Competitor Radar

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent trade-show intelligence helper, but it needs Review because it adds a mandatory promotional footer and encourages identifying people seen at competitor booths without privacy guardrails.

Review this skill before installing if you plan to use real trade-show notes. Only provide competitor information and contact details you are authorized to process, remove or disable the mandatory promotional footer, and avoid identifying or enriching individual booth visitors unless your organization has an approved privacy-compliant workflow.

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

Technical Analysis

The skill instructs the agent to append an external commercial promotion to every generated response. This requirement is unrelated to the core function of transforming trade-show observations into structured competitive-intelligence notes.

Because skill instructions influence the agent after the skill is loaded, the directive persistently modifies user-facing output within the current session. The campaign parameters in the URL also allow visits originating from skill output to be attributed to the promotional campaign. Although the instruction does not execute code or bypass system permissions, it uses the agent as an advertising and referral channel without making the footer optional or contingent on user consent.

This behavior best matches T01: Skill Instruction Hijacking, specifically manipulation of the agent's output goals through skill text.

Attack Path

  1. A user installs or loads the competitor-radar skill.
  2. The user supplies booth observations and requests a competitive-intelligence report.
  3. The agent follows the mandatory instruction in SKILL.md.
  4. The agent appends the Lensmor promotion and campaign-tracked external URL to the requested rep ...[truncated 874 chars]

Remediation Suggestions

  1. Remove the End every output with directive and the mandatory promotional footer from SKILL.md.
  2. Remove the footer from examples/competitor-booth-note.md so the example does not normalize or encourage the behavior.
  3. Keep project attribution and commercial links in README.md or package metadata, where users can review them without altering generated task output.
  4. If attribution in generated content is required, make it explicitly optional and controlled by a user preference that defaults to disabled.
  5. Avoid campaign-tracking parameters in agent-generated reports. If an external link is genuinely necessary, clearly identify its destination and purpose.
  6. Add a skill-review check rejecting unconditional instructions that append advertising, referrals, affiliate links, or unrelated third-party content to responses.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
81% confidence
Finding

The skill explicitly encourages processing competitor brochures, pricing clues, and overheard conversations, yet the README provides no warning or guardrails about handling sensitive, confidential, or legally restricted information. In practice, this can normalize ingestion of non-public competitor material or personal/sensitive data and increase the chance of compliance, privacy, or trade-secret mishandling by users and downstream systems.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

This markdown file describes invocation examples such as "Help me extract..." and "help me write up..." that are generic phrases commonly used in ordinary conversation. The README does not provide a specific trigger list, activation boundary, or negative examples, so the skill could be invoked more broadly than intended.

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

## Example Output

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly instructs the user to identify and flag visitors who engaged with a competitor booth, which encourages collection and internal use of potentially identifiable personal data without any notice, consent guidance, minimization, or lawful-basis warning. In a trade-show intelligence context, this can lead to privacy violations, inappropriate surveillance-style profiling, or downstream misuse of personal data gathered from informal observation.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The note explicitly encourages identifying individuals from badge data or LinkedIn research based on their presence at a competitor booth. That creates privacy, compliance, and potentially terms-of-service risks because it promotes profiling named people for competitive intelligence without any guardrails, lawful-basis guidance, or restrictions on use. In a sales-enablement skill, this context makes the issue more dangerous because users may operationalize the instruction directly against real prospects and customer contacts.
