Home Water Leak First Hour Log

Security checks for vulnerabilities and agentic risk

Overview

This is a document-only home water leak logging skill with clear safety limits and no code, network, credentials, or persistence behavior.

Installers should understand this skill is for organizing and documenting the first hour of a home water leak, not for repairing plumbing or electrical problems. It should be safe to use as a prompt-only checklist, but users should still call emergency help or qualified professionals for flooding, electrical hazards, structural danger, sewage, or unsafe conditions.

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

Confidence
97% confidence
Finding

The checklist explicitly states 'Language is English only,' which is a natural-language locale restriction. The file does not indicate user choice, opt-in, or a clear justification for limiting the skill to English, so this appears to violate the language/locale policy.

Vague Triggers

Finding

This markdown file describes the skill's input and workflow in general terms, but it does not specify precise invocation phrases, scope boundaries, or negative examples for when the skill should not activate. Phrases like 'User provides leak discovery details' could apply to a wide range of ordinary conversation about household leaks, increasing the chance of unintended invocation.

Natural-Language Policy Violations

Confidence

Finding

The manifest sets language: "en", which is a natural-language locale constraint. The file does not indicate that the user can opt into another language or that the English-only setting is required for a documented region-specific purpose.

Natural-Language Policy Violations

Confidence

Finding

The manifest sets the skill language to "en", which is a natural-language locale constraint. Under the policy rule, locale restrictions should either offer user opt-in or be clearly justified as region- or compliance-specific; this file does neither.
