China Furniture Sourcing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a static China furniture sourcing reference tool with local lookup code and no evidence of hidden access, persistence, or data exfiltration.

Before installing, treat the sourcing data as reference material rather than verified supplier due diligence, since the package does not include source URLs or live validation. From a security perspective, the inspected skill is limited to local bundled data lookups.

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

MCP Least Privilege
Confidence
86% confidence
Finding
The skill is invocable and references an implementation in `do.py` that performs file reads from `data.json`, but the manifest does not declare any `permissions` or `allowed-tools` scope. Missing explicit tool scoping weakens least-privilege controls and can cause the runtime or reviewers to underestimate what the skill can access, especially if file access later expands beyond the intended dataset.

Natural-Language Policy Violations

Low
Confidence
93% confidence
Finding
This JSON file is a manifest-style file, so SQP-3 applies to its natural-language values. The source field includes Chinese text alongside English, but the file provides no user-facing language selection or explanation that the skill is intentionally China-locale-specific, which can conflict with language/locale policy requirements.

Natural-Language Policy Violations

Low
Confidence
84% confidence
Finding
The module docstring explicitly frames the skill as "China furniture industry intelligence," which imposes a country-specific locale/context in natural-language metadata. There is no nearby language indicating user choice, opt-in, or a documented policy justification for restricting the skill to this locale.
