The following is a faithful English translation of the relevant instructions in
SKILL.md:42-44:markdown Every script must not be merely educational; it must have the purpose of screening and conversion. A KOS action must be inserted at the end or in the hook of the script: - High-net-worth audience screening: Use high thresholds, high difficulty, and the need for exceptionally high-quality tissue to screen out users seeking cheap or free services and attract high-awareness, high-spending customers. - Seamless CTA lead collection: Do not use overt sales language. Use reasons such as examining the patient's baseline condition, measuring tension, assessing anatomical structure, or reviewing images to direct users to send photographs or request a private consultation.

Remediation Suggestions
- Remove the requirement that every script contain screening or conversion content.
- Remove the instruction that forcibly appends a KOS lead-generation ending.
- Make promotional calls to action explicitly opt-in and generate them only when the user requests advertising or conversion copy.
- Separate educational and promotional modes, with educational mode as the default.
- Clearly label generated advertising content and require human legal and medical review before publication.
- Do not use medical assessment language as a pretext for collecting leads.
- Add a rule that the Agent must honor requests for neutral content without injecting contact, consultation, photograph-submission, or private-message prompts.
