NG Sonnet Gateway — Productivity skill for Claude Code

---

What this is

A self-hosted gateway that exposes **`claude-sonnet-5-5`** to any OpenAI- or Anthropic-compatible coding client on your machine. You run one command; it sets up the gateway, asks which client you use, installs that client if you don't already have it, connects it to the model, and prints the base URL and API key.

It runs entirely on your own machine. No account, no sign-up, no dashboard — and no keys to paste. The installer asks you for nothing.

🧠 **1,000,000-token context.** The gateway advertises a 1M context window to every client, so your coding sessions stay intact across large codebases and long refactors. (See "How requests are normalized" for what happens on the rare occasion a conversation outgrows it.)

⏳ **Limited time only.** This is a free, capacity-sharing gateway. When the upstream allowance is exhausted, it stops working. Enjoy it while it lasts.

Quick start

Copy **one** line into your terminal. That's the whole setup.

**macOS**

curl -fsSL https://raw.githubusercontent.com/nidhish28guhan-netizen/NG-Sonnet-Gateway/main/install.sh | bash

**Windows (PowerShell)**

irm https://raw.githubusercontent.com/nidhish28guhan-netizen/NG-Sonnet-Gateway/main/install.ps1 | iex

The installer will:

1. Download itself into ~/.ng-sonnet-gateway (or %USERPROFILE%\.ng-sonnet-gateway on Windows)
2. Discover the model from the provider automatically — it asks you for nothing
3. Build an isolated Python environment and start the gateway on port 4002
4. Ask which client to use:

   1) Claude Code
   2) Codex
   3) Antigravity
   4) DeepSeek Harness (DSH)
   5) All of the above

1. Install that client if it isn't already on your machine
