The Core Objective of Code Review

According to Mark Dominus via Mathstodon, there is a common misconception regarding the intent of the code_review process. He posits that the fundamental goal is not merely bug hunting, but rather identifying logic that will be difficult to maintain over time.

The primary goal is just to find crashes.

The Maintenance Logic

The cost of software is often represented by the accumulation of technical debt: $\text{Total Cost} = \text{Initial Dev} + \sum (\text{Maintenance Effort})$

"I think many people misunderstand the purpose of [code review]..." — Mark Dominus

Workflow Visualization

Example: Maintainability Gap

Consider this snippet:

# Hard to maintain: Magic numbers and vague naming
def calc(a):
    return a * 1.0825 

The above is hard to maintain because the intent of 1.0825 is hidden.

Review Checklist

• Is the logic intuitive?
• Are naming conventions clear?
• Will a stranger understand this in six months?
