### Avoid Unnecessary Changes

When fixing a bug or adding a feature, don't modify code unrelated to your
task. Unnecessary changes make PRs harder to review and can introduce
regressions.

**Don't reword existing comments or code** unless the change is directly
motivated by your task. Rewording comments to be shorter or "cleaner" wastes
reviewer time and clutters the diff.

**Don't delete existing comments** that explain non-obvious behavior. These
comments preserve important context about why code works a certain way.

**When adding tests for new behavior**, add new test cases instead of modifying
existing ones. This preserves coverage for the original behavior and makes it
clear what the new test covers.
