depresearch
Research any open-source repository from the command line using AI agents. Ask a question, get back a detailed walkthrough with file paths, line numbers, and code snippets.
When to use
- You need to understand how a feature works in an external open-source repo
- You want to analyze a library's internals without manually cloning and reading the source
- You're working in a coding assistant and need context about a foreign codebase
