Earlier quoted context omitted.
Cursor and Windsurf are both forks of VS Code, an editor.
Yes very observant, modified forks with their agents built in. Zed does not have any built in, sublime does not have agents built in but if you like you can continue this disingenuous discussion.
It's not only that they have it built in but it seems to be currently the best open replacement for tools like claude code cli because you can use arbitrary llm with it, ie. from ollama and you have great extension points (mcp servers, rules, slash commands etc).
