code-simplification
Simplifies code for clarity. Use when refactoring code for clarity without changing behavior. Use when code works but is harder to read, maintain, or extend than it should be. Use when reviewing code that has accumulated unnecessary complexity.
Why this skill is useful
Codifies a process for simplifying code that the AI could infer but now has a clear standard to follow.

What this skill does
Code Simplification Inspired by the Claude Code Simplifier plugin. Adapted here as a model-agnostic, process-driven skill for any AI coding agent. Overview Simplify code by reducing complexity while preserving exact behavior. The goal is not fewer lines — it's code that is easier to read, understand, modify, and debug. Every simplification must pass a simple test: "Would a new team member understand this faster than the original?" When to Use After a feature is working and tests pass, but the implementation feels heavier than it needs to be During code review when readability or complexity issues are flagged When you encounter deeply nested logic, long functions, or unclear names When refactoring code written under time pressure When consolidating related logic scattered across files After merging changes that introduced duplication or inconsistency When NOT to use: Code is already clean and readable — don't simplify for the sake of it You don't understand what the code does yet — comprehend before you simplify The code is performance-critical and the "simpler" version would be measurably slower You're about to rewrite the module entirely — simplifying throwaway code wastes effort The Five Principles 1. Preserve Behavior Exactly Don't change what the code does — only how it expresses it. All inputs, outputs, side effects, error behavior, and edge cases must remain identical. If you're not sure a simplification preserves behavior, don't make it. 2. Follow Project Conventions Simplification means making code more consistent with the codebase, not imposing external preferences. Before simplifying: Simplification that breaks project consistency is not simplification — it's churn. 3. Prefer Clarity Over Cleverness Explicit code is better than compact code when the compact version requires a mental pause to parse. 4. Maintain Balance Simplification has a failure mode: over-simplification. …
