Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this skill benign with high confidence; scanners found no AIG issues, while Skillspector flagged an account-credit request and external API calls that the verdict considers consistent with the stated search purpose.

The scan was complete for the two listed components. Before installing, consider that the skill makes requests to Superagnt and uses an API key; review whether you trust that service and are comfortable sharing search queries and the key with it. The benign verdict indicates the scanners found the reported behavior coherent with the purpose, not that use is risk-free.

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

The supplied chunk only calls an account-credits endpoint; it performs no search, page parsing, similarity lookup, or Q&A. Although checking credits could support a broader workflow, no such workflow is present in this chunk, whose sole operation is an undeclared account-information query.
