Security checks for vulnerabilities and agentic risk

Overview

This is a small GitHub CLI helper skill with broad but disclosed GitHub access and no bundled code, persistence, or hidden behavior.

Install only if you want the agent to use your gh CLI context for GitHub tasks. Review commands before approving any GitHub mutation such as creating issues, merging PRs, cancelling runs, or using gh api with non-GET methods.

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 manifest description says the skill can 'Interact with GitHub using the gh CLI' and lists broad capabilities like issues, PRs, CI runs, and advanced queries, but it does not define any specific activation phrases, scope boundaries, or exclusion conditions. For a manifest file, this can make invocation conditions ambiguous and increase the chance of unintended triggering for general GitHub-related requests.
