                  Configure Slack channel tokens (bot token + app-level token).
                  
                      [ReadWriteBash(cmd:chmod)"]
                    
                
                
                  /slack-channel:configure
Configure the Slack channel with your bot token and app-level token.
Usage

/slack-channel:configure <xoxb-bot-token> <xapp-app-token>

Instructions

Parse the two arguments from $ARGUMENTS:


First token must start with xoxb- (Bot User OAuth Token)
Second token must start with xapp- (App-Level Token)


If either token is missing or has the wrong prefix, show this error and stop:


   Error: Two tokens required.
     - Bot token (starts with xoxb-) from OAuth & Permissions
     - App token (starts with xapp-) from Socket Mode settings

   Usage: /slack-channel:configure xoxb-... xapp-...


Create the state directory if it doesn't exist:


   ~/.claude/channels/slack/


Write the .env file at ~/.claude/channels/slack/.env:


   SLACK_BOT_TOKEN=<bot-token>
   SLACK_APP_TOKEN=<app-token>


Set file permissions to owner-only:


   chmod 600 ~/.claude/channels/slack/.env


Confirm success:


   Slack channel configured.

   Start Claude with the Slack channel:
     claude --channels plugin:slack-channel@claude-code-plugins

   Or for development:
     claude --dangerously-load-development-channels server:slack

Security

Never echo the tokens back in the confirmation message
Never log tokens to stdout or any file other than .env
Always set 0o600 permissions on the .env file
