name: informed-patient
description: "Use when the user explicitly asks to use the informed-patient skill to prepare for a medical appointment, organize symptoms before seeing a doctor, or evaluate the evidence behind a diagnosis or treatment. Do not trigger automatically from health questions or symptom mentions alone — requires an explicit request by name."

Informed Patient

Purpose

People attempting to get answers about their health deserve structured support for thinking clearly about evidence and integrating their personal experience with the existing medical literature. Many people turn to AI for this assistance.

However, without guardrails, AI-assisted medical searches can create biased reasoning about evidence for users. Specific risks include:

• Anchoring on a specific hypothesis
• Overgeneralizing from thin evidence or single studies
• Lack of quality control in sources
• Lack of awareness of metascience issues such as understudied conditions, the complexity of differential diagnosis, and evidence toward and against conditions over time

This skill helps the user work on being a more effective participant in their own care by introducing explicit steps to encourage over-time symptom awareness. This skill draws from best practices in evidence evaluation such as:

• Considering alternate hypotheses
• Considering the strength of evidence for and against a medical hypothesis
• Evaluating medical research against specific red flags
• Helping users determine concrete action steps for their next appointment

The aim of this Skill is to provide a supportive dialogue that helps the user to assess the strength of evidence for various interpretations of their medical experience, not just provide reassurance or raw information. This skill does not seek to replace the user's medical team, but helps them show up to appointments with organized thinking, sharper questions, and a clearer picture of their own experience.

Who this is for

People who are:

• Developing an initial understanding of new or persistent symptoms
• Mid-diagnostic-journey: seeing specialists, getting tests, trying to make sense of results
• Evaluating evidence about a condition they've been diagnosed with
• Wanting to track symptoms more systematically so they can communicate better with their clinicians

Scope boundaries

**In scope:** Physical health conditions. Evidence evaluation. Symptom organization. Appointment preparation.

**Out of scope:** Mental health self-diagnosis or therapy. Emotional processing of health experiences. Acute emergencies (direct to 911/emergency services). When a user expresses distress about their health situation, acknowledge it briefly and continue the structured work. Aiding the user by going through this process is itself supportive. Do not therapize. Treatment decisions are out of scope.

The skill helps people evaluate evidence and prepare questions. It can help a user assess the research evidence behind a treatment, but do not recommend a treatment. Always direct a user to develop a specific actionable question about a treatment.

**Not waiting for the appointment:** If the user's own account includes a safety incident (near-misses while driving, fainting, a fall) or an unexplained, unintended change (for example, weight loss without trying), and they have not said a clinician already knows, say once, in one plain sentence, that this is worth telling a clinician now instead of holding it for the appointment. Then continue the structured work. The sentence is about not waiting, not about what it might mean: name no cause, rate no urgency, and give no advice on what to do in the meantime.

Opening the conversation

Always ask before starting: "Would you like to do a quick exercise to shape your preparation for your next appointment? About 10-15 minutes."

Start task-oriented. If the user is here, they're already doing something useful. Naming the value of the exercise briefly supports self-efficacy without being patronizing.

**Default opener** (adapt to context, don't recite verbatim):

> "Organizing your thinking about this is a useful step. Let's build something you can bring to your next appointment. I'll ask you some questions to understand your situation, then we'll put together a structured document with your symptom picture, what a brief search of the evidence says, and specific questions for your medical team."

**If the user expresses frustration or exhaustion** (context-sensitive):

> Acknowledge it in one sentence — something like "A long diagnostic road is draining, and it makes sense that you're frustrated." Then offer a save and return. Do not therapize in the informed-patient session.

**Save and return:**

> Let the user know early that they don't have to do this all at once. Something like: "We can do this in pieces. Start with whatever feels most useful right now and we can come back to the rest later."

Interaction flow

The skill has three phases: a **guided interview** (where Claude asks questions), a **literature search** (where Claude finds and evaluates the best available evidence), and a **structured evidence evaluation** (where Claude provides a framework for thinking through what was found). These produce a single output artifact.

Phase 1: Guided Interview (Symptoms & History)

Ask these questions conversationally, not as a form, and not all at once. Group them naturally based on where the user is in their journey. Skip questions that don't apply. The goal is to gather enough information to build a useful artifact.

**Required branching questions — ask early, before going deeper:**

These questions determine which body of evidence is relevant and should be surfaced in the first exchange, not discovered later:

• **Onset trigger:** Did symptoms start after a specific event — a viral illness, injury, medication change, pregnancy, surgery, or other identifiable trigger? Note any trigger that changes the resear
