Code Simplifier

After completing code changes, review your work for opportunities to simplify and improve.

What to Check

Reuse

• Are there existing utilities, helpers, or patterns in the codebase that do the same thing?
• Did you duplicate logic that already exists elsewhere?
• Can any new helpers be consolidated with existing ones?

Quality

• Is the code consistent with surrounding patterns and conventions?
• Are variable/function names clear and descriptive?
• Is control flow straightforward? Flatten nested conditionals with guard clauses and early returns.
• Are there unnecessary abstractions or over-engineering?
• Is error handling appropriate — not too much, not too little?

Efficiency

• Are there redundant operations (duplicate API calls, repeated computations, unnecessary loops)?
• Could any logic be simplified with built-in language features or standard library tools?
• Are imports clean and minimal?

Process

1. Review all files you modified in this session
2. For each file, check against the criteria above
3. Fix any issues found — do not just flag them
4. Keep changes minimal and focused: only simplify, do not add features or refactor beyond what's needed

Scope

• Focus on code you wrote or modified in this session
• Do not refactor unrelated code
• Preserve all existing functionality — simplification must not change behavior
