legacy-code-summarizer
Produces comprehensive summaries and insights about legacy codebases to help understand unfamiliar code. Use when onboarding to a new project, planning refactoring efforts, assessing code for acquisition/migration, or generating documentation for undocumented systems. Analyzes architecture, dependencies, code quality issues, and test coverage. Creates high-level overviews with architecture diagrams, key components, entry points, and actionable insights for understanding and improving legacy code.

# Legacy Code Summarizer
Analyze and summarize legacy codebases to quickly understand their structure, quality, and improvement opportunities.
## Core Capabilities
This skill helps understand legacy code by:
1. **Mapping architecture** - Identify key components, layers, and relationships
2. **Analyzing dependencies** - Understand module coupling and import patterns
3. **Detecting quality issues** - Find code smells, technical debt, and outdated patterns
4. **Assessing test coverage** - Identify testing gaps and untested code
5. **Generating documentation** - Create actionable summaries for teams
