Its import package is `deepseek_harness`; the SDK depends on `deepseek-harness-runtime-bin==0.1.5rc1`, which contains the bundled `dsh` executable for supported platforms. The SDK requires an explicit `dsh_home` or non-empty `DSH_HOME`; it never falls back to `~/.dsh`. `DeepSeekHarness` starts its subprocess lazily and reuses it across `run()` calls. + +Live SDK inspection on 2026-10-15 showed that the packaged DSH profile can start with the native provider name `deepseek-official`, while `volcengine`, `ark`, `volcengine-ark`, `openai`, `openai-compatible`, `third-party`, `doubao`, and `deepseek` are not registered DSH adapter names in the current wheel. VeADK therefore owns user-facing provider aliases for Volcengine and third-party OpenAI-compatible endpoints and maps them to the DSH adapter that currently accepts explicit `base_url` and `api_key`. + +Assumptions that remain intentionally bounded: + +- DSH native tool plugins are registered through the documented Cordis `ctx.tools.register(defineTool(...))` extension path. +- DSH skills are registered through the documented native `@deepseek-ai/dsh-skill`, `@deepseek-ai/dsh-skill-filesystem`, and `@deepseek-ai/dsh-tool-skill` plugins. +- DSH notifications are mapped for root-session assistant stream chunks and native tool call/result events; descendant session notifications are retained for future expansion but do not replace the root final response. + +## Goals + +- Add `runtime="dsh"` as a public Python SDK runtime value. +- Install DSH through a VeADK optional extra that depends on the Python SDK and its transitive runtime binary package. +- Start DSH lazily on first turn, not at import or `Agent(...)` construction time. +- Reuse a long-lived DSH SDK object per effective runtime configuration, with stable DSH session IDs derived from VeADK app/user/session/agent identity. +- Bridge ADK function tools and ADK/MCP toolsets into DSH as native tools through a generated DSH plugin and a local authenticated Python callback server. +- Bridge ADK sub-agent transfer through the same injected `transfer_to_agent` tool used by other external runtimes. +- Bridge ADK `SkillToolset` and legacy VeADK skills through DSH's native filesystem skill provider and `skill` loader tool. +- Stream DSH assistant deltas and native tool call/result events back as ADK events while preserving after-model callback semantics for the final response. +- Keep VeADK/ADK session history as the short-term memory source of truth by serializing visible session history into DSH prompts, matching the Codex runtime contract. +- Honor model changes made by before-model callbacks when selecting the DSH SDK config and cached manager. +- Use an explicit isolated `DSH_HOME` by default, with a configuration override for persistent deployments. +- Support omitted provider values and user-facing `openai`, `volcengine`, `volcengine-ark`, `ark`, `openai-compatible`, and `third-party` provider aliases without requiring callers to know the current DSH adapter name. +- Provide clear errors when the optional extra is missing. +- Document the lifecycle differences from Codex and PiAgent. + +## Non-goals + +- Do not build a custom VeADK first-run downloader for the `dsh` binary. +- Do not claim ADK `enable_skills_checklist` enforcement inside DSH's native skill loader. +- Do not implement a complete UI projection for descendant DSH subagent session notifications in this change. +- Do not add frontend Studio DeepSeek Harness behavior; Studio already has a separate DeepSeek Harness sandbox path. +- Do not run live provider calls as part of ordinary unit tests. + +## Scenarios and Requirements + +- **FR-1 — Runtime selection.** Given an agent constructed with `runtime="dsh"`, when it runs, VeADK dispatches to the DSH runtime instead of the ADK LLM flow. +- **FR-2 — Optional dependency boundary.** Given a default VeADK installation without DSH, when code resolves the runtime, the error names the missing extra and installation command. +- **FR-3 — Binary acquisition.** Given `veadk-python[dsh]` is installed, the matching `dsh` binary is acquired through `deepseek-harness-runtime-bin`; VeADK performs no runtime download. +- **FR-4 — Lazy startup.** Given a process imports VeADK or constructs an agent, DSH is not started until a turn reaches `DeepSeekHarnessRuntime.run_async`. +- **FR-5 — Session identity.** Given repeated turns for the same `app_name`, `user_id`, `session_id`, and agent name, VeADK passes the same DSH `session_id`. +- **FR-6 — Isolated home.** Given no `dsh_home` is configured, VeADK creates an explicit process-owned `DSH_HOME` under a temporary root and passes it to the SDK. +- **FR-7 — Callback compatibility.** Given model callbacks are configured, before/after/error model callbacks fire at the same coarse per-turn boundary used by other external runtimes. +- **FR-8 — Tool bridge.** Given ADK function tools or ADK/MCP toolsets are configured, VeADK exposes them as DSH native tools through `defineTool`, executes them in Python, and emits the corresponding ADK tool events. +- **FR-9 — Sub-agent transfer.** Given transfer-capable `sub_agents` are configured, VeADK exposes `transfer_to_agent`; when DSH calls it, VeADK runs the target agent and suppresses the DSH final text for that turn. +- **FR-10 — Skill bridge.** Given ADK `SkillToolset` or legacy VeADK skills are configured, VeADK materializes them to an isolated skill root, registers DSH's native skill plugins with `includeDefaultRoots=false`, and includes the skill content digest in the manager key. +- **FR-11 — Event mapping.** Given DSH emits root-session assistant stream chunks or native tool call/result events, VeADK maps them to ADK partial model events and function call/response events without duplicating VeADK-bridged Python tool events. +- **FR-12 — Codex-aligned short-term context and model callbacks.** Given ADK session history exists, DSH receives it as structured conversation data in the prompt. Given a before-model callback mutates `llm_request.model`, DSH uses the mutated model for manager selection and SDK config. +- **FR-13 — Honest limitations.** Given unsupported ADK flow features, VeADK warns or errors through the existing runtime support matrix and documentation rather than silently claiming equivalence. +- **FR-14 — Provider aliases.** Given config `provider` is omitted, blank, `openai`, `volcengine`, `volcengine-ark`, `ark`, `openai-compatible`, or `third-party`, VeADK resolves a valid user-facing configuration and passes DSH the currently registered OpenAI-compatible adapter provider. + +## Design and Contract Impact + +The selected design matches Codex's dependency-acquisition model: add a `dsh` optional extra that pins `deepseek-harness-sdk==0.1.5rc1`, letting that package bring the matching runtime binary wheel. This is preferred over the PiAgent-style first-run downloader because DSH already publishes an SDK/runtime-bin pair, so VeADK should not duplicate platform selection, cache management, and version coupling logic. + +The runtime package is `veadk.runtime.deepseek_harness`. Its public config class is `DeepSeekHarnessRuntimeConfig`. `Agent` gains `deepseek_harness_runtime_config`, accepting either that config or a dict. + +Effective DSH configuration resolves as: + +1. Agent `deepseek_harness_runtime_config`. +2. Narrow environment overrides with the `VEADK_DEEPSEEK_HARNESS_*` prefix. +3. Agent model fields for model name, API base, and API key when no DSH-specific override is set. +4. Conservative defaults (`provider="deepseek-official"`, `profile="sdk-minimal"`). `sdk-minimal` lets VeADK inject the DSH tool and skill plugins it owns, while a caller may still opt into DSH's fuller `sdk` profile. + +Provider handling is intentionally two-layered. `DeepSeekHarnessRuntimeConfig.provider` remains the user-facing provider name. Blank provider values normalize to `deepseek-official`. The runtime maps the aliases `openai`, `volcengine`, `volcengine-ark`, `ark`, `openai-compatible`, and `third-party` to DSH's current `deepseek-official` adapter before constructing `DeepSeekHarnessConfig`. Unknown provider names are passed through so future DSH-native providers can work without a VeADK release. + +State and lifecycle: + +- One `DeepSeekHarness` manager is cached per effective process configuration. +- The manager starts lazily and is closed at interpreter exit. +- A generated `DSH_HOME` lives under a process-owned temp root unless `dsh_home` is configured. +- The manager key includes the bridged DSH tool schema digest. Each manager owns a long-lived localhost tool bridge and a generated DSH plugin patch when tools are present. +- The manager key includes the materialized skill content digest. Each manager owns its DSH skill patch and skill root when skills are present. +- Turns on the same manager are serialized. During one active turn, the manager binds the current ADK tool bundle to its bridge and clears it after the SDK call returns. +- The DSH session id is a SHA-256 based stable ID over VeADK app/user/session/agent identity. +- The DSH prompt serializes the callback-visible `LlmRequest.contents` into structured prior conversation and current-message blocks. This keeps ADK session history, not DSH's private session state alone, as the portable short-term memory contract shared with Codex. + +Security: + +- The SDK subprocess inherits the process environment by default, matching DSH SDK behavior. Configured `env`, `base_url`, and `api_key` are explicit overrides. +- The runtime does not invent a sandbox policy. DSH profile behavior is owned by DSH. +- Tool bridge calls are accepted only on loopback and require a per-manager bearer token embedded in the generated DSH plugin. +- The generated `DSH_HOME` avoids implicit writes to `~/.dsh`. + +Compatibility: + +- Existing `adk`, `codex`, and `piagent` behavior is unchanged. +- The new runtime is opt-in by both runtime value and extra dependency. +- Missing extra failures are import-time-on-resolution, not package import failures. + +Component contract impact: a new component spec is required because this changes public runtime values, optional dependency behavior, session state, sidecar lifecycle, and configuration semantics. + +## Implementation Tasks + +- **T-1:** Add bilingual PRD/spec entries for the runtime contract. Covers `FR-1` through `FR-8`. +- **T-2:** Add the optional dependency extra and lock metadata.

OpenAI-compatible provider 别名，再把它们映射到当前接受显式 `base_url` 和 `api_key` 的 DSH adapter。 + +本变更刻意收窄的假设： + +- DSH 原生工具插件通过已文档化的 Cordis `ctx.tools.register(defineTool(...))` 扩展路径注册。 +- DSH skills 通过已文档化的原生

行为；Studio 已有独立的 DeepSeek Harness sandbox 路径。 +- 普通单元测试不执行真实 provider 调用。 + +## 场景与需求 + +- **FR-1 — Runtime 选择。** 给定使用 `runtime="dsh"` 构造的 agent，当它运行时，VeADK 调度到 DSH runtime，而不是 ADK LLM flow。 +- **FR-2 — 可选依赖边界。** 给定默认 VeADK 安装中没有 DSH，当代码解析该 runtime 时，错误信息说明缺少 extra 和安装命令。 +- **FR-3 — 二进制获取。** 给定安装了 `veadk-python[dsh]`，匹配的 `dsh` 二进制通过 `deepseek-harness-runtime-bin` 获得；VeADK 不做运行时下载。 +- **FR-4 — 懒启动。** 给定进程 import VeADK 或构造 agent，直到 turn 到达 `DeepSeekHarnessRuntime.run_async` 前 DSH 都不会启动。 +- **FR-5 — Session 身份。** 给定相同 `app_name`、`user_id`、`session_id` 和 agent 名称的重复 turn，VeADK 传入相同 DSH `session_id`。 +- **FR-6 — 隔离 home。** 给定未配置 `dsh_home`，VeADK 在临时 root 下创建显式、进程所有的 `DSH_HOME` 并传给 SDK。 +- **FR-7 — Callback 兼容。** 给定配置了 model callback，before/after/error model callback 在与其他外部 runtime 相同的粗粒度 per-turn 边界执行。 +- **FR-8 — 工具桥接。** 给定配置了 ADK function tools 或 ADK/MCP toolsets，VeADK 通过 `defineTool` 暴露为 DSH 原生工具，在 Python 侧执行，并输出对应 ADK tool events。 +- **FR-9 — 子智能体转交。** 给定配置了可转交的 `sub_agents`，VeADK 暴露 `transfer_to_agent`；当 DSH 调用它时，VeADK 运行目标 agent，并抑制该 turn 的 DSH 最终文本。 +- **FR-10 — Skill 桥接。** 给定配置了 ADK `SkillToolset` 或 legacy VeADK skills，VeADK 会把它们物料化到隔离 skill root，通过 `includeDefaultRoots=false` 注册 DSH 原生 skill 插件，并把 skill 内容 digest 纳入 manager key。 +- **FR-11 — Event 映射。** 给定 DSH 输出 root-session assistant stream chunks 或原生 tool call/result events，VeADK 会映射为 ADK partial model events 和 function call/response events，并避免重复输出 VeADK 桥接的 Python tool events。 +- **FR-12 — Codex 对齐的短期上下文与模型 callback。** 给定存在 ADK session history，DSH 会在 prompt 中收到结构化 conversation data。给定 before-model callback 修改 `llm_request.model`，DSH 会用修改后的模型选择 manager 和 SDK config。 +- **FR-13 — 如实表达限制。** 给定不支持的 ADK flow 能力，VeADK 通过现有 runtime 支持矩阵和文档告警或报错，而不是默默宣称等价。 +- **FR-14 — Provider 别名。** 给定 config `provider` 未填写、为空、为 `openai`、`volcengine`、`volcengine-ark`、`ark`、`openai-compatible` 或 `third-party`，VeADK 会解析成有效的用户侧配置，并传给 DSH 当前已注册的 OpenAI-compatible adapter provider。 + +## 设计与契约影响 + +选定设计与 Codex 的依赖获取模式一致：新增 `dsh` optional extra，固定依赖 `deepseek-harness-sdk==0.1.5rc1`，由该包带入匹配的 runtime binary wheel。它优于 PiAgent 风格的首次运行下载器，因为 DSH 已经发布 SDK/runtime-bin 配对，VeADK 不应重复实现平台选择、缓存管理和版本耦合。 + +runtime 包路径为 `veadk.runtime.deepseek_harness`。公开配置类为 `DeepSeekHarnessRuntimeConfig`。`Agent` 增加 `deepseek_harness_runtime_config`，接受该配置或 dict。 + +有效 DSH 配置按以下顺序解析： + +1. Agent 的 `deepseek_harness_runtime_config`。 +2. `VEADK_DEEPSEEK_HARNESS_*` 前缀的窄环境变量覆盖。 +3. 未设置 DSH 专用覆盖时，使用 agent 的 model name、API base 和 API key。 +4. 保守默认值（`provider="deepseek-official"`、`profile="sdk-minimal"`）。`sdk-minimal` 让 VeADK 注入它自己负责的 DSH tool 和 skill 插件；调用方仍可显式选择 DSH 更完整的 `sdk` profile。 + +Provider 处理刻意分成两层。`DeepSeekHarnessRuntimeConfig.provider` 保持用户可见 provider 名称。空 provider 值会归一成 `deepseek-official`。Runtime 在构造 `DeepSeekHarnessConfig` 前，把 `openai`、`volcengine`、`volcengine-ark`、`ark`、`openai-compatible` 和 `third-party` 映射到当前 DSH 的 `deepseek-official` adapter。未知 provider 名会原样透传，让未来 DSH 原生 provider 不需要等待 VeADK 发版也能工作。 + +状态与生命周期： + +- 每个有效进程配置缓存一个 `DeepSeekHarness` manager。 +- manager 懒启动，并在解释器退出时关闭。 +- 除非配置 `dsh_home`，生成的 `DSH_HOME` 位于进程拥有的临时 root 下。 +- Manager key 包含已桥接 DSH tool schema 的 digest。存在工具时，每个 manager 拥有长期本地 tool bridge 和生成的 DSH plugin patch。 +- Manager key 包含已物料化 skill 内容的 digest。存在 skills 时，每个 manager 拥有 DSH skill patch 和 skill root。 +- 同一 manager 内的 turn 串行执行。每个活跃 turn 会把当前 ADK tool bundle 绑定到该 bridge，SDK 调用返回后清理绑定。 +- DSH session id 是基于 VeADK app/user/session/agent 身份计算的 SHA-256 稳定 ID。 +- DSH prompt 会把 callback 可见的 `LlmRequest.contents` 序列化为结构化的历史 conversation 和 current-message blocks。这让 ADK session history，而不是只靠 DSH 私有 session state，成为与 Codex 共享的可移植短期记忆契约。 + +安全： + +- SDK 子进程默认继承进程环境，保持 DSH SDK 行为。配置的 `env`、`base_url` 和 `api_key` 是显式覆盖。 +- runtime 不发明沙箱策略。DSH profile 行为由 DSH 拥有。 +- Tool bridge 只接受 loopback 调用，并要求生成的 DSH 插件携带 per-manager bearer token。 +- 生成的 `DSH_HOME` 避免隐式写入 `~/.dsh`。 + +兼容性： + +- 现有 `adk`、`codex` 和 `piagent` 行为不变。 +- 新 runtime 需要 runtime 取值和 extra 依赖双重显式选择。 +- 缺少 extra 的失败发生在解析 runtime 时，不影响包 import。 + +组件契约影响：本变更改变公开 runtime 取值、optional dependency 行为、session 状态、sidecar 生命周期和配置语义，因此需要新增组件规格。 + +## 实施任务 + +- **T-1：** 新增双语 PRD/spec，定义 runtime 契约。覆盖 `FR-1` 至 `FR-8`。 +- **T-2：** 新增 optional dependency extra 并同步 lock 元数据。覆盖 `FR-2`、`FR-3`。 +- **T-3：** 扩展 `Agent.runtime`、新增 `deepseek_harness_runtime_config`，并从 `veadk.runtime.get_runtime` 调度。覆盖 `FR-1`、`FR-2`。 +- **T-4：** 实现 `veadk.runtime.deepseek_harness` 的 config、manager、prompt 转换、生成式 DSH 工具插件、本地工具桥、原生 skill patch、event translator 和 runtime。覆盖 `FR-4` 至 `FR-12`。 +- **T-5：** 扩展 runtime 兼容性警告/错误。覆盖 `FR-13`。 +- **T-6：** 使用 fake `deepseek_harness` module 增加单元测试，不要求真实 binary。覆盖 `FR-1` 至 `FR-12`。 +- **T-7：** 更新中英文 runtime 文档。覆盖 `FR-2`、`FR-3`、`FR-8`、`FR-10` 至 `FR-14`。 + +## 验证与验收 + +| 需求 | 任务 | 验收标准 | 测试或验证命令 | 结果/证据 |

`runtime-deepseek-harness` +- **Status:** active +- **Revision date:** 2026-10-15 +- **Owned code:** `veadk/runtime/deepseek_harness/`, `veadk/runtime/__init__.py`, `veadk/agent.py` runtime fields, runtime support matrix entries. +- **Primary tests:** `tests/runtime/deepseek_harness/` +- **Related PRD:** [DSH Runtime](../../prd-spec/features/deepseek-harness-runtime/2026-10-15-deepseek-harness-runtime.md) +- **Dependent components:** Agent execution, runtime compatibility, optional dependency metadata, user runtime documentation. + +## Responsibility and Non-goals + +This component owns the Python SDK bridge between `Agent(runtime="dsh")` and the local DeepSeek Harness SDK runtime. It resolves runtime configuration, manages the long-lived SDK object and explicit `DSH_HOME`, maps VeADK session identity to DSH session identity, bridges ADK/MCP tools through DSH native tool plugins, bridges skills through DSH's native filesystem skill provider, and emits ADK-compatible partial, tool, and final response events. + +It does not own DSH profile behavior, provider authentication semantics inside DSH, the bundled binary build pipeline, Studio's separate DeepSeek Harness sandbox flow, ADK skill checklist enforcement inside DSH's native skill loader, or descendant-session UI projection. + +## Entry Points and Dependencies + +- Public runtime value: `Agent(runtime="dsh")`. +- Public config import: `from veadk.runtime.deepseek_harness import DeepSeekHarnessRuntimeConfig`. +- Optional dependency: `veadk-python[dsh]`, which installs `deepseek-harness-sdk==0.1.5rc1` and the matching transitive `deepseek-harness-runtime-bin`. +- External SDK import: `deepseek_harness`. +- Runtime dispatch: `veadk.runtime.get_runtime("dsh")`. + +## Contract + +- **CON-1 — Runtime value.** `dsh` is the stable public runtime identifier. Unknown spellings are rejected by `Agent` or `get_runtime`. +- **CON-2 — Optional dependency.** Importing VeADK without the DSH extra succeeds. Resolving the DSH runtime without the SDK raises `ImportError` with `pip install "veadk-python[dsh]"`. +- **CON-3 — Config source.** `deepseek_harness_runtime_config` accepts a `DeepSeekHarnessRuntimeConfig` instance or dict. Environment variables with the `VEADK_DEEPSEEK_HARNESS_*` prefix override matching fields. +- **CON-4 — Model resolution.** If config `model` is unset, the runtime uses the first `Agent.model_name` entry. ADK before-model callbacks may mutate `llm_request.model`; the mutated model is used when selecting the DSH manager and SDK config. +- **CON-4a — Provider aliases.** Config `provider` is the user-facing provider name and defaults to `deepseek-official`; blank values normalize to that default. The aliases `openai`, `volcengine`, `volcengine-ark`, `ark`, `openai-compatible`, and `third-party` are mapped to the current DSH `deepseek-official` adapter before SDK construction. Unknown provider names are passed through unchanged for future DSH-native adapters. +- **CON-5 — Lazy sidecar.** No DSH subprocess starts during module import, runtime lookup, or agent construction. The SDK object starts from the first actual turn. +- **CON-6 — Explicit home.** When `dsh_home` is unset, the runtime creates and passes a non-empty generated DSH home. It never relies on implicit `~/.dsh`. +- **CON-7 — Session mapping and short-term context.** DSH `session_id` is stable for the tuple `(app_name, user_id, session_id, agent name)`. The prompt also serializes the visible ADK session history into a structured `` block, keeping VeADK/ADK session state as the short-term memory source of truth rather than relying only on DSH's internal session state. +- **CON-8 — Tool bridge.** ADK function tools and ADK/MCP toolsets are expanded before the DSH run, registered as DSH native tools through a generated `defineTool` plugin patch, executed in Python through an authenticated loopback bridge, and emitted as ADK tool call/response events. +- **CON-9 — Sub-agent transfer.** Transfer-capable `sub_agents` are exposed through the injected `transfer_to_agent` tool. A transfer response runs the target agent and suppresses the DSH final text for that turn. +- **CON-10 — Skill bridge.** ADK `SkillToolset` and legacy VeADK skills are materialized into an isolated skill root. The runtime registers `@deepseek-ai/dsh-skill`, `@deepseek-ai/dsh-skill-filesystem` with `includeDefaultRoots=false`, and `@deepseek-ai/dsh-tool-skill` through a DSH patch. The materialized skill content digest participates in the manager key. +- **CON-11 — Event mapping.** Root-session DSH assistant stream chunks are emitted as ADK partial model events. DSH native `tool/call` and `tool/result` events are emitted as ADK function call/response events, excluding VeADK-bridged Python tool names to avoid duplicates. +- **CON-12 — Event output.** Each completed non-transfer DSH run emits one ADK model event containing `RunResult.final_response` after ADK after-model callbacks. Empty DSH final responses are represented as an empty final model response. +- **CON-13 — Unsupported surfaces.** ADK flow-only features remain covered by `veadk.runtime.compat`. ADK skill checklist enforcement and full descendant-session projection are not part of this component's active contract. + +## State and Concurrency + +Effective runtime configurations are keyed after resolving model, provider, DSH profile, homes, paths, timeouts, explicit environment overrides, the bridged DSH tool schema digest, and the materialized skill content digest. Each key owns one `DeepSeekHarness` instance, one generated `dsh_home` when applicable, one long-lived tool bridge/plugin patch when tools are present, and one native DSH skill patch/root when skills are present. Tool plugin files are written under a manager-private temporary directory, not under shared `dsh_home`, so persistent homes can be reused across processes without overwriting the per-process bridge token. Managers are closed at process exit. + +Turns sharing a manager are serialized with an async lock. This avoids undocumented concurrent access to one SDK stdio client. Multiple different manager keys may run independently. + +Cancellation from the surrounding task cannot reliably cancel one in-flight DSH `run()` call through the current synchronous SDK. The component preserves the shared manager and keeps its lock until the synchronous SDK call returns, then propagates cancellation. It does not claim graceful per-turn cancellation. + +Tool bridge calls are accepted only while the manager lock owns an active turn. The bridge rejects calls without the per-manager bearer token or without an active ADK tool bundle. + +## Data and Configuration + +Configuration fields: + +- `provider`, `model`, `reasoning_effort`, `max_tokens` +- `cwd`, `runtime_cwd`, `dsh_bin`, `profile`, `patches`, `dsh_home` +- `env`, `initialize_timeout_seconds`, `request_timeout_seconds`, `shutdown_timeout_seconds` +- `base_url`, `api_key` + +Environment overrides: + +- `VEADK_DEEPSEEK_HARNESS_PROVIDER` +- `VEADK_DEEPSEEK_HARNESS_MODEL` +- `VEADK_DEEPSEEK_HARNESS_REASONING_EFFORT` +- `VEADK_DEEPSEEK_HARNESS_MAX_TOKENS` +- `VEADK_DEEPSEEK_HARNESS_CWD` +- `VEADK_DEEPSEEK_HARNESS_RUNTIME_CWD` +- `VEADK_DEEPSEEK_HARNESS_DSH_BIN` +- `VEADK_DEEPSEEK_HARNESS_PROFILE` +- `VEADK_DEEPSEEK_HARNESS_DSH_HOME` +- `VEADK_DEEPSEEK_HARNESS_INITIALIZE_TIMEOUT_SECONDS` +- `VEADK_DEEPSEEK_HARNESS_REQUEST_TIMEOUT_SECONDS` +- `VEADK_DEEPSEEK_HARNESS_SHUTDOWN_TIMEOUT_SECONDS` +- `VEADK_DEEPSEEK_HARNESS_BASE_URL` +- `VEADK_DEEPSEEK_HARNESS_API_KEY` + +The default `profile` is `sdk-minimal`, so VeADK can inject the exact DSH tool and skill plugins it owns. Callers may opt into DSH's fuller `sdk` profile; in that mode VeADK patches the existing skill filesystem plugin configuration rather than inserting a duplicate plugin set. + +`request_timeout_seconds` defaults to `None`, which leaves the SDK run unbounded at the VeADK layer. Production callers should set it when a hard turn deadline is required. + +## Security and Isolation + +Generated `DSH_HOME` paths are process-owned temporary directories. Configured `dsh_home`, `cwd`, and `runtime_cwd` are expanded and resolved before use. The runtime passes `api_key` and `base_url` only through SDK config; redaction of DSH internals belongs to DSH. + +User prompts and session IDs are untrusted input. Session IDs are hashed rather than embedded raw into DSH identifiers. + +## Compatibility and Evolution + +The component is additive. Existing runtime values and configs remain unchanged. Future versions may add checklist enforcement, descendant-session projection, and finer cancellation only after the PRD/spec contract is updated and covered by tests. + +## Observability and Failures + +The runtime logs selected model/provider and session identity at a non-secret level. SDK import errors, initialization errors, and run errors propagate unless an ADK on-model-error callback returns a fallback `LlmResponse`. + +## Verification + +| Contract | Guarantee | Test or
