Security checks for vulnerabilities and agentic risk

Overview

This is a simple greeting skill that only shapes greeting responses and does not request sensitive access or run code.

Installing this should be safe for ordinary use. Be aware it may activate on casual greetings more often than a narrowly scoped skill would, but it does not ask to read private data, modify files, install software, or call external services.

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

Vague Triggers

Medium
Confidence
96% confidence
Finding
The trigger scope is intentionally broad enough to match extremely common greetings, which can cause this skill to activate in many ordinary conversations where the user may not specifically want this skill. While the skill’s behavior is low risk because it only returns a greeting, overbroad activation can still create routing ambiguity, interfere with more appropriate skills, and make prompt-selection behavior less predictable.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The usage section expands activation with open-ended examples like 'what's up' and general session-start greetings, which increases ambiguity and the chance of accidental invocation. In isolation this is not highly dangerous, but in an agentic system ambiguous trigger definitions can degrade control over which skill is selected and create unintended behavior chaining.
