"""
Integration tests to ensure normal prompt handling works with real API calls.

This test module verifies that all tools continue to work correctly with
normal-sized prompts using real integration testing instead of mocks.

INTEGRATION TESTS:
These tests are marked with @pytest.mark.integration and make real API calls.
They use the local-llama model which is FREE and runs locally via Ollama.

Prerequisites:
- Ollama installed and running locally
- CUSTOM_API_URL environment variable set to your Ollama endpoint (e.g., http://localhost:11434)
- local-llama model available through custom provider configuration
- No API keys required - completely FREE to run unlimited times!

Running Tests:
- All tests (including integration): pytest tests/test_prompt_regression.py
- Unit tests only: pytest tests/test_prompt_regression.py -m "not integration"
- Integration tests only: pytest tests/test_prompt_regression.py -m "integration"

Note: Integration tests skip gracefully if CUSTOM_API_URL is not set.
They are excluded from CI/CD but run by default locally when Ollama is configured.
