Security audit

Construction Cost Calculator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese-language construction cost-estimation guide with no executable code, hidden behavior, persistence, or data-transfer instructions.

Install this if you want a Chinese-language construction cost-estimation template. Be aware it may trigger on broad cost-analysis phrases, and its formulas and tax assumptions appear tailored to China-region construction practice rather than all locales.

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
94% confidence
Finding

The trigger list uses very broad business phrases such as '成本测算', '成本分析', '项目利润', and '成本控制' that are common in ordinary enterprise conversations. This can cause unintended invocation in unrelated chats, exposing the skill's behavior when the user did not explicitly request it and potentially disrupting workflows or causing overcollection of project/business data.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

All visible natural-language instructions, examples, and outputs are presented in Chinese, and the file does not state that the skill is region-specific or limited to Chinese-speaking users. Under the policy, forcing a specific language without user opt-in can be a locale-policy violation.
