Optimize Your Google ADK Agent's SOP with GEPA: Stop Manual Tweaking
· 6 min read
Published: November 7, 2025
Your agent's instructions are its Standard Operating Procedure (SOP). In Google ADK, this SOP lives in the agent's prompt—the detailed instructions that guide every decision, every tool call, every response.
The problem? Writing the perfect SOP manually is nearly impossible. You add rules to fix failures. Each new rule breaks something else. Your agent becomes unpredictable. Your SOP becomes a mess of band-aids.
The solution? GEPA (Genetic Evolutionary Prompt Augmentation)—automatic SOP optimization that learns from failures and evolves better instructions through real testing.
