Implementation Reference

src/core/AutomationManager.ts:101-104 (handler)

The core handler function that executes the discord_add_reaction tool logic. Validates input parameters using AddReactionSchema and delegates the actual Discord API call to DiscordService.addReaction.

async addReaction(channelId: string, messageId: string, emoji: string): Promise<string> {
  const parsed = schemas.AddReactionSchema.parse({ channelId, messageId, emoji });
  return await this.discordService.addReaction(parsed.channelId, parsed.messageId, parsed.emoji);
}

src/types.ts:44-48 (schema)

Zod schema defining the input parameters and validation for the discord_add_reaction tool: channelId, messageId, and emoji.

export const AddReactionSchema = z.object({
  channelId: z.string().describe("Discord channel ID"),
  messageId: z.string().describe("Discord message ID"),
  emoji: z.string().describe("Emoji (Unicode or string)")
});

src/core/DiscordController.ts:69-80 (registration)

Dynamic registration/dispatch mechanism in DiscordController that maps tool names like 'add_reaction' (or 'discord_add_reaction') to camelCase method names (e.g., 'addReaction') on AutomationManager for execution.

private async callAutomationMethod(action: string, params: any): Promise<string> {
  // Convert action name to method name (snake_case to camelCase)
  const methodName = action.replace(/_([a-z])/g, (g) => g[1].toUpperCase());
  
  // Check if method exists
  if (typeof (this.automationManager as any)[methodName] === 'function') {
    // Call the method with params
    return await (this.automationManager as any)[methodName](...Object.values(params));
  }
  
  throw new Error(`Method '${methodName}' not found in AutomationManager`);
}

src/core/AutomationManager.ts:11-22 (helper)

Helper method in AutomationManager for dynamic execution of actions, supporting snake_case tool names converted to camelCase methods.

async executeAction(action: string, params: any): Promise<string> {
  // Convert action name to method name (snake_case to camelCase)
  const methodName = action.replace(/_([a-z])/g, (g) => g[1].toUpperCase());
  
  // Check if method exists
  if (typeof (this as any)[methodName] === 'function') {
    // Call the method with params
    return await (this as any)[methodName](...Object.values(params));
  }
  
  throw new Error(`Method '${methodName}' not found in AutomationManager`);
}
