  Using the repo arcships/rutis, create a TypeScript plugin named <target> with `npx @arcships/rutis-host new <target> --lang node`, install it, and start it with `npx rutis-host dev`. Expected output: the host running the plugin and logging a reload after you change a file. Verify that the reload happens without restarting the host process.

  Using the repo arcships/rutis, run `npx rutis-host check` inside the project at <target>. Expected output: a list of each plugin's dependencies and provided services, or a failure naming a service nothing provides. Verify that adding a provider for the missing service makes the check pass.

• Prototype a capability in Python, then move it to another machine

  Build a Python plugin first, then swap its location or language without changing its callers.

  Using the repo arcships/rutis, create a Python plugin named <target> with `uvx rutis-host new <target> --lang python`, run `uv sync`, then `uv run rutis-host dev`. Expected output: the host running the plugin. Verify that a caller plugin using the service name still resolves after you change the provider's file.

• Add a plugin lifecycle to a Rust application

  Run plugins in a Rust program that starts once dependencies are ready and cleans up on stop.

  Using the repo arcships/rutis, add the rutis and tokio crates to <target> with `cargo add rutis` and `cargo add tokio --features full`, then run `cargo run -p rutis --example quickstart` from a clone. Expected output: the listener printing a greeting, then printing a new greeting after the provider is replaced. Verify that the listener restarts without any change to its own code.

How to use Rutis

1. Check you have what it needs: Node.js with npm, or Bun, for the TypeScript path; uv for the Python path; Go for the Go path.
2. Open arcships/rutis on GitHub and read the README and license.
3. Run npx @arcships/rutis-host new weather --lang node to create the plugin project.
4. Run cd weather && npm install to install dependencies.
5. Run npx rutis-host dev and edit the plugin file; the host reloads it when files change.

These steps come from our top use case, Iterate on a plugin without restarting the host, which also has a copy-paste agent prompt.
