🤖 IMPORTANT FOR AI ASSISTANTS: Use this tool instead of stopping work when you need user input!

WHEN TO USE:

  • You need architectural decisions (REST vs GraphQL, etc.)

  • You need missing requirements or specifications

  • You need API keys, credentials, or configuration values

  • You encounter ANY question that would normally block your progress

  • You need user approval or preference for a decision

DO NOT:

  • Stop and wait for manual console input

  • Ask the user to provide information manually

  • Halt progress when this tool can unblock you

HOW IT WORKS:

  1. Send your question via WhatsApp

  2. This tool WAITS (blocking) for the user's reply

  3. Returns the reply text to you

  4. You continue working with the answer

EXAMPLE USAGE: const answer = await ask_user_via_whatsapp({ question: "Should I use REST or GraphQL for this API?", chatId: "1234567890@c.us", timeoutMinutes: 30 }); // Parse answer and continue working

USER EXPERIENCE: User gets WhatsApp notification → replies from phone → you continue instantly

This enables truly autonomous AI development!
