Security checks for vulnerabilities and agentic risk

Overview

This skill is only a writing prompt, but it pushes broad Reddit replies toward first-person product endorsements that could be misleading unless the user is truly Tal and discloses the relationship.

Install only if you are Tal or are explicitly authorized to draft truthful Tal-style promotional Reddit content. Before using it, confirm the product relationship and add clear disclosure; do not use generated first-person experience, ownership, or endorsement claims unless they are true.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The trigger conditions are broad enough to auto-apply this skill to many generic Reddit-writing requests, including ordinary replies where the user did not explicitly ask for persona imitation or product promotion. That increases the chance the agent will steer neutral assistance into covert promotional or impersonation-style content without clear user consent.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The skill requires writing in a specific personal voice and instructs the model to present advice as first-person lived experience, which can fabricate identity and experience if the assistant is not actually Tal. In context, the skill also pushes a subtle product mention, making the output resemble undisclosed astroturfing or deceptive endorsement rather than transparent assistance.
