A July 23 arXiv paper (2607.21019) presents HiMe, a locally deployable LLM agent platform for personal health insights that is compatible with real-time wearable data ecosystems across multiple devices. Its three design principles are treating the database as a core agent component rather than an accessory, jointly optimizing effectiveness and efficiency for cost, and processing real-time streams while maintaining long-term user modeling. It is a single-source academic release, but the database-as-core-component framing is a reusable pattern for any agent that must reason over a continuously appended time series rather than a static corpus.
