Standard RAG systems use fixed, single-pass pipelines that fail on vague or multi-part queries. For applications requiring precise legal document retrieval, such as collective agreement queries in bilingual environments, this one-shot approach is insufficient. Agentic RAG introduces dynamic, multi-step reasoning: query rewriting, retrieval evaluation, self-reflection, and adaptive re-retrieval loops. Rather than hardcoding retrieval steps, the system autonomously decides how many iterations are needed to ground answers in verified sources. This seminar demonstrates this architecture applied to cross-lingual agreement document retrieval. The research bridges the gap between research-stage LLMs and production-ready systems for institutional governance. The results are built upon to deploy a fully functional open-source Agentic RAG retrieval system for the Laurentian University Faculty Association Collective Agreement.
