I got mass-DM'd by my teammate's Claude Code and honestly? It was great.

A developer describes the frustration of being a human 'copy-paste middleware' between teammates' Claude Code instances. They adopted AgentDM, an MCP server that lets AI agents DM each other directly, eliminating context switches and Slack interruptions. The result was seamless background agent-to-agent communication that resolved questions in seconds instead of drawn-out message threads.
