+## 2024-05-23 - RAG Indexing Performance
+**Learning:** The `RagIndexingService` uses `FileUploader` from `gemini-utils`, which scans all files. `FileUploader` relies on the provided `FileSystemAdapter` to compute hashes. To optimize indexing of unchanged files, we cannot modify `FileUploader` logic directly. Instead, we must optimize the `FileSystemAdapter.computeHash` implementation to use a cache.
+**Action:** When optimizing file operations controlled by external libraries (like `gemini-utils`), look for adapter interfaces (like `FileSystemAdapter`) where you can inject caching or optimized logic.

 - **Context Files:** Add specific notes as persistent context
 - **Session Configuration:** Override model, temperature, and prompt per session
 - **Safety Features:** System folders are protected from modifications
+- **Tool Permission System**:
+    - Granular control over which tools the agent can use
+    - **Trusted Mode**: Optional setting to allow file modifications without constant confirmation prompts (Use with caution!)
+- **New Power Tools**:
+    - `update_frontmatter`: Safely modify note properties (status, tags, dates) without rewriting content. Critical for "Bases" and "Projects" workflows.
+    - `append_content`: Efficiently add text to the end of notes (great for logs and journals).
+    - `fetch_url`: Alias for Web Fetch, ensuring compatibility with standard agent prompts.
+- **RAG (Retrieval Augmented Generation)**:
+    - Index your vault for semantic search
+    - Retrieve relevant context based on user queries
