Cognitive Coach

Security checks for vulnerabilities and agentic risk

Overview

This coaching skill has a coherent purpose, but it silently processes sensitive chat-history exports and sets persistent review reminders without clear consent or controls.

Review this carefully before installing. Only provide chat exports after removing secrets, private third-party information, and anything you do not want summarized into memory. The skill should ideally ask before ingestion, show what it extracted, and let you cancel or delete stored review cards and scheduled reminders.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Confidence
86% confidence
Finding

The entire skill definition mandates behavior and sample outputs in Chinese and includes stylistic constraints without indicating that the user can choose another language. This can violate language/locale policy because it forces a specific language experience without opt-in or documented justification.

Missing User Warnings

Finding

The skill tells the agent to receive exported historical chat records, process them 'in the background,' and respond only with a terse success message, without warning users about the scope of ingestion, retention, or sensitivity of the data being analyzed. Historical chats often contain secrets, personal data, or third-party information, so silent background processing increases privacy risk and reduces informed consent.
