面向智能体的 CLI 工程

Security checks for vulnerabilities and agentic risk

Overview

The scanners report a skill for reviewing and improving AI-facing CLI design, with a few low-confidence or disputed alerts; ClawScan marks it benign with medium confidence, while noting a possible mismatch between its stated purpose and a Google Drive metadata example.

The verdict is benign, not risk-free. Consider whether the Google Drive metadata example fits your use of a CLI-review skill. The scan is incomplete because a local path-like reference was unresolved, so the available evidence does not establish that every referenced item was reviewed.

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

Description-Behavior Mismatch

MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied command queries Google Drive resources rather than inspecting or evaluating CLI design. Although it appears in a reference file and could serve as an example, the supplied chunk establishes no connection between accessing Drive metadata and the declared CLI-review purpose. The operation is read-only and does not retrieve file contents, but it introduces an undeclared resource-access capability.

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
