Security audit

Phy Agent Manager

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed planning helper for selecting subagents; it does not include code, persistence, credential handling, or hidden data access.

Install this only if you want a skill that can steer Codex into a subagent-planning workflow. Review the proposed plan before approving execution, especially when it suggests multiple agents or security-sensitive work.

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

Vague Triggers

Finding

The activation rule is ambiguous because it mixes exact commands with subjective heuristics about task complexity, leaving unclear when the skill should engage. In a coordination skill, ambiguous invocation is more dangerous than in a passive reference skill because it can redirect control flow, propose agent execution, and potentially initiate subagent usage the user did not clearly request.
