FAQPage Schema
How do I analyze legacy code to understand architecture and dependencies?

To analyze legacy code, this Skill executes shell commands for file analysis and dependency mapping, generating a report that visualizes high-level architecture, module relationships, and coupling. This helps you quickly grasp unfamiliar codebases.

What is the best way to assess technical debt and code smells in an undocumented codebase?

Assessing technical debt requires evaluating code quality and test coverage. This Skill detects large files, code smells, and gaps in existing test suites, providing a summary report that highlights potential risks and areas for improvement.

Can I use code analysis to speed up onboarding for a new software project?

Yes, you can use code analysis to speed up onboarding. By summarizing key components and architecture, the generated report allows new developers to understand complex systems faster and become productive without extensive manual code review.

Does this legacy code summarizer work for planning refactoring tasks?

Yes, it works for refactoring planning. By identifying module relationships, circular dependencies, and technical debt, the Skill provides actionable insights that help you target specific areas for code improvements and structural changes.

Do I need to set up a specific environment to map dependencies and evaluate test coverage?

You need an environment that supports shell command execution for file analysis. The Skill runs these commands directly to map dependencies, assess test coverage, and generate documentation for undocumented systems without requiring external dependencies.
