Agentic AI is the next buzzword, but the useful concept is simple: models that plan, call tools, check results, and repeat toward a goal.

Cline is a free, open-source VS Code extension that turns the editor into an autonomous AI coding agent. How it works, pricing, and when to use it.

Claude Skills are folder-based modules that extend Claude with scripts, instructions, and resources. Here's how they work and differ from MCP.

The OpenAI Agents SDK ships agents, handoffs, guardrails, and tracing. Learn how it works, when to use it, and how it compares to LangChain and Pydantic AI.

Pydantic AI explained: the type-safe Python framework for production LLM apps. Features, code examples, and how it compares to LangChain.

Function calling and tool use are the same concept under different names. Learn how LLMs invoke external tools, with examples from OpenAI, Anthropic, and Google.

MCP (Model Context Protocol) is Anthropic's open standard for connecting AI models to tools and data. Architecture, examples, and why it matters.
