Probe: AI Agent Context Engine (github.com)

probe is a newly launched CLI tool and server designed to enhance AI agents by providing instant access to relevant project documentation, code, and specifications. Unlike traditional AI coding assistants that take time to sift through project files, probe indexes diverse file types—Markdown, PDFs, and plain text—using advanced machine learning models from ZeroEntropy. This results in sub-second query responses that effectively combine documentation and source code, enabling developers to quickly retrieve context, such as authentication flow or architectural decisions, without the delays encountered in large projects. This tool is significant for the AI/ML community as it streamlines the development process by reducing the time spent searching for information, thus enhancing productivity. The underlying technology involves hybrid retrieval methods, where queries undergo parallel semantic vector and keyword searches, with results reranked for precision using a neural cross-encoder model. The results are not only fast but also come with citations and relevance scores, ensuring that developers receive the most pertinent information. As a result, probe positions itself as a critical addition to the toolkit of AI development, improving project context utilization while supporting a seamless integration into existing workflows.
