Cell-Plan Pruning

Security checks for vulnerabilities and agentic risk

Overview

The skill recommends cancelling cloud storage without checking stored data, replacement capacity, or getting clear approval for account changes.

Use the calculator as advice and approve each account change separately. Before cancelling cloud storage, check actual usage, replacement capacity, backup migration, and the provider’s retention terms. The clean static scan is consistent with the local script, but does not resolve these workflow concerns.

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 workflow recommends removing add-ons, explicitly including cloud storage elsewhere in the skill, without first checking stored data or downgrade consequences. Depending on the provider, cancellation or exceeding a free-tier quota could stop backups, restrict access, or eventually cause data deletion. The instruction to execute pruning makes this omission more consequential than a purely informational price comparison, although no automatic cancellation is shown.
