Security audit

Guest Circuit

Security checks for vulnerabilities and agentic risk

Overview

This skill performs disclosed public podcast-appearance research and writes a local report, with no evidence of hidden execution, credential use, or destructive behavior.

Installers should expect this skill to spend web-search calls, use public web and podcast-index sources, and create a local report file. Provide an anchor fact for the intended guest and avoid using it for sensitive or private outreach plans unless local report persistence is acceptable.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The invocation guidance includes broad natural-language triggers like "research X before outreach," which can overlap with ordinary user requests and cause the skill to run unexpectedly. Because the skill performs multi-source web searches and creates a report, accidental invocation can expand data access and side effects beyond what the user explicitly intended.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill instructs the agent to write a local markdown report file, but the top-level description does not clearly disclose this side effect to the user. Hidden file creation can violate user expectations, create unwanted artifacts, and in some environments may expose sensitive research targets or operational intent through local persistence.
