Writing Effective Tools for AI Agents

The text provides an extensive guide from Anthropic on how to write effective tools for AI agents, particularly focusing on the use of their agent, Claude, to optimize these tools. It begins by explaining that tools act as a contract between deterministic systems and non-deterministic agents, necessitating a new approach to software development. The core process described involves building prototypes, running comprehensive evaluations using realistic tasks, and collaborating with agents like Claude Code to iteratively improve tool performance. Key principles for effective tool design include choosing targeted, high-impact tools over wrappers for existing APIs, namespacing tools to define clear functional boundaries, and returning meaningful context that is also token-efficient for the agent. Finally, the guide emphasizes the importance of prompt-engineering tool descriptions to steer agents toward correct and efficient usage. ============== Code content percentage: 0.336% Total text length: 21456 characters 🔗 Original article: https://www.anthropic.com/engineering/writing-tools-for-agents 📋 Monday item: https://omril321.monday.com/boards/3549832241/pulses/10060351760
