Hot Demos

Runnable tutorial projects for Hot.

Each directory is a standalone Hot project with its own hot.hot, README, .env.example, source, and tests. You can clone one demo without cloning the others.

Demos

Project	What it is
hot-chat	Start here. Next.js chat UI plus TeamAgent and PersonalAgent in one hot dev
slack-bot	multi-provider AI Slack bot (Claude / GPT / Grok / Gemini), polling-in-dev / webhooks-in-prod
my-news	scheduled job that summarizes AI news with Claude and emails via Resend
graph-rag-memory	graph-RAG memory primitives and hybrid retrieval (function-driven)

The Hot Chat walkthrough lives in the main Hot docs at /docs/demos/hot-chat. The Agent Graph conventions are also worth a quick read before you wire up a new agent.

Run A Demo

cd hot-chat
hot dev --open

Run tests:

hot test

Context Variables

Some demos include hot/ctx.hot as a local-development convenience for bridging values from .env into Hot context variables. Hot Dev Cloud ignores hot/ctx.hot; for deployed demos, add the same context variables in the Hot Dev App at app.hot.dev instead.

CI

The GitHub Actions workflow installs the latest Hot CLI with hot-dev/setup-hot and runs:

• hot test in each Hot project demo,
• npm ci && npm run build in hot-chat.
