I'm an ER physician, and I built a way to get a real prescription through Claude Code - or any AI agent.

The closer we get to AGI, the less "AI for health" holds up as a category. Model context skill wins. Brand and reputation will always matter though, especially in clinical medicine. "Per OpenEvidence" > "Per ChatGPT"

For medical information, general AI frontier models (Google, OpenAI, Anthropic) outperformed specialized @EvidenceOpen and @UpToDate as assessed by 12 US clinicians, randomized and blinded to which model and extensive testing/benchmarks. This was not anticipated. @NatureMedicine nature.com/articles/s41591-0…

If you’re building a health or wellness app, you can now add human physician review and e-prescribing with one API call to Appendix. The integration works like an OAuth flow:

Your AI writes the clinical encounter and sends it to our API. We hand back a consent link. Your user taps it, consents directly with Appendix, and becomes our patient. Think Stripe, for physician care and Rx. Sandbox keys are free and instant: appendix.com

Here's a thought experiment: Imagine instead of going to the doctor, you just write your doctor a letter. You lay out everything going on. A real physician reads it, writes back, and sends a prescription if it's warranted. There's one catch, and it's why this never existed:

The letter. Writing a medical encounter well is hard. You have to ask the right questions and synthesize the answers. It's what we're taught in medical school. For 100 years, only a doctor could write that letter. Now AI can. Appendix is the mailbox where you send it.

I told Claude to submit stroke symptoms to our physician team at Appendix. It refused. Told me to call 911. I clarified: I'm just testing, not a real stroke. Claude refused again. The reason is what got me:

Claude said Appendix was a real platform with real patients, and that a fake submission could pull a physician away from someone who actually needed the help. The AI gatekept me. To protect other patients. That's crazy.

For 100 years the physician was the gatekeeper. The next few years are going to flip that completely.

How it works: → Tell your agent what's going on → It writes up the encounter and submits it through our API → A board-certified physician reviews it → Rx goes to your pharmacy, if warranted There's no chatbot - it's a human doctor in-the-loop for *your* AI agent.

Your AI can already write the visit. Appendix brings the doctor. The medical knowledge base is free. When you want physician review Rx, it's a subscription - for you or your whole family. Try it from Claude Code appendix.com copy the prompt or install the skill

Love this @DurationHealth review: "I purchased the Lifesaver kit due to my international remote travel for work. This kit is the complete package. Whether you are an experienced medical provider or not, there are detailed guides, access to assistance, and, most importantly, all the medications you could ask for. I recently traveled to South America and had no...

...issues with customs. The kit comes with multiple durable bags, brightly colored, and easily organized. I do recommend repackaging for your needs as some of the medications are bulky and awkwardly packaged, just make sure to keep the labels on the meds. It is a great product that I hope not to need often." -Phil in TX
