Demonstrates agent summarization with a short trigger window so you can see summaries created during a single run.

• Node.js (v20 or newer)
• OpenAI API key (with access to openai/gpt-5.1)

1. Install dependencies:

   pnpm install

2. Create your environment file:

   cp .env.example .env

3. Add your API key to .env:

   OPENAI_API_KEY=your-api-key

4. Run the example:

   pnpm dev

If you do not have access to openai/gpt-5.1, change the model in src/index.ts to openai/gpt-4o-mini (or another available model) and remove the OpenAI reasoning options.

• Creates a single Agent with summarization enabled.
• Enables OpenAI native reasoning by using openai/gpt-5.1 with providerOptions.openai.reasoningEffort.
• Uses a low triggerTokens value so summaries are created quickly.
• Starts a VoltAgent server so you can chat with the agent over HTTP.
