Slack Expert Skill

Overview

Full-platform Slack development using the Bolt SDK. Covers interactive app development beyond basic messaging — slash commands, modals, shortcuts, home tabs, event subscriptions, workflow steps, and multi-workspace OAuth.

Related skill: slack-notifications — use that skill for simple one-way messaging/alerts. Use slack-expert when building interactive Slack apps or bots.

Requirements

Variable	Purpose	Required
SLACK_BOT_TOKEN	Bot OAuth token (xoxb-...)	Yes (single workspace)
SLACK_SIGNING_SECRET	Request signature verification	Yes
SLACK_APP_TOKEN	Socket Mode app-level token (xapp-...)	Socket Mode only
SLACK_CLIENT_ID	OAuth client ID	Multi-workspace only

Quick Start — Bolt App (Node.js)

const { App } = require('@slack/bolt');

const app = new App({
  token: process.env.SLACK_BOT_TOKEN,
  signingSecret: process.env.SLACK_SIGNING_SECRET,
  // For Socket Mode, add:
  socketMode: true,
  appToken: process.env.SLACK_APP_TOKEN,
});

// Slash command
app.(,  ({ command, ack, respond }) => {
   ();
   ();
});


app.(,  ({ body, ack, client }) => {
   ();
   client..({
    : body.,
    : confirmationModal,
  });
});


app.(,  ({ event, say }) => {
   ({ : , : event. });
});

( () => {
   app.(process.. || );
  .();
})();
