SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Working code often accumulates unnecessary complexity—deep nesting, long functions, unclear names, and duplication—that makes it harder to read, maintain, and extend. This Skill provides a disciplined process for simplifying code without changing its behavior. ## Core Features & Use Cases - Behavior-Preserving Refactoring: Applies five principles (preserve behavior, follow project conventions, prefer clarity, maintain balance, scope to changes) so every simplification keeps inputs, outputs, and error handling identical. - Pattern Detection Checklists: Identifies concrete simplification signals such as 3+ level nesting, 50+ line functions, nested ternaries, boolean flag parameters, dead code, and duplicated logic. - Language-Specific Guidance: Includes before/after examples for TypeScript, JavaScript, Python, and React/JSX, plus a verification checklist covering tests, linting, and diff cleanliness. - Use Case: After shipping a feature with passing tests, run this Skill to flatten nested conditionals into guard clauses, rename generic variables, and extract duplicated logic—producing a clean, reviewable diff. ## Quick Start Ask the agent to simplify the recently modified module using the code-simplification process while keeping all tests passing unchanged.

FAQPage Schema
How do I refactor code without changing its behavior?

Make one simplification at a time and run the full test suite after each change. Verify that inputs, outputs, side effects, and error behavior remain identical, and revert immediately if any test fails.

How to simplify deeply nested conditionals in Python or TypeScript?

Replace nested if blocks with guard clauses that handle error cases early and return immediately. This flattens the control flow so the main logic sits at the top indentation level, making it easier to follow.

When should I not simplify or refactor code?

Avoid simplifying code you do not yet understand, performance-critical paths where the simpler version is measurably slower, code about to be rewritten entirely, and code that is already clean and readable.

Should refactoring and feature changes go in the same pull request?

No. Refactoring changes should be submitted separately from feature or bug fix changes. Mixed PRs are harder to review, revert, and understand in version history.

What are the risks of over-simplifying code?

Over-simplification includes inlining named helpers, merging unrelated functions, removing abstractions that exist for testability, and optimizing for line count instead of comprehension. The goal is faster understanding, not fewer lines.
