Benjamin Taylor 501565c966 fix(examples): green parity + starter smoke — v2 label keys, llamaindex v2 state, parity sync
Addresses the blocking review on #5151:

1. Starter smoke 'Popup Assistant' timeouts (adk, agno, mastra,
   ms-agent-framework-python/dotnet): the pages passed the dead v1 label keys
   (labels.title / labels.initial), which v2 CopilotSidebar ignores — the
   header rendered the default 'CopilotKit Chat' so the smoke's
   text=Popup Assistant wait timed out. Map to the v2 CopilotChatLabels keys:
   title -> modalHeaderTitle, initial -> welcomeMessageText. Verified live:
   SSR now renders 'Popup Assistant'.

2. llamaindex TypeError (reading 'proverbs'): the page still used the v1
   useAgent API ({ state, setState } = useAgent({ name, initialState })) —
   v2 returns { agent }, so state was undefined at render. Migrate to the v2
   pattern (agent.state with a guarded default + agent.setState + one-time
   seed effect), and fix its dead v1 label keys too. Verified: next build
   prerenders all pages cleanly.

3. parity-check drift: ran _parity/sync.ts --all — syncs example-layout
   (mobile-header fix), layout.tsx, docker-route-override.ts to the
   north-star, and bumps @copilotkit/* to 1.59.1 in langgraph-fastapi and
   strands-python. parity verify: 0 errors across all instances.
   (next-env.d.ts is gitignored repo-wide; verify warns-and-skips it in a
   clean checkout, so it is intentionally not committed.)

4. Trailing-whitespace diff-check failure (showcase google-adk agent): already
   resolved by the merge of main (the file matches main; diff --check clean).

CopilotKit <> Microsoft Agent Framework Starter

This is a starter template for building AI agents using Microsoft Agent Framework and CopilotKit. It provides a modern Next.js application with an integrated proverbs management agent that demonstrates AG-UI protocol features including shared state, generative UI, and human-in-the-loop workflows.

Prerequisites

  • GitHub Personal Access Token (for GitHub Models API)

  • .NET 9.0 SDK

    • Download directly

    • macOS/Linux

      • Install via Homebrew (brew install dotnet@9) or

      • Install via curl install script
        curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --channel 9.0
        export PATH="$HOME/.dotnet:$PATH"
        
    • Windows

  • Node.js 20+

    • Download directly

    • macOS/Linux

      • Install via Homebrew (brew install node@24) or

      • Install via curl install script
        # Download and install nvm:
        curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash
        
        # in lieu of restarting the shell
        \. "$HOME/.nvm/nvm.sh"
        
        # Download and install Node.js:
        nvm install 24
        
    • Windows

  • Any of the following package managers:

Getting Started

  1. Install dependencies using your preferred package manager:

    # Using npm (default)
    npm install
    
    # Using pnpm
    pnpm install
    
    # Using yarn
    yarn install
    
    # Using bun
    bun install
    

    Note: This will automatically setup the C# agent as well (restore NuGet packages).

    If you have manual issues, you can run:

    npm run install:agent
    
  2. Set up your GitHub token for GitHub Models:

    First, get your GitHub token:

    gh auth token
    

    Then, navigate to the agent directory and set it as a user secret:

    cd agent
    dotnet user-secrets set GitHubToken "<your-token>"
    cd ..
    

    Or set it in one command:

    cd agent; dotnet user-secrets set GitHubToken "$(gh auth token)"; cd ..
    
  3. Start the development server:

    # Using npm (default)
    npm run dev
    
    # Using pnpm
    pnpm dev
    
    # Using yarn
    yarn dev
    
    # Using bun
    bun run dev
    

    This will start both the Next.js UI (port 3000) and C# agent server (port 8000) concurrently.

Available Scripts

The following scripts can also be run using your preferred package manager:

  • dev - Starts both UI and agent servers in development mode
  • dev:debug - Starts development servers with debug logging enabled
  • dev:ui - Starts only the Next.js UI server
  • dev:agent - Starts only the C# agent server
  • build - Builds the Next.js application for production
  • start - Starts the production server
  • lint - Runs ESLint for code linting
  • install:agent - Restores NuGet packages for the C# agent

Features Demonstrated

This starter showcases key AG-UI protocol features:

  • 🔄 Shared State: Proverbs list synchronized between frontend and agent
  • 🎨 Generative UI: Weather card rendered from backend tool
  • 👤 Human-in-the-Loop: Moon card with approval workflow
  • 🛠️ Frontend Actions: Theme color changes from agent
  • 💬 Agentic Chat: Natural language interface with tool calling

Troubleshooting

Agent Connection Issues

If you see "I'm having trouble connecting to my tools", make sure:

  1. The C# agent is running on port 8000
  2. Your GitHub token is set correctly via user secrets
  3. Both servers started successfully (check terminal output)

.NET SDK Not Installed

If you don't have .NET 9.0 installed:

macOS/Linux (Homebrew):

brew install dotnet@9
dotnet --version

macOS/Linux (Install Script):

curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --channel 9.0
export PATH="$HOME/.dotnet:$PATH"

Windows (WinGet):

winget install --id=Microsoft.DotNet.SDK.9 -e

Windows/macOS (Direct Download):

.NET SDK Issues

If you encounter .NET-related errors:

# Verify .NET SDK is installed
dotnet --version  # Should be 9.0.x or higher

# Restore packages manually
cd agent
dotnet restore
dotnet run

GitHub Token Issues

If the agent fails to start with "GitHubToken not found":

cd agent
dotnet user-secrets set GitHubToken "$(gh auth token)"

Or manually:

# Get your token
gh auth token

# Set it as a user secret
cd agent
dotnet user-secrets set GitHubToken "YOUR_TOKEN_HERE"

Port Conflicts

If port 8000 is already in use, you can change it in:

  • agent/Properties/launchSettings.json - Update applicationUrl
  • src/app/api/copilotkit/route.ts - Update the HttpAgent URL
