Fasting Tracker

Security checks for vulnerabilities and agentic risk

Overview

This fasting skill is mostly coherent, but it should be reviewed because it gives health-related fasting guidance with overconfident milestone claims and describes background tracking without enough user control detail.

Review this skill carefully before installing. It does not appear to contain malware or exfiltration code, but users should not treat its fasting milestones or extended-fast recommendations as medical advice. Avoid using it for prolonged fasts, medical conditions, pregnancy, eating-disorder history, diabetes, or medication-sensitive situations without qualified medical guidance, and confirm any background tracking or reminders can be disabled and removed.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (3)

Shadow Command Trigger

Medium

Category: Trigger Abuse
Confidence: 70% confidence
Finding: Shadow Command Trigger: 'start fast' conflicts with built-in command 'start'

Missing User Warnings

Medium

Confidence: 92% confidence
Finding: The skill encourages fasting actions, including extended fasts and background tracking, without a prominent upfront safety warning or clear gating for higher-risk use. In a health-related context, omission of risk disclosures can lead users—especially beginners or people with contraindications—to follow potentially unsafe fasting routines with undue confidence.

Natural-Language Policy Violations

Medium

Confidence: 95% confidence
Finding: The metabolic timeline presents claims such as autophagy activation, immune reset, and cellular regeneration as concrete milestone effects tied to exact durations, which overstates medical certainty. Users may rely on these claims as health guidance and push into longer fasting durations based on misleading or insufficiently qualified physiological promises.
