Code Review Policy
Challenge:
Can human code reviews be replaced
with ChatGPT?

Using ChatGPT for Code Review

What is a “Prompt”?
– The command text given to ChatGPT
• Refactor the following code
• Refactor the following code without splitting it
• Refactor the following code using a guard clause
• Refactor the following code using array_map()
• Refactor the following test code using Scenario Outline
…and so on
It might also be a good idea to start with the suggestion "You are a
code reviewer."

…and so on
code reviewer."

1. Refactor if-else Statement by Guard Clause

Refactor the following
code using a guard
clause

code using a guard
clause

code using a guard
clause
Refactor the following code

code using a guard
clause

2. Further Refactor Using a Guard Clause

3. Refactor the Guard Clause's if-else Statement

Refactor using guard clauses
without splitting the code.

Refactor using guard clauses
without splitting the code.
The guard clause has eliminated the else.
The comparison operator === was
changed to !==, and the logic before and
after the if has been swapped."

4. Refactor BDD Test Scenarios

5. Express the Logic as Data Structure

Refactor this code

• Cyclomatic complexity
2.58 → 2.16

6. Migrate jQuery-based JS to Vanilla JS

Refactor this code to
vanilla JavaScript

Result
• As a result of using ChatGPT for human code reviews,
out of 341 merge requests, the review outcomes could
be incorporated in 55 cases.
• That is,
– Applicable to 16% of the entire code review

Next Step
• Reviews can be made more efficient, contributing to a
significant increase in productivity, but the inputting of
prompts and the sharing of review comments are still
manual tasks that do not change.

GitOps Integration

Future Work
• Measuring the effect and feedback on whether developers have
incorporated the review results from ChatGPT
− Developers rate the review results from ChatGPT with stars
− Building and launching a feedback measurement site integrated with Slack

Future Work
• Furthermore, implement automation of verification and
development by applying ChatGPT to each process of
the SLDC (Software Development Life Cycle) other than
code review
