+# General Guidelines for working with Nx
+
+- When running tasks (for example build, lint, test, e2e, etc.), always prefer running the task through `nx` (i.e. `nx run`, `nx run-many`, `nx affected`) instead of using the underlying tooling directly
+- You have access to the Nx MCP server and its tools, use them to help the user
+- When answering questions about the repository, use the `nx_workspace` tool first to gain an understanding of the workspace architecture where applicable.
+- When working in individual projects, use the `nx_project_details` mcp tool to analyze and understand the specific project structure and dependencies
+- For questions around nx configuration, best practices or if you're unsure, use the `nx_docs` tool to get relevant, up-to-date docs. Always use this instead of assuming things about nx configuration
+- If the user needs help with an Nx configuration or project graph error, use the `nx_workspace` tool to get any errors
