Argument normalization

Every generated method accepts either positional arguments (mapped by parameterOrder) or a single options object (with key aliases resolved).

await client.sendText('447123456789@c.us', 'Hello, world!');
// positional args map by parameterOrder -> { to, content, options }

await client.sendText({ chatId: '447123456789@c.us', text: 'Hello, world!' });
// key aliases normalize -> { to, content }

Steps: 1) resolve positional/object args, 2) normalize key aliases, 3) inputSchema.parseAsync() validates, 4) dispatch to execute(...). Invalid input rejects before any WhatsApp call.
