@volcengine/ark-plan-api

A DeepSeek Harness (DSH) cordis plugin that registers Volcengine Ark model provider routes on the native llm-pi-ai adapter. After install and an API key, Ark Agent Plan, Coding Plan and postpaid models appear directly in DSH's model picker — no extra configuration beyond pasting the key.

火山方舟模型路由插件。在 DSH 原生模型选择器中注册方舟 Agent Plan、Coding Plan 与后付费模型路由；安装后填入 API Key 即可使用，无需额外配置。

Features / 功能

  • Agent Plan — doubao-seed-evolving, doubao-seed-2.1-pro, deepseek-v4-pro and more via the Agent Plan endpoint.
  • Coding Plan — Coding-optimized models for both cn-beijing and BytePlus regions.
  • Postpaid (后付费) — Direct pay-as-you-go access to Ark foundation models.
  • Native picker integration — All providers show up alongside built-in ones in Settings → Models, no model IDs to memorize.
  • Anthropic Messages wire protocol — Uses the same Messages API shape DSH uses for Anthropic, so tool use, vision and streaming work out of the box.

Install / 安装

From npm (recommended / 推荐)

npx -y @deepseek-ai/dsh plugin --profile web add @volcengine/ark-plan-api

From GitHub Release

npx -y @deepseek-ai/dsh plugin --profile web add https://github.com/volcengine/ark-cli/releases/download/dsh-plugins%2Fv0.1.0/ark-plan-api.tgz

Via awesome-dsh-plugin registry

npx -y @deepseek-ai/dsh plugin --profile web add volcengine/ark-cli#ark-plan-api

From a local clone (development / 开发用)

npx -y @deepseek-ai/dsh plugin --profile web add ./dsh-plugins/ark-plan-api

Restart DSH after install, then open Settings → Models, pick an Ark provider and paste your API key. Each route reads its key from a separate env var (see table below); the Models UI writes the key to the correct name automatically.

安装后重启 DSH，打开 Settings → Models，选择 Ark provider 并粘贴 API Key。每条路由从独立的环境变量读取密钥（见下表），Models 设置页会自动写入对应变量。

Default wire protocol is the Anthropic Messages API. Base URLs intentionally omit the /v1 suffix — pi-ai hands baseURL straight to the Anthropic SDK, which appends /v1/messages.

默认走 Anthropic Messages 协议。baseURL 已省略 /v1 后缀，pi-ai 会将其直接传给 Anthropic SDK，由 SDK 拼接 /v1/messages。

Requirements / 前置条件

  • DSH ≥ 0.1.0
  • Node.js ≥ 22.19.0 (ships with DSH)
  • A Volcengine Ark API key with access to the corresponding endpoint
