SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires anthropic, ClaudeAPI, AgentSDK, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill provides the necessary tools and guidance to build LLM-powered applications using the Claude API or Anthropic SDK, enabling the development of intelligent applications with language understanding capabilities.

Core Features & Use Cases

  • Build LLM Apps: Offers a comprehensive guide for building applications with Claude, including selecting the right model, language detection, and choosing the appropriate surface (API, agent, or workflow).
  • Language Detection: Automatically detects the language of the project for targeted documentation and examples.
  • Surface Selection: Assists in choosing the right surface for the application, such as the Claude API for single calls, workflows for multi-step processes, or agents for flexible, open-ended tasks.
  • Documentation: Provides extensive documentation for various programming languages, including Python, TypeScript, Java, Go, Ruby, C#, and PHP, with examples and code snippets.
  • Tool Use: Explains how to use tools with Claude, including function calling, code execution, memory, and structured outputs.

Quick Start

Use the claude-api skill to build an application that classifies text with the Claude API. For example: 'classify the text "The weather today is sunny." as "positive" or "negative."'

FAQPage Schema
How do I build an LLM-powered application using the Anthropic SDK?

Build an LLM-powered application using the Anthropic SDK by selecting the right Claude model, detecting the project language, and choosing the appropriate surface like the API for single calls or agents for open-ended tasks.

What is the best way to use the Claude API for multi-step processes?

The best way to use the Claude API for multi-step processes is to select the workflow surface, which orchestrates complex sequences, while the API surface handles single calls and agents manage flexible, open-ended tasks.

Does the Claude API support tool use and function calling in TypeScript?

Yes, the Claude API supports tool use in TypeScript and other languages by enabling function calling, code execution, memory handling, and structured outputs to extend natural language understanding capabilities.

Can I use the Claude API with programming languages other than Python?

Yes, you can use the Claude API with Python, TypeScript, Java, Go, Ruby, C#, and PHP, receiving targeted documentation, code snippets, and examples specific to your detected project language.

When should I use agents instead of the Claude API for natural language generation?

Use agents instead of the Claude API when your application requires flexible, open-ended tasks, reserving the API for single calls and workflows for structured, multi-step natural language generation processes.

How do I classify text as positive or negative using the Claude API?

Classify text using the Claude API by making a single call with a prompt like 'classify the text as positive or negative,' leveraging the API surface for straightforward natural language understanding tasks.
