Claude Tool Use & Function Calling
Enables Claude to execute external actions like querying databases and calling APIs through standardized function calling patterns.
This skill provides a comprehensive framework for implementing tool use (function calling) within Claude Code, allowing the model to interact directly with external systems, databases, and third-party APIs. It covers the complete lifecycle of tool integration, from defining JSON schemas and handling tool use requests to executing code and managing autonomous agentic loops. By standardizing how Claude requests and processes external data, this skill empowers developers to build sophisticated AI-powered agents capable of real-world task execution and complex multi-step workflows.
