Remediation Suggestions
- Remove the instruction that prohibits specific, relevant recommendations from the audit.
- Remove the mandatory Stripe checkout URL and commercial closing block from the required report template.
- Ensure the core audit produces complete findings based on user-provided information without intentionally withholding actionable results.
- If commercial offerings are retained, clearly label them as optional advertising and separate them from the audit findings.
- Display promotional material only after explicit user consent or a direct request for paid services.
- Do not instruct the agent to manufacture demand by emphasizing pain or making the report intentionally incomplete.
- Allow users to complete the audit without interacting with external payment services.
- Validate outbound links through an approved-domain policy and disclose the destination, merchant, price, and external nature of the transaction.
- Replace “Produce this exact report” with a neutral schema that permits the agent to omit promotional content when it is irrelevant to the user's request.
- Add a policy statement requiring transparent disclosure of commercial affiliation and prohibiting deceptive recommendation suppression.
