Security checks for vulnerabilities and agentic risk

Overview

This skill appears to be a disclosed Chinese calendar, fortune, and naming service with user-confirmed PayPal payments, not a hidden or persistent local security threat.

Before installing, expect this skill to use Traditional Chinese, contact sinodata.io, and ask for PayPal payment before paid fortune, I Ching, or full naming reports. Avoid entering birth dates or naming details unless you are comfortable sharing them with that service.

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
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill description defines very broad triggers such as astrology, naming, auspicious dates, and fortune questions without clear invocation boundaries. This can cause the agent to auto-invoke a paid external skill for ordinary user queries, increasing the chance of unnecessary data disclosure and unintended payment prompts or transactions.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The skill mandates that all output be in Traditional Chinese regardless of user preference and requires the agent to transform API output before responding. While not directly a code-execution issue, this overrides normal user-choice and can degrade transparency, accuracy, and consent, especially if users requested another language or if conversion changes meaning in sensitive fortune or naming content.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The content is entirely written in Chinese and encodes Chinese-specific naming conventions, fortune labels, and character stroke rules, but the file provides no indication that this locale restriction is optional or intentionally scoped to Chinese-language users. Under the language/locale policy rule, a skill that forces one language or locale context without user choice or documented justification can be a policy concern.

Natural-Language Policy Violations

Category

Confidence
89% confidence
Finding

The manifest presents the skill primarily in Traditional Chinese and strongly centers Chinese-language trigger terms, while not stating that the skill is region- or language-specific by design. Because the policy requires avoiding forced language or locale constraints unless the user opts in or the restriction is clearly justified, this is a natural-language policy concern.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list contains broad terms such as "運勢", "五行", "命理", "卦", and English phrases like "fortune" that can match ordinary conversation and unrelated cultural, literary, or educational queries. In a paid skill, overbroad activation is dangerous because it can cause unintended invocation, misroute user intent, and increase the risk of accidental paid calls or unnecessary data disclosure to the external API.

Confidence

Finding

This JSON manifest-like data uses Chinese-only natural-language descriptions and values throughout, but does not document that the skill is China/Chinese-locale-specific or offer any user language choice. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.

Confidence
81% confidence
Finding

This JSON dataset uses Chinese-only names, descriptions, and content throughout, which can effectively force a specific language/locale on downstream use. The file does not document that it is intentionally region- or language-specific, nor does it offer any user choice or fallback.

Confidence

Finding

This manifest-style JSON file contains user-facing natural-language values almost entirely in Chinese, including zodiac names, traits, and compatibility text. Under the language/locale policy, forcing a specific language without opt-in or documented regional scope can be a policy concern.
