Social Media Calendar

Security checks for vulnerabilities and agentic risk

Overview

This is a non-executable social media planning skill with one documentation error in an example, not evidence of harmful behavior.

Before installing, note that the skill is a planning aid and may ask for business and social performance details; only provide data you are comfortable sharing, verify current platform requirements before use, and keep human approval before scheduling or publishing posts.

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 table row for the Example 1 calendar is interrupted by a second YAML-style header fragment ('name', 'version', 'description'), which is unrelated to the example and contradicts the apparent intent of presenting a clean content-calendar example. This is documentation-level divergence rather than runtime behavior, but it is an active contradiction in the file's stated example content.
