In the chat completions API format used by OpenAI, Anthropic, Google, and others, messages come in three roles: system, user, and assistant. The system message is the system prompt, it's processed first, with higher conceptual priority than user turns, and persists across the entire conversation.
What Goes in a System Prompt
Prompt engineering is the discipline of communicating effectively with large language models. Because LLMs are trained to predict plausible continuations of text, how you frame a request has an enormous impact on what you get back, the same underlying model can behave like an expert assistant or produce generic noise depending on prompt quality.

OpenHands (formerly OpenDevin) is an open-source platform for AI software engineering agents. Unlike Cursor or Windsurf which are IDEs with AI assistance, OpenHands is a platform where AI agents operate autonomously, writing code, executing shell commands, browsing the web, and iterating until a task is complete.
How OpenHands Works
OpenHands runs agents inside isolated Docker containers. The…
GitHub Copilot, launched in 2021 and built on OpenAI Codex (later GPT-4), was the first AI pair programmer to reach mainstream adoption. It integrates as an extension into VS Code, JetBrains, Neovim, and Visual Studio, making it the broadest-reaching AI coding tool by editor support.
Core Capabilities
Cursor is a fork of VS Code that reimagines the editor as an AI-native environment. While GitHub Copilot adds AI as a plugin to existing editors, Cursor was built from the ground up with AI as a first-class participant, not an afterthought.
Core Features
Model Context Protocol (MCP) is an open standard introduced by Anthropic in late 2024 that defines a universal way for large language models to communicate with external systems, files, databases, APIs, and developer tools, without requiring custom integrations for every combination.
The Problem MCP Solves
Before MCP, every AI application had to build its own integrations: Cursor connected to…
Who doesn’t want an AI to pump out more code in minutes than a human might write in a month? Who doesn’t like magic? That’s what the hype around vibe coding has asked of developers and business users alike since its inception.
But now the tools might have matured enough to deliver.
Yes, cautious leaders are right in wondering, “What’s the catch? Is this a trap?” After all, the AIs learned to…
Windsurf is pushing deeper into the AI coding race with Windsurf 2.0, a new Agent Command Center, and native Devin integration.
Cybersecurity researchers from Bitdefender, a provider of an endpoint detection and response (EDR) platform, have discovered an extension to the Windsurf integrated development environment (IDE) that steals credentials and data after code is downloaded from the Solana blockchain platform. Silviu Stahie, a security analyst for Bitdefender, said the extension makes use of typosquatting tactics to…
