Create Slack App

Help the developer create a Slack app or agent using Bolt. If $0 is exactly bolt-js or bolt-python, treat it as the chosen framework and skip asking. Otherwise (including if it's empty or any other value), ignore it and ask the developer which framework they want before continuing.

This skill walks through the full setup: prerequisites, authentication, choosing a workspace to install into, 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.
