+Validation test for Harmony Provider GPT-OSS Tool-Calling Fix
+
+This script validates that the Harmony provider correctly strips the `strict` 
+parameter from tool definitions before sending to vLLM, enabling tool calling 
+to work with gpt-oss-20b and gpt-oss-120b models.
+
+Usage:
+    python3 test_harmony_toolcall_fix.py
+    
+Requirements:
+    - Roo Code with updated harmony.ts provider
+    - vLLM 0.10.2 running at http://localhost:5000
+    - gpt-oss-20b model loaded
