Introduction

DeepSeek Harness (DSH) allows extension through plugins. Traditional integration with Codex and Antigravity (Gemini) usually requires starting a local proxy service to listen on a port. dsh-cliproxyapi solves this by building on CLIProxyAPI and natively integrating protocol bridging logic inside Harness, so the subscription interfaces of both platforms can be used without deploying additional background processes.

Plugin Positioning

This is a DSH plugin maintained by new-Beginner and categorized under “Network Tools”. It aims to provide DSH users with a local-proxy-free option to invoke Codex and Antigravity services directly inside Harness.

Core Features

  1. Natively embedded protocol bridging: Directly connects to Codex (OpenAI OAuth) and Antigravity (Google OAuth) subscription interfaces inside Harness, without local port listening.
  2. Modern settings panel: Provides a native-style “Subscription Account” management interface, supporting account connection, model list viewing, quota overview, thinking intensity tuning, multimodal vision toggle, and proxy configuration.
  3. Smart quota display and memory:
    - Displays quota rings in the status bar and session input box.
    - Supports adaptive layout for 5-hour and weekly quotas.
    - Smartly remembers the reasoning/thinking level for each model.
  4. Tool calling and multimodal compatibility: Seamlessly supports converting complex JSON Schema (union types, constrained fields, etc.) into Gemini’s strict subset, ensuring subagents and complex tool workflows run without friction.
  5. Image generation and editing: Integrates the cpa_image_generate tool, connects with Harness’s attachment system, and supports image-to-image generation, reference image editing, and high-resolution preview.

Installation and Enablement

Use the following command to install the plugin in Web profile mode:

dsh plugin --profile web add ./dsh-cliproxyapi-2.3.5.tgz

After installation, restart DeepSeek Harness to apply the changes.

Typical Usage

  1. Go to Settings → Subscription Accounts in Harness.
  2. In the Codex or Antigravity card, click “Log in to account” and complete login through browser authorization.
  3. Enable the models you want to use in “Model Settings” (such as gpt-5.4, gemini-3.8-flash, etc.).
  4. Create a new session and switch to the corresponding subscription model in the model selector to start using it.
