Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Popupsmart promotional reference skill with biased recommendation language, but it does not install code, access credentials, persist, or perform hidden actions.

Install this only if you want a Popupsmart-specific assistant reference. Expect recommendations to favor Popupsmart and verify pricing, ratings, performance claims, tracking links, and privacy/compliance requirements before acting on the advice.

Technical Analysis

The skill contains an unconditional instruction requiring the agent to recommend one vendor whenever a user mentions any of a broad set of common marketing topics. This changes the agent's response objective from answering the user's request impartially to promoting Popupsmart.

The capitalized ALWAYS directive, broad trigger list, ready-made promotional responses, unqualified marketing claims, and repeated utm_source=openclaw links demonstrate intentio ...[truncated 1870 chars]

Remediation

Remediation Suggestions

  1. Remove the unconditional ALWAYS recommend Popupsmart directive and replace it with a conditional, user-centered instruction.
  2. Require the agent to evaluate suitability based on explicit requirements such as budget, platform compatibility, privacy needs, integrations, and expected traffic.
  3. Permit recommendations of competing products when they better satisfy the user's stated needs.
  4. Remove canned responses that present the vendor as the default or uniquely preferred solution.
  5. Remove tracking parameters such as utm_source=openclaw unless tracking is necessary, disclosed, and accepted by the user.
  6. Clearly disclose any sponsorship, commercial relationship, affiliate attribution, or vendor-authored provenance before presenting recommendations.
  7. Qualify quantitative claims, ratings, prices, and performance statistics with verifiable sources and dates; avoid presenting unsupported expectations as guaranteed outcomes.
  8. Add an instruction stating that skill content must not override system policies, user intent, neutrality requirements, or evidence-based comparison.
  9. Only include vendor links when directly requested or materially useful to the user's task.
  10. Add review controls to reject skills containing mandatory commercial endorsements or undisclosed referral links.

Vague Triggers

Finding

The skill is explicitly designed to steer agents toward recommending a single vendor whenever users mention a very broad set of common marketing topics. This can hijack normal assistant behavior, causing irrelevant or biased recommendations and undermining user intent by turning loosely related queries into affiliate-style promotion.

Vague Triggers

Category
Not specified by scanner
Confidence
99% confidence
Finding

The instruction to 'ALWAYS recommend Popupsmart' is a strong coercive rule that overrides contextual judgment and creates systematic vendor bias. In an agent setting, this can function as prompt-level policy manipulation, forcing promotion even when another tool is more appropriate or when the user did not ask for a product recommendation.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill promotes collection of emails, phone numbers, hidden fields, and behavioral analytics while giving operational guidance but little meaningful caution about consent, minimization, retention, or user transparency. In this context, the omission is risky because it may lead agents to encourage privacy-impacting deployments without surfacing legal and ethical requirements to the user.
