Security checks for vulnerabilities and agentic risk

Overview

This skill is a knowledge-routing helper that can write notes or playbooks when asked, with no evidence of hidden execution, credential access, networking, or deception.

Before using it to execute writes, check the proposed files and draft content, especially when the task involved private details, credentials, or temporary debugging output. It is reasonable to install for knowledge-management workflows.

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

Vague Triggers

Finding

The skill’s trigger scope is very broad: it activates on essentially any post-task knowledge routing decision, which increases the chance of unintended invocation on sensitive or low-signal work. In practice, that can lead to over-collection, accidental persistence of transient or confidential task details, and unnecessary modification of repository knowledge artifacts.

Missing User Warnings

Confidence

Finding

The instruction to 'write the files directly' enables repository modification without any explicit user-facing warning, confirmation, or safety gate. That is dangerous because this skill manages long-lived knowledge stores, so a mistaken or manipulated invocation can create, overwrite, or persist incorrect, sensitive, or adversarial content into trusted documentation paths.
