Geo Fact Checker

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward fact-checking helper that uses web research and optional claim extraction to verify and improve factual content.

Install this if you want an agent to fact-check factual drafts using web evidence. Be aware it may trigger on many content-review tasks with factual claims and may suggest rewritten wording; review citations and corrections before applying them to important legal, medical, financial, or public-facing content.

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

Finding

This markdown file says to use the skill "aggressively whenever" the user mentions broad terms like fact-checking, verifying, or validating, and further says to prefer triggering it whenever there is any non-trivial factual content. Those conditions overlap with many ordinary writing and research requests, making the activation scope ambiguous and likely to cause unintended invocation.

Missing User Warnings

Finding

The module docstring states that the surrounding skill may 'apply corrections in the user's content,' which is a user-data-affecting action. In this file there is no confirmation flow, warning comment, or user-facing disclosure tied to that behavior, so the code documentation understates a potentially modifying operation.
