This repo contains a Mastra weather agent/workflow wired into a Temporal worker.

Only the Mastra side:

• src/mastra/index.ts
• src/mastra/agents/weather-agent.ts
• src/mastra/tools/weather-tool.ts
• src/mastra/workflows/*

It does not cover the older AI SDK demo scripts under src/worker.ts / src/client.ts.

• Node.js 22+
• Temporal CLI installed
• An OpenAI API key

npm install
cp .env.example .env

Set your API key in .env:

OPENAI_API_KEY=your-api-key

Start a local Temporal server:

temporal server start-dev

In another terminal, start the Mastra Temporal worker:

npm run start:mastra

That runs src/mastra/workflows/worker.ts, which:

• connects to Temporal at localhost:7233
• registers the weather-workflow task queue
• loads workflow code from dist/mastra/temporal-workflow.js
• captures and registers generated activities

Build the TypeScript project:

npm run build

This compiles the project into dist/.

• src/mastra/index.ts — Mastra app entrypoint
• src/mastra/agents/weather-agent.ts — weather agent
• src/mastra/tools/weather-tool.ts — weather tool
• src/mastra/workflows/weather-workflow.ts — workflow definition
• src/mastra/workflows/worker.ts — Temporal worker bootstrap

• The Mastra agent uses openai/gpt-5-mini.
• The worker expects Temporal on localhost:7233.
• If you change workflow code, rebuild before restarting the worker so dist/mastra/temporal-workflow.js is up to date.
