agent-slack
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.
Common commands:
agent-slack message get "SLACK_URL"
agent-slack message list "SLACK_URL"
agent-slack message list "general" --limit 20
agent-slack search messages "query" --channel "general"
agent-slack message draft "general" "text"
agent-slack message send "URL_OR_CHANNEL" "text" --attach ./file.md
agent-slack message send "general" "text" --schedule-in "3h"
agent-slack message scheduled list
agent-slack message scheduled cancel "SCHEDULED_ID" --channel "CHANNEL_ID"
agent-slack unreads
agent-slack later list
agent-slack canvas get "CANVAS_URL"
agent-slack workflow list "general"
agent-slack user list
agent-slack channel list
agent-slack user dm-open @alice @bob
With multiple workspaces, pass --workspace "team" or set SLACK_WORKSPACE_URL. Attachments include local path in JSON.
For non-trivial usage, read the bundled references:
- references/commands.md: command map and flags
- references/targets.md: URL vs channel targeting rules
- references/output.md: JSON shapes and download paths

Use when work should span one or more detached tasks but still behave like one job with a single owner context. TaskFlow is the durable flow substrate under authoring layers like Lobster, ACPX, plugins, or plain code. Keep conditional logic in the caller; use TaskFlow for flow identity, child-task linkage, waiting state, revision-checked mutations, and user-facing emergence.
