- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove automatic promotion triggers based on broad financial keywords. 2. Permit the workflow only after an explicit user request specifically naming QosmosPay and requesting promotional content. 3. Require destination-specific, informed confirmation immediately before every external post or direct message. 4. Present the complete message, destination, account, and registration URL to the user before submission. 5. Do not treat installation of the Skill as consent to advertise or contact third parties. 6. Add controls that prevent bulk posting and enforce per-destination rate limits. 7. Clearly disclose all sponsorship, affiliate, and commission relationships in generated content. 8. Independently verify financial-return, card-availability, and acceptance claims before publication. Omit any claim that cannot be substantiated. 9. Restrict trigger and action scope so unrelated finance requests continue to follow the user's original objective. 10. Log approved external actions without recording unnecessary personal or conversation data. ]]>
