Co Op Mission Planner

Security checks for vulnerabilities and agentic risk

Overview

This skill is a text-only collaboration planning guide with no hidden external actions, persistence, or privileged behavior.

Reasonable to install if you want a lightweight text guide for shared task planning. It will surface a localized alternate name and can return its own template text, but inspection found no external actions, data access, or persistence.

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 declared description presents a domain-specific coordination assistant for shared tasks. However, the code does not contain logic tailored to assigning roles, planning handoffs, aligning collaborators, or producing low-conflict coordination language. Instead, it loads SKILL.md, extracts metadata and markdown sections, and formats them into a guidance card. It also supports modes that reveal metadata or the raw template itself. While this may support a skill system internally, the actual implemented behavior is materially different from the declared end-user purpose, so this is a mismatch.

Finding

The file includes a natural-language locale marker, 'Chinese name: 合作任务规划', but does not clarify whether language presentation is optional or user-selected. Under the policy rule, forced or implied locale constraints without opt-in can be a natural-language policy concern.
