SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables developers and reviewers to perform read-only code analysis to understand structure, patterns, and complexity without risking accidental changes.

Core Features & Use Cases

  • Read-Only Analysis: Inspect file and directory structure, module relationships, and import/export patterns without modifying code.
  • Pattern & Complexity Insights: Identify design patterns, anti-patterns, and estimate function lengths and cyclomatic complexity.
  • Security & Quality Review: Detect potential risk signals (e.g., hardcoded secrets patterns) without writing to files.
  • Use Case: Use during code reviews, refactoring planning, or when learning a new codebase.

Quick Start

Analyze a repository by using Glob to locate source files, Grep to find patterns, and Read to inspect contents. Then generate a read-only report summarizing structure, patterns, and potential improvement areas.

Frequently Asked Questions about code-analyzer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I analyze code structure and patterns without modifying files?▼

Read-only code analysis lets you inspect file structure, module relationships, and design patterns using grep and glob operations to identify complexity and anti-patterns across your codebase safely.

Can I use code analysis during code reviews to spot potential issues?▼

Yes, read-only analysis is designed for code reviews to detect risk signals like hardcoded secrets patterns, cyclomatic complexity issues, and structural problems without touching your code.

What's the best way to understand a new codebase quickly?▼

Use read-only analysis to map file and directory structure, trace import/export patterns, and identify design patterns, giving you a comprehensive overview without risking accidental changes.

Does read-only code analysis work across different programming languages?▼

Yes, this approach analyzes codebases across languages and projects by inspecting structure and patterns at the file level, making it language-agnostic for multi-language repositories.

How does this help with refactoring planning?▼

Read-only analysis estimates function lengths and complexity, identifies anti-patterns, and highlights improvement areas, providing a foundation for safe refactoring decisions before making changes.

What operations are restricted in read-only code analysis?▼

Read-only analysis prohibits edits, file writes, and code execution, restricting operations to reading file contents, grep pattern matching, and glob file location to ensure non-destructive inspection.
