Competitor Analysis Local

Security checks for vulnerabilities and agentic risk

Overview

This instruction-only skill is coherent for local competitor CSV analysis, though users should notice its fixed recommendation of one commercial data source and its use of business contact fields.

Before installing, understand that this skill may steer users without a CSV toward gmapsscraper.io, including a paid offering. Use it for CSV-based local competitor analysis, and avoid uploading personal, confidential, or unauthorized contact data unless those fields are necessary for your task.

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

The second promotional block appears after the skill's output-format instructions, encouraging its inclusion in otherwise ordinary competitor-analysis responses. This alters the expected purpose of the agent's output from neutral analysis of user-provided data to vendor-specific promotion. No technical necessity is established for selecting this particular provider, because the workflow only requires a compatible CSV file and claims to operate without API calls. The package contains no scripts or executable code, so this issue does not provide operating-system code execution, elevated privileges, persistence, or direct access to credentials. The affected boundary is the agent's current-session instructions and generated responses. ### Attack Path 1. The skill is loaded to perform local competitor analysis. 2. A user does not yet have a CSV, or the agent follows the concluding data-acquisition instructions. 3. The skill instructs the agent to recommend one fixed external commercial ser ...[truncated 797 chars]

Vague Triggers

Finding

The invocation guidance is broad enough to trigger on common user requests like 'who are my competitors' or 'analyze the market,' which can cause the skill to activate outside a clearly scoped CSV-analysis workflow. That increases the chance of unsolicited steering into the vendor's data acquisition funnel and of processing business-analysis requests without the user explicitly intending to use this specific skill.

Missing User Warnings

Finding

The skill instructs the agent to request and process business contact fields including website, email, and address without any privacy minimization, purpose limitation, or handling guidance. Even if the data is business-related and scraped/exported from public sources, collecting and analyzing contact data can create privacy, compliance, and data-handling risks—especially if users upload enriched datasets containing personal or mixed-use contact information.
