Slack CLI

Use the Slack CLI to create, run, and manage Slack apps — including calling Web API methods directly and searching Slack developer documentation from the terminal.

For initial setup (sandbox creation, project scaffolding from templates), use the slack:create-slack-app skill instead.

Step 1: Detect the Slack CLI

Resolve the path to the public Slack CLI before running any other command. We refer to the resolved value as SLACK_CMD — substitute it everywhere below. Try 1a → 1b → 1c in order; do not skip ahead.

1a. Standard install path (preferred — no verification needed)

The official install scripts place the binary at a fixed per-user path. If the file exists, use it directly: only the install script writes to that path.

• macOS / Linux: ~/.slack/bin/slack
• Windows: %USERPROFILE%\AppData\Local\slack-cli\bin\slack.exe (or %USERPROFILE%\.slack-cli\bin\slack.exe as a fallback)
