A personal health agent becomes unsafe the moment its interface is allowed to sound like a clinician. The useful object here is narrower: non-medical data architecture with inspectable source rows and a hard refuse list.
What is a personal health agent? On this site: a non-medical system that organises signals you already have, flags change against a named baseline, and surfaces questions for a professional. It does not diagnose. It does not prescribe. It does not replace care. If you need care or have a health concern, consult a qualified healthcare professional; this article is not medical advice.
What is an AI agent? still applies. A health wrapper without a charter is a demo that can scare you.
The refuse list
Write these as ceilings, not as vibes.
- No diagnosis language.
- No dose, treatment protocol, or “you should start.”
- No alteration or override of a clinician’s plan.
- No emergency monitoring and no claim that silence means you are well.
- Every flagged change points at a row you can open: device, timestamp, metric, baseline. What is an evidence ledger? is that discipline in other clothes.
If the system answers as a doctor, it is already the wrong worker.
AGENT, named and unfinished
AI Agents for Personal Health uses AGENT: Assemble, Generate, Evaluate, Notify, Tune. Assemble the sources. Generate a structured, queryable signal pipeline, not a verdict. Evaluate correlations and deviations with explicit limits. Notify a human about a data change, never a diagnosis. Tune data-quality and change-detection settings with a named reviewer; silence is not medical reassurance. The book is in design and not for sale.
Collision control
Not a clinician. Not a second opinion. Not “optimise your biology” as treatment.
Not a consumer wellness coach. Fluency about sleep is still fluency. The test is the row.
Not the startup-strategy agent. AI Agents for Startup Strategy is live. This book is not. Do not mix the charters.
What this page is not
It is not medical advice. It is not a wearable setup guide. It is not a study.
Write the refuse list and one baseline. If the worker cannot show the row, unplug it.
