 ## Important: Assertion Pattern
 
-Ollama returns a raw JSON **string** — assertions must parse it inline:
+Ollama returns a raw JSON **string** — assertions must be single **expressions** (no `const`/`return` blocks):
 
 ```yaml
-# ✅ Correct — parse the string first
+# ✅ Correct — single expression with function(e){return ...}
+- type: javascript
+  value: "JSON.parse(output).extractions.map(function(e){return e.extraction_class}).includes('action')"
+
+# ❌ Wrong — statement block causes SyntaxError: Unexpected token 'return'
 - type: javascript
   value: "const r=JSON.parse(output); return r.extractions.map(e=>e.extraction_class).includes('action');"
+```
 
-# ❌ Wrong — output is a string, not an object
-- type: javascript
-  value: output.classes.includes('action')
+### DeepSeek R1 — Strip `<think>` blocks
+
+R1 models emit reasoning traces before JSON. Add a provider-level transform:
+
+```yaml
+providers:
+  - id: openai:chat:deepseek-r1:32b
+    config:
+      apiBaseUrl: http://localhost:11434/v1
+      apiKey: ollama
+      transform: "output.replace(/<think>[\\s\\S]*?<\/think>/g, '').trim()"
 ```

+**Key takeaway:** Cloud models are 5–6x faster per request due to massive parallel GPU infrastructure. Local wins on cost, privacy, and no proxy/quota issues.
