 - **Manual "Vibe Coding" Assistant:** Serving as an auxiliary, multi-provider assistant that natively interacts with the codebase via sandboxed PowerShell scripts and MCP-like file tools, emphasizing manual developer oversight and explicit confirmation.
 
 ## Key Features
-- **Multi-Provider Integration:** Supports both Gemini and Anthropic with seamless switching.
+- **Multi-Provider Integration:** Supports Gemini, Anthropic, and DeepSeek with seamless switching.
 - **4-Tier Hierarchical Multi-Model Architecture:** Orchestrates an intelligent cascade of specialized models to isolate cognitive loads and minimize token burn.
   - **Tier 1 (Orchestrator):** Product alignment and high-level strategy using `gemini-3.1-pro-preview`.
   - **Tier 2 (Tech Lead):** Architectural design and technical planning using `gemini-3-flash-preview`.
-  - **Tier 3 (Worker):** Focused implementation and surgical code changes using `gemini-2.5-flash-lite`.
-  - **Tier 4 (QA):** Bug reproduction, test analysis, and error translation using `gemini-2.5-flash-lite`.

   - **MMA Delegation Engine:** Utilizes the `mma-exec` CLI and `mma.ps1` helper to route tasks, ensuring each tier receives role-scoped context (e.g., Orchestrators get Product docs; Workers get Workflow specs).
   - **Role-Scoped Documentation:** Automated mapping of foundational documents to specific tiers to prevent token bloat and maintain high-signal context.
 - **Strict Memory Siloing:** Employs AST-based interface extraction and "Context Amnesia" to provide workers only with the absolute minimum context required, preventing hallucination loops.
