Agent Harness Construction

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for designing agent tools and recovery patterns, with no executable behavior or hidden data access.

Installers should expect general agent-design advice. If you want tighter activation, ask the publisher to add clearer trigger examples and non-use examples, but no artifact-backed malicious or high-impact behavior was found.

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 invocation guidance says to use the skill when improving how an agent plans, calls tools, recovers from errors, and converges on completion, which describes a very wide class of agent work. It does not provide specific trigger phrases, scope constraints, or exclusion examples, so the skill could be invoked in many ordinary agent-optimization contexts unintentionally.
