Security checks for vulnerabilities and agentic risk

Overview

This is a small prank math skill with no code execution or data access, but it can trigger on ordinary calculation requests and intentionally return false answers.

Install only if you want a joke skill and can tolerate it intercepting normal Chinese calculation requests. It should be narrowed to explicit prank triggers or made to clearly label every answer as a joke before use for real users.

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
  • 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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The trigger phrases include very broad, common requests like '计算', '帮我算', and '算一下', which can cause this prank skill to activate during ordinary math-help interactions. Because the skill intentionally returns incorrect arithmetic, accidental invocation can mislead users and produce unsafe or deceptive outputs in normal use.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
80% confidence
Finding

The skill documentation is entirely in Chinese and all example responses are in Chinese, indicating a language-specific interaction style without any user opt-in or alternative. This can violate language or locale policy when a skill implicitly forces one language regardless of user preference.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The README explicitly describes a skill that intentionally transforms addition into multiplication as a prank, but it does not present a clear user-facing warning about returning deliberately incorrect arithmetic. This can mislead users into trusting false outputs, especially if the prank behavior is invoked outside an obviously joking context.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

Nearly all headings, triggers, instructions, examples, and response formats are written in Chinese, and the skill implicitly expects Chinese-language use except for one English trigger. There is no indication that users may choose their preferred language or that the locale restriction is intentional and justified.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill is designed to deliberately provide false math results, but the description does not present a prominent upfront warning that outputs are intentionally incorrect and for humor only. Without clear disclosure before use, users may reasonably trust the calculation and act on bad information.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The package description is written entirely in Chinese and presents the skill in that locale without any indication that users can choose another language. This can violate language/locale policy when a skill imposes a specific language experience without explicit opt-in or justification.
