Create Slack App

Help the developer create a Slack app or agent using Bolt for $0.

This skill walks through the full setup: prerequisites, authentication, sandbox creation, project scaffolding from a template, and running the app locally.

Step 1: Check Prerequisites

1a. Detect the Slack CLI command

Use the slack:slack-cli skill — Step 1: Detect the Slack CLI — to check whether the public Slack CLI is installed and resolve its command name. The fingerprint check, alias fallback, and install instructions all live there; do not duplicate them here.

Once resolved, use the detected command name for all CLI commands throughout the rest of this skill. We refer to it as SLACK_CMD below — substitute the actual resolved command name everywhere you see SLACK_CMD.

1b. Verify the CLI version

Run SLACK_CMD version and print the version to confirm everything is working before continuing.
