.
• 4. Resolve the real path of ghq root (ghq/root) and the real Git common directory of both the current checkout and the registered copy. git rev-parse --path-format=absolute --git-common-dir prints the common directory.
• 5. Compare real paths and continue when all of these conditions hold:
  • The registered copy is inside ghq root (ghq/root).
  • The current checkout and the registered copy have the same Git common directory.
  • The current repository root is either the registered copy or a linked worktree under its .worktrees/ or .claude/worktrees/ directory, following My/Pref/Dev/Tool/git/Worktree.
• You don't need to tell me about your thought process as you verify you are working in the right directory.
