Ask Claude to Standardize Inconsistent Patterns Across Your Codebase

Codebases written by multiple developers over time accumulate inconsistencies — not bugs, just different ways of doing the same thing. Claude reads them all, identifies the best pattern, and standardizes the rest.

"Some controllers return JSON with response(), others with 
JsonResponse::class, others with ->toJson(). Pick the best 
approach and standardize all of them."

Claude surveys every instance, identifies which pattern is most common or most correct, and updates the outliers — preserving behavior while making the code consistent.

Common inconsistencies Claude can fix:

# Response formatting
"Standardize how all API endpoints format success and error responses"

# Error handling approaches
"Some services throw exceptions, others return null, others return 
Result objects. Pick one approach and standardize."

# Date handling
"Standardize all date formatting — some use Carbon, some use DateTime, 
some use strtotime. Pick one."

# Configuration access
"Some code uses env() directly, others use config(). Standardize 
to always use config() with env() only in config files."

# Import styles
"Some files use fully qualified class names, others use imports. 
Standardize to always use imports."

Claude identifies the pattern that's most common, most correct, or most aligned with your framework's conventions — then applies it everywhere.

This is different from linting (which catches syntax) and different from refactoring (which changes structure). Standardization keeps the logic identical but makes the expression of that logic consistent across the project.

Inconsistency is friction — every developer who reads the code has to learn two ways of doing the same thing. Let Claude pick the best way and apply it everywhere.
