code-commenter

Write rationale-focused comments that capture the intent, constraints, and non-obvious decisions behind your code rather than restating obvious behavior. This approach ensures comments remain maintainable and help developers understand why specific implementation choices were made.

The best way to document complex business rules and fragile workarounds is to add concise, durable comments that capture the reasoning behind the implementation. Documenting the specific constraints and non-obvious decisions ensures the knowledge is preserved during future source code review and refactoring.

You clean up stale or redundant comments during code refactoring by evaluating existing documentation against current implementation logic and removing any comments that are misleading or simply restate obvious behavior. This cleanup process keeps your API documentation and source code maintainable.

You should add rationale comments to API documentation when public methods, classes, or complex interfaces contain non-obvious implementation decisions, performance tradeoffs, or bug workarounds. Writing clear docstrings that explain these constraints ensures your API remains understandable for other developers.

No, you do not need external dependencies or specific tools to write maintainable code comments. This approach requires no external dependencies and focuses purely on documenting rationale, constraints, and non-obvious implementation decisions directly within your source code.

Intent-focused code comments differ from standard implementation comments by explaining why an implementation choice was made rather than how the code works. They prioritize capturing rationale, constraints, and non-obvious decisions to improve readability without duplicating obvious behavioral details.
