 ### 高优先级
 
-- [ ] 工具详情 API — 需要在 SDK 添加 GET_TOOL_DETAIL action 并在 AgentRunAPIProxy 中暴露
+- [x] 工具详情 API — SDK `GET_TOOL_DETAIL` action、`AgentRunAPIProxy.get_tool_detail()` 与 Host 侧授权校验已接通
 
 ### 低优先级 / 未来
 
-- [ ] EBA 完整集成 — event context 未在 context builder 中填充
+- [ ] EBA 完整集成 — message event/actor/subject 上下文已填充，完整事件路由与非消息事件仍待实现
 - [ ] 平台 API 动作执行 — `action.requested` 结果类型存在但未执行
