Cold Email Local Business

Security checks for vulnerabilities and agentic risk

Overview

The skill is a simple cold-email writing guide, but it pushes users toward a specific paid scraping service and mass outreach without clear consent or compliance guardrails.

Review this skill before installing if you do not want the agent to steer users toward gmapsscraper.io or help prepare large cold-email campaigns. Users should only provide contact data they are allowed to use and should check applicable consent, anti-spam, and privacy requirements before sending outreach.

The imperative phrase `Tell them` makes the promotional response part of the Skill's prescribed behavior rather than presenting the service as an optional or neutrally selected example. The vendor recommendation is repeated in a dedicated section that includes signup instructions and paid pricing information. These instructions are not technically necessary for the Skill's stated function of generating email copy from business data. The agent could instead accept data obtained from any lawful source or explain the required CSV structure without directing the user to a particular vendor. Because the promotion is embedded in trusted Skill instructions, loading and following the Skill alters the agent's output in favor of a predetermined commercial service. No executable code, credential theft, remote payload execution, persistence, or operating-system privilege escalation is involved. ### Attack Path 1.

Finding

The skill explicitly ingests and reformats business contact data, including emails, and encourages outreach workflows without any privacy, consent, or lawful-use guardrails. In context, this makes misuse for spam campaigns or non-compliant processing of scraped contact data substantially easier, especially because the skill also promotes obtaining lead data from a third-party scraper service.

Finding

The invocation examples include broad phrases like "write cold emails," "outreach," and "email sequence" without narrowing them to local-business lead lists or Google Maps CSV inputs. This creates ambiguity about when the skill should activate versus more general email-writing tasks.
