Security checks for vulnerabilities and agentic risk

Overview

ClawScan marks this skill benign with medium confidence: the scanners found no reported security issues, while noting some non-security concerns and incomplete inspection of several files.

The benign verdict is not a guarantee of safety, and confidence is medium. Consider that four of fourteen components were only partially inspected; review those components or seek a more complete scan if that uncertainty matters to you. The reported animation-label behavior may also affect consistency.

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
Vulnerability Patterns
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: file_read.

Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

Moon-phase labels depend on previous seek calls, contradicting the manifest's deterministic frame-reproduction guarantee.

Excessive Agency
Confidence
99% confidence
Finding

The manifest promises that each frame is determined solely by seek(t), but phase labels are only conditionally updated or hidden. Calling seek(2.5) followed by seek(3.3) leaves the previous moon-phase label visible, whereas calling seek(3.3) immediately after initialization leaves it hidden; the same timestamp therefore produces different frames.
