 # Copilot Instructions — McpServerManager (RequestTracker)
 
-## ⚠️ PRIORITY ORDER — NON-NEGOTIABLE ⚠️
-
-**Speed is never more important than following workspace procedures.**
-
-Before doing ANY work on ANY user request, you MUST complete these steps in order:
-
-3. **POST `/mcpserver/sessionlog`** with your session entry — do NOT proceed until this succeeds
-4. **GET `/mcpserver/sessionlog?limit=5`** to review recent session history for context
-5. **GET `/mcpserver/todo`** to check current tasks
-6. **THEN** begin working on the user's request
-
-On EVERY subsequent user message:
-1. POST an updated session log entry BEFORE starting work
-2. Complete the user's request
-3. POST the final session log with results, actions taken, and files modified
-
-**If you skip any of these steps, STOP and go back and do them before continuing.**
-Session logging is not optional, not deferred, and not secondary to the task.
+See `AGENTS-README-FIRST.yaml` in the workspace root for MCP server connection details, session logging procedures, and agent conduct guidelines.
