Security audit

Caveman

Security checks for vulnerabilities and agentic risk

Overview

This skill only changes response style for terse communication and does not request tools, files, credentials, network access, or system privileges.

Install only if you want terse replies and are comfortable disabling it with "stop caveman" or "normal mode" if it activates after a broad brevity request.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill advertises wenyan/classical Chinese output modes as part of normal operation, but the auto-trigger design does not require explicit user selection of those language variants. This can cause unexpected language switching or non-user-preferred output, reducing comprehensibility and increasing risk when handling instructions, warnings, or technical guidance.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger set is broad enough to activate on ordinary requests like 'be brief' or 'less tokens', which can unintentionally force a persistent response-style change across later turns. Because the mode persists until explicitly disabled, accidental activation can degrade clarity, alter safety-critical messaging, and create confusing behavior without clear user consent.
