# UV Suite helper: toggle confirm-mode or change the threshold.
# Used by the /confirm slash command. Extracted into a script so the
# slash command can avoid inline ${...} expansions, which Claude Code's
# permission heuristic flags as obfuscation.
#
# Usage:
#   confirm-helper.sh           # show status
#   confirm-helper.sh status
#   confirm-helper.sh on
#   confirm-helper.sh off
#   confirm-helper.sh <number>  # set threshold
