CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

A single-file Express.js proxy (app.js) that translates Anthropic API (/v1/messages) requests to an Ollama API backend. It enables Claude SDK clients to route through this proxy to a local/remote Ollama instance at https://ollama.aquantico.de.

Running

node app.js

The proxy listens on port 11435. No build step, lint, or test infrastructure exists.

Key Architecture

• app.js — Single entry point. All logic is in one file.
• convertAnthropicToOllama() — Transforms Anthropic request body into Ollama format: maps system messages, converts content blocks (text + tool_results), sanitizes tool schemas, sets num_ctx: 131072 and think: false.
• handleResponse() — Reads Ollama's SSE stream and re-emits it as Anthropic-compatible SSE events (message_start, content_block_start, content_block_delta, content_block_stop, message_delta, message_stop).
• convertAnthropicTools() — Strips invalid fields from Anthropic tool schemas and normalizes them to Ollama's function-call format.
• Model names starting with claude- are silently replaced with qwen3.6:35b-a3b-q4_K_M.

Notable Details

• The proxy strips think from Ollama requests (hardcoded false).
• Tool call arguments are parsed and sent as a single partial_json delta.
• Request IDs use Date.now() for logging correlation.
• A backup of the previous version is saved as app.js.v10.
