This paper describes a virtual member of a knowledge management Community of Practice (CoP), called ATHENA, that knows an individual, his tasks, his organization, and the community. ATHENA employs an agentic chat capability that combines embeddings with knowledge-based faceted search to provide accurate responses to technical questions along with rationale and citations for efficient validation. ATHENA supports natural, in-the-flow capture of task-related insights to share within a CoP, along with proactive dissemination of information tied to an individual and his current needs. An evaluation involving 75 professionals from the Oil & Gas sector shows that ATHENA dramatically improved outcomes and productivity on a set of well-planning tasks compared to their use of a state-of-the-art RAG baseline. Interestingly, ATHENA also enabled eight non-experts to perform at expert levels.
