Independent use will determine whether Lupin can run Claude Code’s existing MCP, skills, and workflow configuration across OpenAI, Gemini, local, and other model backends without material compatibility failures.

What is this?

Lupin is presented as a newly created tool or repository that aims to run the Claude Code harness—including MCP servers, skills, and Markdown-based workflow configuration—against OpenAI, Gemini, DeepSeek, Kimi, local models, and other backends. The supplied material does not identify its creator or independently demonstrate successful cross-model operation; the surrounding snippets show that API-format mismatches and backend-specific capabilities can cause compatibility failures. Its central portability claim therefore remains a hypothesis requiring independent testing, and the snippets do not establish that Lupin uses LiteLLM or any particular translation layer.

Why it matters to Scott

Scott already holds and implements this position in Ask terminal agent, Markdown OS, and Model-Plus-Harness Benchmark Unit: preserve an inspectable harness while swapping models, then evaluate the model-plus-harness combination rather than assuming API compatibility. Lupin is nevertheless worth testing as a direct benchmark or alternative to Ask’s LiteLLM and multi-format compatibility layer, especially for whether Claude-specific tool calls, skills, MCP configuration, and reasoning state survive backend changes.

🟠 redditI built Lupin so you can run Claude Code on GPT 5.6 Sol Kimi K3, DeepSeek Flash, or a local model without touching Claude Code harness setup (MCP, skills, .md files etc)
