Ai Cost Calculator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward AI cost calculator with disclosed price-checking commands and no evidence of hidden access, persistence, or destructive behavior.

Install this if you are comfortable with Chinese-language instructions and with optional curl commands that contact AI providers' pricing pages. Verify current pricing independently before relying on the static numbers in the skill.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium

Confidence
95% confidence
Finding

The manifest description and the entire skill content are written only in Chinese, with example invocations also exclusively in Chinese. This creates a language/locale constraint for users without any opt-in, alternative language support, or stated regional justification, which matches the policy's language-choice concern.

Confidence

Finding

The manifest description is written entirely in Chinese ('AI成本计算器 - 对比各大模型成本,优化API支出') with no indication that the skill is optional for Chinese-speaking users or limited to a Chinese locale. Under the language/locale policy, this can be a policy issue when a specific language is imposed without user opt-in or documented regional scope.
