# power-tools UserPromptSubmit hook (intents 66, 66b, 187, 246). Emits the
# PowerTools mandate, one recommendation line per present tool, as
# hookSpecificOutput. Silent no-op (exit 0) when no power tool is present or
# anything goes wrong. It parses no prompt: the mandate depends on tool presence
# alone, so there is nothing to gate on prompt triviality. Intent 246 removed the
# qmd hit search this hook used to run first.
