Claude Code does not support AskUserQuestion in spawned sessions - subagents, agent teams, and workflows — which makes a swarm of agents less efficient in the original implementation. This can be easily fixed with an additional MCP.

Built on a SQLite DB and MCP, blocking until the question is answered, supporting all possible question types, with a CLI or web interface for answers, `ask_human_question` fills the gap in efficient subagent management.
