+    A[Discord Message] --> B[Message Filter]
+    B --> C[AI Model Selection]
+    C --> D[System Prompt Generation]
+    D --> E[AI Processing]
+    E --> F[Tool Execution]
+    F --> G[Response Generation]
+    G --> H[Discord Reply]
+
+    I[Built-in Tools] --> F
+    J[Custom Tools] --> F
+    K[AI Commands] --> F
+```
