Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| verifier_platform_verifyA | 把外部主模型生成的回答和完整可审计 reasoning 交给独立 verifier_platform 核查。question、answer、reasoning 均为必填。工具会先检索服务端配置的 UOB 本地知识库；webSearch 支持 enabled、maxResults（5 或 10）和可选 query，联网搜索复用服务端 DeepSeek API Key。返回本地知识库命中、联网来源、confidence、verdict、修正答案及 Ed25519 签名。 |
| verifier_platform_verify_signatureA | 只读、离线验签：使用 RFC 8785 JCS 规范化 payload，验证 verifier_platform 的 Ed25519 签名和可选 SHA-256。不会调用模型。 |
| verifier_platform_statusA | 只读：查看 verifier_platform 的脱敏配置、策略、审计状态和签名公钥。不会调用模型。 |
