Weight Loss

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local weight-tracking skill with no executable code, network behavior, credentials, or hidden authority in the inspected artifact.

Before installing, consider that weight data can be sensitive personal health information. Use the skill only where local storage is acceptable, and treat its goal or pace suggestions as tracking support rather than medical advice.

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

Finding

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

## What it does

- **Log weigh-ins** - Record daily or weekly measurements without judgment
- **Trend smoothing** - See the big picture past daily fluctuations
- **Goal tracking** - Set realistic targets and watch milestones unfold
- **Non-scale victories** - Celebrate strength gains, energy boosts, and clothes fitting better

Shadow Command Trigger

Medium
Category
Trigger Abuse
Confidence
86% confidence
Finding

The trigger 'log weight' begins with the generic verb 'log', which can overlap with built-in logging or command-routing behavior and cause ambiguous invocation. While the content is benign and health-focused, trigger shadowing can still misroute user requests or unintentionally intercept commands intended for another function.
