LangBot/plugins/misc/HelloPlugin/SHARED_RUNTIME.md

Shared runtime source candidate (SDK >=0.7.4)

This source declares sharedRuntime: shared-runtime-v1 and componentModel: stateless-v1. It is source-reviewed for the multi-tenant contract; it is not certified and makes no claim of live tenant acceptance.

• Configuration is read per invocation with self.get_config() / self.get_plugin_config(). HelloPlugin declares no config items (spec.config: []), so the shared worker never reads tenant settings; nothing from an installation is copied onto the plugin, the components or module globals.
• initialize() is empty, so a shared worker is never initialized with another installation's settings.

Per invocation

• GetWeatherAlerts.call builds the NWS URL from its arguments and creates a fresh httpx.AsyncClient for every request (components/tools/get_weather_alerts.py); no client, response or parameter is cached on the shared tool object.
• DefaultEventListener's handler only assigns event_context.event.user_message_alter on the event it received; it keeps no state across events.
• Info builds its reply from the ExecuteContext of the current command invocation.
• No SDK process-global settings are modified.

Identity

No upstream/tenant identity is derived: the plugin exposes no per-user vendor state and calls no identity-scoped Host API.

Tests

tests/test_shared_runtime.py drives one plugin/component object graph across two distinct InstallationBinding values with the real SDK bind_invocation(...) and InstallationBinding, and asserts (a) the shared tool resolves the invocation config and produces installation-independent results while retaining no attributes, and (b) the listener mutates only the per-event context. HTTP replies are simulated; no live network or vendor account is used.

Known limits

• spec.config is empty: there are no installation settings to resolve, and the shared and dedicated paths behave identically.
• No claim of certification; independent review and two-Workspace invocation acceptance are still required.
