# 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>/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 under `packages/` with the `@copilotkit/` scope. Some packages have `v1/` and `v2/` internal directories for backward compatibility, but they're a single published package.
|
|
- **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.
|
|
- **Commit as you go** — every meaningful unit of work gets its own commit, pushed immediately. Don't let untracked files accumulate across a session. Tests belong in the commit that introduces the code being tested. Full rules in [Git & PRs](.claude/docs/git.md#commit-early-and-often-in-logical-chunks).
|
|
- **Draft PR up front** — the moment a new branch has one commit, push it and open a **draft PR**. Don't wait until "ready" — unmerged-and-unpushed work is invisible. Flip the PR from draft to ready (`gh pr ready <pr#>`) only when the developer says so. See [Git & PRs](.claude/docs/git.md#open-a-draft-pr-up-front).
|
|
- **Documentation lives in shell-docs** — author 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 for live documentation. AG-UI protocol docs are authored upstream in `ag-ui-protocol/ag-ui`, not directly in this repo. See [Documentation](.claude/docs/documentation.md).
|
|
|
|
## Private Agent Instructions
|
|
|
|
Individual developers may optionally create a `private-agents.md` file at the repo root. This file is gitignored and not shared with the team -- it contains personal agent instructions, workflow overrides, or context that applies only to that developer's work. If `private-agents.md` exists, read it and follow its instructions (they take precedence over the defaults in this file where they conflict).
|
|
|
|
## Internal Skills
|
|
|
|
The team maintains shared AI agent skills at [CopilotKit/internal-skills](https://github.com/CopilotKit/internal-skills). If installed as a Claude Code plugin, these skills are available automatically. Key skills relevant to this repo:
|
|
|
|
- **copilotkit-ui-theme** — CopilotCloud visual design system (colors, typography, glass effects, blur circles). Use when building any UI that should look like an official CopilotKit product.
|
|
- **copilotkit-branding** — Brand rules, logos, and visual identity guidelines.
|
|
- **copilotkit-dev-workflow** — Internal dev workflow conventions for this monorepo.
|
|
- **cr-loop** — Automated code review and fix loop.
|
|
|
|
If you need a skill and don't have the plugin installed, clone the repo and read the relevant `skills/<name>/SKILL.md` directly.

## Documentation Editing
|
|
|
|
Before editing anything that looks like product docs, read [Documentation](.claude/docs/documentation.md) and the local README for the docs area you are touching. The live docs source is **`showcase/shell-docs/`**; top-level `docs/` is only a symlink there.
|
|
|
|
- **CopilotKit product docs** live under `showcase/shell-docs/src/content/`:
|
|
- Guides, how-tos, and concepts: `showcase/shell-docs/src/content/docs/`
|
|
- API reference: `showcase/shell-docs/src/content/reference/`
|
|
- Shared MDX snippets: `showcase/shell-docs/src/content/snippets/`
|
|
- Framework overview pages: `showcase/shell-docs/src/content/framework-overviews/`
|
|
- When adding or moving a guide page under `showcase/shell-docs/src/content/docs/`, update that section's `meta.json` so the page appears in navigation.
|
|
- The v2 API reference under `showcase/shell-docs/src/content/reference/{components,hooks,sdk}/` does **not** use `meta.json`; navigation is generated from page frontmatter. Only `reference/v1/` uses `meta.json`.
|
|
- For framework docs, check the framework's `docs_mode` in `showcase/integrations/<slug>/manifest.yaml` and confirm the docs folder with `getDocsFolder()` in `showcase/shell-docs/src/lib/registry.ts`.
|
|
- For showcase-driven frameworks (`docs_mode: generated`), update the showcase source of truth: manifests, demos, feature coverage, source regions, registry inputs, shared/root MDX, and sparse framework overrides. Do not hand-edit generated files under `showcase/shell-docs/src/data/frameworks/`.
|
|
- For authored frameworks (`docs_mode: authored`), edit `showcase/shell-docs/src/content/docs/integrations/<docsFolder>/` and its `meta.json`.
|
|
- For snippets, edit `showcase/shell-docs/src/content/snippets/`; snippets can feed root docs, authored framework pages, and showcase-driven framework pages.
|
|
- **AG-UI protocol docs** are canonical upstream in `ag-ui-protocol/ag-ui`. The `showcase/shell-docs/src/content/ag-ui/` tree is a downstream mirror; change AG-UI upstream first, then sync the mirror back.
|
|
- **Do not recreate `docs/content/docs/`**. Top-level `docs/` is only a symlink to shell-docs. The retired Next app no longer publishes to `docs.copilotkit.ai`. Historical content is available from the archive branch/tag, not from `main`.
|
|
- To run shell-docs locally, follow `showcase/shell-docs/README.md` and use the shell-docs npm commands.
