The agent loop

Agents work in a cycle called the agent loop:

  1. Think — given the goal and what's happened so far, decide the next step
  2. Act — call a tool (run a command, edit a file, fetch a page)
  3. Observe — read the tool's result
  4. Repeat until the goal is reached (or the agent asks you for help)
