name: nx description: Nx workspace commands and guidelines for running tasks, generators, and using Nx MCP tools

Nx

This is an Nx 22.5.3 monorepo using npm. Prefer the Nx MCP server over guessing about the workspace — it reflects the live project graph and config.

Use the MCP server first

  • nx_workspace — understand the project graph / architecture, and surface project-graph or config errors, before answering workspace questions.
  • nx_project_details — inspect a single project's targets and config.
  • nx_docs — fetch up-to-date Nx docs for any configuration/best-practice question instead of assuming.
  • nx_visualize_graph — show task/project dependencies.
  • nx_current_running_tasks_details / nx_current_running_task_output — inspect tasks already running in the user's terminals; rerun with nx run <taskId> so it executes in the same Nx context. Don't offer to rerun a continuous task.

Generators

When scaffolding, drive it through the MCP flow rather than hand-writing files: nx_generators to list, nx_generator_schema for options, then nx_open_generate_ui and read back nx_read_generator_log. Keep options minimal; use nx_available_plugins if no generator fits.

Commands

  • Run anything with nx run <project>[:target]; targets live in each project's project.json (or are inferred from config).
  • The canonical common commands (test / lint / typecheck / build / storybook) and the package↔lib mapping live in the Commands and Libraries sections of AGENTS.md — not duplicated here.
