# Composed handbook

> A handbook composed from two chapter packages, each pinned by its digest, showing how MOCA assembles larger packages from modules.

Source: https://openmoca.org/examples/handbook/

**Download** all three, since the handbook needs its chapters:
[`handbook.moca`](https://github.com/openmoca/moca-spec/releases/latest/download/handbook.moca), [`handbook-incident-response.moca`](https://github.com/openmoca/moca-spec/releases/latest/download/handbook-incident-response.moca) and
[`handbook-service-ownership.moca`](https://github.com/openmoca/moca-spec/releases/latest/download/handbook-service-ownership.moca), from the [latest release](https://github.com/openmoca/moca-spec/releases/latest).

`handbook/` has no content of its own. It lists two chapter packages as
`members`, each pinned by its canonical digest, so the handbook's own digest
fixes exactly which chapter bytes it contains.

A Reader resolves members through a host-supplied resolver and refuses a
member whose digest does not match its pin:

```sh
npx @openmoca/moca-lint lint examples/handbook/handbook --members examples/handbook
```

The pins are kept current by `npm run refresh:derived`.

## Try it

To try them with your AI assistant, use our [MCP server](/tools/mcp/). Download [`handbook.moca`](https://github.com/openmoca/moca-spec/releases/latest/download/handbook.moca), [`handbook-incident-response.moca`](https://github.com/openmoca/moca-spec/releases/latest/download/handbook-incident-response.moca) and [`handbook-service-ownership.moca`](https://github.com/openmoca/moca-spec/releases/latest/download/handbook-service-ownership.moca) into one folder, and serve the folder:

```sh
moca-mcp --library .
```

One download with nothing to install, for Windows, macOS or Linux: [get moca-mcp](/tools/mcp/#install).

Connect it to Claude Desktop, Claude Code, VS Code or Cursor, with full paths, as in [Got a .moca file?](/start/open-a-package/#connect-it). Then ask: "What must happen before we declare an incident? Cite the steps in order."
