Security audit

Caption Writer

Security checks across malware telemetry and agentic risk

Overview

This is a coherent caption-writing skill with only a minor activation-scope caveat, not evidence of unsafe behavior.

Before installing, be aware that this skill may be selected for broad caption requests and may read local brand-profile.md and voice.md files to match brand voice. It does not appear to post content, install software, use credentials, or run commands.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The trigger phrases are broad enough to match generic writing-help requests such as 'write a caption' or 'what should I write for this post,' which can cause the skill to activate in situations where the user may not specifically intend to use this workflow. Overbroad activation can lead to unintended context loading, incorrect tool routing, or bypass of more specialized skills, especially in systems that auto-select skills from natural language.
