copilotkit

name	copilotkit
description	CopilotKit v2 hub — operator chat runtime, AG-UI/SSE streaming, A2UI surfaces, Mastra/LangGraph integrations, setup, develop, debug, upgrade, OSS contribute. Use whenever the user touches CopilotKit, CopilotChat/CopilotSidebar/Popup, /api/copilotkit (including 401 on /info), useAgent/useFrontendTool/useHumanInTheLoop, agent not found / agentId mismatch, frontend tools not executing, SSE stuck after RunStarted, AG-UI, A2UI createSurface, license token / publicLicenseKey, v1→v2 migration, or wiring Mastra agents in app/ — even if they never say "CopilotKit". Load references/ on demand. iPix prod: references/ipix-production.md; debug: references/debug/debug.md. Do NOT use for Supabase-only migrations/RLS, Mercur checkout, shadcn-only UI tweaks, Gemini edge prompts, or Linear issue updates without CopilotKit code.

CopilotKit Skills Hub

One consolidated CopilotKit plugin skill. Load the matching references/ file on demand — do not paste reference bodies here. Each topic folder keeps its own references/ sub-docs and assets/.

Consolidation (v2.1.0): former standalone skills copilotkit-setup, copilotkit-develop, copilotkit-integrations, copilotkit-agui, copilotkit-debug, copilotkit-upgrade, copilotkit-self-update, copilotkit-contribute, a2ui-renderer, runtime, and react-core are now references/ inside this skill. Behavior preserved; packaging only.

Routing decision tree

CopilotKit task
  ├─ iPix prod / Vercel / license / 401?           → references/ipix-production.md
  ├─ New project / first integration?              → references/setup/setup.md
  ├─ Chat UI, frontend tools, context, interrupts? → references/develop/develop.md
  ├─ External agent framework (Mastra, LangGraph…)?  → references/integrations/integrations.md
  │     (+ references/runtime/runtime.md for deep server wiring)
  ├─ Custom backend / AG-UI events / SSE?          → references/agui/agui.md
  ├─ Agent emits A2UI createSurface/updateComponents? → references/a2ui-renderer.md
  ├─ Something broken (stream, tools, connectivity)?  → references/debug/debug.md
  ├─ Upgrading from v1?                            → references/upgrade/upgrade.md
  ├─ Stale CopilotKit skill knowledge?             → references/self-update.md
  ├─ PR to CopilotKit/CopilotKit?                  → references/contribute/contribute.md
  ├─ Deep @copilotkit/runtime API?                 → references/runtime/runtime.md
  └─ Deep @copilotkit/react-core hooks?             → references/react-core/react-core.md

iPix Operator Hub path: setup → integrations (Mastra) → develop → a2ui-renderer as needed.

Live documentation (MCP)

This plugin bundles the copilotkit-docs MCP server (search-docs, search-code) for live CopilotKit docs and source lookups. See .mcp.json.

• Cursor / Claude Code: MCP auto-configured when the plugin is installed.
• Codex / manual: see references/debug/debug.md#mcp-setup.

Use MCP alongside references when API signatures may have changed since the bundled docs were synced.

How to use this skill

1. Identify the task from the routing table or decision tree above.
2. Load only that topic's entry guide (references/<topic>/...).
3. Load deeper sub-references on demand when the guide points to them — keep context lean.
4. For framework wiring, also load references/runtime/runtime.md when server-side detail is needed.
