This tool allows you to search for GitHub repositories by keyword, clone them, and analyze their file structure for specific patterns (such as Cursor rules). It generates a Markdown report summarizing the findings.

Run the script with tsx or Node.js:

tsx github-analyzer.ts <search-query> [file-patterns...] [options]

tsx github-analyzer.ts "dotfiles" "*.zsh" "*.bash" --limit 15
tsx github-analyzer.ts "claude.md" --limit 10
tsx github-analyzer.ts "cursor rules" ".cursor/rules" "cursor-rules" --limit 20

• --limit <number>: Number of repositories to analyze (default: 10)
• --help: Show usage instructions

• Searches GitHub for repositories matching your query (using the GitHub CLI gh)
• Clones each repository into a temporary directory
• Recursively scans files, looking for matches to your file patterns (supports globs like *.mdc or directory names)
• Analyzes file types, structure, and special files (like README.md, package.json)
• Generates a Markdown report summarizing the results
• Prints the location of the temporary directory where all repositories are checked out

After running, the script prints the path to the temporary directory (e.g., /var/folders/.../T/github-analysis-<timestamp>). All cloned repositories are stored there, in subdirectories named <owner>-<repo>. The files remain available for further inspection until you manually delete them or your system cleans up the temp directory.

• Node.js (18+ recommended)
• tsx (for running TypeScript directly)
• GitHub CLI (gh) (must be authenticated)

• The script uses Node.js built-in modules (fs, path, os, child_process).
• If you see TypeScript errors about missing types, install Node types:

  npm install --save-dev @types/node

• The script is designed for CLI use, but you can also import and use the GitHubRepoAnalyzer class programmatically.
