By PulseAugur Editorial · [1 sources] ·

GitHub has found that improving the instructions for its Copilot code review agent, rather than changing the tools it uses, significantly reduces costs. By rewriting the agent's tool instructions to better guide its decision-making process, GitHub was able to cut average review costs by approximately 20% while maintaining review quality. This approach emphasizes precise questioning and controlled tool usage, preventing the agent from entering costly, open-ended exploration loops. AI
