Requires slackcli (shaharia-lab) — install via run_onchange_45 script. Authenticate with `slackcli auth login` before first use.
agentic-workstation Slack Assistant (slackcli)
Use the slackcli CLI (from shaharia-lab/slackcli)
for Slack workspace automation: reading messages, sending messages, reactions, and canvases.
Important: This is NOT the official Slack Developer CLI (slack/slack-dev).
Use the slack-cli skill for Slack app development workflows.
Use --workspace=<name-or-id> to target a specific workspace.
Without --workspace, the default workspace set via slackcli auth set-default is used.
When to Use
User asks "what's in #channel-name" or "check the Slack channel"
User wants to send a message or reply to a thread
User asks about Slack canvases
User wants to add a reaction to a message
Workspace is agentic-workstation.slack.com (or whichever workspace the user indicates)
