+"""Integration tests for HermesAgentLoop tool calling.
+
+Tests the full agent loop with real LLM calls via OpenRouter.
+Uses stepfun/step-3.5-flash:free by default (zero cost), falls back
+to anthropic/claude-sonnet-4 if the free model is unavailable.
+
+These tests verify:
+1. Single tool call: model calls a tool, gets result, responds
+2. Multi-tool call: model calls multiple tools in one turn
+3. Multi-turn: model calls tools across multiple turns
+4. Unknown tool rejection: model calling a non-existent tool gets an error
+5. Max turns: loop stops when max_turns is reached
+6. No tools: model responds without calling any tools
+7. Tool error handling: tool execution errors are captured
+
+Run:
+    pytest tests/test_agent_loop_tool_calling.py -v
