The skill requires users to provide an API key directly in chat, creating a credential harvesting risk if the skill or its underlying scripts are compromised. It executes arbitrary shell commands via exec() to interact with an external SMS service, which could be redirected to malicious endpoints. While the stated purpose (SMS verification) is legitimate, the implementation pattern bypasses standard secure credential handling.

A user wants to create an Instagram account anonymously. The skill requests a virtual number for Instagram from Grizzly, navigates to Instagram’s signup page, enters the number, waits for the SMS code, and finishes the registration process.
A user’s balance is low and they need to top up. The skill checks the current balance, retrieves a USDT (TRC-20) wallet address, and displays instructions for sending at least 50 USD to automatically credit the account.
A user needs to verify accounts on multiple platforms (e.g., Telegram, WhatsApp, Facebook) using virtual numbers. The skill sequentially requests numbers for each service, performs the browser registration, captures SMS codes, and activates the numbers.
A user needs a temporary phone number to receive a one-time SMS code for testing or anonymous verification. The skill rents a virtual number from Grizzly, displays the number and activation ID, and retrieves the SMS code when sent.
Offer a subscription service where users pay a monthly fee to access a pool of virtual phone numbers for SMS verification across various platforms.
Provide a pay-as-you-go API for developers to integrate virtual number and SMS verification into their applications, charging per SMS received or per number rented.

💬 Integration Tip
Ensure the exec command environment variable GRIZZLY_SMS_API_KEY is always passed from user input; use the browser tool with headless=false so the user can observe registration steps on their screen.
