## 6. Resources
|
||||
|
||||
```python
|
||||
class SkillResource(BaseModel):
|
||||
skill_name: str
|
||||
display_name: str | None = None
|
||||
description: str | None = None
|
||||
|
||||
class AgentResources(BaseModel):
|
||||
models: list[ModelResource] = []
|
||||
tools: list[ToolResource] = []
|
||||
knowledge_bases: list[KnowledgeBaseResource] = []
|
||||
skills: list[SkillResource] = []
|
||||
files: list[FileResource] = []
|
||||
storage: StorageResource = StorageResource()
|
||||
platform_capabilities: dict[str, Any] = {}
|
||||
```
|
||||
|
||||
`skills` 只包含本次 run 中 pipeline-visible 的 skill facts,例如 `skill_name`、`display_name` 和 `description`。Host 不把这些 facts 追加到 system prompt,也不把它们编排进工具描述;runner 可以自行决定是否放入 model prompt、转换成 MCP surface,或只在自己的策略层使用。
|
||||
|
||||
资源列表是本次 run 的授权结果。History / Event / Artifact 访问通过 permissions、`ctx.context.available_apis` 和 Host 侧 run session 校验控制,不作为可枚举 resource list 暴露。Runner 只能通过 `AgentRunAPIProxy` 访问这些能力。
