+Run Qwen Code with local OpenAI-compatible servers for offline development:
+
+```bash
+# For local OpenAI-compatible servers
+export OPENAI_API_KEY="any-value"  # Required but can be any non-empty value
+export OPENAI_BASE_URL="http://localhost:1234/v1"  # Your local server URL

+- Some local servers may have streaming reliability issues. Set `OPENAI_STREAMING=false` for improved stability

+# Automated test script for qwen-code LM Studio integration
+# 
+# Purpose: Build the fixed qwen-code, start it in byobu/tmux, and test LM Studio connectivity
+# Location: /Users/athundt/source/qwen-code/scripts/test-qwen-lmstudio-integration.sh
+# 
+# This script automates the complete process of:
+# 1. Building the fixed qwen-code version
+# 2. Using byobu/tmux to control qwen-code in window 2
+# 3. Testing the "test" command and capturing results
+# 4. Handling common stuck states with workarounds
