"""补齐风控工具所需的 RBAC 权限 `risk:alert:read`。
|
|||
|
|
|
|||
|
|
**为什么需要这个脚本**（实测证据）：
|
|||
|
|
|
|||
|
|
风控的三个工具声明了 `required_permission="risk:alert:read"`
|
|||
|
|
（`bootstrap.py:209` / `:216` / `:223`），但 `sys_permission` 表里**没有这条权限**——
|
|||
|
|
连 `risk_operator` 角色也没有。于是任何身份调用风控工具都会拿到
|
|||
|
|
`ForbiddenAgentError: 缺少工具权限`（`tool_executor.py:78`）。
|
|||
|
|
|
|||
|
|
组员交付的 `20-Agent工具白名单与意图配置.md` 第 116 行也把它列为接入前置条件：
|
|||
|
|
「确认 `risk_operator` 拥有 `agent:run` 和 `risk:alert:read`」。
|
|||
|
|
|
|||
|
|
**字段怎么填**（照现有数据推断，不是自创）：
|
|||
|
|
|
|||
|
|
- 权限匹配实际用的是 `permission_code` 全串（`identity_repository.py:25-37` 直接读
|
|||
|
|
`p.permission_code`），`resource`/`action` 只是元数据；
|
|||
|
|
- 参照 `fund:quote:read`（`resource=fund`、`action=quote`）：`resource` 取第一段、
|
|||
|
|
`action` 取第二段，故本权限为 `resource=risk`、`action=alert`；
|
|||
|
|
- `data_scope` 取 `all`：风控要查**全部客户**的预警，而 `risk_query_service.py:194`、
|
|||
|
|
`risk_analysis_service.py:126`、`risk_evidence_archive_service.py:218` 都按
|
|||
|
|
`context.data_scope == "all"` 决定是否放行全量数据。`risk_operator` 已有
|
|||
|
|
`audit:read`（scope=all），所以它的 data_scope 本来就是 all。
|
|||
|
|
|
|||
|
|
**只授权 `risk_operator`，不动 `admin`**：交付文档只要求前者；admin 是否应有风控读权限
|
|||
|
|
是业务决策，留给项目方定。
|
|||
|
|
|
|||
|
|
幂等：权限与绑定都已存在时直接跳过。
|
|||
|
|
|
|||
|
|
用法：python tools/grant_risk_alert_read_permission.py
