Coordinate agents through the AgentComm mailbox - installing it, binding a durable name, how Codex and Claude hooks notify, and what may not be sent through it. Use when agents of any kind coordinate with each other, when delegating to a worker agent, or when a message appears not to have been delivered.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AgentComm ## Default To The Mailbox Default to AgentComm for peer and Claude-worker assignments, replies, and coordination. Do not duplicate the conversation through tmux. Use tmux only for a verified wake-up need, onboarding, or a failed or unavailable mailbox; state the reason and keep a wake-up notice short, pointing to the mailbox. An unread message alone is not proof of a failed communication channel. ## Where It Lives Install `agentcomm` user-wide rather than inside a project environment, so the mailbox survives environment switches and every agent on the machine reaches the same one. A reference layout: the binary on `PATH` under `~/.local/bin`, the pinned npm package `@yonidavidson/agentcomm@0.21.0` under `~/.local/lib/agentcomm`, and messages under `~/.local/share/agentcomm/mailbox`. Keep the mailbox outside Git and outside cache directories. Pin the package version: the roster and read-state semantics below are what that version does. ## Bind A Durable Name Once Per Session Codex agents run `agentcomm bind <name>` once per session, using their own durable name. **Claude must run `agentcomm register --as <name>` as well.** Setting …

How to install
mdr add uchicago-dsi/ai-sci-skills/agentcomm@sha256:997196df627f103cThe line at the top of this page pins the label git:20261018.a12f4c4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
