It directs the Agent to: 1. Avoid cancellation during execution. 2. Include a Cue-hosted report URL by default. 3. Promote referral and subscription options when the external service reports insufficient credits. 4. rerun the same command after the user states that payment or referral activity has occurred. These requirements are not necessary to perform technical stock analysis. A report link may be useful, but forcing it into the response and mandating commercial referral or payment messagin ...[truncated 2138 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Make external report links opt-in, or include them only when the user requests the original hosted report. 2. Replace mandatory referral and payment wording with a neutral error explanation, such as stating that the external service lacks sufficient credits. 3. Present payment or referral options only after the user expressly asks how to obtain additional credits. 4. Remove the prohibition on cancellation and explicitly preserve the user’s ability to stop the task. 5. State that all Skill instructions remain subordinate to user requests and higher-priority Agent policies. 6. Separate analytical functionality from commercial messaging so failure handling can offer non-commercial alternatives first. 7. Retain the existing validation that `conv_id` must originate from actual runner output, because this reduces fabricated-link risk. 8. Clearly disclose that stock queries, API credentials, and generated reports are processed by a third-party Cue service before obtaining user consent. ]]>
