DeepSeek Harness 插件:为自定义供应方(llm-pi-ai 手动添加的 provider)补上 DSH 官方渠道才有的能力,开箱即用、零逐模型配置。
A DeepSeek Harness plugin that gives custom providers (hand-added via the
llm-pi-ai provider) four capabilities official channels already have —
out of the box, with no per-model configuration.
兼容性:需要 DSH Desktop 2.0+(客户端 RPC 走 ctx.remote.settings)。
已对照 DSH Desktop 2.0.10(harness 0.1.2-alpha.1、cordis 4.0.2、
dsh-llm-pi-ai 0.1.5-rc.2)逐面核验:settings 服务与 RPC(含
expectedRevision CAS 写)、settings.section 槽、ModuleLoader bundle 协议、
设计令牌、pi-ai 推理词典语义、llm.stream/discoverModels 的 signal 透传。
主机侧三处整数组写(补档 / 容量回填+compat / 图片声明)已升级为
CAS + 冲突重试(mutate(ns, ops, expectedRevision))。
Requires DSH Desktop 2.0+ (the client half talks to ctx.remote.settings);
verified surface-by-surface against DSH Desktop 2.0.10 (harness 0.1.2-alpha.1,
cordis 4.0.2, dsh-llm-pi-ai 0.1.5-rc.2) — settings service & RPC incl. the
expectedRevision CAS write, the settings.section slot, the ModuleLoader
bundle protocol, design tokens, pi-ai reasoning-effort semantics, and
signal passthrough for llm.stream/discoverModels.

功能
- 自定义 User-Agent — 为每个自定义供应方设置请求 UA(覆盖内置 attribution 头),
应对按 UA 限流、或禁止非官方终端应用访问的供应方。
- 推理等级切换 — 与官方渠道一样的思考等级下拉。数据层自动完成:
Host 半自动为每个缺少
reasoningEfforts 的自定义模型写入五档词典
(off → null,low/medium/high/max → 同名值),
对话模型选择器随即出现推理等级行;
defaultEffort 不写 → 初始档位为 Default(请求不带思考参数,由供应方
自行决定)。切换发生在聊天里,无需设置。
- 图片输入声明 — 每个模型卡片内提供「支持图片输入」复选框,
勾选即写入
input: [text, image],DSH 随即允许向该模型附加图片。
- 一键全量探测与测活(内置)— 每个模型旁一个「探测」按钮,一次实测三项:
- 上下文窗口:调
/v1/models 拉取 contextWindow/maxTokens,
缺失字段自动回填(手工值不覆盖);
- 角色兼容:pi-ai 的 openai-completions 兼容层默认对推理模型发送
developer 角色(部分上游如 GLM 中转直接拒绝,报 1214「角色信息不正确」)。
探测发极小请求实测;被拒且 system 可用时自动写入
compat.supportsDeveloperRole: false(回退 system),即刻修复;
- 推理等级:不由探测判断;缺少
reasoningEfforts 的模型由自动补档器
恢复默认五档 off/low/medium/high/max,探测从不覆写该字典;
- 图片输入 + 延迟:通过 DSH LLM 运行时发送带 1×1 PNG 的真实流式
请求(最后一步,验证修复后的真实配置),报告首 token 延迟与图片接受,
并把结果同步到
input 声明(只增删 image,其他 modality 保留)。
写回(容量回填 + compat + 图片声明)各自在 mutate 前重新读取最新配置,
只写真正变化的字段,互不覆盖;流式探测 30s 预算内无首 token 判为失败,
不会误报存活。wire 检查仅对 openai-completions 路由生效。
供应商卡片头显示 可达/不可达/冷却/未测 徽章,模型行显示对应状态点;
「一键探测」对全部模型走同一全量探测(冷却中的模型跳过,保留上次结果)。
安装
# 方式一:git 安装(需要一次构建许可,见下)
dsh plugin --profile desktop add github:Mortal520/dsh-provider-pro
# 方式二:本地仓库 / tarball(免构建许可)
dsh plugin --profile desktop add ./dsh-provider-pro
dsh plugin --profile desktop add ./dsh-provider-pro-0.5.1.tgz # 先 pnpm pack
git 安装注意:pnpm ≥10 默认拒绝运行 git 依赖的构建脚本。首次 add 报错时,
把 pnpm 提示的那个包 key 写进 profile 的 pnpm-workspace.yaml:
allowBuilds:
dsh-provider-pro: true
然后重跑 add。这是对包内代码在你机器上执行的一次性授权——只允许可信来源,
并建议锁定提交(github:Mortal520/dsh-provider-pro#<sha>)。
为避免该步骤,本仓库已提交构建产物 lib/,也可直接用 tarball/本地路径安装。
安装后**重启 dsh web(DSH Desktop 需重启应用)**生效。
用法(设置 → 模型增强)
在「模型」下方新增的原生设置页(与官方页同款令牌样式):
- 总开关「为全部自定义模型启用推理等级切换」(默认开):控制功能 2。
关闭时,自动补全的档位会被移除、回到供应方默认;你在别处手动设过的等级不受影响。
- 每个供应方一张 User-Agent 卡:填写后保存,发往该供应方 baseURL 前缀的请求
带上此 UA;留空保存即清除覆盖。
平台红线(第三方插件无法突破)
对话模型选择器内部的档位名是 dsh-llm-pi-ai 硬编码英文
(Off / Minimal / … / Max,reasoningInfo() 在 dsh-llm-pi-ai/lib/index.js 写死),
第三方插件无法为其改语言,defaultEffort 也不接受中文名值。中文能力只覆盖本插件的
设置页。若需要选择器内中文化,只能改 dsh-llm-pi-ai 本体。
实现原理(给维护者)
- 推理等级(数据层):完整
reasoningEfforts 词典 → pi-ai resolveModelReasoning
→ 模型 reasoning = { thinkingLevelMap 全 5 档 } → ModelSelect 的 Effort 行天然出现;
defaultEffort 留空 → 选择器自动前置「Default」并默认选中。
- 总开关:
llm-pi-ai 用户层顶层的 dshProviderProAutoReasoning(缺省 = 开),
Host 补档器每次扫描前检查该标志;客户端点开关一次性写入
标志 + 移除字节级相同的自动补档词典。
- UA:pi-ai 会过滤用户
headers 里任意大小写的 user-agent、再追加 attribution 头
(requestHeaders()),改 settings.headers 是死路。Host 半在宿主进程对
globalThis.fetch 做一次 URL 前缀匹配的最小补丁:仅当请求 URL 命中某供应方 baseURL、
且该供应方配置了 userAgent(存于 llm-pi-ai.providers.<route>.userAgent,
schema 非严格保字段、适配器不读)时替换(而非追加)User-Agent。
- 区块:
settings.section 槽,id: provider-pro、order: 15(官方「模型」=10)。
构建与验证
pnpm install
pnpm run check # 类型检查 + 构建 + 离线产物校验
pnpm run smoke # Host 行为冒烟(fetch 补丁 / 补档器 / 总开关 / UA 边界 / 探测消费者)
pnpm run verify # 上面全部 + 打包(prepack)
lib/ 是发布产物,已提交进仓库(git 安装免重建即可用)。
注:check/smoke 验证的是构建产物与 Host 半逻辑;不覆盖真实 profile 安装、
客户端 UI 渲染或真实网关探测。修改涉及探测或写入路径后,建议对实际网关再跑一次
全量探测,并重启桌面端验证设置页行为。
已知限制
- 选择器内档位名 =
dsh-llm-pi-ai 硬编码英文,无法中文化(见「平台红线」)。
- 补档器只在
llm-pi-ai namespace 内、手声明 models[] 的条目生效;
不触碰 modelOverrides 与官方渠道(catalog)。

Features
- Custom User-Agent — set a request-level UA per custom provider
(overrides DSH's built-in attribution header). Handles providers that
rate-limit by UA or reject non-official terminal apps.
- Reasoning-level switching — the same reasoning picker as the official
channels (off / low / medium / high / max). Fully data-driven, no per-model
setup: the host fills a five-level
reasoningEfforts dictionary for every
hand-declared custom model that lacks one and keeps defaultEffort unset,
so the picker preselects Default (no thinking parameter is sent; the
provider decides). Switch levels any time in chat.
- Image-input declaration — each model card shows a "Support image input"
checkbox; checking it writes
input: [text, image] so DSH allows image
attachments for that model.
- One-button full probe & liveness — each model row has a single
"Probe" button that measures everything in one pass:
- Context window: calls
/v1/models for contextWindow/maxTokens
and backfills missing fields (hand-set values are never overwritten).
- Message-role compat: pi-ai's openai-completions layer defaults to
sending OpenAI's
developer role for reasoning-capable models — which
some upstreams (GLM behind a relay, error 1214) refuse. A minimal wire
request verifies it; when developer is refused while system passes,
compat.supportsDeveloperRole: false is written automatically.
- Reasoning levels: not probed. Models lacking a
reasoningEfforts
dictionary get the default five-level dict (off / low / medium / high /
max) from the auto-fill pass; the probe never overwrites it.
- Image input + latency: a real stream carrying a 1×1 PNG through
DSH's LLM runtime (run last, exercising the exact post-fix config)
reports first-token latency and image admission, and syncs the
input declaration (adds/removes only image; other declared
modalities are preserved). A stream that yields no first token within
the 30s budget is an explicit failure, never a false "alive".
Each write-back (backfill + compat + image declaration) re-reads the
freshest settings right before its mutate and writes only fields that
actually changed. Wire checks apply only to openai-completions routes.
Provider card headers show an up/down/cooldown/untested badge and each
model row a matching status dot, aggregated from the latest results
("Probe all" skips models with an active cooldown and keeps their
previous result).
Install
# git install (needs one build allow, see note)
dsh plugin --profile desktop add github:Mortal520/dsh-provider-pro
# or a local checkout / tarball (no build permission needed)
dsh plugin --profile desktop add ./dsh-provider-pro
dsh plugin --profile desktop add ./dsh-provider-pro-0.5.1.tgz # after pnpm pack
git installs run the package's prepare script. pnpm ≥10 blocks that until
you allow it: copy the package key pnpm prints into the profile's
pnpm-workspace.yaml (allowBuilds: dsh-provider-pro: true) and re-run
add. Only allow packages you trust — and preferably pin a commit
(github:Mortal520/dsh-provider-pro#<sha>).
To avoid that step entirely, this repo commits its built lib/, and
tarball/local installs need no build permission at all.
Restart dsh web after installing.
Usage (Settings → 模型增强)
A native settings section right below the official 模型 page:
- Master switch "Enable reasoning-level switching for all custom models"
(on by default) — controls feature 2. Turning it off strips only the
auto-filled dictionaries (byte-identical ones) and leaves any level you set
manually untouched.
- One User-Agent card per provider — save to apply the UA to requests
whose URL starts with that provider's baseURL; empty + save clears it.
Platform red line
Effort-level names inside the model picker are hardcoded English in
dsh-llm-pi-ai and cannot be localized by a third-party plugin; our Chinese
labels cover this plugin's own settings section only. In-picker Chinese
requires patching dsh-llm-pi-ai itself.
Build & verify
pnpm install
pnpm run check # typecheck + build + offline artifact validation
pnpm run smoke # host smoke tests (fetch patch / filler / master switch / UA boundary / probe consumer)
pnpm run verify # the above plus a tarball pack (prepack)
lib/ is the build artifact and is committed, so a git install works without
building.
Note: check/smoke validate the build output and the host-half logic;
they do not cover a real profile install, client-UI rendering, or a live
gateway probe. After changing the probe or write paths, re-run a full probe
against your actual gateway and restart the desktop app to verify the
settings page behavior.
Known limitations
- In-picker effort names are English-only (see platform red line).
- The filler only touches hand-declared
models[] under the llm-pi-ai
namespace; it never touches modelOverrides or catalog models.
