A small change can: +- Break assumptions in other parts of the file +- Invalidate comments or documentation +- Introduce inconsistencies with adjacent code +- Break callers that depend on previous behavior +- Create edge cases in previously working code + +### How to Review Full Context + +1. **Read the complete file from top to bottom** + - Understand the module's purpose + - Identify all exported functions/classes + - Note internal helper functions + - Check imports and dependencies + +2. **For each changed function:** + - Read ALL functions in the same file + - Read ALL callers of this function (use grep/search) + - Read ALL functions this code calls + - Check if changes affect other methods in the same class + +3. **Check for ripple effects:** + - Does the change break other functions in this file? + - Do other functions depend on the old behavior? + - Are there assumptions in comments that are now false? + - Do tests in the same file need updates? + +4. **Verify consistency across file:** + - Are similar operations handled consistently? + - Do error patterns match across functions? + - Is validation applied uniformly? + - Do naming conventions remain consistent? + +### Example: Context-Dependent Issue + +```typescript +// Changed lines only (looks fine): +function updateUserEmail(userId: string, newEmail: string) { + - return db.users.update(userId, { email: newEmail }); + + if (!isValidEmail(newEmail)) throw new Error("Invalid email"); + + return db.users.update(userId, { email: newEmail }); +} + +// But reading adjacent function reveals issue: +function updateUserProfile(userId: string, profile: Profile) { + // This function ALSO updates email but doesn't have the validation! + return db.users.update(userId, profile); // ⚠️ Inconsistency! +} + +// Full context analysis catches: +// 1. Validation added to updateUserEmail but not updateUserProfile +// 2. Two functions doing similar things differently +// 3. Email validation should be in BOTH or in db.users.update +``` + +**When reviewing, always ask:** +- "What else in this file touches the same data?" +- "Are there other code paths that need the same fix?" +- "Does this change introduce inconsistency?" + +--- + +## Review Checklist Priority + +Focus on these areas in order of importance: + +### 1.
