YAGNI
YAGNI (You Aren't Gonna Need It) is a software engineering principle from Extreme Programming (XP), attributed to Kent Beck and others. Its core tenet is that developers should implement only the functionality that is currently and explicitly required, rather than building features in anticipation of future needs. The principle aims to reduce unnecessary code complexity and lower maintenance costs. It is commonly applied alongside DRY and KISS principles and forms an important part of agile development methodology.

The code implementation pattern the author recommends is: the minimal implementation serving the immediate need, plus a comment explaining the boundaries of the current implementation and the starting point for generalization when requirements expand, rather than writing the abstraction layer in advance.
YAGNI requires that the timing of abstraction be driven by real needs, and a common way to judge is to extract an abstraction when the second or third real use case appears and a common pattern can be generalized.
YAGNI (You Aren't Gonna Need It) is one of the core principles of Extreme Programming (XP), advocated by Ron Jeffries and others, holding that code or extension points should not be written for a requirement before it actually appears.
YAGNI is a core principle of extreme programming, advocating that only functionality that is currently actually needed should be implemented, avoiding over-engineering for hypothetical future scenarios.
The YAGNI principle (You Aren't Gonna Need It) was proposed by Kent Beck, the founder of the Extreme Programming (XP) methodology.
A pragmatic technology evolution strategy is to use lightweight solutions for rapid validation in early project stages and migrate to a vector database after scale increases, which is consistent with the YAGNI principle.
The YAGNI principle (You Aren't Gonna Need It) is one of the core practices of Extreme Programming (XP), reminding developers not to write code in advance for requirements that have not yet emerged.
