taskflow

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only workflow orchestration skill whose durable task behavior is disclosed and aligned with its purpose.

Install this if you want agents or plugins to coordinate durable multi-step workflows. Be aware that workflows built with it may persist small state and launch linked child tasks, so callers should keep stored state minimal and avoid placing sensitive content in stateJson or waitJson unless needed.

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

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
