SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies the complex migration from CopilotKit v1 to v2 by providing a structured path to update package imports, replace deprecated hooks, and transition to the AG-UI protocol.

Core Features & Use Cases

  • API Mapping: Automatically identifies deprecated v1 hooks like useCopilotAction and provides the v2 equivalent, useFrontendTool.
  • Protocol Transition: Guides the shift from GraphQL-based runtimes to the new AG-UI SSE-based protocol.
  • Dependency Management: Provides a clear roadmap for consolidating fragmented React packages into the unified @copilotkit/react package.

Quick Start

Use the copilotkit-upgrade skill to audit my current codebase and generate a migration plan for moving from v1 to v2.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I migrate CopilotKit v1 to v2?▼

Migrating CopilotKit v1 to v2 requires refactoring codebases to replace deprecated hooks like useCopilotAction with useFrontendTool, consolidating fragmented React packages into @copilotkit/react, and transitioning runtimes to the AG-UI streaming protocol.

What is the AG-UI protocol in CopilotKit v2?▼

The AG-UI protocol is a modern streaming event-based communication architecture that replaces the legacy GraphQL-based runtimes in CopilotKit v1, utilizing SSE-based communication to maintain agentic functionality.

How do I replace deprecated CopilotKit v1 hooks?▼

To replace deprecated CopilotKit v1 hooks, map legacy APIs such as useCopilotAction to their v2 equivalents like useFrontendTool, ensuring that agentic functionality is preserved during the refactoring process.

Can I consolidate CopilotKit React packages during v2 migration?▼

Consolidating CopilotKit React packages during v2 migration involves transitioning fragmented v1 dependencies into the unified @copilotkit/react package, streamlining dependency management while adopting the AG-UI protocol architecture.

Does CopilotKit v2 support GraphQL runtimes?▼

CopilotKit v2 does not use GraphQL-based runtimes; it transitions to the new AG-UI SSE-based protocol for streaming event-based communication, requiring endpoint reconfiguration during the v1 to v2 migration.

What are the limitations of migrating CopilotKit v1 to v2?▼

Migrating CopilotKit v1 to v2 requires comprehensive endpoint reconfiguration and hook replacement, meaning agentic functionality may be disrupted if the streaming event-based communication architecture is not fully adopted.
