Security audit

technical-writer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a technical-writing helper with documentation templates and examples, and I found no hidden execution, persistence, or data-exfiltration behavior.

Install this only if you want a broad technical-writing assistant. Review generated API examples before publishing, especially headers and request bodies, because documentation examples can accidentally include sensitive sample values if supplied by the user.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest description says 'Use when: technical documentation and writing,' which is a broad activation cue and does not clearly distinguish technical-writing tasks from ordinary writing or editing requests. It also provides no exclusion conditions or negative examples to narrow when the skill should and should not activate.

Content

No source excerpt is available for this finding.

External Transmission

Medium
Category
Data Exfiltration
Confidence
60% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
