The CLI example

examples/cli — a host with no browser in it.

The Python tier's provide_cli hook lets a plugin contribute commands to a command-line application, and provide_slash_commands does the same for an interactive session — a terminal, a prompt, a command palette. This example is a host and a weather plugin, and nothing else.

pip install -e .
python examples/cli/host.py

File	What it shows
host.py	a PluginPlatform in a program that is not a server
weather_plugin.py	provide_cli, and a manifest that describes itself

See extending the command line for the reactor command itself — this example is the same mechanism with a host you write. The commands provide_slash_commands registers are described under the command registry.

It is worth reading precisely because it has no frontend: the constructs on the Python runtime pages are not a mirror of the browser's, they are the model — and this is the model with the browser removed.
