   - **Auto-Start & Discovery:** Automatically initializes configured servers on project load and dynamically aggregates their tools into the agent's capability declarations.
   - **Dedicated Operations UI:** Features a new **External Tools** section within the Operations Hub for monitoring server status (idle, starting, running, error) and browsing discovered tool schemas. Supports **Pop-Out Panel functionality**, allowing the External Tools interface to be detached into a standalone window for optimized multi-monitor workflows.
   - **Strict HITL Safety:** All external tool calls are intercepted and require explicit human-in-the-loop approval via the standard confirmation dialog before execution.
+- **Retrieval-Augmented Generation (RAG) Support:** Introduces advanced retrieval capabilities to overcome context window limitations and reduce hallucination.
+  - **Multi-Source Retrieval:** Supports local vector stores (ChromaDB) and an **External RAG Bridge** via the Model Context Protocol (MCP) for connecting to third-party retrieval services.
+  - **High-Performance Indexing:** Employs a parallelized indexing pipeline using `ThreadPoolExecutor` and incremental updates based on file `mtime` to handle large codebases efficiently.
+  - **Deep Discussion Integration:** Retrieved context fragments are automatically prepended to agent prompts and captured in the discussion history, featuring a dedicated visualization mode with source buttons for instant file navigation.
+  - **Configurable Strategy:** Users can toggle RAG globally and fine-tune retrieval parameters (source, embedding provider, chunk size/overlap) directly within the AI Settings.
+  - **Automated Synchronization:** Features background re-indexing of the project workspace, ensuring the vector store remains consistent with the current project state.
 - **High-Fidelity Selectable UI:** Most read-only labels and logs across the interface (including discussion history, comms payloads, tool outputs, and telemetry metrics) are now implemented as selectable text fields. This enables standard OS-level text selection and copying (Ctrl+C) while maintaining a high-density, non-editable aesthetic.
 - **High-Fidelity UI Rendering:** Employs advanced 3x font oversampling and sub-pixel positioning to ensure crisp, high-clarity text rendering across all resolutions, enhancing readability for dense logs and complex code fragments.
 - **Enhanced MMA Observability:** Worker streams and ticket previews now support direct text selection, allowing for easy extraction of specific logs or reasoning fragments during parallel execution.
