Managing software dependencies is a crucial maintenance task in software development and is becoming a rapidly growing research field, especially in light of the significant increase in software supply chain attacks. Specialized expertise and substantial developer effort are required to fully comprehend dependencies and reveal hidden properties about the dependencies (e.g., number of dependencies, dependency chains, depth of dependencies). Recent advancements in Large Language Models (LLMs) allow the retrieval of information from various data sources for response generation, thus providing a new opportunity to uniquely manage software dependencies. To highlight the potential of this technology, we present~\tool, a proof-of-concept Retrieval Augmented Generation (RAG) approach that constructs direct and transitive dependencies of software packages as a Knowledge Graph (KG) in four popular software ecosystems. DepsRAG can answer user questions about software dependencies by automatically generating necessary queries to retrieve information from the KG, and then augmenting the input of LLMs with the retrieved information. DepsRAG can also perform Web search to answer questions that the LLM cannot directly answer via the KG. We identify tangible benefits that DepsRAG can offer and discuss its limitations.
