AI Agents Carry a Tool Belt

AI agents have a 'tool belt' — search, calculator, calendar, and more. They pick the right one for each step.

Some examples

• For a math step, the agent uses the calculator tool.
• For news, the agent uses the search tool.
• For setting a meeting, the agent uses the calendar tool.
• More tools = more things the agent can do.

What's actually in an AI agent's tool belt

A plumber shows up with a full tool belt — wrenches, tape, pipe cutters — and chooses whichever tool is right for each job. AI agents work exactly the same way. Instead of wrenches, an AI agent's belt might hold a web search tool, a calculator, a code runner, a calendar reader, an email sender, and a file manager. Each tool has one job. The web search tool finds information online. The calculator does precise math without rounding errors. The code runner actually executes programs and returns the output. The magic is that the agent decides which tool to pick at each step — you don't have to tell it. When you ask 'what's 15% of $47.50 for a tip?', a smart agent reaches for the calculator tool, not the search tool. This tool-picking ability is what makes agents feel intelligent rather than just quick at typing.

• Web search: looks up current information from the internet
• Calculator: performs exact arithmetic without AI guessing errors
• Code runner: writes and executes code to solve problems or test ideas
• File reader: opens and reads documents, spreadsheets, and PDFs
• Calendar/email: reads and (if permitted) writes to scheduling and messaging apps
