Social Post Calendar Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a simple social post calendar guidance skill with no executable code; its activation wording is somewhat broad but not a security concern.

Installers should treat this as a lightweight template skill. Users should avoid pasting private campaign data, customer PII, credentials, or unpublished sensitive business information unless they are comfortable sharing it with their agent workflow.

  • 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 phrases 'structured guidance in the "Social & Marketing" area' and 'repeatable prompts the agent can follow' do not clearly distinguish when this specific skill should activate versus other marketing-related skills. The file also lacks exclusion conditions or negative examples to narrow invocation scope, increasing the chance of unintended activation.
