 `DEEPSEEK_BASE_URL` and `DEEPSEEK_API_KEY`, so callers can use real model

 `provider` selects a provider route registered by the chosen Cordis composition; `model` is the model id resolved by that adapter. `max_tokens` is an optional positive per-request output-token cap for the root agent and its in-process descendants; omission leaves the provider default in control. Compaction summaries keep the separate limit configured by their compaction plugin. The bundled default composition registers `deepseek-official`. A custom composition can mount `llm-pi-ai`, configure provider-specific credentials/endpoints there, and select any provider/model present in pi-ai's installed catalog.
 
+The [minimal-agent tutorial](../../docs/user/guide/python-sdk-minimal.md) provides a complete standalone Cordis file and runnable SDK example for using the two-tool minimal mode without the Web UI.

 `Session.run()` owns an activity interval from its prompt's durable inbox receipt through the next whole-agent idle and returns `RunResult(session_id, final_response, events, notifications, session_root)`. The result has no prompt-level status or turn reason: `final_response` is the last committed root-session assistant text in the interval, not an output causally assigned to the prompt. Steering, injected context, and other queued work may contribute before idle.
 
 `HarnessClient` retains discovered subagent ancestry for the lifetime of the runtime process. During each `Session.run()`, `RunResult.notifications` and `on_notification` receive the root session and all known descendant notifications in wire order, including nested subagent lifecycle and session events. `RunResult.events` contains root-session events only, so descendant messages cannot replace the root response. The low-level `session_prompt()` returns the queued `MessageId` immediately; callers that bypass `Session.run()` own any later activity boundary themselves.

 `provider` 用于选择当前 Cordis 组合已注册的提供方路由；`model` 是该适配器解析的模型 ID。`max_tokens` 是可选的正整数，用于限制根 agent（智能体）及其进程内后代每次请求的输出 token；省略时由提供方默认值控制。压缩摘要继续使用压缩插件单独配置的上限。内置默认组合注册 `deepseek-official`。自定义组合可以挂载 `llm-pi-ai`，在其中配置各提供方的凭据与端点，再选择 pi-ai 已安装目录中的任意提供方/模型组合。

 `Session.run()` 拥有一个从提示词进入持久 inbox 时开始、到整个 agent 下一次进入空闲状态为止的活动区间，并返回 `RunResult(session_id, final_response, events, notifications, session_root)`。结果不携带提示词级状态或轮次原因：`final_response` 是该区间内根会话最后提交的助手文本，并非因果上归属于该提示词的输出。steering（中途引导）、注入的上下文和其他排队工作都可能在进入空闲状态前参与其中。
 
 `HarnessClient` 会在运行时进程的生命周期内保留已发现的 subagent（子 agent）祖先关系。每次执行 `Session.run()` 时，`RunResult.notifications` 与 `on_notification` 会按协议传输顺序收到根会话及所有已知后代的通知，其中包括嵌套 subagent 的生命周期事件与会话事件。`RunResult.events` 只包含根会话事件，因此后代消息不会覆盖根会话回复。底层 `session_prompt()` 会立即返回已排队消息的 `MessageId`；绕过 `Session.run()` 的调用方必须自行负责后续的活动边界。
