description: 'Vibe coding won't work in the long run'

Some of you might miss discussion of the _Agent_ or _agentive_ mode of VS Code and Copilot, which works similarly to other editors like Cursor or Windsurf. This functionality has been added to VS Code very recently, and I haven't been able to try it yet. For that, I've used the Cline extension, which I'll explain next.

[Cline](https://cline.bot/) is an extension for VS Studio that incorporates the _agentive_ mode into the editor. In this case, you pass a prompt with information about what you want to implement, and **the agent does it by itself**. When you see it working, creating files, adding code, installing dependencies, and executing commands in the console, you can't help but think that these agents have something magical about them.

This is interesting. The AI (especially in _agentive_ mode) thinks like we developers do. It writes a function, adds parameters, and tries to fulfill what you asked for. If you told it to add tests, it will do that too, and it will run them after to see if the code does what it's supposed to do. **My surprise is that the AI doesn't generate the code correctly on the first try**, and it needs several iterations to make it work. Sometimes, too many iterations. Since the AI can generate code much faster than a human, it starts developing and executing things one after another. It tries different approaches until it makes it work. **If you're not careful, it can create quite a mess and use up your tokens**. This gets worse if you have auto-accept enabled in Cline, and you let the agent run freely instead of having it ask you occasionally.
