Should my app import @monorch/runtime?

No. Import @monorch/ai. Runtime is a dependency of the AI package.

Where does Rust live?

engine/ in the monorepo. bindings/node is the N-API crate that publishes as @monorch/runtime.

What if the native binary is missing?

Build fails or load throws at import time. Run pnpm build:native for your platform.

`@monorch/runtime`

N-API binding to the Rust engine. No business logic in this package. Application code should use @monorch/ai; this page is for build and FFI context.

Role

Loads the platform native binary and exposes an Engine class. @monorch/ai wraps it via getRuntime() for schema parse, tool prepare, agent steps, and graph advance.

Build

shell

bash

pnpm build:native   # from monorepo root
# requires rustc/cargo + Node >= 20

Surface (via @monorch/ai)

getRuntime(): Returns the shared Engine instance used by tools, agents, and graphs.
NativeEngine: Constructor from the binding. Prefer getRuntime() over constructing yourself.

Architecture: Architecture. Primary API: @monorch/ai.
