osgrep provides natural-language semantic search over code repositories, designed to be integrated into AI coding agents. It indexes repositories locally using ColBERT embeddings via onnxruntime-node, automatically isolating each repo with its own index. Features include role detection distinguishing ORCHESTRATION from DEFINITION patterns, call graph tracing for dependency mapping, and agent-native output formats with symbols and roles. The tool runs as a local daemon service and falls back to on-demand indexing when the server is not running.
