Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local utility that calculates Swatch Internet Time and does not show evidence of hidden access, persistence, data collection, or destructive behavior.

Before installing, be aware that broad phrases like '@ time' or 'current beats' may invoke the skill unexpectedly in ordinary chat. Security-wise, the reviewed artifact only needs python3 and performs local time calculation.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger phrase "@ time" is overly broad and can match many unrelated user requests involving the @ symbol or general time queries. In an agent environment, this can cause unintended skill activation, leading to incorrect routing, unexpected command execution, or interference with higher-priority skills.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger "@ time" is highly ambiguous because "@" is common syntax in usernames, email-like text, and casual notation, while "time" is a generic term. In a trigger-based agent system, this ambiguity increases the chance of unintended invocation or misrouting from unrelated user input, making it more dangerous than the other phrase despite the harmless skill behavior.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

The phrase "Swatch time" is somewhat ambiguous because users may refer to the brand, watches, or general timekeeping rather than Internet Time beats specifically. This ambiguity can produce false activations, though the consequence is limited because the skill itself performs only local time formatting.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.

Finding

The trigger phrase "current beats" is somewhat broad and could be matched during ordinary conversation about music, exercise, or general status rather than an explicit request for Swatch Internet Time. This can cause accidental invocation of the skill, leading to incorrect routing or user confusion, though the skill itself appears low-risk and only returns time data.
