+# Agent Note: The minimal preset owns the complete RL agent composition
+
+Status: implemented
+
+English | [中文](2026-08-10-minimal-preset-owns-rl-composition.zh.md)
+
+## Problem
+
+The Web surface offered two owners for the Claude SWE-compatible RL agent: a process-wide `core-web.cordis.yml` patch and the per-session `minimal` preset. Once [agent presets](../architecture/2026-08-03-per-session-agent-presets.md) became the agent-composition boundary, the preset's scoped `deployment:persona` shadowed the overlay's corrected global persona with stale coding-agent text. The overlay test mounted no preset, while the preset test booted without the overlay, so neither exercised the composition users selected.
+
+The split also hid other drift. The preset mounted one-shot Bash rather than the [persistent Bash](../feature/2026-07-29-persistent-bash-str-replace-editor.md) used by the RL harness and omitted the RL compaction policy. Keeping both owners makes every future prompt, tool, and policy change a cross-product.
+
+## Decision
+
+The shipped Web `minimal` preset is the sole Web owner of the RL agent composition. It declares an entry-local PTY registry and local backend, persistent `bash` with the RL environment description and 300-second timeout, `str_replace_editor`, and an entry-local compaction backend. Tool presentation remains a deployment choice. The compaction policy keeps the RL threshold, absolute retention, generation cap, and retry count; model capacity comes from routed adapter metadata because `contextWindow` is no longer a compact-basic config field. The editor accepts no `requireAbsolutePath` setting because absolute paths are its unconditional contract.
+
+The preset persona is exactly `You are a helpful software engineer assistant.` and sets `complete: true`. A complete `PromptSection` participates in ordinary assembly so tools, contexts, variables, and cooperative listeners still resolve; after the `system-prompt/assemble` waterfall, the prompt registry restores a detached copy of that section as the sole system-prompt section. Multiple effective complete sections reject assembly. This final registry constraint prevents harness identity, Web orientation, tool guidance, or an assembly listener from appending prompt text.
+
+The process-wide `core-web.cordis.yml` patch is absent. Browser UI, workspace attachment, persistence, filesystem, subprocess, sandbox, permission, model routing, and other cross-session services remain host-owned. Selecting `minimal` changes one agent's model-facing composition without changing other sessions in the Web process.
+
+## Verification
+
+System-prompt and persona package tests prove final complete-section enforcement, including waterfall mutation and duplicate rejection. The shipped-preset composition test asserts the exact prompt, Bash description, absolute editor schema, and two-tool catalog under the default native presentation. The keyless Web replay sends a real request through a `minimal` agent while global identity, Web surface text, and a test section are registered, then executes two persistent Bash calls to prove environment and cwd state survive and executes the editor through an absolute path.
+
+The standalone [`minimal.cordis.yml`](../../../../examples/jsonrpc-agent/minimal.cordis.yml) mirrors the same prompt, tools, timeouts, and compaction policy for the bundled JSON-RPC runtime. Its keyless SDK replay asserts the assembled system prompt and two-tool catalog, executes persistent Bash across calls, and exercises the editor; the Python SDK tutorial provides the runnable entry point.
+
+## Alternatives considered
+
+**Keep `core-web.cordis.yml` as a compatibility patch.** Rejected because a process patch and a session preset are two independent owners for one agent contract; precedence makes either one capable of silently undoing the other.
+
+**Disable every known prompt contributor in the preset.** Rejected because host rows are process-wide and new contributors would reopen the prompt. A final complete-section constraint expresses the negative guarantee at the registry that assembles the prompt.
+
+**Filter sections only with a prepended waterfall listener.** Rejected because another prepended wrapper can run outside it and append after the filter. Enforcement after the complete waterfall has stable final authority.
+
+**Mount PTY services on the Web host.** Rejected because only the minimal agent consumes them. An entry-local `pty` realm gives the services the same lifetime and scope as their sole consumer without publishing a process-global service from a preset.
+
+## Consequences
+
+The RL prompt is fixed rather than environment-overridable. The Web preset and standalone JSON-RPC example state the same contract for their respective launch surfaces. The model sees only persistent `bash` and `str_replace_editor`; shell state is per agent and disappears with that agent. The preset pays for its own PTY and compaction service instances, while other presets pay nothing for them. The local persistent-shell backend requires the supported POSIX terminal substrate, so this preset is not a Windows agent surface.

+# Agent Note: minimal preset 拥有完整的 RL agent 组合
+
+Status: implemented
+
+[English](2026-08-10-minimal-preset-owns-rl-composition.md) | 中文
+
+## 问题
+
+Web surface 同时由两个位置定义与 Claude SWE 兼容的 RL agent（智能体）：进程级 `core-web.cordis.yml` patch，以及逐会话的 `minimal` preset。[agent preset](../architecture/2026-08-03-per-session-agent-presets.md) 成为 agent 组合边界后，preset 中带作用域的 `deployment:persona` 会用陈旧的 coding-agent 文本遮蔽 overlay 修正过的全局 persona。overlay 测试没有挂载 preset，而 preset 测试启动时没有 overlay，因此两者都没有覆盖用户实际选择的组合。
+
+这种拆分还掩盖了其他偏差。preset 挂载了一次性 Bash，而不是 RL harness 使用的[持久 Bash](../feature/2026-07-29-persistent-bash-str-replace-editor.md)，并且遗漏了 RL 压缩（compaction）策略。保留两个所有者，会使今后每次修改提示词、工具或策略时都必须验证二者的交叉组合。
+
+## 决策
+
+随附的 Web `minimal` preset 是 RL agent 组合在 Web 中的唯一所有者。它声明 entry 本地的 PTY 注册表与本地后端、带 RL 环境描述且超时为 300 秒的持久 `bash`、`str_replace_editor`，以及 entry 本地的压缩后端。工具呈现仍由部署选择。压缩策略保留 RL 的阈值、绝对保留量、生成上限和重试次数；模型容量来自经路由选定的适配器元数据，因为 `contextWindow` 已不再是 compact-basic 的配置字段。编辑器不接受 `requireAbsolutePath` 设置，因为要求绝对路径是它的无条件约定。
+
+preset persona 恰好是 `You are a helpful software engineer assistant.`，并设置 `complete: true`。complete `PromptSection` 参与常规组装，因此工具、上下文、变量和协作式监听器仍会解析；`system-prompt/assemble` waterfall（瀑布式事件）结束后，提示词注册表会将该段落的独立副本恢复为唯一的系统提示词段落。存在多个有效 complete 段时，组装会被拒绝。这项最终注册表约束可防止 harness 身份、Web 定位、工具引导或组装监听器追加提示词文本。
+
+进程级 `core-web.cordis.yml` patch 不再存在。浏览器 UI、workspace 附加、持久化、文件系统、子进程、沙箱、权限、模型路由及其他跨会话服务仍由宿主持有。选择 `minimal` 只会改变一个 agent 面向模型的组合，不会改变 Web 进程中的其他会话。
+
+## 验证
+
+系统提示词与 persona 包测试证明了 complete 段的最终约束，包括 waterfall 修改与重复项拒绝。交付 preset 组合测试在默认原生呈现下断言精确的提示词、Bash 描述、要求绝对路径的编辑器 schema 和双工具目录。无密钥 Web 回放通过 `minimal` agent 发送一个真实请求，同时注册全局身份、Web surface 文本和一个测试段落；随后执行两次持久 Bash 调用，证明环境与 cwd 状态能够保留，并通过绝对路径执行编辑器。
+
+独立的 [`minimal.cordis.yml`](../../../../examples/jsonrpc-agent/minimal.cordis.yml) 为内置 JSON-RPC 运行时复现相同的提示词、工具、超时和压缩策略。其无密钥 SDK 回放会断言组装后的系统提示词与双工具目录，跨调用执行持久 Bash，并使用编辑器；Python SDK 教程提供可运行的入口。
+
+## 考虑过的替代方案
+
+**将 `core-web.cordis.yml` 保留为兼容 patch。** 被拒绝，因为进程 patch 与会话 preset 是同一 agent 约定的两个独立所有者；优先级会使任意一方都能静默撤销另一方的配置。
+
+**在 preset 中禁用每个已知的提示词贡献方。** 被拒绝，因为宿主行属于整个进程，新的贡献方也会重新开放提示词。由组装提示词的注册表实施最终 complete 段约束，才能表达这项否定保证。
+
+**仅使用前置 waterfall 监听器筛选段落。** 被拒绝，因为另一个前置包装层可以在该监听器外执行，并在筛选后追加内容。在整个 waterfall 结束后实施约束，才能稳定拥有最终决定权。
+
+**在 Web 宿主上挂载 PTY 服务。** 被拒绝，因为只有 minimal agent 消费这些服务。entry 本地的 `pty` realm 与唯一消费方具有相同的生命周期和作用域，无需由 preset 发布进程级全局服务。
+
+## 后果
+
+RL 提示词固定不变，不能通过环境覆盖。Web preset 与独立 JSON-RPC 示例分别在各自的启动界面声明相同的约定。模型只看到持久 `bash` 与 `str_replace_editor`；shell 状态按 agent 隔离，并随该 agent 一并消失。preset 为自身的 PTY 与压缩服务实例承担开销，其他 preset 无需承担。持久 shell 的本地后端需要受支持的 POSIX 终端基础环境，因此该 preset 不适用于 Windows agent surface。

 Both plugins are included in the Python runtime closure. The persistent Bash closure also includes the PTY service/local backend and the sandbox services required by that backend. Because `node-pty` executes a native `spawn-helper` on macOS, each packaged macOS runtime executable ships with a `-spawn-helper` sibling; Linux uses `forkpty` directly. A pinned `node-pty` patch checks `DSH_NODE_PTY_SPAWN_HELPER` first, so it remains a true override for a current external consumer that supplies a non-sibling helper. When the override is unset, the patch resolves the packaged executable sibling if present and otherwise preserves upstream lookup in ordinary Node runs. The macOS builders fail before publication when the helper is absent or not executable.

+# Agent Note: One editor family in general-purpose presets
+
+Status: implemented
+
+English | [中文](2026-08-10-default-presets-single-editor.zh.md)
+
+## Problem
+
+The `standard`, `code`, and `cordis` presets exposed both the `read`/`write`/`edit` filesystem tools and `str_replace_editor`. The two interfaces overlap for ordinary file inspection and editing, so every request carried an additional tool schema without adding a distinct default capability. The `minimal` preset has a different composition contract: its exact two-tool roster intentionally includes `str_replace_editor` beside persistent `bash`.
+
+## Decision
+
+The `standard`, `code`, and `cordis` preset configurations mount `dsh-tool-fs` and `dsh-tool-fs-search`, but do not mount `dsh-tool-str-replace-editor`. Code Mode therefore omits `str_replace_editor` from both its registry and generated SDK. The `minimal` preset continues to mount `dsh-tool-str-replace-editor`, and deployments or user-authored presets may still mount the plugin explicitly.
+
+This decision narrows the preset roster rather than removing the tool package or its Python runtime support. The earlier [shared-roster decision](../feature/2026-07-31-even-out-shipped-tool-rosters.md) continues to own why surface-neutral tools live in preset composition; this note owns the editor exception.
+
+## Alternatives considered
+
+**Keep both editing interfaces in the general-purpose presets.** Rejected because the overlapping model-visible schemas increase tool choice without supplying a separate default operation.
+
+**Remove `str_replace_editor` from every shipped composition.** Rejected because the `minimal` preset intentionally exposes that schema as one of its two tools, and explicit deployments remain valid consumers of the standalone plugin.
+
+## Consequences
+
+General-purpose agents use `read`, `write`, and `edit` for filesystem mutations, while the minimal agent retains `str_replace_editor`. Preset composition tests pin its absence from the standard roster, the Cordis roster, and the Code Mode SDK, while the minimal assertions continue to pin its presence.

+# Agent Note: 通用 preset 只提供一套编辑工具
+
+Status: implemented
+
+[English](2026-08-10-default-presets-single-editor.md) | 中文
+
+## 问题
+
+`standard`、`code` 和 `cordis` preset 同时提供 `read`/`write`/`edit` 文件系统工具与 `str_replace_editor`。两套接口在常规文件查看和编辑上重叠，导致每次请求都携带额外的工具 schema，却没有增加独立的默认能力。`minimal` preset 具有不同的组合约定：它固定的双工具清单有意在持久 `bash` 之外提供 `str_replace_editor`。
+
+## 决策
+
+`standard`、`code` 和 `cordis` preset 配置挂载 `dsh-tool-fs` 与 `dsh-tool-fs-search`，但不挂载 `dsh-tool-str-replace-editor`。因此 Code Mode 的注册表和生成的 SDK 均不包含 `str_replace_editor`。`minimal` preset 继续挂载 `dsh-tool-str-replace-editor`，部署配置或用户自定义 preset 仍可显式挂载该插件。
+
+此决策收窄 preset 工具清单，不移除工具包及其 Python 运行时支持。较早的[共享清单决策](../feature/2026-07-31-even-out-shipped-tool-rosters.md)继续说明与 surface 无关的工具为何归 preset 组合所有；本记录说明编辑器例外。
+
+## 曾考虑的替代方案
+
+**在通用 preset 中保留两套编辑接口。** 不予采用，因为重叠的模型可见 schema 增加了工具选择，却没有提供不同的默认操作。
+
+**从所有交付组合中移除 `str_replace_editor`。** 不予采用，因为 `minimal` preset 有意将该 schema 作为两个工具之一，显式部署仍是该独立插件的有效消费方。
+
+## 后果
+
+通用 agent 使用 `read`、`write` 和 `edit` 完成文件系统修改，minimal agent 保留 `str_replace_editor`。preset 组合测试固定其不会出现在 standard 清单、Cordis 清单及 Code Mode SDK 中，同时 minimal 断言继续固定其存在。

 New sessions default to the `workspace-write` permission preset.

-`DSH_TOOLS_MODE` selects `native`, `code`, or `both` for the process; another value fails at boot. [`config/core-web.cordis.yml`](../config/core-web.cordis.yml) is an optional RL-compatible `--patch` overlay that pins native mode, renders only `DSH_SYSTEM_PROMPT` or `You are a helpful software engineer assistant.` as the system prompt, disables Workspace instructions and every Web runtime prompt contribution, and exposes only persistent `bash` and `str_replace_editor` while retaining the shipped host, browser, workspace, persistence, and permission composition.
-
-`DSH_SYSTEM_PROMPT` is passed as the system-prompt [`persona`](../../../packages/core/system-prompt/README.md#config): complete `{{…}}` groups use that contract's strict variable interpolation rules and have no literal-brace escape; any set value, including an empty string, is authoritative and an empty value therefore removes the system prompt, while only an unset variable selects the fallback.

Select 极简模式 when creating a Web session; every other prompt section and model-facing plugin remains absent from that agent while the shared browser, workspace, persistence, sandbox, and permission host stays in place.

+# Get started with the Python SDK
+
+English | [中文](python-sdk.zh.md)
+
+This tutorial installs the Python SDK, runs a checked-in Cordis composition without the Web UI, and uses the same API in your own program. It uses the compact [`minimal.cordis.yml`](../../../examples/jsonrpc-agent/minimal.cordis.yml) configuration as a complete example with a fixed system prompt, tool catalog, persistent-shell behavior, and compaction policy.
+
+## Prerequisites
+
+- Python 3.10 or newer
+- Linux x64, Linux arm64, or macOS arm64
+- A DeepSeek-compatible API endpoint and credential
+- An isolated workspace that the agent may modify
+
+## Install the SDK
+
+Choose either the public package or a source build. Both install the `deepseek-harness-sdk` distribution and expose the `deepseek_harness` Python module.
+
+### Install from PyPI
+
+Create a virtual environment and install the SDK with its same-version bundled runtime:
+
+```sh
+python -m venv .venv
+. .venv/bin/activate
+python -m pip install deepseek-harness-sdk
+```
+
+### Build from source
+
+A source build additionally requires Git, Node.js ^22.19 or >= 24, Corepack-enabled pnpm 11, and `uv`. The following commands build the runtime for the current supported host platform, build both wheels, and install them into the active virtual environment:
+
+```sh
+git clone https://github.com/deepseek-ai/deepseek-harness-sdk.git deepseek-harness
+cd deepseek-harness
+python -m pip install uv==0.11.23
+corepack enable
+pnpm install
+
+case "$(uname -s):$(uname -m)" in
+  Linux:x86_64) runtime_platform=linux-x64 ;;
+  Linux:aarch64|Linux:arm64) runtime_platform=linux-arm64 ;;
+  Darwin:arm64) runtime_platform=macos-arm64 ;;
+  *) echo "unsupported platform" >&2; exit 1 ;;
+esac
+
+pnpm exec tsx scripts/build-exe-for-python-sdk.ts --targets="node24-$runtime_platform"
+version="$(node -p "require('./package.json').version")"
+python scripts/build-python-release.py --package sdk --output-dir dist-python
+python scripts/build-python-release.py \
+  --package runtime \
+  --platform "$runtime_platform" \
+  --runtime-exe "dist-exe/dsh-jsonrpc-agent-pkg-$runtime_platform" \
+  --output-dir dist-python
+python -m pip install --find-links dist-python "deepseek-harness-sdk==$version"
+```
+
+The runtime wheel contains the JSON-RPC executable and every plugin used by the complete [`minimal.cordis.yml`](../../../examples/jsonrpc-agent/minimal.cordis.yml), so neither installation path needs Node.js after installation.
+
+## Run the checked-in example
+
+Set the credential in the environment. Set `DEEPSEEK_BASE_URL` as well when the model is served by an OpenAI-compatible proxy rather than the default DeepSeek endpoint.
+
+```sh
+export DEEPSEEK_API_KEY=sk-your-key-here
+# export DEEPSEEK_BASE_URL=http://127.0.0.1:8000/v1
+```
+
+Run one task from the repository checkout:
+
+```sh
+python examples/jsonrpc-agent/minimal.py \
+  --workspace /absolute/path/to/workspace \
+  --session-root /absolute/path/to/sessions \
+  --session-id example-001 \
+  "Inspect the repository and fix the failing tests."
+```
+
+The script prints the final assistant response. The session root receives a JSONL session log containing the assembled model request and every tool call.
+
+## Use the SDK in your own program
+
+The example is a thin wrapper around this SDK call:
+
+```python
+from pathlib import Path
+
+from deepseek_harness import DeepSeekHarness
+
+config = Path("examples/jsonrpc-agent/minimal.cordis.yml").resolve()
+workspace = Path("/absolute/path/to/workspace").resolve()
+sessions = Path("/absolute/path/to/sessions").resolve()
+
+with DeepSeekHarness(
+    provider="deepseek-official",
+    model="deepseek-v4-flash",
+    max_tokens=49_152,
+    cwd=str(workspace),
+    session_root=str(sessions),
+    cordis=str(config),
+) as harness:
+    result = harness.run(
+        "Inspect the repository and fix the failing tests.",
+        session_id="example-001",
+    )
+
+print(result.final_response)
+```
+
+`DeepSeekHarness` starts the bundled JSON-RPC runtime lazily and reuses it until the context manager exits. Reusing the same harness and session id across calls also preserves the session-owned Bash process, including its working directory, exported variables, and shell functions.
+
+## Understand the example configuration
+
+| Surface | Fixed value |
+|---|---|
+| System prompt | `You are a helpful software engineer assistant.` |
+| Model-facing tools | Persistent `bash` and `str_replace_editor` only |
+| Bash timeout | 300 seconds |
+| Editor output limit | 16,000 characters |
+| Compaction | Trigger ratio `0.8`, retain `20,480` tokens, summary cap `8,192` tokens, one retry |
+| Session persistence | Uncompressed JSONL under `DSH_SESSION_ROOT` |
+
+The configuration omits harness identity, workspace prompt text, skills, one-shot Bash, task tools, and every other model-facing plugin. Filesystem policy facts are logged as runtime user context rather than appended to the system prompt. The editor requires absolute paths as an unconditional current contract, so the obsolete `requireAbsolutePath` option is absent.
+
+## Choose workspace and session IDs
+
+`cwd` selects the workspace available to the agent, while `session_root` stores session logs and state. Use a fresh session id for an independent task; reuse an id only when the next call should continue the same conversation and persistent shell state.
+
+The composition uses `danger-full-access`. Run it only inside a disposable checkout or container: Bash and the editor can modify any path allowed to the runtime process. The persistent PTY backend requires a POSIX terminal substrate and is not a Windows agent surface.
+
+For the complete SDK lifecycle and result contract, see the [Python SDK reference](../../../python/sdk/README.md). For Cordis composition syntax, see [Configuration](./config.md).

+# Python SDK 快速上手
+
+[English](python-sdk.md) | 中文
+
+本教程介绍如何安装 Python SDK、在不使用 Web UI 的情况下运行仓库内置 Cordis 组合，以及如何在自己的程序中调用同一套 API。教程使用精简且完整的 [`minimal.cordis.yml`](../../../examples/jsonrpc-agent/minimal.cordis.yml) 作为示例，其中固定了系统提示词、工具目录、持久 shell 行为和压缩（compaction）策略。
+
+## 前置要求
+
+- Python 3.10 或更高版本
+- Linux x64、Linux arm64 或 macOS arm64
+- DeepSeek 兼容的 API 端点与凭据
+- agent 可以修改的隔离 workspace
+
+## 安装 SDK
+
+可以选择安装公开包或从源码构建。两种方式都会安装 `deepseek-harness-sdk` 分发包，并提供 `deepseek_harness` Python 模块。
+
+### 从 PyPI 安装
+
+请创建虚拟环境，并安装 SDK 及其同版本内置运行时：
+
+```sh
+python -m venv .venv
+. .venv/bin/activate
+python -m pip install deepseek-harness-sdk
+```
+
+### 从源码构建
+
+从源码构建还需要 Git、Node.js ^22.19 或 >= 24、通过 Corepack 启用的 pnpm 11，以及 `uv`。以下命令为当前受支持的宿主平台构建运行时和两个 wheel 包，并将它们安装进当前虚拟环境：
+
+```sh
+git clone https://github.com/deepseek-ai/deepseek-harness-sdk.git deepseek-harness
+cd deepseek-harness
+python -m pip install uv==0.11.23
+corepack enable
+pnpm install
+
+case "$(uname -s):$(uname -m)" in
+  Linux:x86_64) runtime_platform=linux-x64 ;;
+  Linux:aarch64|Linux:arm64) runtime_platform=linux-arm64 ;;
+  Darwin:arm64) runtime_platform=macos-arm64 ;;
+  *) echo "unsupported platform" >&2; exit 1 ;;
+esac
+
+pnpm exec tsx scripts/build-exe-for-python-sdk.ts --targets="node24-$runtime_platform"
+version="$(node -p "require('./package.json').version")"
+python scripts/build-python-release.py --package sdk --output-dir dist-python
+python scripts/build-python-release.py \
+  --package runtime \
+  --platform "$runtime_platform" \
+  --runtime-exe "dist-exe/dsh-jsonrpc-agent-pkg-$runtime_platform" \
+  --output-dir dist-python
+python -m pip install --find-links dist-python "deepseek-harness-sdk==$version"
+```
+
+运行时 wheel 包含 JSON-RPC 可执行文件，以及完整 [`minimal.cordis.yml`](../../../examples/jsonrpc-agent/minimal.cordis.yml) 使用的每个插件，因此两种安装方式完成后都不再需要 Node.js。
+
+## 运行仓库内置示例
+
+请在环境中设置凭据。如果模型不是由默认 DeepSeek 端点提供，而是通过 OpenAI 兼容代理提供，还需要设置 `DEEPSEEK_BASE_URL`。
+
+```sh
+export DEEPSEEK_API_KEY=sk-your-key-here
+# export DEEPSEEK_BASE_URL=http://127.0.0.1:8000/v1
+```
+
+从仓库 checkout 运行一个任务：
+
+```sh
+python examples/jsonrpc-agent/minimal.py \
+  --workspace /absolute/path/to/workspace \
+  --session-root /absolute/path/to/sessions \
+  --session-id example-001 \
+  "Inspect the repository and fix the failing tests."
+```
+
+脚本会打印 assistant 的最终回复。会话根目录会收到 JSONL 会话日志，其中包含组装后的模型请求与每次工具调用。
+
+## 在自己的程序中使用 SDK
+
+该示例是以下 SDK 调用的轻量包装层：
+
+```python
+from pathlib import Path
+
+from deepseek_harness import DeepSeekHarness
+
+config = Path("examples/jsonrpc-agent/minimal.cordis.yml").resolve()
+workspace = Path("/absolute/path/to/workspace").resolve()
+sessions = Path("/absolute/path/to/sessions").resolve()
+
+with DeepSeekHarness(
+    provider="deepseek-official",
+    model="deepseek-v4-flash",
+    max_tokens=49_152,
+    cwd=str(workspace),
+    session_root=str(sessions),
+    cordis=str(config),
+) as harness:
+    result = harness.run(
+        "Inspect the repository and fix the failing tests.",
+        session_id="example-001",
+    )
+
+print(result.final_response)
+```
+
+`DeepSeekHarness` 会延迟启动内置 JSON-RPC 运行时，并持续复用，直至退出上下文管理器。在多次调用中复用同一个 harness 和 session id，还会保留该会话拥有的 Bash 进程，包括其工作目录、已导出的变量与 shell 函数。
+
+## 了解示例配置
+
+| 方面 | 固定值 |
+|---|---|
+| 系统提示词 | `You are a helpful software engineer assistant.` |
+| 面向模型的工具 | 仅持久 `bash` 与 `str_replace_editor` |
+| Bash 超时 | 300 秒 |
+| 编辑器输出上限 | 16,000 个字符 |
+| 压缩 | 触发比例 `0.8`、保留 `20,480` 个 token、摘要上限 `8,192` 个 token、重试 1 次 |
+| 会话持久化 | `DSH_SESSION_ROOT` 下未压缩的 JSONL |
+
+该配置省略了 harness 身份、workspace 提示词文本、skill（技能）、一次性 Bash、任务工具和其他所有面向模型的插件。文件系统策略事实记录为运行时用户上下文，而不会追加到系统提示词中。编辑器无条件要求绝对路径，因此配置中没有已经废弃的 `requireAbsolutePath` 选项。
+
+## 选择 workspace 与 session id
+
+`cwd` 用于选择 agent 可访问的 workspace，`session_root` 用于保存会话日志和状态。独立任务应使用新的 session id；只有下一次调用需要延续同一段对话和持久 shell 状态时，才复用原有 id。
+
+该组合使用 `danger-full-access`。只能在可丢弃的 checkout 或容器内运行：Bash 与编辑器可以修改运行时进程有权访问的任何路径。持久 PTY 后端需要 POSIX 终端环境，因此该模式不适用于 Windows agent。
+
+完整的 SDK 生命周期与结果约定见 [Python SDK 参考](../../../python/sdk/README.md)。Cordis 组合语法见[配置](./config.md)。

+Bare plugin specifiers in a config (`@deepseek-ai/dsh-*`, npm packages) resolve through the Cordis Loader's internal module loader. They resolve from the config directory by default; a closed runtime passes `bareModuleBaseUrl` to `boot` or `mountRootInclude` so its installed package tree remains authoritative even when the config lives inside another Node project. Relative specifiers always resolve against the config directory. Repository bins install Loader's optional `node-addon-require-builtin` peer; external callers must supply it or install plugins where plain Node import resolution can find them.

 This package carries no loader hooks and no dev-mode surface. The [`dsh` app](../../../apps/cli/README.md) owns its Node source-launch hook and consumes these helpers for the boot sequence; built consumers continue to use plain Node package resolution.

 ### Key types
 
 - `AssembleContext` — what one `assemble()` call is FOR. Merge-extensible; declares `scope?: ScopeKey` (the layer selector) and `signal?: AbortSignal` (the explicit request control capability) here, while `dsh-agent` declares `agent?: Agent` (the typed DX field — never set without `scope`; use `assembleContextFor(agent, signal)`). Providers must tolerate absent fields because a bare `assemble()` carries an empty, scope-less, signal-less context. `signal` is a request value, not part of the ambient Agent execution frame.
-- `PromptSection` — `{ name, order, text }`. Sections are concatenated in ascending `order`. Order bands: `-100` is the harness identity, `0` the deployment persona, tool guidance uses `100–199`.
+- `PromptSection` — `{ name, order, text, complete? }`. Sections are concatenated in ascending `order`. Order bands: `-100` is the harness identity, `0` the deployment persona, tool guidance uses `100–199`. One effective `complete` section suppresses all other sections after cooperative assembly.
 - `PromptAssembly` — `{ sections: AssembledSection[], tools: ToolSchema[], variables: Record<string, string | undefined> }`. Section texts arrive resolved but not yet interpolated; `variables` holds every registered variable resolved against the context. Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.
 - `renderPrompt(assembly)` — interpolates `{{variable}}` references in each section, drops empty sections, joins with blank lines. STRICT: an unknown reference (`Object.hasOwn` lookup — prototype names like `{{constructor}}` are unknown), a registered-but-valueless reference, a malformed complete `{{…}}` group, or a `{{` that opens no complete group while a `}}` still follows (`{{{model}}}`) throws — fail loud beats shipping a malformed prompt. A lone `{{` with no `}}` anywhere after it passes through verbatim; substituted values are never re-scanned.

 #### What the model sees
 
-By default every assembly starts with the harness identity below, then the configured persona and ordered plugin sections after strict variable interpolation. `includeHarnessIdentity: false` omits only that fixed opener for a deployment that owns the complete compatibility persona. Empty sections disappear; scoped sections and variables can shadow globals for one agent. The final `system-prompt/assemble` waterfall result is authoritative, so an expert listener's changes determine the delivered prompt and tool schemas.
