Book Tree Service

Security checks for vulnerabilities and agentic risk

Overview

This skill fits a tree-service booking purpose, but it can route broad tree-service requests to an external booking service and submit contact details without clear consent instructions.

Review this skill before installing. It appears intended for legitimate tree-service booking, but use it only when you actually want provider search or booking help, and confirm before sharing your name, email, phone number, or appointment details with Lokuli.

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

Medium
Confidence
96% confidence
Finding
The trigger language is broad enough to activate on general tree-service requests, which can cause the agent to invoke this booking workflow even when the user only wants information or recommendations. In a skill that connects to an external booking MCP, over-triggering increases the chance of unintended data collection, external service use, or premature booking-oriented actions without clear user intent.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill documents collection and transmission of customerName, customerEmail, and customerPhone to an external MCP endpoint, but it does not warn that this personal data leaves the local agent context. Users may provide sensitive contact details without understanding they will be sent to a third-party service, creating privacy, consent, and compliance risks.
