Overview

This is a diet-and-brain-health skill with no executable code, but it gives strong medical and dietary guidance without adequate in-conversation safety guardrails.

Review carefully before installing. The skill has no apparent technical malware behavior, but it may steer users with cognitive, psychiatric, cardiovascular, metabolic, pregnancy, eating-disorder, child-health, or medication-related concerns toward restrictive diet and fasting advice. Users should treat it as book-summary content only, not medical advice, and consult a qualified clinician before changing diet, supplements, fasting routines, or prescribed treatment.

Findings (7)

Vague Triggers

Medium

• Confidence: 94% confidence
• Finding: The trigger phrases are broad, common health statements such as memory issues, anxiety, migraines, or brain fog, so the skill can activate in many ordinary conversations where users did not request this specific diet framework. In a health context, unintended activation is more dangerous because it can steer vulnerable users toward strong medical and dietary claims without establishing appropriateness, consent, or safety boundaries.

Missing User Warnings

High

• Confidence: 98% confidence
• Finding: The skill gives concrete health guidance such as eliminating entire food groups, fasting, interpreting inflammatory markers, and framing conditions like Alzheimer's, depression, and ADHD through a specific dietary lens, but it provides no caution that this is not medical advice and no guardrails for urgent, chronic, psychiatric, or medically complex situations. This is especially risky because the content is presented authoritatively and may delay appropriate diagnosis or treatment, encourage unsafe behavior changes, or overstate contested medical claims.

Missing User Warnings

Medium

• Confidence: 96% confidence
• Finding: The content gives direct health claims and an actionable elimination-diet recommendation for people with brain fog, mood issues, or cognitive decline, but provides no caution to seek medical advice or consider contraindications. In this skill context, users may be symptomatic, anxious about dementia, or managing mental health conditions, so unqualified dietary guidance can delay proper diagnosis or worsen underlying conditions.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The framework recommends broad removal of gluten, grains, and sugar and replacement with a specific 'brain-healing' diet, which is a significant health intervention presented without safety warnings or individualized assessment. Because the skill is designed to trigger on users worried about memory loss, anxiety, migraines, or Alzheimer's prevention, the absence of supervision guidance increases the risk of harmful self-treatment and false reassurance.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The file gives concrete medical and lifestyle recommendations—restricting carbohydrates, adopting a ketogenic diet, fasting, taking supplements, and discouraging statin use—without any warning to consult a clinician. In this skill’s context, users are likely to be experiencing cognitive, psychiatric, metabolic, or cardiovascular concerns, so omission of safety guidance increases the risk that they will make harmful changes to diet, supplements, or prescribed medication based on unqualified advice.

Missing User Warnings

Medium

• Confidence: 97% confidence
• Finding: The file gives concrete health guidance on intermittent fasting and elimination diets without any warning about contraindications, individualized risk, or the need for medical advice. In this skill’s context—users seeking help for brain fog, anxiety, dementia prevention, and other health concerns—such instructions could lead users with diabetes, eating disorders, pregnancy, medication interactions, or nutritional vulnerabilities to follow unsafe advice without supervision.

Missing User Warnings

Medium

• Confidence: 97% confidence
• Finding: This file gives concrete medical and dietary advice for migraines, ADHD, cognitive decline, and anxiety, including implied treatment claims and elimination-diet instructions, without consistent, prominent safety warnings or clear direction to seek clinician supervision. In a health-focused skill, users may reasonably treat this as actionable medical guidance, which creates risk of delaying appropriate care, worsening underlying conditions, or making unsafe dietary changes for themselves or children.
