Security checks for vulnerabilities and agentic risk

Overview

ClawScan labels this skill suspicious because a scanner flagged a possible instruction-scope concern; no malicious behavior was reported, but review evidence is incomplete.

Consider the instruction-scope flag and the incomplete scan before installing. Skillspector inspected all four bundled Markdown files, but unresolved references left its analysis partial; the available results do 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

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.
