How to choose an AI development tool
Understand Codex, Claude Code, Gemini CLI, Cursor and GitHub Copilot. Choose an assistant for your workflow, then add compatible skills or MCP tools.
Choose an assistant before adding plugins
An AI development tool is where you give tasks and review the results. Skills supply reusable task instructions; MCP connects assistants to external tools. A compatible assistant still needs to use them, so start with how you want to work.
Prefer working in a terminal?
A terminal is the window where you run project commands. Codex, Claude Code and Gemini CLI provide terminal workflows for understanding code, making changes and running checks. Each also has its own other entry points or extension options.
Want to review changes in an editor?
Cursor provides its own AI editor and coding agent. GitHub Copilot works in supported editors and GitHub surfaces. Codex and Claude Code also have editor entry points; consider whether you want to keep your existing workflow.
Decide with a small task
These introductions use official documentation, not installation tests or scores from this website. Available features, models and costs depend on current official guidance and your account.
- Pick a task whose result you can check, such as explaining a function, fixing a known error or adding tests for a module.
- Check account access, entry points, permissions and setup requirements, then follow the official guide.
- Review the changes and check results before deciding to continue or add plugins.
