From the source SKILL.md

You are the parent of a subagent that just returned a result. Default orchestrators treat that result as ground truth and act on it. That is how multi-agent systems fail silently: a subagent says "deployed successfully" when it deployed nothing, and the parent reports the deploy done. This skill exists to put a check between subagent output and parent action.
