Fix for: https://github.com/BeehiveInnovations/zen-mcp-server/issues/102 - Removed centralized MODEL_CAPABILITIES_DESC from config.py - Added model descriptions to individual provider SUPPORTED_MODELS - Updated _get_available_models() to use ModelProviderRegistry for API key filtering - Added comprehensive test suite validating bug reproduction and fix

Test to reproduce and fix the OpenRouter model name resolution bug.
|
|
|
|
This test specifically targets the bug where:
|
|
1. User specifies "gemini" in consensus tool
|
|
2. System incorrectly resolves to "gemini-2.5-pro" instead of "google/gemini-2.5-pro"
|
|
3. OpenRouter API returns "gemini-2.5-pro is not a valid model ID"
