| description | Slack CLI for agents: read URLs/threads/history/unreads/later/canvases/workflows, search messages/files, download attachments, lookup users, list/create/invite channels, open DMs, draft messages, schedule sends, and explicit sends/edits/deletes/reactions/mark-read/uploads. |
CLI on $PATH: agent-slack .... If missing, prefer:
curl -fsSL https://raw.githubusercontent.com/stablyai/agent-slack/main/install.sh | sh
Fallback: npm i -g agent-slack (Node >= 22.5).
Safety: read/search freely. Do not send, edit, delete, react, invite, create channels, mark read, schedule, upload, or cancel scheduled messages unless explicitly asked. Prefer message draft.
Auth: agent-slack auth whoami; if needed auth import-desktop, auth import-brave, auth import-chrome, or auth import-firefox, then auth test.
