Packs entire repositories into single AI-friendly files in XML, Markdown, JSON, or plain text formats. Built specifically for feeding codebases to LLMs, with token counting so you know if you'll hit context limits (Claude Sonnet handles about 200K tokens). Respects .gitignore by default, strips comments from 20+ languages, and runs Secretlint to catch API keys and credentials before you accidentally share them. Works on local repos or remote GitHub URLs without cloning. The real use case is when you need to give an LLM full codebase context for debugging, security audits, or understanding unfamiliar code. Beats manually copying files or fighting with context window limits.
