Summary

This post explains Anthropic's Advisor tool pattern for cutting cost. A smarter, more expensive advisor model guides the work, and cheaper executor models do most of it. The post links to the official Claude Platform documentation.

Key points

• Advisor model: the smartest and most expensive model, used for guidance.
• Executor models: cheaper models that do most of the work.
• The goal is to send most tokens to cheaper models while keeping strong-model judgment.
• The Advisor tool is documented under Agents and Tools > Tool use on the Claude Platform.
