Over-engineering and excessive abstraction layers in codebases

Somewhat conflicting opinions expressed across different layers of abstraction that you build into your app over time. In not having an opinion you try to satisfy many ways of solving problems introducing more edge case problems and serious over engineering.

Many developers do not thoroughly study their applications and attempt to fit information into the applications they read. Adding everything can make the project unnecessarily complicated and slow down the development process.

We know creating abstraction layer on abstraction layer is a recipe for failure. While the idea of utility classes is great, Tailwind took it to the extreme.

You have to go through 5 layers of abstraction just to change a minute detail. Heavy nesting of chains, agents, and prompts hides core logic. Errors wrapped inside internal framework layers result in difficult stack traces and longer debugging time.

Reusable modules are still hard: Teams crave typed, API-like modules—but HCL's flexibility is a double-edged sword for large teams... deep dependency chains and over-abstracted components make debugging painful. Changing one variable in a shared module can trigger unrelated updates in production.

Forcing Abstract Factories into a 100-line script? YAGNI!

If you're working in the codebase where you need to make jumps to ten different definitions in order to understand the inheritance chain or follow the path of the business logic, then you have probably over-engineered the shit out of it.
