agentcomm skillA
agentcomm is agent-read markdown (skill) from uchicago-dsi/ai-sci-skills: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

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@git:20260922.0776e0fmdr add uchicago-dsi/ai-sci-skills/agentcomm@sha256:9c090f3f689c8b3aPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
