## Date
2026-02-08

## Task
Add top 10 OpenRouter models to TradingAgents CLI model selection

## Changes Made

### 1. Modified Files
- **cli/utils.py**: Added OpenRouter top 10 models to both shallow and deep thinking agent options
- **tests/test_cli_utils.py**: Created comprehensive test suite for CLI utilities

### 2. New Files
- **tests/__init__.py**: Package initialization
- **tests/test_cli_utils.py**: Test coverage for OpenRouter model configuration

### 3. Model Additions (Top 10 from OpenRouter.ai Rankings)
Added the following models to both SHALLOW_AGENT_OPTIONS and DEEP_AGENT_OPTIONS:

1. **Kimi K2.5 0127** (#1 ranked) - `moonshotai/kimi-k2.5-0127`
2. **Claude Opus 4.5** - `anthropic/claude-4.5-opus-20251124`
3. **Claude Sonnet 4.5** - `anthropic/claude-4.5-sonnet-20250929`
4. **Gemini 3 Flash Preview** - `google/gemini-3-flash-preview-20251217`
5. **Gemini 2.5 Flash** - `google/gemini-2.5-flash`
6. **Gemini 2.5 Flash Lite** - `google/gemini-2.5-flash-lite`
7. **Deepseek V3.2** - `deepseek/deepseek-v3.2-20251201`

9. **Grok Code Fast 1** - `x-ai/grok-code-fast-1`
10. **Minimax M2.1** - `minimax/minimax-m2.1`

Plus preserved existing free models:

- Z.AI GLM 4.5 Air (free) - `z-ai/glm-4.5-air:free`

### 4. Refactoring
- Moved `SHALLOW_AGENT_OPTIONS` and `DEEP_AGENT_OPTIONS` from function-local scope to module-level constants
- This enables better testability and reusability

### 5. Test Coverage
Created comprehensive tests covering:
- Model count verification (12+ models)
- Model format validation (provider/model structure)
- Top models inclusion check
- Free model preservation
- Duplicate detection
- Cross-list consistency
- All providers have model entries
