 ### 1. `validate_model()` is never called
 - Add validation call in `get_llm()` with warning (not error) for unknown models
 
-### 2. Inconsistent parameter handling
+### 2. ~~Inconsistent parameter handling~~ (Fixed)
-| Client | API Key Param | Special Params |
+- GoogleClient now accepts unified `api_key` and maps it to `google_api_key`
-|--------|---------------|----------------|
-| OpenAI | `api_key` | `reasoning_effort` |
-| Anthropic | `api_key` | `thinking_config` → `thinking` |
-| Google | `google_api_key` | `thinking_budget` |
 
-**Fix:** Standardize with unified `api_key` that maps to provider-specific keys
+### 3. ~~`base_url` accepted but ignored~~ (Fixed)
+- All clients now pass `base_url` to their respective LLM constructors
 
-### 3. `base_url` accepted but ignored
+### 4. ~~Update validators.py with models from CLI~~ (Fixed)
-- `AnthropicClient`: accepts `base_url` but never uses it
+- Synced in v0.2.2
-- `GoogleClient`: accepts `base_url` but never uses it (correct - Google doesn't support it)
-
-**Fix:** Remove unused `base_url` from clients that don't support it
-
-### 4. Update validators.py with models from CLI
-- Sync `VALID_MODELS` dict with CLI model options after Feature 2 is complete
