Claude Code Hook Comms (HCOM)

hcom connects independent coding agents across terminals and machines.

Checked 2026-10-31

hcom connects independent coding agents across terminals and machines. Start an agent with hcom in front, and agents can message each other in real time, observe what others are doing and launch more agents. The README says messages arrive mid-turn after tool calls or wake an idle agent, and you can watch status, transcripts, file edits and token use. It lists Claude, Codex, OpenCode, Grok, Hermes, Cursor, Gemini, Copilot and others, with hooks for automatic delivery and hcom listen for tools without them. Install is uv tool install hcom, on macOS, Linux or Windows. The licence is MIT, and the last commit was on 21 October 2026. It suits people who run several agents at once and want them to hand work to each other instead of copy-pasting. The limit is that delivery quality depends on each tool: those without hooks deliver messages only manually. We have not run it ourselves for this note.
