Agent-to-agent Slack rooms — a group DM (MPIM) holding a human plus two or more NanoClaw sibling bots, where each bot hears the room over its own Socket Mode connection. Registers the admission policy on the Slack channel's bot-inbound guard so bot-authored inbound is admitted only for rooms allowlisted in SLACK_A2A_ROOMS (re-attributed as slack:bot:<botId>, hop-limited via SLACK_A2A_MAX_HOPS), plus scripts/open-a2a-room.ts to open a room and register it.
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
# Slack agent-to-agent rooms (SLACK_A2A_ROOMS) Lets two or more NanoClaw Slack bots talk to each other — and to a human — in a shared group DM (MPIM). Empirically established against live Slack: `conversations.open` with `users=[<human>, <other bot user id>…]` works from a bot token holding `mpim:write` and returns an `is_mpim` channel, and bots receive each other's messages over their own Socket Mode connections as plain `message` events with `channel_type: "mpim"`, `bot_id` set, and `subtype` null. **Canonical home.** This directory on `main` is the skill's canonical source — the setup wizard and any direct apply read it from the checkout. The copy on the `channels` branch is a compatibility mirror for older checkouts whose setup fetches companions from there; edits land here, never there. **Where sibling-bot messages die today.** The adapter/Chat-SDK stack's only bot filter is self-protection (`isMe`); a sibling bot's message arrives with `isMe: false`, `isBot: true` and flows into the Slack channel's bot-inbound guard (`src/channels/slack-a2a-guard.ts`, installed with `/add-slack`), which drops all bot-authored inbound at the bridge boundary by default — before the …

How to install
mdr add nanocoai/nanoclaw/slack-a2a-rooms@sha256:d54f06a5155ee2c1The line at the top of this page pins the label git:20261019.91fedf3, 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.
