Plug-in vision for text-only LLMs. ModLens converts an image into structured JSON evidence (OCR, layout, semantics) so a text-only model can "see". This fork keeps all upstream behavior and adds:

• provider argument on modlens_read_image — pin the vision engine per call (-p <provider> passthrough).
• "Ask which engine" behavior — the tool description instructs the model to ask the user which engine to use whenever more than one is configured.
• Doubao / Volcengine Ark recipe — a tested setup for doubao-seed-2.1-turbo via the Ark ark-coding-plan endpoint (OpenAI-compatible), alongside Gemini, Anthropic, and Claude Code.

Why a fork

Upstream ModLens is under active development. This fork carries the provider passthrough and the doubao/ark recipe until they land upstream. Prefer upstream for everything else: https://github.com/liustack/modlens.

Install (DeepSeek Harness)

dsh plugin --profile web add github:YZz-S/dsh-modlens

Restart dsh, then look for the (modlens vision) model entries and the modlens_read_image tool.

Configure engines

Config lives in ~/.modlens/config.json (shared with upstream modlens). Run modlens doctor to see what is ready.

Gemini (free, fast)

modlens config set gemini-api.apiKey <key>   # https://aistudio.google.com
modlens config set provider gemini-api

Doubao / Volcengine Ark (ark-coding-plan)

modlens config set openai.baseUrl https://ark.cn-beijing.volces.com/api/coding/v3
modlens config set openai.apiKey <ARK_CODING_PLAN_API_KEY>
modlens config set openai.model doubao-seed-2.1-turbo
# optional: modlens config set provider openai

Others

Claude Code (claude-cli), Anthropic (anthropic), Antigravity (antigravity-cli). Full recipes: skills/modlens/references/configure.md.

Per-call engine selection

When the model needs to read an image and more than one engine is configured, it asks you which to use, then calls modlens_read_image with the provider argument:

provider: "gemini-api" | "openai" (doubao/Ark) | "anthropic" | "claude-cli" | "antigravity-cli"

Omit provider to use the configured default and its failover chain.

Verify

modlens doctor          # local diagnostics, spends no quota
modlens -i image.png    # end-to-end read (spends one read)

English · ← 返回 DeepSeekHarnessPlugins

为纯文本 LLM 提供视觉能力。ModLens 把图片转换为结构化 JSON 证据（OCR、布局、语义），让纯文本模型也能"看见"。本分支保留全部上游行为，并新增：

• modlens_read_image 增加 provider 参数——每次调用可指定视觉引擎（-p <provider> 透传）。
• "询问使用哪个引擎"行为——工具描述指示模型在配置了多个引擎时，先询问用户要用哪个。
• 豆包 / 火山方舟 Ark 配方——经由 Ark ark-coding-plan 端点（OpenAI 兼容）使用 doubao-seed-2.1-turbo 的实测配置，与 Gemini、Anthropic、Claude Code 并列。

为什么做分支

上游 ModLens 正在积极开发中。本分支承载 provider 透传与豆包/Ark 配方，直到它们合入上游。其他一切请优先使用上游：https://github.com/liustack/modlens。

安装（DeepSeek Harness）

dsh plugin --profile web add github:YZz-S/dsh-modlens

重启 dsh，然后查找 (modlens vision) 模型条目与 modlens_read_image 工具。

配置引擎

配置位于 ~/.modlens/config.json（与上游 modlens 共用）。运行 modlens doctor 查看哪些已就绪。

Gemini（免费、快速）

modlens config set gemini-api.apiKey <key>   # https://aistudio.google.com
modlens config set provider gemini-api

豆包 / 火山方舟 Ark（ark-coding-plan）

modlens config set openai.baseUrl https://ark.cn-beijing.volces.com/api/coding/v3
modlens config set openai.apiKey <ARK_CODING_PLAN_API_KEY>
modlens config set openai.model doubao-seed-2.1-turbo
# 可选：modlens config set provider openai

其他

Claude Code（claude-cli）、Anthropic（anthropic）、Antigravity（antigravity-cli）。完整配方：skills/modlens/references/configure.md。

按调用选择引擎

当模型需要读取图片且配置了多个引擎时，它会先询问你使用哪个，然后带 provider 参数调用 modlens_read_image：

provider: "gemini-api" | "openai"（豆包/Ark）| "anthropic" | "claude-cli" | "antigravity-cli"

省略 provider 则使用配置的默认引擎及其故障转移链。

验证

modlens doctor          # 本地诊断，不消耗额度
modlens -i image.png    # 端到端读取（消耗一次读取）
