This skill should be used when the user asks to "monitor a Slack channel", "watch Slack for messages", "create a Slack bot that responds to mentions", "set up an OpenHands Slack integration", "trigger OpenHands from Slack", "respond to @openhands in Slack", or "poll Slack channels for a trigger phrase". Guides the user through creating a cron automation that watches up to 10 Slack channels and starts an OpenHands conversation whenever a configurable trigger phrase is detected.
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 Channel Monitor Create a cron automation that polls up to 10 Slack channels every minute. Windows PowerShell equivalents for the setup, packaging, upload, and API-check shell snippets are in `references/windows.md`. When a message containing the **trigger phrase** (default: `@openhands`) is detected it: 1. Adds a 👀 reaction to the triggering message. 2. Opens an OpenHands conversation with the message and recent channel context. 3. Posts a reply in the Slack thread with a link to the conversation. On every subsequent run: - New Slack thread replies are forwarded only when they contain the trigger phrase, so unrelated conversation in the thread is ignored. - When the conversation finishes (or errors), the agent's final response is posted back to the Slack thread. - Completed conversations stay in a short follow-up watch window, allowing triggered Slack replies to continue the same OpenHands conversation. > Runs on a local Agent Canvas (`dev:automation` stack) and on OpenHands Cloud > and Enterprise. On Cloud and Enterprise each conversation is started through > the OpenHands API in a sandbox of its own, with the user's own settings, and …

How to install
mdr add openhands/extensions/slack-channel-monitor@sha256:89d06536816c55daThe line at the top of this page pins the label git:20261029.100fb5a, 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.
