Security checks for vulnerabilities and agentic risk

Overview

The skill is a documentation-style helper for reviewing Cloud Agent build migration and does not show hidden execution, credential use, or destructive behavior.

This appears safe to install as guidance for Cloud Agent build migration, but users should be aware that the referenced workflow file is missing from the package, so the skill may be incomplete or less useful until that reference is supplied.

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 enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

- Keep Dockerfiles and install scripts deterministic, non-interactive, and narrowly scoped.
- Do not weaken network, certificate, or package-integrity controls merely to make setup pass.
- Avoid expensive rebuilds until static checks pass. Trigger a build only when the migrate reference says to. Unrelated questions never do.
- Do not enable builds for the environment and do not ask the user to promote, activate, merge, or save a draft as the primary next step.
