Openclaude Multi Llm

# OpenClaude Multi-LLM Skill

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

OpenClaude is a fork of Claude Code that routes all LLM calls through an OpenAI-compatible shim (`openaiShim.ts`), letting you use any model that speaks the OpenAI Chat Completions API — GPT-4o, DeepSeek, Gemini via OpenRouter, Ollama, Groq, Mistral, Azure, and more — while keeping every Claude Code tool intact (Bash, FileRead, FileWrite, FileEdit, Glob, Grep, WebFetch, Agent, MCP, Tasks, LSP, NotebookEdit).

## Installation

### npm (recommended)

```bash
npm install -g @gitlawb/openclaude
# CLI command installed: openclaude
```

### From source (requires Bun)

```bash
git clone https://node.gitlawb.com/z6MkqDnb7Siv3Cwj7pGJq4T5EsUisECqR8KpnDLwcaZq5TPr/openclaude.git
cd openclaude
bun install
bun run build
# optionally link globally
npm link
```

### Run without build

```bash
bun run dev       # run directly with Bun, no build step
```

## Activation — Required Environment Variables

You must set `CLAUDE_CODE_USE_OPENAI=1` to enable the shim. Without it, the tool falls back to the Anthropic SDK.

| Variable | Required | Purpose |
|---|---|---|
| `CLAUDE_CODE_USE_OPENAI` | Yes | Set to `1` to activate OpenAI provider |
| `OPENAI_API_KEY` | Yes* | API key (*omit for local Ollama/LM Studio) |
| `OPENAI_MODEL` | Yes | Model identifier |
| `OPENAI_BASE_URL` | No | Custom endpoint (default: `https://api.openai.com/v1`) |
| `CODEX_API_KEY` | Codex only | ChatGPT/Codex access token |
| `CODEX_AUTH_JSON_PATH` | Codex only | Path to Codex CLI `auth.json` |

`OPENAI_MODEL` takes priority over `ANTHROPIC_MODEL` if both are set.
