Frequently Asked Questions

What is a coding agent?▾

A coding agent is an AI tool that helps write, debug, review, and refactor code. They range from autocomplete tools to fully autonomous agents that can implement entire features, run tests, and submit pull requests.

Will coding agents replace developers?▾

No, but they significantly increase developer productivity. Coding agents handle routine implementation and debugging, freeing developers to focus on architecture, design decisions, and complex problem-solving.

How do I choose between GitHub Copilot, Cursor, and Claude Code?▾

GitHub Copilot is best for inline autocomplete and broad IDE support. Cursor provides the deepest codebase-aware chat experience. Claude Code excels at autonomous multi-file tasks from the terminal. Many developers use multiple tools.
