# clear-command-confirm-guard.sh — Block accidental /clear command
#
# Solves: /clear destroys all conversation context with zero
#         confirmation. Prefix matching means /c + Enter can
#         accidentally trigger /clear instead of /commit or /compact (#40931).
#
# How it works: Blocks /clear entirely. Use /compact to reduce
#   context without losing it.
#
# TRIGGER: UserPromptSubmit
