Google ADK tool errors that fix themselves

This content discusses how to prevent a single failed tool call from terminating a Google ADK agent's turn by implementing the Reflect and Retry plugin. The plugin enables agents to recover from tool errors autonomously, allowing them to reflect on failures and attempt alternative approaches without losing their turn. This improves agent resilience and reduces the need for manual intervention when tools fail.

Key Points

• •Single tool failures can prematurely end an agent's turn in Google ADK without error handling
• •The Reflect and Retry plugin allows agents to continue operating after tool call failures
• •Agents can autonomously reflect on what went wrong and retry with different parameters or approaches
• •Implement error recovery to reduce manual intervention and improve agent robustness
• •Tool errors become learning opportunities rather than hard stops in the agent workflow
• •The plugin integrates with Google ADK's tool calling mechanism to catch and handle failures gracefully
• •Agents maintain context and turn continuity when recovering from tool errors
• •This pattern is essential for production-grade agents that need high reliability
