Safe Code Change

After a code change is made, find and fix affected tests before running validation.

Rules

• The code change is already done. Do not modify production code.
• Only update tests to match the new behavior, not the other way around.
• Do not reformat or lint-fix during test updates. Save that for validation.
• If a test change is ambiguous (unclear what the new expected behavior is), ask the user.

Step 1: Identify What Changed

git diff --name-only
git diff --stat

List the modified production files (ignore test files, configs, docs).
