Connect a Slack app to the Vellum Assistant via Socket Mode. Use whenever the user wants to set up Slack for their assistant, connect a workspace, or get the assistant talking in Slack — opens a guided setup wizard in the side panel so the user can create the app, generate tokens, and connect in one flow.
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
## Scope
This skill connects an assistant to a Slack workspace: first-time bot identity (tokens, scopes, events), or switching workspaces and rotating tokens. Runtime Slack operations (posting, reading channels, triage) belong to the separate `slack` skill.
## Step 1 — Check existing configuration
Run `assistant credentials list --search slack_channel` (via the bash tool). Scan the result for entries with `service: slack_channel` and note which of `app_token`, `bot_token` are present.
Then branch:
- If **both ✅** → fully configured. Offer to show status or reconfigure. Stop here unless the user wants a reset.
- **Otherwise** → continue to Step 2.
> ✓ Checkpoint: You named which of `app_token` / `bot_token` are present before branching. Do not skip the `assistant credentials list` call and guess.
## Step 2 — Open the setup wizard
Call `ui_show` with `surface_type: "channel_setup"` and `data: { channel: "slack" }`. This opens the Slack setup wizard in the side panel. The wizard is non-blocking — the tool returns immediately.

How to install
mdr add vellum-ai/vellum-assistant/slack-app-setup@sha256:991e4da25f4d93f2The line at the top of this page pins the label git:20260903.5802532, 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.
