Control costs and prevent runaway tool calls in reasoning agents

Agno now allows a **tool_call_limit** to be set for the default reasoning agent. Teams can prevent infinite or excessive tool calls, reducing compute costs and ensuring predictable workflow execution.

This capability improves governance, operational control, and reliability in production agent deployments.

**Why this matters**

- Limits runaway or costly tool executions
- Provides stronger operational control over agent behavior
- Supports predictable performance and cost management
