AI agents should use contextual retrieval instead of growing system prompts

An AI agent's system prompt should not accumulate instructions for every past failure, as this can lead to unnecessary complexity and cost. Instead, a proposed architecture separates the agent's functions into learning and execution loops. The learning loop analyzes task outcomes to identify and store relevant lessons, while the execution loop retrieves these lessons contextually for new tasks, keeping the main prompt focused on stable rules. This approach aims to improve agent performance by providing targeted guidance rather than a monolithic set of instructions. AI

IMPACT Suggests a more efficient architecture for AI agents by separating learning and execution, potentially reducing token costs and improving task relevance.
