Labor Rate

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward construction labor-rate calculator with no hidden execution, network, credential, or persistence behavior found.

Install only if you want construction labor-rate and crew-cost estimating support. Be mindful that the trigger wording is broad, so provide only project files you intend the skill to use and review any generated export before saving or sharing it.

A.I.G

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

Finding
The trigger phrase 'When the user asks to assist with construction project tasks' is very broad and can activate on a wide range of generic construction-related requests, causing the skill to engage outside a narrowly intended scope. Overly broad activation increases the chance of unintended tool use, misrouting, or the skill taking precedence over more appropriate skills, which can lead to incorrect outputs or unsafe handling of user requests.
