To beginner vibe coders,
I will be dropping bite-size info here that will save you time as you try to master agentic development.
Asking AI to build product X with Y features for Z people is like taking shots in soccer blind-folded. Probability of goals scored will be abysmal.
Issue #1
Using comments in .json files.
.json files do not have commenting as a feature unlike many other programming languages.
Whatever code AI writes will be discounted by default if it decides to comment inside .json code.
You might think powerful models won't do it. But they will. Even latest models from 2026 like Gemini 3 Pro will mess up.
Adding this as a context might also not be useful if you have a ton of other important things in the context. That's why it's important to spot this as you review the code the agents output.
I haven't found anything yet that prevents this perenially.
