+Example demonstrating the new reasoning interval and adaptive reasoning features in CrewAI.
 
 This example shows how to:
-1. Use reasoning_interval to make an agent reason every X steps
-2. Use adaptive_reasoning to let the agent decide when to reason
+1. Create an agent with a fixed reasoning interval (reason every X steps)
+2. Create an agent with adaptive reasoning (agent decides when to reason)
+3. Configure and run tasks with these reasoning capabilities

+How the reasoning features work:
+
+1. Interval-based reasoning (reasoning_interval=3):
+   - The agent will reason after every 3 steps of task execution
+   - This creates a predictable pattern of reflection during task execution
+   - Useful for complex tasks where periodic reassessment is beneficial
+
+2. Adaptive reasoning (adaptive_reasoning=True):
+   - The agent decides when to reason based on execution context
+   - Reasoning is triggered when:
+     a) Multiple different tools are used recently (indicating a change in approach)
+     b) The task is taking longer than expected (iterations > max_iter/2)
+     c) Recent errors or failures are detected in the execution
+   - This creates a more dynamic reasoning pattern adapted to the task's needs
+
+Both approaches enhance the agent's ability to handle complex tasks by allowing
+mid-execution planning and strategy adjustments.
