The tool combines static analysis (code metrics, architecture detection, dependency extraction) with AI-powered insights via GitHub Copilot CLI to deliver professional-grade repository assessments.</p> <h3> Key Features: </h3> <p><strong>Automatic Detection:</strong> Language, build tool (Maven/Gradle), packaging type, test coverage, CI presence<br> <strong>Architecture Analysis:</strong> Extracts project modules, packages, and generates Mermaid diagrams showing actual project structure (not hardcoded templates)<br> <strong>Metrics Collection:</strong> Calculates code complexity, test-to-code ratios, test coverage percentages<br> <strong>External Dependency Detection:</strong> Uses pattern matching and Maven artifact scanning to identify integrations (databases, messaging, cloud services)<br> <strong>AI-Enhanced Reports:</strong> Leverages GitHub Copilot CLI to analyze codebase metrics and generate high-level technical summaries<br> <strong>Markdown Reports:</strong> Produces clean, professional reports with structured findings and recommendations</p> <h3> Use Cases </h3> <ul> <li> <strong>New to a project?</strong> Understand architecture, test coverage, and dependencies in minutes</li> <li> <strong>Need to fix/enhance code?</strong> Get full context before diving into unfamiliar code</li> <li> <strong>Managing multiple repos?</strong> Standardize insights and track quality across your organization</li> <li> <strong>Tracking tech quality?</strong> Assess architecture, test coverage, and tech debt across your portfolio</li> </ul> <p><a href="https://github.com/rb2-projects/copilot-repo-insights" rel="noopener noreferrer">Link to repo</a></p> <h2> Demo </h2> <p><a href="https://youtu.be/ZSKlIRAsxm8" rel="noopener noreferrer"> https://youtu.be/ZSKlIRAsxm8 </a></p> <h2> My Experience with GitHub Copilot CLI </h2> devchallenge githubchallenge cli githubcopilot
