What is XERJ?
XERJ.ai indexes source code with syntax-aware parsing to extract symbols, definitions, and implementation bodies for fast, targeted retrieval. It clones and groups reference repositories by problem domain, builds incremental indices, and exposes a search API compatible with LLM agent workflows. Retrieval combines lexical ranking and vector recall with explicit fallbacks, returning precise code excerpts and associated license metadata for citation. Agents query the index before generating code to read real implementations and runtime contracts, reducing guess-and-retry loops and the volume of model output required. Indexing covers multiple languages and updates incrementally as reference sources change. Integration uses standard search endpoints and simple commands to fit into existing toolchains, and results supply file locations and contextual passages to guide adaptation while respecting licence constraints.
