Discord Bot Architect

# Discord Bot Architect

Specialized skill for building production-ready Discord bots.
Covers Discord.js (JavaScript) and Pycord (Python), gateway intents,
slash commands, interactive components, rate limiting, and sharding.

## Principles

- Slash commands over message parsing (Message Content Intent deprecated)
- Acknowledge interactions within 3 seconds, always
- Request only required intents (minimize privileged intents)
- Handle rate limits gracefully with exponential backoff
- Plan for sharding from the start (required at 2500+ guilds)
- Use components (buttons, selects, modals) for rich UX
- Test with guild commands first, deploy global when ready

## Patterns

### Discord.js v14 Foundation

Modern Discord bot setup with Discord.js v14 and slash commands

**When to use**: Building Discord bots with JavaScript/TypeScript,Need full gateway connection with events,Building bots with complex interactions

```javascript
// src/index.js
const { Client, Collection, GatewayIntentBits, Events } = require('discord.js');
const fs = require('node:fs');
const path = require('node:path');
require('dotenv').config();

// Create client with minimal required intents
const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    // Add only what you need:
    // GatewayIntentBits.GuildMessages,
    // GatewayIntentBits.MessageContent,  // PRIVILEGED - avoid if possible
  ]
});

// Load commands
client.commands = new Collection();
const commandsPath = path.join(__dirname, 'commands');
const commandFiles = fs.readdirSync(commandsPath).filter(f => f.endsWith('.js'));

for (const file of commandFiles) {
  const filePath = path.join(commandsPath, file);
  const command = require(filePath);
  if ('data' in command && 'execute' in command) {
    client.commands.set(command.data.name, command);
  }
}

// Load events
const eventsPath = path.join(__dirname, 'events');
const eventFiles = fs.readdirSync(eventsPath).filter(f => f.endsWith('.js'));

for (const file of eventFiles) {
  const filePath = path.join(eventsPath, file);
  const event = require(filePath);
  if (event.once) {
    client.once(event.name, (...args) => event.execute(...args));
  } else {
    client.on(event.name, (...args) => event.execute(...args));
  }
}

client.login(process.env.DISCORD_TOKEN);
```

```javascript
// src/commands/ping.js
const { SlashCommandBuilder } = require('discord.js');

module.exports = {
  data: new SlashCommandBuilder()
    .setName('ping')
    .setDescription('Replies with Pong!'),

  async execute(interaction) {
    const sent = await interaction.reply({
      content: 'Pinging...',
      fetchReply: true
    });

    const latency = sent.createdTimestamp - interaction.createdTimestamp;
    await interaction.editReply(`Pong! Latency: ${latency}ms`);
  }
};
```

```javascript
// src/events/interactionCreate.js
const { Events } = require('discord.js');

module.exports = {
  name: Events.InteractionCreate,
  async execute(interaction) {
    if (!interaction.isChatInputCommand()) return;

    const command = interaction.client.commands.get(interaction.commandName);
    if (!command) {
      console.error(`No command matching ${interaction.commandName}`);
      return;
    }

    try {
      await command.execute(interaction);
    } catch (error) {
      console.error(error);
      const reply = {
        content: 'There was an error executing this command!',
        ephemeral: true
      };

      if (interaction.replied || interaction.deferred) {
        await interaction.followUp(reply);
      } else {
        await interaction.reply(reply);
      }
    }
  }
};
```

```javascript
// src/deploy-commands.js
const {
