A developer encountered issues with multi-agent AI systems, specifically with Claude Code, where sub-agents appeared unresponsive. The core problem stemmed from how agents communicate with their parent processes. One agent sent its response as plain text, which was logged to its own transcript but not directly to the parent. Another agent used a messaging tool successfully, but its message was only delivered after the parent process completed its current turn, leading to a perceived silence. To address this, the developer implemented three rules: prioritizing file writes for results over messages, always reading agent transcripts before declaring them unresponsive, and using synchronous sub-agent calls for immediate feedback instead of asynchronous teammate-style agents.
