Anthropic Workbench is the official browser playground inside the Claude developer console for iterating on prompts. Tune system prompts, switch Claude models, adjust parameters, generate test cases, and export ready-to-paste code.

Tool Choice is a parameter on the Anthropic Claude Messages API that controls how Claude selects tools. This guide covers the auto, any, tool, and none modes, along with disable_parallel_tool_use and patterns for forcing tool calls.

The Code Execution Tool is Anthropic's official Claude API tool that runs Python in a managed sandbox. Architecture, patterns, pricing, and how it differs from Bash Tool.

The Files API is Anthropic's endpoint for persistent file storage in the Claude API. Learn upload limits, file_id reuse patterns, beta header requirements, and how it compares to the OpenAI Files API with working code samples.

Token Counting lets you measure how many tokens a Claude API request will use before sending it. This guide covers Anthropic's Token Counting endpoint, rate limits, cost estimation, and best-practice patterns.

An MCP Server is a process that exposes tools, resources, and prompts to AI models like Claude through the Model Context Protocol. Learn its architecture, JSON-RPC mechanics, Python and TypeScript SDKs, and how it powers Claude Desktop, Cursor, and other AI clients.

Tool Use lets LLMs call external functions and APIs. Learn design patterns, MCP, parallel tool calls, and production best practices.

A complete guide to Claude Agent SDK: definition, how it works, advantages, disadvantages, comparisons, and real-world use cases.

REST (Representational State Transfer) is an architectural design principle for building distributed hypermedia systems. REST defines a set of constraints for creating web services that are simple, scalable, and maintainable. By leveraging HTTP protocol semantics and designing APIs around resources and standard HTTP methods, REST enables the construction of intuitive and interoperable web services that...

What is an SDK? A Software Development Kit (SDK) is a comprehensive package of tools, libraries, documentation, code samples, and other resources designed to help developers build applications for a specific platform or service. It provides an integrated development environment that enables developers to efficiently create applications while maximizing the capabilities of the target platform....
