Code Simplifier Skill

Simplify and refine code for clarity, consistency, and maintainability.

Usage

/code-simplifier # Simplify recently modified files /code-simplifier path/to/file.ts # Simplify specific file /code-simplifier --scope=function # Focus on function-level simplification

What It Does

• Analyzes code for unnecessary complexity

• Identifies opportunities to simplify without changing behavior

• Applies KISS, DRY, and YAGNI principles

• Preserves all existing functionality

Simplification Targets

• Redundant code paths

• Over-engineered abstractions

• Unnecessary comments (self-documenting code preferred)

• Complex conditionals that can be flattened

• Verbose patterns that have simpler alternatives

Execution

Use the code-simplifier:code-simplifier subagent:

Task(subagent_type="code-simplifier:code-simplifier", prompt="Review and simplify [target files]")

Examples

Before:

function getData() { const result = fetchData(); if (result !== null && result !== undefined) { return result; } else { return null; } }

After:

function getData() { return fetchData() ?? null; }
