# no-ask-human.sh — Block commands that require human input
# ================================================================
# PURPOSE:
#   During autonomous operation, Claude Code should never run
#   commands that wait for human input (read, select, interactive
#   git rebase, etc.). These cause the session to hang indefinitely.

# TRIGGER: PreToolUse  MATCHER: "Bash"
