How Do AI Agents Work? Tools, Permissions, Mistakes And Human Oversight

An AI Agent Becomes Consequential When Its Answer Can Trigger A Tool That Changes Something. An ordinary chatbot can draft a response. An AI agent can use available tools to search, read, calculate, write files or interact with an application while pursuing a goal. The important mechanism is a loop: receive a task, choose an action, inspect the result and decide what to do next. How much harm or help that loop can produce depends on its tools, permissions and supervision.
