Security audit

Tweet Humanizer

Security checks for vulnerabilities and agentic risk

Overview

This is a text-only tweet editing skill with no executable payload, but its metadata is inconsistent about network access and Ollama use.

Reasonable to install for manual tweet editing, but review the metadata first: it should ideally have one authoritative front matter block and should not request general outbound network access unless the Ollama/local model behavior is clearly documented and scoped.

Vulnerability Patterns
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
  • 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

Finding

The commented documentation states that Sara owns the insight-to-social and blog-to-social pipelines and that tweet-humanizer is not a pipeline step. This conflicts with the active manifest description, which presents the skill as a post-draft QA pass to use after another agent drafts tweet content.
