Hcom Agent Messaging

This connects AI coding agents running in separate terminals so they can message each other, watch file edits, and spawn new agents in real time. You'd use it when you want Claude in one terminal to hand off context to Gemini in another, or have a reviewer agent automatically check another agent's work and send feedback. The hook system is automatic for Claude, Gemini, Codex, and others. Setup is straightforward but watch out for the gotchas around threading and cleanup, especially if you're writing multi-agent scripts. The reference patterns are actually helpful. It's solving a real coordination problem if you're running multiple agents, though you'll spend some time learning the event system and intent flags.
