Chat with Grok via Twitter
AI agents call grok_chat to retrieve information from Agent Twitter Client without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool sends a message to Grok (Twitter's AI) and retrieves a response. It is primarily a read/query operation — submitting a prompt and getting back text. There are no direct side effects like posting tweets, modifying data, or financial actions. The main risk is information leakage or prompt injection, but the blast radius is low.
