name: code-metrics description: Analyze code quality metrics including lines of code by language, cyclomatic complexity (Python), function/class counts, comment ratios, and largest file rankings. Use when asked to analyze code quality, count lines of code, measure complexity, find the biggest files, get a project overview, or audit code metrics across a codebase. Supports Python, JavaScript, TypeScript, Go, Rust, Ruby, Java, C/C++, C#, Swift, Kotlin, PHP, Shell, Lua, R, and Scala.

Code Metrics

Analyze code quality and complexity metrics across your project. Supports 17+ languages.

Quick Start

# Analyze current project
python3 scripts/code_metrics.py

# Analyze specific directory
python3 scripts/code_metrics.py /path/to/project

# JSON output
python3 scripts/code_metrics.py --json

# Skip complexity analysis (faster)
python3 scripts/code_metrics.py --no-complexity

# Exclude additional directories
python3 scripts/code_metrics.py --exclude migrations fixtures

Metrics Provided

• Lines of Code — total, code, comments, blank lines per language
• Comment-to-code ratio — overall documentation density
• Function & class counts — per language
• Cyclomatic complexity — per-function for Python files (AST-based)
• Largest files — top N files ranked by code lines
• High complexity warnings — flags functions with complexity ≥5

Complexity Scale (Python)

Dependencies

• Python 3.8+ (stdlib only, no pip packages needed)

整体质量良好，代码简洁高效，无需安装额外依赖即可使用。该 Skill 覆盖的语言类型丰富，能快速生成代码度量报告，包含代码行数、注释比例、函数类数量和复杂度警告等实用信息。文档说明详细，上手容易。略有不足的是，部分高级语言的函数检测依赖简单的模式匹配，在复杂代码场景下可能存在误差，但日常使用完全足够。
