Anthropic-to-OpenAI Proxy (v1.4.0)

This repository includes a **Node.js translation proxy** (`proxy/`) that lets Claude Code work with any local LLM through an OpenAI-compatible API. The proxy sits between Claude Code and the LLM backend, translating Anthropic Messages API requests into OpenAI Chat Completions format and back.

Quick Start

# One-time setup
cd proxy && npm install && cd ..

Option A — Claudio (VS Code extension)

Install the extension (`chat-extension/`) and open the repo in VS Code. The proxy starts automatically. The chat panel shows `● Connected` when ready. No separate terminal needed.

Option B — Claude Code CLI

sh start_agent_cli.sh
# Finds a free port, spawns the proxy, waits for health,
# lets you pick a model
