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

# OpenRouter/Custom API Fallback Behavior:
# When only OpenRouter or Custom API is configured (no native API keys), these
# model aliases automatically map to equivalent models through the proxy:
# - "flash" → "google/gemini-2.5-flash" (via OpenRouter)
# - "pro" → "google/gemini-2.5-pro" (via OpenRouter)
# - "o3" → "openai/o3" (via OpenRouter)
# - "o3mini" → "openai/o3-mini" (via OpenRouter)
# - "o4-mini" → "openai/o4-mini" (via OpenRouter)
# - "o4-mini-high" → "openai/o4-mini-high" (via OpenRouter)
#
# This ensures the same model names work regardless of which provider is configured.
# This architecture ensures:
# - No namespace collisions (models only appear when their provider is enabled)
# - API key-based filtering (prevents wrong models from being shown to Claude)
# - Proper provider routing (models route to the correct API endpoint)
# - Clean separation of concerns (providers own their model definitions)
# Temperature defaults for different tool types

### 6. Add Model Capabilities for Auto Mode
### 6. Add Model Descriptions for Auto Mode
Update `config.py` to add your models to `MODEL_CAPABILITIES_DESC`:
Add descriptions to your model configurations in the `SUPPORTED_MODELS` dictionary. These descriptions help Claude choose the best model for each task in auto mode:
```python
MODEL_CAPABILITIES_DESC = {
# ... existing models ...
# Example models - Available when EXAMPLE_API_KEY is configured
"large": "Example Large (100K context) - High capacity model for complex tasks",
"small": "Example Small (50K context) - Fast model for simple tasks",
# Full model names
"example-large-v1": "Example Large (100K context) - High capacity model",
"example-small-v1": "Example Small (50K context) - Fast lightweight model",
# In your provider implementation
SUPPORTED_MODELS = {
"example-large-v1": {
"context_window": 100_000,
"supports_extended_thinking": False,
"description": "Example Large (100K context) - High capacity model for complex tasks",
},
"example-small-v1": {
"context_window": 50_000,
"supports_extended_thinking": False,
"description": "Example Small (50K context) - Fast model for simple tasks",
},
# Aliases for convenience
"large": "example-large-v1",
"small": "example-small-v1",
}
```
The descriptions should be detailed and help Claude understand when to use each model. Include context about performance, capabilities, cost, and ideal use cases.
