# 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 - For Nx plugin best practices, check `node_modules/@nx//PLUGIN.md`. Not all plugins have this file - proceed without it if unavailable. # CopilotKit AI agent framework with three layers: **Frontend** (React/Angular/Vanilla) → **Runtime** (Express/Hono) → **Agent** (LangGraph/CrewAI/BuiltIn/Custom), communicating via the AG-UI protocol (event-based SSE). ## Essentials - **Nx monorepo** — always run tasks through `nx` (`nx run`, `nx run-many`, `nx affected`), never the underlying tooling directly. - **Flat package structure** — all packages live directly under `packages/` (no `v1/` or `v2/` subdirectories). Every package uses the `@copilotkit/` scope. - **Simplicity** — prefer the simplest correct solution. For non-trivial changes, consider if there's a cleaner approach before committing. - **Worktrees** — always work in a git worktree for isolation. See [Git & PRs](.claude/docs/git.md) for the full workflow. - **Documentation lives in shell-docs** — author all CopilotKit docs in `showcase/shell-docs/src/content/`. The top-level `docs/` path is only a symlink to `showcase/shell-docs/`; never recreate the old `docs/content/docs/` tree. AG-UI protocol docs are authored upstream in `ag-ui-protocol/ag-ui`, not here. See [Documentation](.claude/docs/documentation.md). ## Reference (read when relevant to your task) - [Architecture & Packages](.claude/docs/architecture.md) — package roles, request lifecycle, core concepts (AG-UI, ProxiedAgent, AgentRunner, tools, context, multi-agent) - [Hook Development](.claude/docs/hooks.md) — checklist for creating new hooks (docs, tests, JSDoc) - [Workflow & Process](.claude/docs/workflow.md) — when to plan, when to fix autonomously, verification, self-improvement loop, this should be your default mindset when working on any task - [Git & PRs](.claude/docs/git.md) — worktree workflow, branching, creating PRs - [Documentation](.claude/docs/documentation.md) — where to author docs (CopilotKit → shell-docs; AG-UI → upstream); `docs/` is retired
