Information Hiding Review Lens

When invoked with $ARGUMENTS, focus the analysis on the specified file or module. Read the target code first, then apply the checks below.

Evaluate whether modules encapsulate design decisions effectively.

When to Apply

• Reviewing module boundaries or class decomposition decisions
• When multiple modules change together for single-decision changes
• When private fields have matching getters and setters
• When modules are organized around execution steps (read/process/write)
• When a format, protocol, or representation appears in multiple places

Core Principles

Knowledge Ownership Test

For every design decision in the code (data format, algorithm choice, protocol, storage representation):
