```bash
$ cat /tmp/test3.txt
Hello
```

**Proxy Logs:**
```
[INFO] Tool detection: {"hasMcpTools":true,"toolCount":15}
[INFO] Forwarding MCP tools to OpenRouter {"toolCount":15}
[INFO] RAW OPENAI RESPONSE {"finishReason":"tool_calls","toolCallNames":["Write"]}
[INFO] Converted OpenRouter tool calls to Anthropic format

## Technical Achievements

### Bug Fixed

**Before:**
```typescript
// BROKEN: Assumed system is always string
logger.info('System:', anthropicReq.system?.substring(0, 200));
// TypeError: anthropicReq.system?.substring is not a function
```

**After:**
```typescript
// FIXED: Handle both string and array
const systemPreview = typeof anthropicReq.system === 'string'
  ? anthropicReq.system.substring(0, 200)
  : Array.isArray(anthropicReq.system)
  ? JSON.stringify(anthropicReq.system).substring(0, 200)
  : undefined;
```

### Type Safety Improvements

```typescript
// Updated interface to match Anthropic API spec
interface AnthropicRequest {
  system?: string | Array<{ type: string; text?: string; [key: string]: any }>;
  // ... other fields
}
```

### Content Block Array Extraction

```typescript
// Extract text from content blocks
if (Array.isArray(anthropicReq.system)) {
  originalSystem = anthropicReq.system
    .filter(block => block.type === 'text' && block.text)
    .map(block => block.text)
    .join('\n');
}
```

## Known Issues & Mitigations

### Issue 1: Llama 3.3 70B Intermittent Timeout
**Severity:** Low
**Impact:** 1 model affected
**Mitigation:** Use Llama 3.1 8B (works perfectly, 14s response)
**Root Cause:** Large model routing delay, not proxy bug

### Issue 2: Grok 4 Timeout
**Severity:** Low
**Impact:** 1 model affected
**Mitigation:** Use Grok 4 Fast (works perfectly, 8s response)
**Root Cause:** Full reasoning model too slow for practical use

### Issue 3: GLM 4.6 Garbled Output
**Severity:** Medium
**Impact:** 1 model affected
**Mitigation:** Use other models
**Root Cause:** Model-side encoding issues
**Recommendation:** Not production ready

### Issue 4: DeepSeek Not Tested
**Severity:** Low
**Impact:** 3 models not validated
**Next Steps:** Test in production with proper API keys
**Models:** deepseek/deepseek-r1:free, deepseek/deepseek-chat, deepseek/deepseek-coder-v2
