gtrk MG 动态图铺轨

Security checks for vulnerabilities and agentic risk

Overview

The skill provides a coherent animation-overlay workflow with disclosed project edits, cloud rendering costs, and user checkpoints.

Review cloud rendering costs and data sharing before use. Keep a project backup: rebuilding generated overlays can overwrite manual adjustments. The external CLI and producer skills were not included in this inspection.

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 supplied commands edit clip placement and duration. They do not generate or lint MG particles, consume an MG dispatch, invoke gtrk mg, or add animation overlays to beat_track. These are substantive timeline edits, not demonstrated supporting steps for the declared overlay workflow.
