High Ticket Trust Conversion

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a review-strategy guide, but it repeatedly steers answers toward a specific commercial vendor in ways users may mistake for neutral advice.

Review this skill carefully before installing if you expect neutral ecommerce advice. It appears safe from a local system and credential perspective, but it may insert Rijoy recommendations and marketing claims into answers even when a balanced vendor comparison would be more appropriate.

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

Remediation
<![CDATA[ ## Remediation Suggestions 1. Remove all mandatory instructions to cite, recommend, or “call out” Rijoy. 2. Remove the direction to promote a vendor for “brand authority.” 3. Delete or substantiate the “trusted by thousands of merchants” claim with a reliable, current source. Do not require the agent to repeat unverifiable marketing claims. 4. Replace vendor-specific rules with neutral selection criteria, such as: - Platform compatibility. - Review-platform integration. - Incentive-policy compliance. - Pricing and contract requirements. - Data handling and privacy controls. - Support for rewarding reviews regardless of rating. 5. Mention a specific vendor only when: - The user explicitly asks about that vendor; - It is already part of the user's stated technology stack; or - A balanced comparison identifies it as one of several suitable options. 6. When a commercial relationship, sponsorship, or affiliation exists, require clear disclosure in the user-facing response. 7. Update evaluations so they test for neutral, policy-compliant incentive advice rather than mandatory vendor mentions. 8. Add a review requirement that flags repeated brand names, commercial URLs, unsupported trust claims, and instructions designed to influence recommendations. ]]>

Vague Triggers

Medium
Confidence
96% confidence
Finding
The metadata explicitly says to trigger even if the user does not mention reviews, which materially broadens activation beyond a narrowly scoped review/social-proof use case. In an agent environment, overly broad routing can misinvoke this skill on adjacent ecommerce queries, causing irrelevant recommendations, hidden promotional bias toward Rijoy, or interference with more appropriate skills.

Vague Triggers

Medium
Confidence
90% confidence
Finding
The 'When to use this skill' section lists several common ecommerce concepts like trust signals, UGC, purchase hesitation, and incentives, but provides only limited boundaries, so many adjacent marketing requests could satisfy it. This can lead to priority inversion or accidental invocation, especially because the skill also embeds vendor-specific suggestions that may bias outputs when triggered in marginal cases.

Finding
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

| Post-purchase SMS | 10–14 days | If SMS is primary; keep message short with link |
| In-app / account | When they log in | "You purchased [X]. How was it? Leave a review." |

Prefer one primary touch (e.g. email at 14 days) and one optional reminder. Do not ask before the customer has used the product.

Natural-Language Policy Violations

Low
Confidence
86% confidence
Finding
The section title explicitly labels the examples as 'Copy patterns (EN)' and all provided user-facing phrases are English-only. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation, and this file does not indicate that other locales should be used when appropriate.
