Workout Logger

Security checks for vulnerabilities and agentic risk

Overview

This is a simple workout-tracking skill whose data retention and broad triggers deserve user awareness but do not show malicious or purpose-mismatched behavior.

Install only if you are comfortable having workout history, exercise performance, and routine patterns remembered for progress tracking. Prefer a version that clearly explains where the data is stored, how long it is kept, and how to review or delete it.

A.I.G

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

Shadow Command Trigger

Medium
Category
Trigger Abuse
Confidence
79% confidence
Finding
The trigger "log workout" overlaps with the built-in verb "log," creating a risk that the platform may route users into this skill when they intended a generic logging action or another system command. In this skill's context, such confusion is more concerning because invocation can result in storing personal fitness history and changing long-term records.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The trigger phrase "gym session" is broad and plausibly appears in ordinary conversation, which can cause unintended invocation of the skill. Because this skill stores workout history over time, accidental activation could lead to unintentional collection or modification of sensitive health and fitness data.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill description emphasizes that it "remembers everything" and tracks progress over time, but it does not clearly disclose retention, persistence, or handling of workout history. Users may reveal sensitive health, routine, or location-adjacent behavioral information without understanding it will be stored, creating privacy and consent risks.
