Quick Start

1. Clone and Setup

  }
}

dotnet run

The bot will connect to Discord and register its slash commands globally.

cp .env.example .env

2. Edit .env and set your Discord token:

DISCORD_BOT_TOKEN=YOUR_ACTUAL_TOKEN_HERE

Example Commands

The bot includes example slash commands:

• /general ping - Shows bot latency
• /general hello [user] - Greet a user
• /general botinfo - Display bot information

Adding New Commands

Create a new class in the Commands folder that inherits from InteractionModuleBase<SocketInteractionContext>:

using Discord.Interactions;

namespace TentacleBot.Commands;

public class MyCommands : InteractionModuleBase<SocketInteractionContext>
{
    [SlashCommand("mycommand", "My custom command")]
    public async Task HandleMyCommandAsync()
    {
        await RespondAsync("Hello from my command!");
    }
}

Commands are automatically discovered and registered when the bot starts.

Configuration

appsettings.json

{
  "Discord": {
    "BotToken": "YOUR_BOT_TOKEN_HERE"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning"
    }
  }
}

Troubleshooting

• "Bot token not found": Set DISCORD_BOT_TOKEN in .env (Docker) or in your shell. The app falls back to appsettings.json if the env var is not set
• "Insufficient permissions": Ensure your bot has the necessary permissions in Discord Developer Portal
• Commands not appearing: The bot needs to connect first. Wait a few seconds after starting, then try / in Discord
