Caveman Help

Security checks for vulnerabilities and agentic risk

Overview

This is a simple help-card skill that displays caveman-mode reference text and does not install code, persist changes, or access data.

Before installing, note that ordinary phrases like "caveman help" or "normal mode" may interact with caveman-mode behavior. This is a usability concern, not evidence of unsafe access or hidden behavior.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
92% confidence
Finding

The skill advertises broad natural-language triggers such as "caveman help" and "what caveman commands," which can be matched during ordinary conversation rather than explicit invocation. That increases the chance of unintended activation, causing the agent to switch behavior and emit skill content when the user did not actually intend to invoke the reference card.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The deactivation phrases "stop caveman" and especially "normal mode" are generic enough to appear in unrelated dialogue, quoted text, or instructions about other systems. This can unintentionally disable the mode, creating reliability and control issues and making the skill susceptible to prompt-injection-style interference through casual language.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

The instruction "Output in caveman style" imposes a specific language/style transformation by default rather than explicitly offering it as an opt-in at response time. This can conflict with language or locale policy expectations when a user requests help content but does not affirmatively choose that style in the current interaction.
