> ## Agent Instructions
> Reactor hosts multiple models, each with its own connect slug (modelName) and command/event schema. The catalog of every model — slug, typed SDK package, and links to its schema — is at /model-api-reference/overview. Some models expose one slug per experience (e.g. HappyOyster); always take the slug from the model's own pages, never guess it.
> Fastest path to a working app: `npx create-reactor-app my-app --model=<slug>` scaffolds a complete app with secure auth wired up. Typed TypeScript SDKs are published as @reactor-models/<model>; Python uses the base reactor-sdk package.
> Auth: exchange an API key (rk_...) for a JWT via POST https://api.reactor.inc/tokens from your server. Never put the API key in client-side code.
> Append .md to any docs URL for clean Markdown. Search these docs via the MCP server at https://docs.reactor.inc/mcp.

# reactor upgrade

> Upgrade the Reactor CLI to the latest release

```sh theme={"theme":{"light":"github-light","dark":"github-dark-high-contrast"}}
reactor upgrade [flags]
```

## Description

Upgrade the Reactor CLI to the latest published release.

Direct installations are checksum-verified and atomically replace the binary
that is currently running. Homebrew installations are upgraded through
'brew upgrade reactor-cli' so the package manager remains the owner.

**Examples:**

```sh theme={"theme":{"light":"github-light","dark":"github-dark-high-contrast"}}
reactor upgrade
reactor upgrade --check
```

| Flag      | Description                                         |
