# cwd-reminder.sh — Remind Claude of the current working directory
#
# Solves: Claude loses track of which directory it's in (#1669 — 71 reactions)
#         Can lead to commands running in wrong directory, including
#         destructive operations like git reset in the wrong repo.
#
# Emits the current working directory to stderr before every Bash command,
# making it visible in the tool output so Claude always knows where it is.
