Loot Reward Celebrator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a low-risk reward-planning helper that stays aligned with its stated purpose and does not request sensitive access.

Before installing, understand that this skill formats completed tasks into reward suggestions and may activate for general milestone-celebration requests. It does not make purchases, handle payments, store records, or access private accounts based on the inspected files.

  • 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

Without declared permissions the skill's intent is opaque and cannot be validated.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The 'When to use' section and example prompts include generic phrases such as 'celebrate a finished task or milestone' and 'What is a good reward after finishing this project?', which overlap with ordinary conversation and are not paired with explicit exclusion conditions. Because the file does not define narrow trigger phrases or negative examples, the activation scope is ambiguous for a manifest-like markdown skill description.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The file includes 'Chinese name: 战利品奖励庆祝.' as a natural-language locale-specific element, but does not state that language selection is optional or user-driven. Under the policy, fixed language or locale choices can be problematic when not offered as an opt-in or otherwise justified.
