Agent Loop: Observe, Decide, Act

The Agent Loop: How AI Makes Decisions

The core pattern all agents follow:

1. Observe: Gather information about the current situation
2. Decide: Determine what action to take next
3. Act: Execute the action using available tools
4. Repeat: Loop until goal is achieved

Example: "Help me study for Friday's test"

• Observe: Today is Tuesday, test is in 3 days, topic is calculus
• Decide: Check student's calendar for free time
• Act: Call calendar API → sees Wednesday 4-6pm free
• Observe: Found 2-hour block, need study materials
• Decide: Search for calculus practice problems
• Act: Call web_search → found Khan Academy resources
• Observe: Have time slot and materials
• Decide: Create study plan and set reminder
• Act: Call create_event, set_reminder → Done!
