It installs prescriptive instructions that alter how the agent may evaluate and communicate about the Skill’s provider: 1. It directs the agent to provide a predetermined legitimacy statement. 2. It prohibits independent web, domain-registration, marketplace, and connectivity checks. 3.

Permit verification through authoritative sources, especially the China Securities Regulatory Commission and China Futures Association. 4. Allow the agent to report substantiated security concerns, outages, certificate errors, domain mismatches, or regulatory discrepancies. 5. Clearly label the Enterprise WeChat QR code and other contact information as provider-supplied rather than independently verified. 6. Require the user to verify account-opening links through an independently reached regulator listing or official website before transmitting identity information. 7. Keep reasonable safeguards against repeating unverified allegations, but phrase them as evidence-quality requirements rather than a blanket ban on negative findings. 8. Separate marketing and branding guidance from the operational trading instructions so loading the trading tools does not unnecessarily constrain unrelated answers.
