+# Plan: Custom AI Code Reviewer (GitHub Actions + OpenRouter)
+
+## Goal Description
+Implement AI Code Reviewer using **OpenRouter** (Mistral) instead of Gemini. Fix dependency conflicts and ensure compliance with OpenRouter API standards.
+
+## User Review Required
+> [!IMPORTANT]
+> **API Key**: Ensure `OPENROUTER_API_KEY` is set in GitHub Secrets.
+> **Model**: Using `mistralai/devstral-2512:free` as requested (Note: verification of exact model ID recommended).
+
+## Proposed Changes
+
+### Dependencies
+#### [MODIFY] [requirements.txt](file:///Users/nghialuutrung/Desktop/antigravity-kit/scripts/requirements.txt)
+*   Update `openai>=1.55.0` to resolve `httpx` proxy argument conflict.
+*   Keep `PyGithub`.
+
+### Logic Script
+#### [MODIFY] [ai_reviewer.py](file:///Users/nghialuutrung/Desktop/antigravity-kit/scripts/ai_reviewer.py)
+*   **Client Initialization**:
+    ```python
+    client = OpenAI(
+        base_url="https://openrouter.ai/api/v1",
+        api_key=api_key,
+        default_headers={
+            "HTTP-Referer": "https://github.com/hapo-nghialuu/antigravity-kit", # Attribution
+            "X-Title": "Antigravity AI Reviewer"
+        }
+    )
+    ```
+*   **Model**: Set `MODEL_NAME = "mistralai/devstral-2512:free"`.
+*   **JSON Handling**: Add robust try-catch for JSON parsing as free models might chatter.
+
+## Verification Plan
+
+### Manual Verification
+1.  **Re-run GitHub Action**: Trigger the workflow again on the existing PR.
+2.  **Check Logs**: Verify "OpenRouter response received" and no 404/401 errors.
